mysql报错

[root@instance-67fp5rsl mysql]# /etc/init.d/mysqld restart
MySQL server PID file could not be found!                  [FAILED]
Starting MySQL.Logging to '/usr/local/mysql/data/instance-67fp5rsl.err'.
..The server quit without updating PID file (/usr/local/mys[FAILED]instance-67fp5rsl.pid).

求高手指点 为什么一直包这个错误? 新安装的mysql数据库总是报错
