Permanently resolve Unix Socket permissions issues after system restart
Every time you restart the system, you need to manually execute sudo chown test:test php7.0-fpm.sock to adjust Unix Socket permissions? This is really annoying. This article provides several methods to automatically set the correct permissions after the system restarts without manual intervention.
First, we need to clarify the creator of the php7.0-fpm.sock file and the user running the file. Typically, the file is created by the PHP-FPM service, whose users are usually www-data or other similar users. The reason for modifying file ownership is usually that other applications need to access the socket. A better solution is to run these applications directly with users with the appropriate permissions.
The following methods can solve this problem:
Method 1: Modify the PHP-FPM configuration file
This is the most recommended method. Directly modify the PHP-FPM configuration file and let the PHP-FPM service start as the target user.
Find the configuration file: The PHP-FPM configuration file is usually located in
/etc/php/7.0/fpm/pool.d/www.conf(the version number may be different, please adjust it according to the actual situation).-
Modify
userandgroupparameters: finduserandgroupparameters and change their values ??totest:<code>user = test group = test</code>
-
Restart PHP-FPM service: apply changes, restart PHP-FPM service:
sudo systemctl restart php7.0-fpm # or use service php7.0-fpm restart
Method 2: Use system service to start the script
If the PHP-FPM configuration file cannot be modified, you can use the system service startup script. This requires caution, and misconfiguration can lead to system instability.
-
Create a startup script: Create a script file, such as
/etc/systemd/system/set-php-fpm-socket-permissions.service(or other suitable path and file name), with the following content:[Unit] Description=Set permissions for php7.0-fpm.sock After=php7.0-fpm.service [Service] Type=oneshot ExecStart=/bin/chown test:test /path/to/php7.0-fpm.sock # Replace /path/to/ with the actual path RemainAfterExit=yes [Install] WantedBy=multi-user.target
-
Enable and start the service:
sudo systemctl enable set-php-fpm-socket-permissions.service sudo systemctl start set-php-fpm-socket-permissions.service
Method 3: Use rc.local (not recommended)
The /etc/rc.local method is outdated and deprecated because it has been deprecated in many modern Linux distributions.
Choose the best method for your system and environment. Method 1 (modify the PHP-FPM configuration file) is the simplest and safest choice. Method 2 (using systemd service) is more suitable for situations where PHP-FPM configuration files cannot be modified, but you need to have a certain understanding of systemd. Remember to replace /path/to/php7.0-fpm.sock to the actual path of the php7.0-fpm.sock file. After restarting the system, verify that the permissions are set correctly.

Why does Binance account registration fail? Causes and solutions
Jul 31, 2025 pm 07:09 PM
