- 下载docker的安装文件
https://download.docker.com/linux/static/stable/x86_64/
下载的是：docker-18.06.3-ce.tgz 这个压缩文件
- 将docker-18.06.3-ce.tgz文件上传到centos7-linux系统上，用ftp工具上传即可
- 解压
| [root@localhost java]# tar -zxvf docker-18.06.3-ce.tgz |
- 将解压出来的docker文件复制到 /usr/bin/ 目录下
| [root@localhost java]# cp docker/* /usr/bin/ |
- 进入/etc/systemd/system/目录,并创建docker.service文件
| [root@localhost java]# cd /etc/systemd/system/ |
| [root@localhost system]# touch docker.service |
- 打开docker.service文件,将以下内容复制
| [root@localhost system]# vi docker.service |
注意： --insecure-registry=192.168.200.128 此处改为你自己服务器ip

- 给docker.service文件添加执行权限
| [root@localhost system]# chmod 777 /etc/systemd/system/docker.service |
- 重新加载配置文件（每次有修改docker.service文件时都要重新加载下）
| [root@localhost system]# systemctl daemon-reload |
- 启动
| [root@localhost system]# systemctl start docker |
- 设置开机启动
| [root@localhost system]# systemctl enable docker.service |
- 查看docker状态
| [root@localhost system]# systemctl status docker |
出现下面这个界面就代表docker安装成功。
- 配置镜像加速器,默认是到国外拉取镜像速度慢,可以配置国内的镜像如：阿里、网易等等。下面配置一下网易的镜像加速器。打开docker的配置文件: /etc/docker/daemon.json文件：
| [root@localhost docker]# vi /etc/docker/daemon.json |
配置如下:
| {"registry-mirrors": ["http://hub-mirror.c.163.com"]} |
配置完后:wq保存配置并重启docker 一定要重启不然加速是不会生效的！！！
copy
| [root@localhost docker]# service docker restart |
