If you purchase the license from the cPanel Store, you will automatically receive an IP address-based license. We grant this license based on the static IP address at which you installed the operating system (OS). If you purchase an IP address-based CloudLinux license, the cPanel & WHM installation process automatically installs CloudLinux. cPanel, Inc.
Does not support the use of Xen paravirtualization (Xen PV) with CloudLinux. To install CloudLinux from an ISO, perform the following steps:.
Download the that matches your server's architecture. We only support Amazon Linux on the official cPanel & WHM AMI. To find this AMI, navigate to the download in the AWS™ marketplace. We strongly recommend that you do not install cPanel & WHM on servers that rely on snapshot data (for example, Amazon EC2™ Spot Instances).
When these servers revert to use snapshot data, the system detects this action as a uniqueness change. This behavior causes these servers' cPanel & WHM licenses to lock due to the uniqueness changes for that server's cPanel & WHM license. A locked license disables a cPanel & WHM server.
Operating state In Linux, the operating system possesses several levels of operating states. Each different level represents a system configuration and allows users to access different processes. Systemctl set-default TARGET.target For a complete list of targets, visit 's article Disable SELinux If your server runs an operating system from a source other than the, you must disable SELinux to make your system compatible with cPanel & WHM.
To disable SELinux security features, use one of the following methods:. Use the graphical interface to disable SELinux while you configure your operating system, and then reboot the server. Edit the /etc/selinux/config file to set the SELINUX parameter to disabled, and then reboot the server. To run cPanel & WHM on your server, SELinux must remain disabled. SELinux in enforcing mode does not allow cPanel & WHM to function properly. For more information about SELinux modes, read the documentation. While cPanel & WHM can function with SELinux in permissive mode, we recommend that you do not use it.
Permissive mode generates a large number of log entries. To check the status of SELinux on your server, run the sestatus command. Do not transfer the SELinux configuration file between computers. It may destroy the file's integrity.
Perl installation Perl must exist on your server before the installation script for cPanel & WHM can run successfully. If Perl does not exist during installation, the cPanel & WHM installer attempts to install Perl via the yum -y install perl command.
If you see errors during this step of the installation process, read our documentation. For more information about Perl on your server, and which versions of Perl ship with specific operating systems, read our documentation. CPanel & WHM servers use multiple Perl environments. Additional partitions improve performance for some servers, especially servers with high email volume. The OS can only access a limited number of files per partition.
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. Virtual environments cPanel products support the following virtual environments. If you use a Linux bridge on a KVM server, you may experience problems with multicast routing. These problems affect the server's ability to resolve nodes on the network. For example, IPv6 Stateless Address Autoconfiguration (SLAAC) addresses may drop off intermittently, or the server may experience problems when it attempts to find the router. To resolve this issue, set the multicastrouter system knob value to 2.

In this article I'm going to review connecting to your cPanel account's various services, when there is a firewall on your computer or router not allowing a normal connection over the standard ports. There are several default services that come with your hosting account, these operate over a different port than the standard port 80 that normal website traffic is relayed over. In some cases these additional ports are blocked from being accessed by your local computer or router's firewall settings, this is especially very common if you're in an office environment where you don't control the firewall settings. Below I'll go over the default ports used to access, and (Web Host Manager), and then I'll also cover the proxy subdomains that you can use to access these services when your firewall is blocking their normal ports. CPanel proxy subdomains The following table shows the standard port that the various cPanel services operate under, as well as the secure port that they can use when accessing it over an SSL encrypted connection.
The proxy subdomain for each service will be a URL you can use to access the particular service over the standard port 80 that should be open in your firewall if you're having issues accessing it otherwise. Be sure to replace example.com with your own domain name when using any of the cPanel proxies. Service Standard port Secure port Proxy subdomain cPanel 2082 2083 cpanel.example.com Webmail 2095 2096 webmail.example.com WHM (Only on VPS and dedicated servers) 2086 2087 whm.example.com You should now understand why you might be having issues trying to connect to various cPanel services with the default ports that they use on the server. Using the cPanel proxy domain examples you should be able to still access the particular service even behind a firewall that is blocking the standard ports.
I found this solution somewhere on the internet. This issue is caused due to expired cpanel license or the corrupted license file.
It can be resolved by moving /var/cpanel/updateblocks.config and resynchronizing the cPanel license with /usr/local/cpanel/cpkeyclt. # mv /var/cpanel/updateblocks.config /var/cpanel/updateblocks.config.bk # /usr/local/cpanel/cpkeyclt If its still the same, try to disable the CSF firewall by # csf -x and then resynchronizing the cPanel license. Unfortunately I receive this error.
