综合：配置高可用、负载均衡

• 环境说明：LVS-DR模式

• • client1：eth0->192.168.88.10
  • lvs1：eth0->192.168.88.5
  • lvs2：eth0->192.168.88.6
  • web1：eth0->192.168.88.100
  • web2：eth0->192.168.88.200

• 环境准备

# 关闭2台web服务器上的keepalived，并卸载
[root@pubserver cluster]# vim 08-rm-keepalived.yml
---
- name: remove keepalived
  hosts: webservers
  tasks:
    - name: stop keepalived       # 停服务
      service:

    - name: uninstall keepalived   # 卸载
      yum:
        name: keepalived
        state: absent
[root@pubserver cluster]# ansible-playbook 08-rm-keepalived.yml


# 创建新虚拟机lvs2
[root@myhost ~]# vm clone lvs2


# 为lvs2设置ip地址
[root@myhost ~]# vm setip lvs2 192.168.88.6


# 连接
[root@myhost ~]# ssh 192.168.88.6
