Mysql_safe –user=mysql
查看日志报错：var/log/mysqld.log
执行：
./mysqld --defaults-file=/etc/my.cnf --user=mysql
修改server-key.pem权限为777，执行不报错
Kill 进程后通过mysqld_safe 启动
./mysqld_safe --user=mysql&
查看进程，已启动
用root登录，输入临时密码
./mysql --user=root –p
[root@SD-YTHLbpmceshiA0110141443 bin]# find / -name 'mysql.sock';
/var/lib/mysql/mysql.sock
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
再次登录：
./mysql --user=root –p
Ok
set password=password('mysql'); -----括号中为新密码
grant all privileges on *.* to root@localhost;
mysql> flush privileges;
