找了一晚上了，貌似都没有我这个错嘛？？

[X-i-n]

mysql服务端已经装好了，只是服务没起得来。什么操作系统？/var/lib/mysql/**.err看看有什么内容在里边。

[X-i-n]

还有 /tmp目录应该是777。你的日志里报的错误原因是权限被拒绝，把/tmp权限重置一下，或者重新设置一下tmpdir。

[没头脑992]

系统为CentOS 6.8 64位的
按照你说的路径没找到.err的错误日志..

/tmp的路径是为777的，也重设了一下权限，启动服务还是抛异常：Starting MySQL. ERROR! The server quit without updating PID file (/usr/local/mysql/data/992.pid).

谢谢你，我现在大致有点思路，只好现在再百度下你说的那些问题原因

[没头脑992]

还是没找到错误日志，tmpdir也没找到，明天继续

那应该是你mysql目录权限有问题。

chown -R mysql:mysql /var/lib/mysql
