Symptoms:
Upon rebooting servers running AlmaLinux, CloudLinux, or Rocky 8 after cPanel installation, users experience inaccessibility.
Description:
The installation of cPanel on AlmaLinux/CloudLinux/Rocky 8 servers disables the NetworkManager service, replacing it with the Network service. Customizations to network-related configurations may conflict with this change, preventing the Network service from starting during server boot. Consequently, servers become inaccessible upon reboot.
Workaround:
To resolve this issue, collaborate with the network or system administrator to ensure server compatibility with the Network service. The problem primarily arises if customizations have been made to the stock images of these operating systems. In certain cases, seeking assistance from the hosting provider may be necessary. As a general workaround, re-enable NetworkManager before rebooting the server after cPanel installation.
Steps:
1. Install cPanel.
2. Re-enable NetworkManager using commands like the following if access to SSH/Terminal/Console is available:
- /usr/bin/systemctl disable network
- /usr/bin/systemctl enable NetworkManager
- /usr/bin/systemctl stop network; /usr/bin/systemctl start NetworkManager
3. Reboot the server.
