Sissejuhatus

ISPConf 3 on veebiliidese kaudu kasutatav veebimajutuse kontrollkeskkond, mis võimaldab hallata ja konfigigureerida mitmeid teenuseid nagu näiteks: apache2 või nginx veebiserver, Postfix mailserver, Courier või Dovecot IMAP/POP3 server, MySQL, BIND või MyDNS nimeserver, PureFTPd, SpamAssasin jms.

Eelkõige on ISPConf suunatud veebimajutus teenuse pakkujatele.

Veebiliidesele juurdepääs on võimalik 3-l tasemel:

  • administraatoritel
  • edasimüüjatel
  • klientidel.

Internetis on tutvumiseks olemas ka juurdepääs demoversioonile aadressil: http://demo3.ispconfig.org/

Administraatorina saad siseneda, kasutades login: admin ja password: demo

Edasimüüjana sisenedes kasuta: login: reseller ja password: demo

Kliendina kasuta: login: client ja password: demo.

Alljärgnev juhend õpetab teid, kuidas Ubuntu serveriga (13.04) virtuaalmasinat ettevalmistada ISPConf 3 installeerimiseks. Veebiserverina kasutame apache2-te, nimeserverina BIND-i ja IMAP/POP3 serverina Dovecot-i.

Virtuaalmasina ettevalmistus ISPConf 3 installeerimiseks

Kõigepealt installeerime Ubuntu serveri (ver. 13.04) Virtualboxi. Virtualboxis eraldame loodavale serverile 1024 MB mälu, loome virtuaalse dünaamilise kõvaketta ja 2 võrguadapterit. Esimese võrguadapteri ühendame NAT võrguga ja teine host-only adapter virtuaalsete ühenduste tarvis. Serveri paigaldamise käigus paigaldame ühtlasi ka OpenSSH serveri, et hiljem oleks lihtsam desktop arvutilt serveriga ühendust luua.

Võrgu seadistus

Kuna server vajab püsivat IP aadressi, siis teeme meie võrguadapterite seadistustes järgmised muudatused. Kõigepealt muudame /etc/network/interfaces faili sisu. Meie kasutasime selleks tekstiredaktorit nano. 

nano /etc/network/interfaces

Selline peab olema faili /etc/network/interfaces sisu. 

  The loopback network interface
  auto lo 
  iface lo inet loopback  
  The primary network interface
  auto eth0 
  iface eth0 inet dhcp
 
  auto eth1 
  iface eth1 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        dns-nameservers 8.8.8.8 8.8.4.4

Peale võrgu seadistuse muutmist, tuleb teha restart võrguseadistustele. Selleks sisestame terminali 

/etc/init.d/networking restart

Järgnevalt teeme muudatused /etc/hosts faili. Kuna andsime oma serveri nimeks server1 ja domeeninimeks pingviin.com, siis peame lisama /etc/hosts faili rea 192.168.0.100 --->server1.pingviin.com---> server1. 

nano /etc/hosts

/etc/hosts faili sisu on järgmine 

127.0.0.1       localhost.localdomain   localhost 
192.168.0.100   server1.pingviin.com    server1 

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback 
fe00::0 ip6-localnet 
ff00::0 ip6-mcastprefix 
ff02::1 ip6-allnodes 
ff02::2 ip6-allrouters

Muudame failis /etc/hostname järgmise käsuga masina nime 

echo server1.pingviin.com > /etc/hostname

Seejärel teeme teenusele restardi 

/etc/init.d/hostname restart

Järgnevate käskudega saame kontrollida, kas kõik siiamaani toimib. 

hostname
hostname –f

Mõlema käsu puhul peab väljundiks tulema 

server1.pingviin.com

/etc/apt/sources.list faili modifitseerimine

Kontrollime, et failis /etc/apt/sources.list oleksid lubatud universe and multiverse repositooriumid. 

nano /etc/apt/sources.list

Peale seda värskendame repositooriumid käsuga: 

apt-get update

ja paigaldame viimased uuendused: 

apt-get upgrade

Peale uuenduste paigaldamist, tuleb teha serverile restart 

reboot

Shelli vahetamine

Kuna meil on vaja serveris kasutada /bin/bash-i, mitte /bin/dash-i , siis shelli vahetamiseks kasutame käsku. 

dpkg-reconfigure dash

Vastus küsimusele on värviliselt välja toodud. 

Use dash as the default system shell (/bin/sh)? <--No

Kui me shelli ei vahetaks, siis ISPConfig`i install ei õnnestu, sest ISPConfigi paigaldamisel kasutatakse skripte, mis /bin/dash-iga ei käivitu või siis põhjustavad hiljem süsteemi ebastabiilsust.

