一、配置環境

1、配置路由

進入目錄/etc/docker/daemon.json

[root@itpux ~]# cd /etc/docker/
[root@itpux docker]# ls
key.json
[root@itpux docker]# vim daemon.json

增加路由：

{  "insecure-registries":[ "0.0.0.0/0"  ] 
}

2、重啟docker

[root@itpux docker]# systemctl stop docker.service 
[root@itpux docker]# systemctl start docker.service

3、查看路由配置

[root@itpux docker]# docker info

4、pull 鏡像

[root@itpux docker]# docker pull 10.236.4.81/rancher_1.6/rancher/server:v1.6.17
v1.6.17: Pulling from rancher_1.6/rancher/server

Digest: sha256:ca238ce2eef9d9d3b0ec5c2914c97096ba8adeb0e95ec0adb70cc1e1ce69d48d
Status: Downloaded newer image for 10.236.4.81/rancher_1.6/rancher/server:v1.6.17

二、安裝rancher/server

[root@itpux docker]# docker images 
REPOSITORY                               TAG                 IMAGE ID            CREATED             SIZE
nginx/nginxdocker                        v1                  bfcac0d54cf5        37 hours ago        415.3 MB
mysql/mysql5.7                           v1                  0d8579c7da5f        2 weeks ago         488.7 MB
centos                                   latest              75835a67d134        4 weeks ago         200.4 MB
10.236.4.81/rancher_1.6/rancher/server   v1.6.17             9ebf8344e85e        7 months ago        1.084 GB

1、192.168.26.189為虛擬機的IP地址（此時，容器只有1個10.236.4.81/rancher_1.6/rancher/server:v1.6.17 ）

[root@itpux docker]# docker run -d --restart=unless-stopped -p 8080:8080 -p 9345:9345 -p 443:443 -e CATTLE_BOOTSTRAP_REQUIRED_IMAGE=10.236.4.81/rancher_1.6/rancher/agent:v1.2.10 10.236.4.81/rancher_1.6/rancher/server:v1.6.17  --advertise-address 192.168.26.189

2、查看是否安裝完成

[root@itpux docker]# docker logs 7aba3e55e70377234e52a125f34e692d6e53d565a43250285a255d2a7762a916

[root@itpux docker]#

3、在物理機上使用google瀏覽器訪問是否完成安裝、

http://192.168.26.189:8080/env/1a5/apps/stacks

4、添加主機（添加后最新為12個容器）

[root@itpux ~]# sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher 10.236.4.81/rancher_1.6/rancher/agent:v1.2.10 http://192.168.26.189:8080/v1/scripts/C0E4D01E41EDE29982BA:1514678400000:CMcVll8tWD00bAfMSUATGWkvc

2）添加完主機后，全部容器是12個，並且全部已經自動啟動

[root@itpux ~]# docker ps -a
