Starting MySQL.. ERROR! The server quit without updating PID file (/data/mysql/26765574162f.pid).
查看报错日志：
[ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
解决办法：
1.编辑配置文件：
vim /etc/my.cnf
basedir = /usr/local/mysql datadir = /data/mysql socket = /tmp/mysql.sock log-error = /data/mysql/error.log pid-file = /data/mysql/mysql.pid user = mysql tmpdir = /tmp
2.重新初始化mysql:
./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql --pid-file=/data/mysql/mysql.pid --tmpdir=/tmp
然后再启动就会成功了：
Mysql启报错报The server quit without updating PID file
