docker安装启动问题解决排查

一、安装docker报错

刚开始安装docker报这个错：

Error: Transaction test error:

file /usr/libexec/docker/cli-plugins/docker-buildx from install of docker-ce-cli-1:20.10.8-3.el8.x86_64 conflicts with file from package docker-buildx-plugin-0:0.14.0-1.el8.x86_64

根据错误显示发现插件冲突了，删除插件

yum remove docker-buildx-plugin-0:0.14.0-1.el8.x86_64

结果如下：

再次安装

yum install docker-ce-20.10.8-3.el8 docker-ce-cli-20.10.8-3.el8

 显示成功

但是无法启动

二、启动问题

使用命令启动结果报错

sudo systemctl start docker

 查看状态和错误

 但看状态无法发现是什么原因，去查看具体原因

journalctl -u docker.service

 结果如下：

根据这个报错failed to start daemon: failed to dial "/run/containerd/containerd.sock"去查看，以为是没启动，结果查看是启动的

systemctl status containerd

 查看结果如下：

 去查看containerd.sock相关权限

执行下列操作：

sudo chown root:docker /run/containerd/containerd.sock

 然后直接重启

systemctl restart containerd

结果还是一样：

最后发现需要先停止在重启才能奏效

[root@node2 ~]# systemctl stop containerd
[root@node2 ~]# systemctl start containerd
[root@node2 ~]# systemctl start docker.service

 此时查看docker状态已经running了
