工程师计划 中间件 Centos7.6离线安装docker19.3.9

Centos7.6离线安装docker19.3.9

离线安装模式

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-19.03.9.tgz

2 解压

tar -xvf docker-19.03.9.tgz

3 将解压出来的docker文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

4 在/etc/systemd/system/目录下新增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

systemctl status docker
