ALTERNATIVE PLATFORMS
Installing Lotus Domino on Linux
By Allan Liska and Jeff Gunther
Last month, we tried to make a business case for deploying Domino for Linux within a small to mid-sized enterprise. We hope that this issue will provide you a detailed installation tutorial on getting Domino up and running under Linux. In order to make the article manageable, we had to make some assumptions about your environment and your expertise with operating systems, in particular, Red Hat 6.2 and Domino. If you need any instructions on setting up a Linux environment, there are many great resources online. You can find our recommendations in the product availability section at the end of this article.
System requirements
In order to install Domino R5 under Linux, the following minimum requirements must be met:
- 486 processor or later;
- 64MB RAM or larger (128MB is recommended);
- Swap file of two times the physical RAM or greater;
- 750MB free space hard drive space or larger;
- Linux kernel version 2.2.5. This installation has been certified on Red Hat 6.0 and above.
Installing Red Hat 6.2
Before installing Domino, the Linux environment needs to be installed and configured. The good news is that Red Hat is very straightforward to install. Just follow these steps:
- Obtain Red Hat 6.2. Every version of Red Hat provides different features and levels of support. For our installations, we used the standard version;
- Boot from CD. If your system doesn't provide this support, boot from the floppy disk provided by Red Hat;
- Use the "Server" installation. Red Hat provides different customized installations of Linux. Simply follow the steps throughout the installer.
System preparation
Before getting started with Domino installation, a few tasks must be completed. These tasks include shutting down both the SendMail SMTP (Simple Mail Transfer Protocol) Server and the Apache Web Server.
Disable SendMail
Since Domino provides its own set of SMTP services, we need to disable the standard SendMail service within Linux. First, log in to your system as "root." In order to stop SendMail, type the command:
/etc/rc.d/init.d/sendmail stop
|
This will disable the SendMail server. Note that this doesn't uninstall the program; it will only shut it down. The next step is to keep it from running automatically after the system reboots. Open the file /etc/rc.d/init.d/sendmail in your favorite editor. Then find the lines:
echo -n "Starting sendmail:"
daemon /usr/sbin/sendmail -bd -qlh
echo
touch /var/lock/subsys/sendmail
; ;
