检查percona-xtrabackup是否已安装？

Question

我在我的OEL 7上安装了percona-xtrabackup，但如何检查它是否已安装

[root@M1 ~]# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@M1 ~]# su - mysql
[mysql] sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
[mysql] sudo percona-release enable-only tools release
[mysql] sudo yum install percona-xtrabackup-80
[mysql] rpm -qa | grep xtrabackup
percona-xtrabackup-80-8.0.7-1.el7.x86_64

Answer 1

您可以使用此命令检查它是否已安装

[root@tester ~]# yum list installed | grep xtrabackup

如果安装了它，它将显示如下：

[root@tester ~]# yum list installed | grep xtrabackup
percona-xtrabackup-24.x86_64               2.4.18-1.el6                 @percona-release-x86_64

或者你可以像下面这样运行这个软件：

[root@tester ~]# xtrabackup --version

如果安装了它，它将显示如下内容：

xtrabackup version 2.4.18 based on MySQL server 5.7.26 Linux (x86_64) (revision id: 29b4ca5)
