System requirements
Server requirements
Third-party software and repositories
Use an "empty" server: a server with only the operating system installed, without any additional services configured or third-party repositories connected. All necessary repositories will be connected automatically during the ispmanager installation.
Virtualization
We recommend using a fault-tolerant dedicated or virtual server based on hypervisor virtualization.
Resources
We recommend allocating all the disk space to the root file system.
Keep in mind that most of the server resources are consumed by the sites and databases hosted on it.
| Requirements for the control panel | Requirements for the control panel + up to 10 websites | Requirements for the control panel + more than 10 websites | |
|---|---|---|---|
| CPU | 1 core | 1 core | 2 core or more |
| RAM | 1 Gb | 2 Gb or more | 3 Gb or more |
| Disk space | 10 Gb | 20 Gb or more | 50 Gb or more |
We recommend having at least 4 Gb of RAM to ensure efficient operation of ispmanager:
- when using alternative database versions on a server with ispmanager
- when selecting MySQL as the database for the panel data
Supported operating systems
Use the server version of an operating system with the x64 architecture. Desktop versions of operating systems are not supported.
We recommend installing the panel on the server with the latest minor version of the operating system.
Ispmanager does not support updating the server operating system with a change in the major version. Therefore, we recommend choosing an operating system from the list below before installing the panel based on personal preferences and the expected lifespan of the operating system:
- AlmaLinux 8, 9
- Debian 11, 12
- Ubuntu 22.04, 24.04 (recommended)
- Rocky Linux 8
Converting to CloudLinux OS is possible after panel installation.
Network requirements
IP address
The server with ispmanager must use a static IP address specified in the network interface configuration file. If the IP address is assigned to the server using DHCP, correct operation of ispmanager is not guaranteed.
Both IPv4 and IPv6 addresses are allowed.
Firewall
Open the following ports to allow incoming and outgoing connections:
- 21/tcp — to exchange data via FTP protocol
- 22/tcp — for remote access to the server via 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 — for accessing the ispmanager interface and license operation
Port 1500 plays a key role in license-related mechanisms.
- 1501/tcp — for operation of external applications via SSL
- 53/tcp, 53/udp — for domain name servers
- 3306/tcp — for remote access to the database server
To ensure uninterrupted access to license servers, make sure the following server addresses are available at all times:
- 146.0.72.149
- 176.123.174.13
- 89.108.121.204
- 2a05:b40:0:728::2
- 2a03:4900:fffc::401
Supported browsers
The ispmanager web interface is supported in the following browsers:
| Browsers | Minimum version |
| Mozilla Firefox | 70 |
| Google Chrome | 60 |
| Microsoft Edge | 80 |
| Safari | 12 |
| Opera | 47 |
| Yandex Browser | 17.9 |
Using other browsers is also possible, however some functions of the panel's web interface may not work correctly.
