mysql5.7.x 安裝完成后會(huì)初始化一個(gè) root 用戶(hù)的隨機(jī)密碼，在 /var/log/mysqld.log 日志中可以查看到，也可以通過(guò)命令查找
[root@iZ11fek1j6cZ lib]# grep 'temporary password' /var/log/mysqld.log
2016-11-19T09:43:01.644617Z 1 [Note] A temporary password is generated for root@localhost: LibldhWL+9Fd
#修改密碼
ALTER USER USER() IDENTIFIED BY 'xxxxxxx';
#重啟 MySQL 服務(wù)
service mysql restart
#安裝配置
[root@iZ11fek1j6cZ lib]# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n
... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!
