1、下载docker的安装文件

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

由于公司OpenStack用的docker版本是18.09.0

所以,下载的是:docker-18.09.0-ce.tgz 这个压缩文件

 

 

2、上传docker-18.09.0-ce.tgz 到系统,用ftp工具上传即可

 

3、解压

tar -zxvf docker-18.06.3-ce.tgz

 

4、将解压出来的docker文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

 

 5、进入/etc/systemd/system/目录,并创建docker.service文件

cd /etc/systemd/system/
vi docker.service

 

6、将以下内容复制进去(192.168.100.108改为你的服务器IP

[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=192.168.100.108
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

 

7、给docker.service文件添加执行权限

chmod 777 /etc/systemd/system/docker.service 

 

8、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 

 

9、启动

systemctl start docker

 

10、设置开机启动

systemctl enable docker.service

 

11、查看docker状态

systemctl status docker

出现下面这个界面就代表docker安装成功:

 

 

12、配置镜像加速器,默认是到国外拉取镜像速度慢,可以配置国内的镜像如:阿里、网易等等。

下面配置一下网易的镜像加速器。打开docker的配置文件: /etc/docker/daemon.json文件:

vi /etc/docker/daemon.json

配置如下:

{"registry-mirrors": ["http://hub-mirror.c.163.com"]}

 

13、保存配置并重启docker 一定要重启不然加速是不会生效的!!!

service docker restart

 

14、测试docker导入安装镜像

h1_01_import_images.sh 

 

 导入镜像

查看镜像

 

运行容器并进入

 

 

 OK,到此没有问题,无网环境安装docker成功!!
