linux下如何在內網安裝docker

一、基礎環境

1、作業系統：CentOS 7.3

2、Docker版本：18.06.1

#二、Docker安裝

1、解壓縮

tar -xvf docker-18.06.1-ce.tgz

2、將解壓縮出來的docker檔案內容移到/usr/bin/ 目錄下

cp docker/* /usr/bin/

3、將docker註冊為service

vim /etc/systemd/system/docker.service

將下列配置加到docker.service中並儲存。

[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
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

4、啟動

chmod +x /etc/systemd/system/docker.service    #添加文件权限并启动docker
systemctl daemon-reload    #重载unit配置文件
systemctl start docker    #启动Docker
systemctl enable docker.service  #设置开机自启

5、驗證

systemctl status docker   #查看Docker状态
docker -v   #查看Docker版本
