I am trying to install mySQL server on CentOS6.6 without root access.
But there is an Error message while accessing MySQL database:

How to repeat:
1. Unpack mysql-5.7.13-linux-glibc2.5-x86_64 in a directory(EX:[Base MySQL Directory])
2. Initialize and generate root password: ./mysqld --initialize --user=mysql --lc_messages_dir=[Base MySQL Directory]/share --basedir=[Base MySQL Directory] --datadir=[BaseMySQL Directory]/data --log-error=[Base MySQL Directory]/data/mysql.err --pid-file=[Base MySQL Directory]/mysql.pid --socket=[Base MySQL Directory]/thesock --port=3306 &
3. Start the server: ./mysqld --user=mysql --basedir=[Base MySQL Directory] --lc_messages_dir=[Base MySQL Directory]/share --datadir=[Base MySQL Directory]/data --log-error=[Base MySQL Directory]/data/mysql.err --pid-file=[Base MySQL Directory]/mysql.pid --socket=[Base MySQL Directory]/thesock --port=3306 &
4. Access MySQL database: ./mysql --socket=$MYSQL_TED_HOME/thesock --user=root --password="IL-Rp=Wj*3dg"
