Apr 01, 2025 am 07:12 AMThe solution to automatically set Unix Socket permissions after system restart
In Unix systems, socket file permissions are often needed. For example, after restarting sudo chown test:test php7.0-fpm.sock
needs to modify php7.0-fpm.sock
permissions, which is time-consuming and error-prone. This article provides several solutions to this problem permanently.
First, determine the creator (usually the php-fpm service) of php7.0-fpm.sock
and its running users and groups (e.g. www-data
). The reason for modifying ownership is usually that other programs need to access the socket file. Ideally, the program run user should be adjusted instead of repeatedly modifying socket permissions.
The following methods can avoid manually setting permissions:
-
Modify the php-fpm configuration file: In the php-fpm configuration file (for example,
www.conf
), findlisten.owner
andlisten.group
parameters and set them as the target user and group. For example:<code> listen.owner = test listen.group = test</code>
Restart the php-fpm service to make the configuration take effect.
-
Use systemd service management: Use systemd service management tool to add
ExecStartPost
directive to the service file, and automatically execute the permission setting command after the service is started. For example:<code> [Service] ExecStartPost=/bin/chown test:test /path/to/php7.0-fpm.sock</code>
/path/to/
is replaced with the actual socket file path. The systemd service needs to be reloaded or restarted to apply the changes. Adjust the program run user: If other programs need to access socket files, modify the run user or group of these programs to be consistent with the owner and group of socket files, and you can avoid permission problems.
Through the above methods, the automated setting of Unix Socket permissions can be achieved, system management efficiency can be improved, and errors caused by manual operations can be avoided. Which method to choose depends on the specific environment and needs.
