CentOS 7.2 安装配置 Percona Server

个人比较喜欢 MySQL 的轻量，今天花了一点时间把云服务上的 MySQL5.7 换成了 Percona-Server ,Percona 是一个开源的 MySQL 衍生版。InnoDB的数据库引擎使得 Percona 服务器非常有吸引力，如果你需要的高性能，高可靠性和高性价比的解决方案，它将是一个很好的选择。
安装
#安装 YUM 源
yum install http://www.percona.com/downloads/percona-release/RedHat/0.1-3/percona-release-0.1-3.noarch.rpm
#测试 YUM 源是否生效
yum list | grep percona
#安装 Percona-Server
yum install Percona-Server-server-57 Percona-Server-client-57
#启动服务
service mysqld start
#登录 MySQL
mysql -u root -p

mysql5.7.x 安装完成后会初始化一个 root 用户的随机密码，在 /var/log/mysqld.log 日志中可以查看到，也可以通过命令查找

[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
#修改密码
ALTER USER USER（） IDENTIFIED BY "xxxxxxx";
#重启 MySQL 服务
service mysql restart
#安装配置
[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！
