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 -1)
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

#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

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，
