## 前期准备 ##

### docker rpm ###

wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.12.6-1.el7.centos.x86_64.rpm
    wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.12.6-1.el7.centos.noarch.rpm

### harbor offline ###

wget https://github.com/vmware/harbor/releases/download/v1.2.0/harbor-offline-installer-v1.2.0.tgz
    curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o ./docker-compose

### 打包 Rancher Server 及各组件 image： ###

rancher/server:v1.6.10
    rancher/agent:v1.2.6
    rancher/network-manager:v0.7.8
    rancher/net:v0.11.9
    rancher/dns:v0.15.3
    rancher/metadata:v0.9.4
    rancher/healthcheck:v0.3.3
    rancher/lb-service-haproxy:v0.7.9
    rancher/scheduler:v0.8.2
    rancher/net:holder

如：

docker pull rancher/agent:v1.2.6
    docker save rancher/agent:v1.2.6 > agent126.tar

## 部署环境 ##

### 安装配置 docker (所有主机) ###

yum localinstall -y docker-engine-1.12.6-1.el7.centos.x86_64.rpm docker-engine-selinux-1.12.6-1.el7.centos.noarch.rpm
    
    注：如有依赖使用 ISO 做 yum 源

指向docker私有镜像库IP

vi /usr/lib/systemd/system/docker.service
    
    如修改为：
    
    ExecStart=/usr/bin/dockerd --insecure-registry=192.168.100.1:80（私有库地址:端口）

### 安装配置 Harbor ###

1.解压：
    tar -zxvf harbor-offline-installer-v1.2.0.tgz
    配置 harbor
    
    2.编辑harbor.cfg　
    vi harbor.cfg
    修改　hostname = IP
    harbor_admin_password = Rancher123
    
    3.运行 install.sh
    cp docker-compose /usr/local/bin/
    chmod +x /usr/local/bin/docker-compose
    ./install.sh
    
    4.添加项目
    a)通过浏览?访问harbor http://IP admin/Rancher123 登录
    b)添加名称为 'rancher' 的项目并设置为“公开”
    
    5.导入 images
    登录 docker login 私有仓库 IP:端口
    a) docker load -i agent126.tar
    b) docker tag rancher/agent:v1.2.6 192.168.100.1:80/rancher/agent:v1.2.6
    c) docker push 192.168.100.1:80/rancher/agent:v1.2.6
    按照以上方式将所有 Rancher image 导入私有镜像仓库

### 配置 Rancher 环境 ###

a) docker run -d --restart=unless-stopped -p 8080:8080 192.168.100.1:80/rancher/server:v1.6.10
    b) 登录 Rancher Server UI 　“Admin” -->“Settings”-->“Advanced Settings”编辑“registry.default=192.168.100.1:80”
    c) 添加Environments　“Manage Environments” -->"Add Environment"。 在创建完成后设置为默认并切换到该环境。
    d) 添加主机命令修改为
    docker run --rm --privileged -v/var/run/docker.sock:/var/run/docker.sock - v
    /var/lib/rancher:/var/lib/rancher 192.168.100.1:80/rancher/agent:v1.2.6 http://192.168.100.1:8080/ v1/scripts/8EBE0FB0C3DE0AA32047:1483142400000:7Md3cXHoSIYYwHADyBpGQNZavTE
    e) 在主机节点上修改 agent image tag
    docker tag 192.168.100.1:80/rancher/agent:v1.2.6 rancher/agent:v1.2.6
