3.安装mysql-server

[root@nmb1 ~]# rpm -ivh mysql-community-server-5.7.17-1.el6.x86_64.rpm

4.启动mysqld

[root@nmb1 ~]# service mysqld start
初始化 MySQL 数据库：                                      [确定]
Installing validate password plugin:                       [确定]
正在启动 mysqld：                                          [确定]

5.查看mysql 5.7安装时的初始化密码

[root@nmb1 ~]# grep 'temporary password' /var/log/mysqld.log
2017-03-26T22:05:05.842897Z 1 [Note] A temporary password is generated for root@localhost: lo!lbrLjk9r7

6.更改初始化密码

[root@nmb1 ~]# mysql -uroot -p'lo!lbrLjk9r7'
mysql: [Warning] Using a password on the command line interface can be insecure.

注：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误。如想更改密码策略请链接至：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements。
