centos7下docker二进制安装

问题描述:

  内网离线环境下,安装docker.二进制来的还是快点,或者内网搭建yum的epel仓库!

环境:

 centos7.x

 docker-18.9.0 x86_64  static //二进制

解决方法:

1、download:

  https://download.docker.com/linux/static/stable/x86_64/

2、kernel ack

[root@lab-210 ~]# uname -r     //kerner3.10.+   centois7.x 内核都是3.10+,此举只是为了验证
3.10.0-862.el7.x86_64

3、setup

docker-18.06.1-ce.tgz

tar zxf docker-18.06.1-ce.tgz && mv docker/* /usr/bin/ && rm -rf docker*.tgz    //解压切移动binary到 /usr/bin

注意:如果移动到别的目录有点问题,systemctl脚本启动不起来,具体原因还在寻找中

4、systemd docker.service

vim /etc/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
# 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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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

5、grant privilege  

chmod +x /etc/systemd/system/docker.service

systemctl daemon-reload   //重载systemd下 xxx.service文件
systemctl start docker       //启动Docker
systemctl enable docker.service   //设置开机自启

6、testing  docker

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

附录centos7.x安装脚本  install.sh

#!/bin/bash
set -x

#var
unamer=`uname -r |cut -d'.' -f1-2`

#kernel 3.10+
if [[ $unamer -lt 3.10 ]];then
	echo "the linux kernel too lower" && exit 8
fi

#setup
tar zxf  docker-18.06.1-ce.tgz && mv docker/* /usr/bin/ && rm -rf docker*

#systemd config
cat >/etc/systemd/system/docker.service <<-EOF