AppArmor`i väljalülitamine

AppArmor on turvalisuse suurendamiseks loodud moodul (samalaadne SELinuxi-ga). Kuid tihti põhjustab just see süsteemis anomaaliaid, millede tuvastamine võtab kaua aega. Sellepärast on vajalik AppArmor väljalülitada ja ka eemaldada. 

/etc/init.d/apparmor stop
update-rc.d -f apparmor remove
apt-get remove apparmor apparmor-utils

Süsteemi kella sünroniseerimine

On hea tava, et süsteemi kell oleks alati õige, selleks sisestame terminali 

apt-get install ntp ntpdate

Postfix, Dovecot, MySQL, phpMyAdmin, rkhunter, binutils paigaldamine

Järgmisena saame paigaldada Postfix-i, MySQL-i, Dovecot-i, rkhunter-i, binutils ja muu vajaliku käsuga 

apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils 
dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve sudo

Peale käsu sisestamist vasta alljärgnevatele küsimustele: 

New password for the MySQL "root" user: <-- sinurootSQLparool
Repeat password for the MySQL "root" user: <-- sinurootSQLparool
General type of mail configuration: <-- Internet Site
System mail name: <-- server1.pingviin.com

Järgmiseks tuleb Postfix`i master.cf failis submission ja smtps sektsioonides trellid eest ära võtta. Read mille ees trelle olla ei tohi on rohelised. 

nano /etc/postfix/master.cf


...
submission inet n       -       -       -       -       smtpd
-o syslog_name=postfix/submission
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
-o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
smtps     inet  n       -       -       -       -       smtpd
-o syslog_name=postfix/smtps
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
-o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
...

Peale muudatuste tegemist tuleb Postfix`ile teha restart 

/etc/init.d/postfix restart

Selleks, et MySQL kuulaks kõiki liideseid, mitte ainult 127.0.0.1, tuleb väljakommenteerida bind-address = 127.0.0.1 , nagu allpool näidatud... 

nano /etc/mysql/my.cnf

...
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
# bind-address           = 127.0.0.1
...

Seejärel taaskäivitame MySQL`i 

/etc/init.d/mysql restart

Selleks, et kontrollida võrk on töökorras siseta käsk 

netstat -tap | grep mysql

Väljund peaks välja nägema umbes selline: 

root@server1:~# netstat -tap | grep mysql

tcp        0      0 *:mysql                 *:*                     LISTEN      21298/mysqld

root@server1:~#

Amavisd-new, SpamAssassin, Clamav paigaldamine

Selleks, et paigaldada amavisd-new, SpamAssasin ja Clamav sisestame käsu 

apt-get install amavisd-new spamassassin clamav clamav-daemon zoo unzip bzip2 arj nomarch lzop cabextract 
apt-listchanges libnet-ldap-perl libauthen-sasl-perl clamav-docs daemon libio-string-perl libio-socket-ssl-perl 
libnet-ident-perl zip libnet-dns-perl

Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear ja mcrypt paigaldamine

Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear ja mcrypt istallime järgmise käsuga 

apt-get install apache2 apache2.2-common apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert 
libapache2-mod-php5 php5 php5-common php5-gd php5-mysql php5-imap phpmyadmin php5-cli php5-cgi
libapache2-mod-fcgid apache2-suexec php-pear php-auth php5-mcrypt mcrypt php5-imagick imagemagick
libapache2-mod-suphp libruby libapache2-mod-ruby libapache2-mod-python php5-curl php5-intl php5-memcache
php5-memcached php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc
php5-xsl memcached

Paigalduse käigus näed küsimusi, mille vastused on ära toodud värvilisena. 

Web server to reconfigure automatically: <-- apache2

Configure database for phpmyadmin with dbconfig-common? <-- No

Seejärel siseta järgmine käsk, et aktiveerida Apache mooduleid suexec, rewrite, ssl, actions, ja include 

a2enmod suexec rewrite ssl actions include

ja kui soovid kasutada WebDAV-i, siis tuleb aktiveerida ka moodulid dav, dav_fs ja auth_digest 

a2enmod dav_fs dav auth_digest

Järgmiseks tuleks avada fail /etc/apache2/mods-available/suphp.conf 

nano /etc/apache2/mods-available/suphp.conf

ja selles failis tuleks välja kommenteerida rida <FilesMatch "\.ph(p3?|tml)$">
ja lisame rea AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml , vastasel juhul hakkaks iga PHP fail käivituma suPHP all. 

