    but after restart mysql
    server.pid deleted and ERROR! The server quit without updating PID file (/var/lib/mysql/server.pid).

    Did you checked mysql error log ? It will provide more details what causing it. Can you please show relevant error log entries for that from /var/lib/mysql/server-error.log file.
