This section shows a method to check the systems by using the Typical LifeKeeper Postfix Environment 1 as an example before you start to create resources in LifeKeeper.
Postfix Configuration Validation Steps
- Postfix Configuration
The Postfix configuration files are on both servers.
- Bring up virtual IP address for SMTP
You must bring up virtual IP address for SMTP. You can configure it by using the “ifconfig” command or creating a LifeKeeper IP resource.
- Mount the shared filesystem for queue area
- Mount the shared filesystem for spool area
- Start Postfix
- Verify processes and socket for Postfix
- Stop Postfix
If you cannot start or stop Postfix in steps 5-7, please check the Postfix error messages. Once there are no error messages in the log file, the configuration is correct. Next, repeat steps 1-7 on all systems in the cluster and confirm that the configuration is correct.
