======i-MSCP Requirements======

=====General=====

  * 1 GHz or faster 32 bits (x86) or 64 bits (x64) processor (recommended)
  * 1 Gio memory (minimum) - For heavily loaded servers or high flow is recommended at least 16 Gio
- 2 Gio of available hard disk space for i-MSCP and managed services, excluding user data
  * Internet access (100 Mbits/s recommended)
  * A file system that supports extended attributes such as ext2, ext3, ext4 or reiserfs*.

* In case of reiserfs, you must ensure that your file system is mounted with the **attrs** option. See [[start:howto:reiserfs|Using reiserfs file system with i-MSCP]] for more information.

=====Distribution=====

  * Debian >= Wheezy (Base system with standard packages installed)
  * Ubuntu >= Precise Pangolin (Base system with standard packages installed)

=====Software Version=====

  * PHP >= 5.3.2
  * Perl >= 5.14.2

=====Note for Proxmox/Docker/LXC users=====

If you want install i-MSCP inside a LXC container, the following conditions must be met:
 
  - You must have the ''CAP_MKNOD'' capability inside the container. Thus, you must ensure that `mknod` is not in the list of dropped capabilities (needed for pbuilder).
  - You must have the ''CAP_SYS_ADMIN'' capability inside the container (needed for mount(8)). Thus, you must ensure that `sys_admin` is not in the list of dropped capabilities.
  - You must allow the creation of devices inside the container by white-listing them (needed for pbuilder). Easy solution is to add ''lxc.cgroup.devices.allow = a *:* rwm'' in LXC container configuration file.
  - If you use ''Apparmor'', you must allow bindmounts inside your container by modifying the default apparmor profile ''/etc/apparmor.d/lxc/lxc-default'' or by creating a specific apparmor profile for the container.

Note that all those operations must be done on the host, not in the container.
