查看临时密码
grep 'temporary password' /data/log/mysql-error.log
脚本拷贝
1 [root@redis02 support-files]# ls 2 magic mysqld_multi.server mysql-log-rotate mysql.server 3 [root@redis02 support-files]# cp mysql.server /etc/init.d/mysqld
chmod mysql:mysql /etc/init.d/mysqld
重启mysql
/etc/init.d/mysqld restart
做测试时basedir 和 datadir概念没搞明白浪费很长时间
