mysqld无法启动问题

启动mysql时报错：

141220 07:50:59 mysqld_safe mysqld from pid file /usr/local/mysql/data/vps.cbo999.com.pid ended
141220 07:54:30 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

分析：是/tmp/mysql.sock 不存在

由于mysql 默认的mysql.sock 是在/var/lib/mysql/mysql.sock，创建符号连接：

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
