The Proxmox Mail Gateway 2.1 template is an OpenVZ OS template that allows you to run the Antispam & Antivirus Mail Gateway. Proxmox runs in different virtualization environments but in OpenVZ it is almost twice as fast as with full virtualization - due to the minimal overhead. Proxmox offers free and commercial licenses.
== Prerequisites ==I assume you have already a running OpenVZ server. This HowTo is based on an fresh Centos 4.4 installation with OpenVZ kernel 2.6.9 but should also work also with all other combinations. I used a Dual Xeon with 2 GB Ram.
== Installation ==Download the Proxmox OpenVZ template:
<pre>wget http://www.proxmox.com/cms_proxmox/cms/upload/bittorrent/debian-4.0-proxmox-mailgateway-2.1.tar.gz</pre>
Copy the template into the template cache, usually to /vz/templates/cache/
== Create a default config ==
Create a reasonable default config if you don’t have one. The following command creates the file /etc/vz/conf/ve-default.conf-sample which contains reasonable defaults if you plan to run 5 VEs:
<pre>vzsplit -n 5 -f default</pre>
== Create the VPS a VE == Choose a free VE ID, we use 777 for this guide.
<pre>vzctl create 777 --ostemplate debian-4.0-proxmox-mailgateway-2.1 --config default</pre>
== Configure the VPS VE ==
Set IP Address and DNS nameservers, start servers automatically at boot time: please adapt these settings to your environment.
<pre>vzctl set 777 --vmguarpages 512M:2147483647 --privvmpages 1G:1100M --diskspace 4000M:4400M --save</pre>
== Start the VPS VE ==
<pre>vzctl start 777</pre>
[root@vz1 ~]#</pre>
== Backup considerations, live migration, and HA Cluster ==
The Proxmox HA Cluster consists of a master and several nodes (minimum one node) - All can be run on different OpenVZ servers within the same subnet. Configuration is done on the master, all configuration and data is synchronized to all cluster nodes over a VPN tunnel.
For online backups: , see [[Backup_of_a_running_VE_with_vzdump]]
Live migration: see [[Checkpointing_and_live_migration]]
For HA Cluster: , see http://www.proxmox.com/cms_proxmox/en/technology/proxmox-ha-cluster/
== Proxmox configuration ==
For the Proxmox configuration point your web browser to the given IP address.
