原创docker dcos 的安装

原创哈,上个星期无意间发现了一个可以好东西

DC/OS

https://dcos.io 这个是官网哈

然后就痛苦的折磨了一个多星期;

基本是参照到https://dcos.io/docs/1.7/administration/installing/custom/advanced/ 这个来弄的，中间遇到不少坑

基本的docker 那些自行安装哈，只写一些细节上面的东西

mkdir /tmp/dcos && cd /tmp/dcos
curl -O https://downloads.dcos.io/dcos/EarlyAccess/dcos_generate_config.sh #这个有点久哈 550M

然后创建对应的目录：

├── dcos-genconf.14509fe1e7899f4395-3a2b7e03c45cd615da.tar
├── dcos_generate_config.sh
└── genconf
    ├── config.yaml
    └── ip-detect

genconf 这个文件夹的内容我放在github上面了 https://github.com/jackluo2012/dcos-genconf

先看看config.yaml 中的内容:

---
bootstrap_url: http://192.168.1.58:8080 #这个是配置服务器的地址，等会要从这里面下载内容
cluster_name: 'DC/OS' #名称
exhibitor_storage_backend: static #存储方式
ip_detect_filename: /genconf/ip-detect #路由检测，应该是哈
master_list:
- 192.168.1.100 #主机地址
resolvers:
- 192.168.1.254 #这个是dns
- 119.6.6.6 #这个是
oauth_enabled: 'false' #这个是验证，最好关闭，因为是内网，读者可以开启哈，
telemetry_enabled: 'false'#这个也是验证

ip-detect

#!/usr/bin/env bash
set -o nounset -o errexit
export PATH=/usr/sbin:/usr/bin:$PATH
echo $(ip addr show enp0s8 | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | head -)

然后就是

bash dcos_generate_config.sh #放生全局的配置信息
docker run -d -p 8080:80 --name nginx -v $PWD/genconf/serve:/usr/share/nginx/html:ro index.alauda.cn/library/nginx #这个是放到容器里面了
########这个可以测试一下，可以问题了不，我映射的是8080端口,服务器的地址是 192.168.1.58:8080 这个是主服务器的配置地址

下面来配置 master:

$ ssh root@192.168.1.100 #连接到master上面
$ mkdir /tmp/dcos && cd /tmp/dcos #放到临时目录下面哈
$ curl -O http://192.168.1.58:8080/dcos_install.sh #下载刚才的文件

然后就是

[root@localhost dcos]# bash dcos_install.sh master

Checking Docker is configured with a production storage driver: FAIL (devicemapper, /dev/loop0)

Docker is configured to use the devicemapper storage driver with a loopback
device behind it. This is highly recommended against by Docker and the
community at large for production use[][]. See the docker documentation on
selecting an alternate storage driver, or use alternate storage than loopback
for the devicemapper driver.

#上面是做一些环境检查，如果没有自行安装软件，还有端口检查，因为我是在虚拟机面装的，注意上面有一个FAIL,怎么办呢，动态改了一下shell脚本，把
那个==改成 != ,如果不知道怎么改，留言吧，

294 if [[ "${data_file}" != /dev/loop* ]]; then #在 294行哈

Setting and starting DC/OS

这样应该就安装好了，可以访问 http://192.168.1.100/这个了

slave 的略了，唯一下载的时候,就用

sudo bash dcos_install.sh slave

如果有不明白的欢迎留言哈，
