docker安装运行状态检查

在CentOS系统中，可以通过以下几种方法来检查Docker是否已安装：

1、查看已安装的软件包

[root@iZ2ze1zm9ko9ovzmam7j8oZ ~]# rpm -qa | grep docker

docker-compose-plugin-2.27.0-1.el8.x86_64

docker-buildx-plugin-0.14.0-1.el8.x86_64

docker-ce-cli-26.1.3-1.el8.x86_64

docker-ce-26.1.3-1.el8.x86_64

docker-ce-rootless-extras-26.1.3-1.el8.x86_64

 2、检查docker服务状态

[root@iZ2ze1zm9ko9ovzmam7j8oZ ~]# systemctl status docker
