Mailman3 Easy Installation

I made script to make mailman3 installation easy (automated) based on my experience installing it manually.  for installation guide and prerequisite condition you can see in it’s repository here https://github.com/iomarmochtar/mailman3_ei

Here’s the post installation topics that may you need:

Centos 6 Base Repo

Sometime i need this repo file configuration to install some packages that doesn’t exist in RHEL-like distros,

Propagate cluster.conf to all nodes

It would be easier when we want to change some cluster configuration (/etc/cluster/cluster.conf) using Luci, more over for propagate cluster.conf to all nodes, but sometime i’am often in condition cannot install the package or has a limited access to active it due corporate policy.

So the alternative solution beside send configuration through scp is by using cman_tool, first of all change cluster configuration by increase it by 1, Example:

from

<?xml version="1.0"?>
<cluster config_version="9" name="DB_CLUST">

....

to

<?xml version="1.0"?>
<cluster config_version="10" name="DB_CLUST">
....

then run cman_tool for propagating to all nodes

cman_tool version -r
