6 MySQL

In order to install MySQL, we run

yast2 -i mysql mysql-client mysql-shared perl-DBD-mysql perl-DBI perl-Data-ShowTable mysql-devel

Then we add the system startup links for MySQL and start it:

chkconfig --add mysql
/etc/init.d/mysql start

Now check that networking is enabled. Run

netstat -tap

In the output you should see a line like this one:

[...]
tcp        0      0 *:mysql                 *:*                     LISTEN      4298/mysqld
[...]

If you don't see a line like this, edit /etc/my.cnf, comment out the option skip-networking:

vi /etc/my.cnf

[...]#skip-networking
[...]

and restart your MySQL server:

/etc/init.d/mysql restart

Run

mysqladmin -u root password yourrootsqlpassword
mysqladmin -h server1.example.com -u root password yourrootsqlpassword

to set a password for the user root (otherwise anybody can access your MySQL database!).

 

7 Postfix With SMTP-AUTH And TLS

Postfix is already installed, but we must install Cyrus-SASL now:

yast2 -i cyrus-sasl cyrus-sasl-crammd5 cyrus-sasl-digestmd5 cyrus-sasl-gssapi cyrus-sasl-otp cyrus-sasl-plain cyrus-sasl-saslauthd

Then we add the system startup links for saslauthd and start it:

chkconfig --add saslauthd
/etc/init.d/saslauthd start

Afterwards we create the certificates for TLS:

mkdir /etc/postfix/ssl
cd /etc/postfix/ssl/
openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024
chmod 600 smtpd.key
openssl req -new -key smtpd.key -out smtpd.csr
openssl x509 -req -days 3650 -in smtpd.csr -signkey smtpd.key -out smtpd.crt
openssl rsa -in smtpd.key -out smtpd.key.unencrypted
mv -f smtpd.key.unencrypted smtpd.key
openssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650

Next we configure Postfix for SMTP-AUTH and TLS:

postconf -e 'mydomain = example.com'
postconf -e 'myhostname = server1.$mydomain'
postconf -e 'mynetworks = 127.0.0.0/8'
postconf -e 'smtpd_sasl_local_domain ='
postconf -e 'smtpd_sasl_auth_enable = yes'
postconf -e 'smtpd_sasl_security_options = noanonymous'
postconf -e 'broken_sasl_auth_clients = yes'
postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,check_relay_domains'
postconf -e 'inet_interfaces = all'
postconf -e 'alias_maps = hash:/etc/aliases'
postconf -e 'smtpd_tls_auth_only = no'
postconf -e 'smtp_use_tls = yes'
postconf -e 'smtpd_use_tls = yes'
postconf -e 'smtp_tls_note_starttls_offer = yes'
postconf -e 'smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key'
postconf -e 'smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt'
postconf -e 'smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem'
postconf -e 'smtpd_tls_loglevel = 1'
postconf -e 'smtpd_tls_received_header = yes'
postconf -e 'smtpd_tls_session_cache_timeout = 3600s'
postconf -e 'tls_random_source = dev:/dev/urandom'

To enable TLS connections in Postfix, edit /etc/postfix/master.cf and uncomment the tlsmgr line so that it looks like this one:

vi /etc/postfix/master.cf

[...]
tlsmgr    unix  -       -       n       1000?   1       tlsmgr
[...]

Now restart Postfix:

/etc/init.d/postfix restart

To see if SMTP-AUTH and TLS work properly now run the following command:

telnet localhost 25

After you have established the connection to your Postfix mail server type

ehlo localhost

If you see the lines

250-STARTTLS

and

250-AUTH

then everything is fine.

On my system the output looks like this:

server1:/etc/postfix/ssl # telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 server1.example.com ESMTP Postfix
ehlo localhost
250-server1.example.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
quit
221 2.0.0 Bye
Connection closed by foreign host.
server1:/etc/postfix/ssl #

Type

quit

to return to the system's shell.

 

8 Courier-IMAP/Courier-POP3

I want to use a POP3/IMAP daemon that has Maildir support. That's why I use Courier-IMAP and Courier-POP3.

yast2 -i courier-imap fam-server courier-authlib expect tcl

Afterwards we add the system startup links and start POP3, IMAP, POP3s and IMAPs:

chkconfig --add fam
chkconfig --add courier-authdaemon
chkconfig --add courier-pop
chkconfig --add courier-imap
/etc/init.d/courier-pop start
/etc/init.d/courier-imap start
chkconfig --add courier-pop-ssl
chkconfig --add courier-imap-ssl
/etc/init.d/courier-pop-ssl start
/etc/init.d/courier-imap-ssl start

If you do not want to use ISPConfig, configure Postfix to deliver emails to a user's Maildir*:

postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

*Please note: You do not have to do this if you intend to use ISPConfig on your system as ISPConfig does the necessary configuration using procmail recipes. But please go sure to enable Maildir under Management -> Server -> Settings -> EMail in the ISPConfig web interface.
