一、yum安装
1.安装Percona yum存储库

yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm

2.启用Percona Server 8.0存储库

percona-release setup ps57

3.输出如下则安装成功

[root@localhost ~]# percona-release setup ps80
* Disabling all Percona Repositories
* Enabling the Percona Server 8.0 repository
* Enabling the Percona Tools repository
<*> All done!

4.yum list查看安装的储存包

yum list | grep percona

5.安装percona-xtrabackup-24

yum -y install percona-xtrabackup-80.x86_64

6.如果报错缺少rpm文件，去官网下载

yum -y install mysql-community-libs-compat.x86_64
