We recommend that you install a control panel on a fault-tolerant virtual or dedicated server that supports hypervisor virtualization or OVZ container virtualization.
Websites hosted on a server consumes the most part of its resources. Please note that websites with databases and mailboxes consume more server resources.
|Component||Requirements for the control panel||Requirements for the control panel and up to 100 sites||Requirements for the control panel and more than 100 sites|
|CPU||1 GHz||2.4 GHz||from 3 GHz|
|RAM||4 Gb||16 Gb||from 24 Gb|
|Disk space||60 Gb||120 Gb||from 200 Gb|
Allocate all available disk space for the root filesystem.
You may change the partition if needed. Please note that ispmanager by default locates user data into /var/www (user disk quotas are set on the partition where user data are located), and the control panel is installed into /usr/local/mgr5/.
Supported operating systems (amd64)
- AlmaLinux 8 (recommended);
- CentOS 7;
- CloudLinux OS SHARED — installation is available only through the integration module.
We strongly recommend a clean install of ISPmanager. You should install a minimal version of the operating system, all the services that ISPmanager requires will be installed automatically during software installation.
Open the following ports to allow incoming and outgoing connections:
- 20/tcp — to send data through FTP;
- 22/tcp — for remote access to a server through SSH;
- 110, 143, 993, 995, 587, 465, 25/tcp — to send and receive emails;
- 80, 443/tcp — to handle user requests to websites on the server with ISPmanager;
- 1500/tcp —to access the ISPmanager interface;
- 53/tcp, 53/udp — for domain name servers;
- 3306/tcp — for the database server.
When configuring the network between cluster nodes please note that:
- cluster nodes must locate in the same data-center;
- use two physical network interfaces on every cluster node. Connect the first interface in a public network, the second interface should be connected to an internal one with cluster nodes only.
This will enhance cluster reliability and avoid network issues during migration.
