open_basedir = .:/tmp/ #Setting means to allow access to the current directory (that is, the directory where the PHP script file is located) and the /tmp/ directory, which can prevent the PHP Trojan from cross-site, if there is a problem with the installation program after the change (for example: weaving dream Management system), you can cancel this line, or write directly into the program directory /data/www.111cn.net/:/tmp/

: wq! #Save and exit

systemctl restart mariadb.service #Restart MariaDB
