MySQL Server依赖MySQL Common、MySQL Libs、MySQL Client，所以先安装mysql-community-common、mysql-community-libs和mysql-community-server。
依次安装mysql-community-common、mysql-community-libs、mysql-community-client、mysql-community-server。

临时密码必须修改，否则会报：ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
grep 'temporary password' /var/log/mysqld.log输出：

The existing password for the user account root has expired. Please set a new password.

Re-enter new password:
... Failed! Error: Your password does not satisfy the current policy requirements
New password:是否删除匿名用户
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) :是否禁用 root 用户远程登录
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) :是否删除 MySQL 用于测试的数据库
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) :是否重新加载权限表
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) :进入 MySQL 命令行
mysql -uroot -p基础配置
Vim下输入:set paste进入粘贴模式，否则可能会出现全是注释。
:set paste!还原为插入模式。
