I run a SuSE 11 internet server providing some basic services.
I recently had to upgrade to a new version of SuSE (11.3) and it took my quite some time to do so.
Therefore I am listing here the necessary steps, hoping that the next time I will spend less time on such an upgrade…
- dovecot IMAP/IMAPS Mail Server
- dovecot POP3/POP3S Mail Server
- postfix SMTP TLS MTA
- Apache HTTP/HTTPs Webserver
- Subversion Repository
- WebDAV online Disk
- BIND DNS
Preparations and basic setup
- Take the server off-line and make sure no mail arrives. The emails will be queued on the alternate MX and delivered later.
- Do the backup (
rsyncincluding all deletions)
- Dump the installed packes to an XML using
- Install base software from boot ISO over the network
- Setup Networking
/homein the background
Setup Mail Server
- Setup postfix (check possibility to restore
/etc/sysconfig/postfixfrom backup), but do not start
- Setup dovecot (restore
/etc/dovecot/dovecot.conf), but do not start
- Check certificate values in
/etc/sysconfig/postfix(or restore from backup)
- Create postfix certificates and SSL CA using
- Edit the config file
/usr/share/doc/packages/dovecot/dovecot-openssl.cnf(attention, will be overwritten when upgrading dovecot)
- Download and install roundcube mail in
Setup Apache Webserver
- Setup apache2 (check possibility to restore
- Generate the following certificates for apache using
yast2(mail, svn, disk)
- Export the PEM encoded certificates to
Setup BIND Name Server
- If subversion is the same version (or compatible) just restore /srv/svn from backup
- If subversion is not compatible anymore use
svnadmin loadto load the dump from the backup
There’s noting to do for the WebDAV disk 🙂
After all the configuration files etc. have been restored and the settings in
/etc/sysconfig have been checked, run SuSEconfig for the last time and test the mail server.
Unplug from the internet and start postfix and dovecot.
Check if a locally created mail is correctly handled by postfix, amavis and successfully delivered with dovecot.
Also check if the IMAP mbox is created in
If this test succeeds we can restore
/var/spool/mail from backup and connect to the internet again.
yast2 to edit the runlevel configuration and make sure all the services are started at boot-time.
Also start them now.
Stored e-mails should no be delivered and correctly handled by the mail server.
Test all the virtual apache servers, webmail, subversion and WebDAV.
