1. 下载安装包
Percona Mysql安装包下载地址：https://www.percona.com/downloads/Percona-Server-LATEST
下载以下四个安装包：
percona-server-client-8.0.17-8.1.el7.x86_64.rpm
percona-server-server-8.0.17-8.1.el7.x86_64.rpm
percona-server-shared-8.0.17-8.1.el7.x86_64.rpm
percona-server-shared-compat-8.0.17-8.1.el7.x86_64.rpm
2. 安装
安装时报错：
rpm -ivh percona-server-shared-compat-8.0.17-8.1.el7.x86_64.rpm
warning: percona-server-shared-compat-8.0.17-8.1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 8507efa5: NOKEY
error: Failed dependencies:
mariadb-libs is obsoleted by percona-server-shared-compat-8.0.17-8.1.el7.x86_64
因为安装了mariadb-libs，需要先删除：
yum remove mariadb*
rpm -ivh percona-server-shared-8.0.17-8.1.el7.x86_64.rpm
rpm -ivh percona-server-client-8.0.17-8.1.el7.x86_64.rpm
rpm -ivh percona-server-server-8.0.17-8.1.el7.x86_64.rpm
需要先安装依赖包：yum install numactl，如果不安装报错如下：
rpm -ivh percona-server-server-8.0.17-8.1.el7.x86_64.rpm
warning: percona-server-server-8.0.17-8.1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 8507efa5: NOKEY

3. 启动mysql
service mysql start
ps -ef |grep mysql
service mysql status
4. 登录mysql
Percona Mysql 默认密码：
cat /var/log/mysqld.log |grep "temporary password"
[Note] [MY-010454] [Server] A temporary password is generated for root@localhost:
登录时需对密码特殊字符转义：
mysql -uroot -p\
登录后需重置密码：
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
alter user user() identified by 'password';
密码需符合密码规则，否则重置密码失败：
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
