Configuration

Back

Overview

We recommend the following configuration settings when you install cPanel & WHM.

Recommended filesystem

When you install your operating system (OS), we recommend that you use the following filesystems:

  • CentOS 7 — Use the XFS® or ext4 filesystems.
  • All other supported operating systems — Use an ext filesystem (ext3 or ext4).

Warning:

If you use the ext4 filesystem on RHEL 5 or CentOS 5, you must download and install the e4fsprogs package in the Red Hat documentation.

Remember:

We only develop and test cPanel & WHM on filesystems that support flock. Some network filesystems (for example, NFS) may require additional configuration in order to function properly.

Recommended partitions 

PartitionSize
/

Grow to fill disk (40 Gigabytes (GB) recommended, 20 GB minimum).

Note:

To host a greater number of accounts, allocate more disk space to this partition.
swap See the Recommended swap space section below.

Note:

For some servers, additional partitions are beneficial. This is particularly true for servers with high email volume. The OS can only access a limited number of files per partition.

Recommended swap space

CentOS 5

RAMMinimum swap space
4 GB or less 2 GB
4 GB to 16 GB 4 GB
16 GB to 64 GB 8 GB
64 GB to 256 GB 16 GB
256 GB to 512 GB 32 GB

 

 

 

CentOS 6 and 7

RAMMinimum swap space
2 GB or less Two times the amount of RAM on the server.
2 GB to 8 GB The same as the amount of RAM on the server.
8 GB to 64 GB Half the amount of RAM on the server.
64 GB or more 4 GB

 

 

 

 

iNodes

In Linux, an inode is a filesystem object that contains the owner, permissions, and other important metadata. Every file, image, directory, email, and symbolic link on your server requires an inode.

  • On average, files on webservers are usually smaller than on other types of servers. Therefore, we recommend that you allocate more than the default number of inodes on your server's partitions.
  • If you install everything on a single partition, the base cPanel & WHM or cPanel DNSONLY installation requires at least 1,000,000 inodes, plus at least 50,000 inodes per cPanel account that you plan to host.
