centos 安装docker CE
0. 参考
1. 安装需要的包
sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
2. 添加仓库
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
3. 安装docker
sudo yum install docker-ce docker-ce-cli containerd.io
4. 启动
sudo systemctl start docker
5. 将当前用户加入docker组
groupadd docker
sudo gpasswd -a $USER docker
newgrp docker
解决使用docker命令时提示
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json": dial unix /var/run/docker.sock: connect: permission denied
centos 安装docker compose
1. 下载docker compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
2. 更改执行权限
sudo chmod +x /usr/local/bin/docker-compose
# centos7需要将 /usr/local/bin/添加到/etc/profile文件最后
vim /etc/profile
export PATH=$PATH:/usr/local/sbin:/usr/local/bin
source /etc/profile
3. 查询版本
docker-compose --version
