版本：社区版 5.7.11
1.采用mysqld --initialize的方式安装数据库
[mysql@host02 bin]$ ./mysqld --initialize --user=mysql--basedir=/db/mysqlmha --datadir=/db/mysqlmha/data

2.使用初始化密码登陆mysql
./mysql -h localhost uroot -p -S /db/mysqlmha/data/mysql.sock
mysql> show databases;
ERROR 1820 (HY000): Unknown error 1820
mysql> set password=password('mysql');
Query OK, 0 rows affected, 1 warning (0.03 sec)


解决办法就是登陆进去后里面采用set password 的方式修改密码。
