Var Lib Php Session Permission Error Nginx
What is the Var Lib Php Session Permission Error Nginx?
The Var Lib Php Session Permission Error Nginx is an error message that appears when a web server does not have the necessary permissions to run a PHP script or web application. This type of error is common when using Nginx as a web server because Nginx does not have the same type of default permissions as other web servers like Apache, and as a result, needs to be tweaked to allow for scripts and applications to run.
The error message itself states “Cannot write session data: Permission denied, open(‘/var/lib/php/session/session.save_path’, O_RDWR) failed: Permission denied (13)”, which means that the web server does not have access to the directory structure in which the script is trying to run. This can occur because the web server does not have the necessary permissions set to allow access to a specific directory or because the web server does not have the ability to set the correct permissions on its own.
How to Fix the Var Lib Php Session Permission Error Nginx
There are a few steps that can be taken in order to fix the Var Lib Php Session Permission Error Nginx. The first step is to make sure that the web server is configured to allow for the script to run. This can be done using a specific configuration file such as the “nginx.conf” file, which will be located in the main installation directory for Nginx.
Inside the “nginx.conf” file, the user can add the following lines of code to allow for the script to run:
location /var/lib/php/session/ {
allow all;
}
This will tell the web server to allow access to the directory that the script is attempting to run on. After making this change, the web server should be restarted in order for the new settings to take effect.
After the web server has been restarted, it is important to double check that the permissions for the directory have been set correctly by running the following command:
ls -l /var/lib/php/session/
If the permissions for the directory have been properly set, the output of this command should display something like this:
drwxrwxr-x 2 user user 4096 Aug 28 14:31 session.save_path
The numbers at the beginning of the output represent the permissions for the directory — in this case, the number is “drwxrwxr-x”, which means that the directory can be read, written to, and executed by users with the appropriate permissions.
How to Change the Permissions for the Directory
If the permissions for the directory are not set correctly, they can be changed using the following command:
chmod -R 755 /var/lib/php/session/
The “-R” flag is used to set the permissions for the entire directory structure recursively, so the command will set the permissions for every file and folder inside the directory. Additionally, the number “755” is used to set the permissions — in this case, the number will set the read, write, and execute permissions to every user with the appropriate permissions.
After the permissions have been changed, it is important to double check that the correct permissions have been set by running the same command used in the step above:
ls -l /var/lib/php/session/
If the correct permissions have been set, the output should look like this:
drwxr-xr-x 2 user user 4096 Aug 28 14:31 session.save_path
What to Do If the Error Persists
If the error persists after following the steps above, it may indicate that another issue is causing the error. In this scenario, it is recommended to check the other configuration files such as the “php.ini” file to make sure that all of the necessary settings are in place.
Conclusion
The Var Lib Php Session Permission Error Nginx can be a tricky error to solve, but with a little bit of knowledge and patience it can be navigated. The steps above should help to fix the issue, but if they do not, it is best to seek the help of an experienced web developer in order to correctly debug and fix the issue.
