4.启动、停止服务
CentOS 6:
service mysqld start
service mysqld restart
## ...
CentOS 7:
systemctl start mysqld.service
systemctl restart mysqld.service
## ...
## 添加开机启动
systemctl enable mysqld.service
5.卸载
# 停止服务
service mysqld stop
##or
systemctl stop mysqld.service

yum remove Percona-Server*
# 删除数据目录和配置文件
rm -rf /var/lib/mysql

6.修改 Percona 默认密码
修改方法与 mysql 5.7 配置一样，运行mysql_secure_installation命令，根据提示操作即可。
默认密码在错误日志中，错误日志位置可以在/etc/my.cnf文件中找到(log-error)，一般是/var/log/mysqld.log，可以通过以下命令快捷找到：
cat /var/log/mysqld.log | grep "temporary password"
