Centos7 rpm方式安装Percona Mysql 8

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

error: Failed dependencies:

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
