saltstack搭建集群2
功能模块-----keepalived模块写之前先找一台主机源码安装测试

# salt '*' state.sls cluster.haproxy-outside-keepalived env=prod#测试一下
指定服务器执行keepalived模块
# cat /srv/salt/base/top.sls
base:

- init.env_init
prod:
'node1':
- cluster.haproxy-outside
- cluster.haproxy-outside-keepalived
'node2':
- cluster.haproxy-outside
- cluster.haproxy-outside-keepalived
# salt '*' state.highstate #到这步执行成功的话就实现了keepalived+haproxy
遇到问题：发现keepalived 虚拟vip写不上去
查看日志 cat /var/log/messages，发现下面一句
Aug 11 15:10:12 node1 Keepalived_vrrp: VRRP_Instance(haproxy_ha{) sending 0 priority
haproxy_ha后面打了个空格解决
vrrp_instance haproxy_ha {
