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!

[root@m01 ansible-playbook]# cat /server/scripts/yum_client.sh   修改所有机器yum源指向管理机
