phpMyAdmin – session_start(): open(SESSION_FILE, O_RDWR) failed: Permission denied (13)

phpMyAdmin – Error

Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.

session_start(): open(SESSION_FILE, O_RDWR) failed: Permission denied (13)

Try to chown /var/lib/php/session/ with the user who is running httpd.
In my case it was nginx.

chown nginx: /var/lib/php/session/

nginx – failed (13: Permission denied)

In a fresh CENTOS, while installing & testing nginx i’v faced the following error..

2019/10/10 17:54:11 [crit] 18960#0: *1 stat() "/home/www/html/index.php" failed (13: Permission denied), client: 94.61.69.69, server: 51.158.69.69, request: "GET /index.php HTTP/1.1", host: "51.158.69.69"

This is how I’v solved.

chcon -R -t httpd_sys_content_t /home/www/html/
