centos离线安装docker

转载自：https://blog.csdn.net/weixin_45107899/article/details/125503680

===========================

一、步骤
1. 安装包官方地址：https://download.docker.com/linux/static/stable/x86_64/

选择18.06.3-ce

2.解压
3.将解压出来的docker文件复制到 /usr/bin/ 目录下
4.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
5.启动docker
6.docker环境检查

一、步骤
1. 安装包官方地址：https://download.docker.com/linux/static/stable/x86_64/
可以先下载到本地，然后通过ftp工具上传到服务器上，或者在服务器上使用命令下载

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

2.解压
代码如下（示例）：

tar -zxvf docker-18.06.3-ce.tgz

3.将解压出来的docker文件复制到 /usr/bin/ 目录下
代码如下（示例）：

cp docker/* /usr/bin/

4.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
代码如下（示例）：

[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docker
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

上图表示docker已安装成功
