The Perfect Server - CentOS 5.10 x86_64 [ISPConfig 3] - Page 5
10 Install Dovecot
There's a Dovecot package in the CentOS repository, but unfortunately it doesn't support MySQL. Therefore we must remove the existing Dovecot and install another Dovecot package (from ATrpms) which comes with MySQL support.
yum remove dovecot
Create a new file /etc/yum.repos.d/atrpms.repo...
... and insert the following lines into the the file:
[atrpms] name=Red Hat Enterprise Linux 5 - $basearch - ATrpms baseurl=http://dl.atrpms.net/el5-$basearch/atrpms/stable failovermethod=priority exclude=dovecot-2* includepkgs=dovecot dovecot-sieve # # requires stable # [atrpms-testing] name=Red Hat Enterprise Linux 5 - $basearch - ATrpms testing baseurl=http://dl.atrpms.net/el5-$basearch/atrpms/testing failovermethod=priority enabled=1 exclude=dovecot-2* includepkgs=dovecot dovecot-sieve # # requires stable and testing # [atrpms-bleeding] name=Red Hat Enterprise Linux 5 - $basearch - ATrpms bleeding baseurl=http://dl.atrpms.net/el5-$basearch/atrpms/bleeding failovermethod=priority enabled=0
Then import tge gpg key of the atrpm repository...
rpm --import RPM-GPG-KEY.atrpms
...and install Dovecot:
yum -y install dovecot dovecot-sieve
On a 64-bit system, also do this (don't do this on a 32-bit system!):
ln -s /usr/lib64/dovecot/ /usr/lib/dovecot
Now we create the system startup links for Dovecot:
chkconfig --levels 235 dovecot on
11 Install Postfix With MySQL Support
The "normal" Postfix package from the CentOS repository doesn't have MySQL, but the Postfix package from the CentOS Plus repository does. Therefore we remove Postfix...
yum -y remove postfix
... and install it again, this time from the CentOS Plus repository:
yum -y install postfix
Then turn off Sendmail and start Postfix and MySQL:
chkconfig --levels 235 mysqld on
chkconfig --levels 235 sendmail off
chkconfig --levels 235 postfix on
12 Install Getmail
Getmail can be installed as follows:
yum -y install getmail
Note: If getmail is not present then use the following command to install the same.
cd /tmp ; wget http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/getmail-4.20.4-1.el5.rf.noarch.rpm ; rpm -ivh getmail-4.20.4-1.el5.rf.noarch.rpm
13 Set MySQL Passwords And Configure PHPMyAdmin
Set passwords for the MySQL root account:
[root@server1 tmp]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] <-- ENTER
New password: <-- yourrootsqlpassword
Re-enter new password: <-- yourrootsqlpassword
Password updated successfully!
Reloading privilege tables..
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
Remove anonymous users? [Y/n] <-- ENTER
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] <-- ENTER
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] <-- ENTER
- Dropping test database...
- Removing privileges on test database...
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] <-- ENTER
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Now we configure phpmyadmin. We change the Apache configuration so that 249 allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):
# # Web application to manage MySQL # #<Directory "/usr/share/phpmyadmin"> # Order Deny,Allow # Deny from all # Allow from 127.0.0.1 #</Directory> Alias /phpmyadmin /usr/share/phpmyadmin Alias /PHPMyAdmin /usr/share/phpmyadmin Alias /mysqladmin /usr/share/phpmyadmin
Next we change the authentication in phpmyadmin from cookie to http:
[...] /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'http'; [...]
Then we create the system startup links for Apache and start it:
chkconfig --levels 235 httpd on
Now you can direct your browser to http://server1.example.com/phpmyadmin/ or http://192.168.0.100/phpmyadmin/ and log in with the user name root and your new root MySQL password.
14 Install Amavisd-new, SpamAssassin And ClamAV
To install amavisd-new, spamassassin and clamav, run the following command:
yum install amavisd-new spamassassin clamav clamd unzip bzip2 unrar perl-DBD-mysql
... and uncomment the line CONFIG_FILE="/etc/amavisd.conf":
### Uncomment this if you want to use amavis with sendmail milter interface. ### See README.milter for details. # #MILTER_SOCKET="local:/var/amavis/amavis-milter.sock" #MILTER_SOCKET="firstname.lastname@example.org" ### These are other defaults. #AMAVIS_ACCOUNT="amavis" CONFIG_FILE="/etc/amavisd.conf" #MILTER_FLAGS=""
Then we start freshclam, amavisd, and clamd...
chkconfig --levels 235 amavisd on
chkconfig --levels 235 clamd on
... and create some necessary directories:
mkdir /var/run/amavisd /var/spool/amavisd
chown amavis /var/run/amavisd /var/spool/amavisd /var/spool/amavisd/tmp /var/spool/amavisd/db
ln -s /var/run/clamav/clamd.sock /var/spool/amavisd/clamd.sock
