We recommend the following configuration settings when you install cPanel & WHM.
When you install your operating system (OS), we recommend that you use the following filesystems:
Chinese
Englishext4 filesystems.All other supported operating systems — Use an ext filesystem (ext3 or ext4).
Warning:
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.
| Partition | Size |
|---|---|
/ |
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.
|
CentOS 5 |
|
| RAM | Minimum 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 |
|
| RAM | Minimum 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 |
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.
