Linux安装部署docker

1.获取docker安装包

wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz

2. 解压

tar -zxvf docker-18.06.3-ce.tgz

3.将解压文件放到/usr/bin/

cp docker/* /usr/bin/

4. 创建docker.service文件

进入 /etc/systemd/system/ 目录,并创建 docker.service 文件，内容如下，这样可以将docker注册为service服务

[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=127.0.0.1 ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process # restart the docker process if it exits prematurely Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target

# 此处的–insecure-registry=127.0.0.1（此处改成你私服ip）设置是针对有搭建了自己私服Harbor时允许docker进行不安全的访问，否则访问将会被拒绝。

5. 启动

# 给docker.service文件添加执行权限

chmod +x /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）

systemctl daemon-reload

# 启动 systemctl start docker

# 设置开机启动 systemctl enable docker.service

# 查看docker服务状态

[root@localhost system]# systemctl status docker

安装docker-compose

# docker-compose下载并放到/usr/local/bin/下面：

curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 下载好docker-compose的前提下，拷贝到指定位置

sudo cp docker-compose /usr/local/bin/docker-compose

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

sudo chmod +x /usr/bin/docker-compose

docker-compose -v

# 最后使用 docker-compose -v 命令测试是否安装成功（如果提示“没有那个文件或目录”可以重启下服务器再试试）
