Centos 7.5 docker 怎么设置开机自启

解决方案：

1.docker 开机自启设置

root@localhost ~]# systemctl enable docker.service
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

2.设置容器开机自启

查看容器

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE                   COMMAND                  CREATED             STATUS                        PORTS                                      NAMES

848a2581da80        mysql:5.7               "docker-entrypoint.s…"   10 days ago         Exited (255) 12 minutes ago   33060/tcp, 0.0.0.0:3307->3306/tcp          mysql

更新容器
docker update --restart=always chemex
docker update --restart=always mysql

[root@localhost ~]# docker update --restart=always chemex       
chemex
[root@localhost ~]# docker update --restart=always mysql
mysql

3.重启服务器或者重启docker测试