...
<IfModule mod_suphp.c>
# <FilesMatch "\.ph(p3?|tml)$">
   #    SetHandler application/x-httpd-suphp
   #</FilesMatch>
      AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml
      suPHP_AddHandler application/x-httpd-suphp
...

Teeme Apache`le restardi, et tehtud muudatused saaksid jõustuda 

/etc/init.d/apache2 restart

Nüüd muudame /etc/mime.types faili selleks, et Ruby failid laiendiga .rb oleksid samuti toetatud. 

nano /etc/mime.types

Selleks peame failis välja kommentaarima järgmise rea application/x-ruby 

...
# application/x-ruby                             rb
...

Teeme Apache`le uuesti restardi, et tehtud muudatused saaksid jõustuda 

 /etc/init.d/apache2 restart

Xcache

Xcache on PHP koodi kiirendi selleks, et kiirendada ja optimeerida PHP koodi. See on vägagi soovitatud, et oleks installeeritud PHP kiirendaja selleks et PHP lehed kiiremini laeksid. Selleks sisestame terminalis 

apt-get install php5-xcache

ja teeme Apache`le restardi 

/etc/init.d/apache2 restart

PHP-FPM

Alates ISPConfig 3.0.5 versioonist kasutatakse seal koos apachega eraldi PHP modulit : PHP-FPM.

Et seda PHP-FPM moodulit koos Apachega kasutada, vajame apache moodulit mod_fastcgi

PHP-FPM ja apache mooduli mod_fastcgi saame installida käsuga: 

apt-get install libapache2-mod-fastcgi php5-fpm

Aktiveerime mooduli 

a2enmod actions fastcgi alias

Teeme Apache`le restardi. 

/etc/init.d/apache2 restart

Mailman

Alates versioonist 3.0.4, ISPConfig võimaldab ka hallata (luua/muuta/kustutada) Mailman maili nimekirju. Kui soovid seda võimalust kasutada, siis saad paigaldada Mailman'i järgneva käsuga: 

apt-get install mailman

Installi käigus tuleb valida keel 

Languages to support: <-- en    
Missing site list <-- Ok

Selleks, et saaks Mailman`i käivitada tuleb luua maili nimekiri nimega mailman 

newlist mailman

Terminal väljastab järneva jutu, kus pead sisestama ka mailmani listi haldava administraatori emaili aadressi ja ka salasõna 

root@server1:~# newlist mailman
 Enter the email of the person running the list: <-- administaatori emaili aadress, näit. listadmin@pingviin.com
 Initial mailman password: <-- administraatori password mailmani listi jaoks
 To finish creating your mailing list, you must edit your /etc/aliases (or
 equivalent) file by adding the following lines, and possibly running the
`newaliases' program:

## mailman mailing list
mailman:              "|/var/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/var/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/var/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/var/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/var/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/var/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/var/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/var/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/var/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe mailman"

Hit enter to notify mailman owner... <-- ENTER

root@server1:~#

Avame faili /etc/aliases 

nano /etc/aliases

ja lisame sinna vajalikud read 

...
## mailman mailing list
mailman:              "|/var/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/var/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/var/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/var/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/var/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/var/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/var/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/var/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/var/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe mailman"

Käivitame lisatud aliased 

newaliases

ja teeme Postfix`ile restardi 

/etc/init.d/postfix restart

Aktiveerime Mailman`i Apache konfiguratsiooni. 

ln -s /etc/mailman/apache.conf /etc/apache2/conf.d/mailman.conf

seejärel teeme Apache`le restardi 

/etc/init.d/apache2 restart

ning käivitame Mailman deemoni. 

/etc/init.d/mailman start

PureFTPd ja Quota

PureFTP ja Quota paigaldame järgmise käsuga 

apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool

Modifitseerime /etc/default/pure-ftpd-common faili 

nano /etc/default/pure-ftpd-common

ja veendume, et failis oleksid järgmised kirjed STANDALONE_OR_INETD=standalone ja VIRTUALCHROOT=true 

...
STANDALONE_OR_INETD=standalone
...
VIRTUALCHROOT=true
...

Järgmiseks konfigureerime PureFTPd, et lubada FTP ja TLS sessioone. FTP on väga ebaturvaline protoko, sest kõik salasõnad ja kogu andmevahetus toimub avatekstiga. Kasutades TLS protokolli saame andmevahetuse muuta turvaliseks, sest kogu andmevahetus krüpteeritakse.

