If you see other packages, such as '''perl''' or '''php''', '''abort the installation'''. This might occur because you have installed '''perl-CGI-Session''' or '''perl-DBD-Pg'''. These two packages might be on your system because you have installed '''otrs''' or another aplication. You can check if they are still needed:
+
yum --enablerepo=smecontribs,pgsql13 install smeserver-postgresql

If that answers no packages need ... you can safely remove these packages

exit
 
 
 
Edit the file '''/etc/e-smith/templates-custom/var/lib/pgsql/data/postgresql.conf''' remove # and change the following settings:
 
 
 
superuser_reserved_connections=2
 
ssl = on
 
password_encryption = on
 
listen_addresses = 'localhost'
 
 
 
Then copy your server SSL keys:
 
 
 
cd /var/lib/pgsql/data
 
cp /etc/httpd/conf/ssl.crt/server.crt .
 
cp /etc/httpd/conf/ssl.key/server.key .
 
chown postgres:postgres server.*
 
 
 
Edit the file '''/etc/e-smith/templates-custom/var/lib/pgsql/data/pg_hba.conf''' and change the following settings:
 
 
 
local    all  all                    md5
 
host    all  all    127.0.0.1/32    md5
 
host    all  all    ::1/128        md5
 
 
 
and add at the end:
 
 
 
host    all    all    0.0.0.0 255.255.255.255  reject
 
 
 
 
'''Be sure to add an extra white line at the end.That why you got an extra line on above box!'''
 
 
 
Expand template:
 
 
 
expand-template /var/lib/pgsql/data/pg_hba.conf
 
expand-template /var/lib/pgsql/data/postgresql.conf
 
 
 
Restart with new settings:
 
 
 
/etc/init.d/postgresql stop
 
/etc/init.d/postgresql start
 
 
 
and add the symlinks to start automatically:
 
 
 
ln -s /etc/init.d/postgresql /etc/rc.d/rc7.d/S56postgresql
 
ln -s /etc/init.d/postgresql /etc/rc.d/rc6.d/K03postgresql
 
 
 
To ensure everything is all right:
 
 
 
signal-event post-upgrade
 
signal-event reboot
 
 
 
===Testing your environment===
 
To test if you have set postgres password correctly:
 
 
 
su postgres
 
  psql -U postgres -d template1
 
 
 
and enter the password you have set above. If all is correct, you should enter the postgres console. Then exit:
 
 
 
\q
 
 
 
and exit from postgres user:
 
 
 
exit
