CentOS7.3服务器内网离线部署docker和容器

一、离线安装docker

1、获取yum仓库中的docker及其依赖包

1.1、获取docker的依赖包：

克隆一台相同环境的虚拟机，连上互联网，使用yum install docker命令，会提示需要的依赖包列表。CentOS7.3最小化安装环境会提示需要31个包：

yum install docker

1.4、将下载的安装包压缩打包，上传至需要安装docker的服务器

tar -zcf rpmdir.tgz rpmdir/
scp -P 22112 rpmdir.tgz user@192.168.33.44:/home/user

2、安装docker

登陆服务器并安装所有rpm包

tar -zxf rpmdir.tgz 
cd rpmdir
yum localinstall *

3、安装docker-compose

3.1、下载docker-compose：

打开链接https://github.com/docker/compose/releases，下载最新的docker-compose-Linux-x86_64

3.2、上传docker-compose：

通过scp拷贝docker-compose-Linux-x86_64到服务器，重新命名为docker-compose-Linux-x86_64_版本号，如：docker-compose-Linux-x86_64_1.23.2。

3.3、安装docker-compose：

登陆服务器，移动docker-compose-Linux-x86_64_1.23.2到/usr/local/bin/，并设置可执行权限：

mv docker-compose-Linux-x86_64_1.23.2 /usr/local/bin/
chmod +x /usr/local/bin/docker-compose-Linux-x86_64_1.23.2
ln -s /usr/local/bin/docker-compose-Linux-x86_64_1.23.2 /usr/local/bin/docker-compose

4、启动docker

4.1 启动docker会报错：

systemctl start docker
[container_package] # systemctl status docker.service
● docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)

Hint: Some lines were ellipsized, use -l to show in full.

“SELinux is not supported with the overlay2 graph driver on this kernel.”
这台机器的linux的内核中的SELinux不支持 overlay2 graph driver 。解决方法有两个，要么启动一个新内核，要么就在docker配置文件里面里禁用selinux。

4.2 修改/etc/sysconfig/docker

设置/etc/sysconfig/docker文件中的--selinux-enabled为--selinux-enabled=false。

cat /etc/sysconfig/docker
# /etc/sysconfig/docker

# Modify these options if you want to change the way the docker daemon runs
OPTIONS=‘--selinux-enabled=false --log-driver=journald --signature-verification=false‘
if [ -z "${DOCKER_CERT_PATH}" ]; then
DOCKER_CERT_PATH=/etc/docker
fi
...
--------------------------------------------------------------------
# 然后可正常启动docker
systemctl start docker

二、离线安装docker镜像

1、在克隆的服务器上安装docker，并pull镜像。

2、导出各个需要的镜像，如mysql：

docker save mysql:5.6 > mysql_5.6.tar

3、上传镜像包到内网服务器后导入服务器：

docker load < mysql_5.6.tar
docker tag mysql mysql:5.6
