mailman cgi error after server restart
Hi guys,
My server is Red Hat Enterprise Linux ES release 4. I installed mailman 2.1.3 and postfix. It has worked for 4 years. Yesterday I restarted the server, but found I can not go to thehttp://MyDomain/mailman/create <http://mydomain/mailman/create> page. It shows the following error:
Mailman CGI error!!!
The Mailman CGI wrapper encountered a fatal error. This entry is being stored in your syslog:
Group mismatch error. Mailman expected the CGI wrapper script to be executed as group "daemon", but the system's web server executed the CGI script as group "apache". Try tweaking the web server to run the script as group "daemon", or re-run configure, providing the command line option `--with-cgi-gid=apache'.
it says I could re-run configure, but I have run this about 4 years and have many mail list. If I re-run configure, will I lose some data?
How to run the postfix as group "daemon"?

Your version of Mailman is almost 10 years old. I'd be inclined to upgrade that.

check_perms is the (Mailman) script you want.

Running configure, make and make install will not result in data loss, but you should stop Mailman before make install and start it after.
If you have local mods to the Mailman code or you made settings in Defaults.py instead of mm_cfg.py, there can be loss of those things, so make your settings in mm_cfg.py and if you have modes to running code, be sure you know what they are so you can reapply them.

Postfix is not the issue in your original post. Your OP referred to a CGI wrapper group mismatch, not a mail wrapper group mismatch.
You can set the group in Apache with Apache's Group directive, but this is a global setting. In Apache 2.4, there is also a VHostGroup directive that applies only to a VirtualHost, but not in older versions. See <http://httpd.apache.org/docs/>.
For Postfix, if delivery is via aliases, postfix will run the pipe in a Mailman alias as the user and group of the owner of the aliases.db file in which the alias is found. Note this is the primary group of the owner of the file, not the group of the file.