Et seadistada PureFTPd, kasutama TLS sesioone anname terminali käsu 

echo 1 > /etc/pure-ftpd/conf/TLS

Selleks, et kasutada TLS`i tuleb luua SSL sertifikaat ja koht kuhu sertifikaat salvestada. Selleks loome kõigepealt vajaliku kausta 

mkdir -p /etc/ssl/private/

ja seejärel genereerime SSL sertifikaadi sisestades terminali: 

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out 
/etc/ssl/private/pure-ftpd.pem

Sertifikaati luues küsitakse teilt andmeid. Näidis vastused küsimustele allpool värviliselt: 

Country Name (2 letter code) [AU]: <-- EE
State or Province Name (full name) [Some-State]: <-- Harju
Locality Name (eg, city) []: <-- Tallinn
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <-- Pingviin AS
Organizational Unit Name (eg, section) []: <-- IT
Common Name (eg, YOUR name) []: <-- server1.pingviin.com
Email Address []: <-- nimi@pingviin.com

SSL sertifikaadi õiguste muutmine 

chmod 600 /etc/ssl/private/pure-ftpd.pem

Teeme PureFTPd`le restardi 

/etc/init.d/pure-ftpd-mysql restart

Et saaks kasutada Quota't peame muutma /etc/fstab faili. 

nano /etc/fstab


# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/mapper/server1--vg-root /               ext4    errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0       1

/dev/mapper/server1--vg-swap_1 none            swap    sw              0       0

Aktiveerime quota järgnevate käskudega 

mount -o remount /
quotacheck -avugm
quotaon –avug

BIND DNS Server

BIND9 nimeserveri saame paigaldada järgneva käsuga 

apt-get install bind9 dnsutils

Vlogger, Webalizer ja AWstats

Vlogger, Webalizer ja AWstats installitakse järgmiselt: 

apt-get install vlogger webalizer awstats geoip-database libclass-dbi-mysql-perl

Seejärel avame faili /etc/cron.d/awstats ja kommenteerime välja kogu sisu. 

nano /etc/cron.d/awstats

#MAILTO=root

#*/10 * * * * www-data [ -x /usr/share/awstats/tools/update.sh ] && /usr/share/awstats/tools/update.sh
 
# Generate static reports:
#10 03 * * * www-data [ -x /usr/share/awstats/tools/buildstatic.sh ] && /usr/share/awstats/tools/buildstatic.sh

Jailkit

Jailkit on vajalik üksnes siis kui tahetakse SSH kasutajaid chroot'ida ehk muuta nende kasutajate root directory 't.

TÄHTIS! - Jailkit tuleb paigaldada enne ISPConfig 3 paigaldust. Kui ISPConfig on juba paigaldatud, siis Jailkiti paigaldamine ei õnnestu!

Jailkit saab paigaldada viies lädi järgmised operatsioonid. 

apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.15.tar.gz
tar xvfz jailkit-2.15.tar.gz
cd jailkit-2.15
./debian/rules binary

cd ..
dpkg -i jailkit_2.15-1_*.deb
rm -rf jailkit-2.15*

fail2ban

Fail2ban'i paigaldamine on kasutaja äranägemisel, kuid soovitatav, sest ISPConfig proovib monitoorida neid logisid. 

apt-get install fail2ban

Selleks, et fail2ban monitooriks PureFTPd ja Dovecot`i, loome faili /etc/fail2ban/jail.local 

nano /etc/fail2ban/jail.local


[pureftpd]
enabled  = true
port     = ftp
filter   = pureftpd
logpath  = /var/log/syslog
maxretry = 3

[dovecot-pop3imap]
enabled = true
filter = dovecot-pop3imap
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5

[sasl]
enabled  = true
port     = smtp
filter   = sasl
logpath  = /var/log/mail.log
maxretry = 3

Loome järgmised 2 filterfaili. 

nano /etc/fail2ban/filter.d/pureftpd.conf


[Definition]
failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.*
ignoreregex =


nano /etc/fail2ban/filter.d/dovecot-pop3imap.conf


[Definition]
failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
ignoreregex =

Seejärel teeme fail2ban`ile restardi 

/etc/init.d/fail2ban restart

SquirrelMail

Et paigaldada SquirrelMail'i Webmail klienti anname terminalis käsu: 

apt-get install squirrelmail

Seejärel seadistame SquirrelMail`i 

squirrelmail-configure

Peame SquirreMaili seadistama, et kasutada Dovecote-IMAP/POP3 serverit.

