一、安装docker(二进制方式)
1、下载docker二进制包
wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.14.tgz
2、添加执行权限并解压
tar -zxf docker-19.03.14.tgz && chmod +x docker/*
3、二进制文件放到/usr/bin下:mv docker/* /usr/bin/
4、创建docker配置文件
mkdir -p /etc/docker
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://s1x5r8bz.mirror.aliyuncs.com"]
}
5、docker 被systemd管理
vim /usr/lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target
6、重新加载配置文件:
systemctl daemon-reload
7、启动并设为开机自启:
systemctl start docker && systemctl enable docker
8、查看版本:docker --version
二、安装docker-compose
1、使用github下载
curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
2、添加执行权限:
chmod +x /usr/local/bin/docker-compose
3、查看版本:
docker-compose -v
三、升级docker-compose版本
1、查看docker-compose版本:docker-compose -v
2、下载并替换版本:
curl -L https://github.com/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
3、添加替换文件的执行权限:
chmod +x /usr/local/bin/docker-compose
4、查看版本:docker-compose -v
