2017-08-13T05:03:08.098358Z 1 [Note] A temporary password is generated for root@localhost: NMo*AwW231*A
初始化mysql

# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:        <--输入刚刚上面查找出的mysql的root密码
Re-enter new password:             <--重新设置mysql的root密码。5.7版本的mysql,密码需要设置复杂一点,例如JIK$23#@%trFKN
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) :    <--直接回车
 ... 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) : y
Success.
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!

将mysql设置开机自启动

# chkconfig mysqld on

尝试登录mysql

# mysql -uroot -p
