[root@localhost /]#

五、 将当前用户添加到docker用户组

vagrant为登录用户名称，根据自己机器登录名称设定

script
1
2
3
[root@localhost /]# sudo usermod -aG docker vagrant
[root@localhost /]# sudo usermod -aG docker root
[root@localhost /]#

六、 设置docker镜像下载源，指定cgroup驱动

查看/etc/docker下是否有daemon.json文件，如果有手动修改，如果没有则直接执行如下命令

  1. 查看daemon.json是否存在，我这里不存在，执行第2步增加docker配置
script
1
2
3
4
[root@localhost /]# cd /etc/docker/
[root@localhost docker]# ls
key.json
[root@localhost docker]#
  1. 增加docker配置，并查看配置
    https://1mbc3b4s.mirror.aliyuncs.com的获取 阿里云镜像地址
    如果之前启动过docker,修改完成之后需要重启
    sudo systemctl daemon-reload && sudo systemctl restart docker
script
1
2
3

sudo tee /etc/docker/daemon.json <<-'EOF' 
{
    "registry-mirrors": ["https://1mbc3b4s.mirror.aliyuncs.com"],
    "exec-opts": ["native.cgroupdriver=systemd"]
} 
EOF
[root@localhost docker]# cat /etc/docker/daemon.json
{
    "registry-mirrors": ["https://1mbc3b4s.mirror.aliyuncs.com"],
    "exec-opts": ["native.cgroupdriver=systemd"]
}
[root@localhost docker]#

七、 启动docker

script
1
2
[root@localhost /]# sudo systemctl start docker
[root@localhost /]#

八、 查看docker是否安装成功

这里可以看到docker的版本为19.03.11，增加了docker0网络

九、 设置docker开机启动

script

3
[root@localhost /]# sudo systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@localhost /]#

十、 安装docker-compose（墙裂建议） docker-compose安装文档地址

  1. 下载docker-compose
    sudo curl -L “https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)” -o /usr/local/bin/docker-compose
  2. 赋予docker-compose权限
    sudo chmod +x /usr/local/bin/docker-compose
  3. 添加docker-compose软连接
    sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
script

[root@xincan /]# docker-compose --version
docker-compose version 1.26.0, build d4451659
[root@xincan /]#

十、 安装docker-compose（墙裂建议）

  1. 安装bash-completion
    yum install -y bash-completion
  2. 赋予docker-compose权限
    sudo chmod +x /usr/local/bin/docker-compose
  3. 添加docker-compose软连接
    sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
script
1
[root@xincan /]#yum install -y bash-completion