SquirrelMail Configuration : Read: config.php
---------------------------------------
While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others.  If you select your IMAP server, this option will
set some pre-defined settings for that server.
Please note that you will still need to go through and make sure
everything is correct.  This does not change everything.  There are
only a few settings that this will change.
Please select your IMAP server:
   bincimap    = Binc IMAP server
   courier     = Courier IMAP server
   cyrus       = Cyrus IMAP server
   dovecot     = Dovecot Secure IMAP server
   exchange    = Microsoft Exchange IMAP server
   hmailserver = hMailServer
   macosx      = Mac OS X Mailserver
   mercury32   = Mercury/32
   uw          = University of Washington's IMAP server
   gmail       = IMAP access to Google mail (Gmail) accounts
   quit        = Do not change anything

Nüüd seadistame SquirrelMail`i selliselt, et seda saaks kasutada kas squirrelmail või webmail aliastega. 

cd /etc/apache2/conf.d/
ln -s ../../squirrelmail/apache.conf squirrelmail.conf
/etc/init.d/apache2 reload

Avame faili /etc/apache2/conf.d/squirrelmail.conf 

nano /etc/apache2/conf.d/squirrelmail.conf

Lisada sinna read, mis on märgitud punase kirjaga

... <Directory /usr/share/squirrelmail>

...

Loome kausta /var/lib/squirrelmail/tmp ja lisame omanikuks www-data 

mkdir /var/lib/squirrelmail/tmp
chown www-data /var/lib/squirrelmail/tmp

Teeme Apache`l restardi 

/etc/init.d/apache2 reload

Nüüd saad SquirrelMail`i kätte kui sisestad brauserisse 

http://192.168.0.100/squirrelmail

Kui soovid kasutada /webmail, mitte /squirrelmail, tuleb lisada alias vastavalt all toodud näitele. 

nano /etc/apache2/conf.d/squirrelmail.conf

Alias /squirrelmail /usr/share/squirrelmail
Alias /webmail /usr/share/squirrelmail
...

Teeme Apache`le restardi 

/etc/init.d/apache2 reload

Nüüd saad Squirrelmail`i siseneda 

http://192.168.0.100/webmail

Kui soovida teha virtual host nimega webmail.pingviin.com, toimi järgmiselt. 

nano /etc/apache2/conf.d/squirrelmail.conf

...
<VirtualHost 192.168.0.100:80>
 DocumentRoot /usr/share/squirrelmail
 ServerName webmail.pingviin.com
</VirtualHost>

Teeme Apache`le restardi 

/etc/init.d/apache2 reload

Nüüd saad SquirrelMail`i siseneda.

Kokkuvõte

Ülo

Kokkuvõtteks võib öelda, et ISPConf on maailmas päris laialt kasutusel ja infot selle kohta saab kasutajate foorumitest. Kuna kasutajate kommuune on palju, siis võib uskuda, et probleemi tekkides leiab vastuse alati. Mis aga on pisut kummastav, on see, et ISPConfigi seadistamise manuaal on küll netist allalaetav, kuid 1 allalaadimine maksab 5.- €.

Kogu süsteemi installeerimine võtab küll aega, aga kui teha täpselt juhendi järgi, siis ei peaks eriti probleeme tekkima. Kuna antud viki sai koostatud õppimise eesmärkidel, siis võib küll öelda, et selle projekti käigus sai vähemalt mulle selgeks, et selline süsteem koosneb väga paljudest erinevatest tarkvaradest ja nende omavaheline sobivus on häireteta töö aluseks. Seetõttu peab alati enne taolise süsteemi installeerimist kindlaks tegema oma vajadused ning seejärel uurima, kuidas antud süsteem saab sinu vajadused kõiga paremini rahuldatud.

Aare

ISPConf puhul oli tegemist meie jaoks väga mahuka väljakutsega ja sellele kulus ka omajagu aega. Lõpuks õnnestus teenus ka ilusti tööle saada. Suur abi oli grupitööst meile mõlemile, mõne asja peale tulin mina, mõne asja peale Ülo. Üldiselt oli väga sobilik grupitöö variant, kuna üksinda tehes oleksin valinud vähem mahukama teenuse. Julgeksin soovitada seda meie koostatud juhendit inimesele, kes pole antud teenusega kursis, kuna kõik on väga üksikasjalikult lahtikirjutatud ja peaks olema mõistetav kõigile. Üks asi mis mind üllatas oli see, kui paljudest väikestest ja suurtest osadest mingi teenus kokku tuleb panna, et kõik töötaks ja midagi omavahel konflikti ei läheks. Seega kõik sellised suure teenuse paigaldused peaksid jälgima kindlat paikapandud süsteemi, et saavutada korduvalt sama tulemus, näiteks süsteemi taaste või teisele serverile kolimise korral. Sellise mahuga teenuse puhul, kui seda on vaja korduvalt paigaldada, tuleks kindlasti eelistad scripti, mis lühendaks paigalduseks kuluvat aega ja samuti välistaks inimlikud eksimused, näiteks kirjavigade näol.
