篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ansible自动化部署50-100台规模企业级架构相关的知识，希望对你有一定的参考价值。
1、项目规划：搭建50-100台规模的集群实战设计方案2、利用多台服务器进行cobbler无人值守装机
3、管理机（yum,rpm,ntp,pptp,jumpserver,ssh key,ansible,saltstack）
4、搭建backup(rsync 这个集群定时备份)
5、共享存储nfs01(nfs服务、实时同步（sersync+rsync)
6、独立的mysql数据库服务
7、LNMP web服务（nginx+php,用户文件挂到存储，文本数据放到DB，优化）
8、NGINX 反向代理负载均衡（nginx）
9、利用keepalive实现负载均衡集群高可用
10、搭建yum仓库,定制rpm软件包,提供整个集群中所需软件
11、利用zabbix进行全网监控
这里是在虚拟机上进行试验,受限制没办法开那么多机器,但是思路和具体的方法就是这样
至于多少台服务器,那只是一个数字!
- hosts: daya
tasks:
- name: yum client
script: /server/scripts/yum_client.sh 这个脚本就具体内容如下:
- name: hosts copy
copy: src=/etc/hosts dest=/etc/hosts force=yes
[[email protected] ansible-playbook]# cat /server/scripts/yum_client.sh 修改所有机器yum源指向管理机
#!/bin/bash

cd /etc/yum.repos.d/
mv *.repo /yum_bak
cat >/etc/yum.repos.d/local.repo<<EOF

EOF
