Percona XtraBackup 8.0, 安装与测试  
Percona XtraBackup 8.0 是Percona XtraBackup新推出了一个针对MySQL8.0的版本，主要是MySQL8.0在Redo 和 数据库字典方面有了新的改进。 XtraBackup 2.4 继续支持MySQL 5.6 和 5.7。

（1）移除了innobackupex命令；（2）由于新的MySQL重做日志和数据字典格式，8.0版本只支持mysql8.0和percona8.0；（3）早于mysql8.0的版本需要使用xtrabackup2.4备份和恢复.

step 1 下载

wget [https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-8.0.4/binary/redhat/7/x86\_64/percona-xtrabackup-80-8.0.4-1.el7.x86\_64.rpm][https_www.percona.com_downloads_XtraBackup_Percona-XtraBackup-8.0.4_binary_redhat_7_x86_64_percona-xtrabackup-80-8.0.4-1.el7.x86_64.rpm]

step 2 安装已下载文件

yum localinstall percona-xtrabackup-80-8.0.4-1.el7.x86\_64.rpm

step 3 判断安装是否已安装成功

rpm -qa | grep -i xtrabackup

相关文件查询

rpm -ql percona-xtrabackup-80

xtrabackup安装版本的查询：

xtrabackup --version  
本测试查询后的信息如下：

xtrabackup version 8.0.4 based on MySQL server 8.0.13 Linux (x86\_64) (revision id: c2c0777)

我们应该特别小心，这个xtrabackup version 运行的基础是MySQL server 8.0.13。如果，MySQL的版本是之前的版本，在恢复阶段会报错：

xtrabackup: Error: cannot open file './xtrabackup\_tablespaces'xtrabackup: Error: failed to load tablespaces list.  
It is possible that the backup was created by Percona XtraBackup 2.4 or earlier version. Please use the same XtraBackup version to restore.
