[root@linux-node1 ~]# tree /srv/salt/prod/haproxy/

└── install.sls

1 directory, 3 files

##可以看到,haproxy的启动脚本,安装就可以完成了,有人可能存在疑惑,为啥haproxy的配置文件不放在这边呢?原因是配置文件有差异性,并不是所有的配置文件都相同的。。这样的差异性我们可以通过上一级新建目录来实现。

##haproxy没有起来,报错,,可以手动启动下试试:
[root@linux-node1 ~]# /etc/init.d/haproxy start
Starting haproxy: [ALERT] 136/233319 (6666) : Starting frontend frontend_www_example_com: cannot bind socket [10.20.23.11:80]
[失败]
##原因是80端口被占用,netstat -lntup查看,,果然httpd正在运行,,把httpd关闭,重启salt '*' state.highstate 即可

##httpd的默认端口,改为8080,两台都要,,然后保存退出,,启动httpd
vim /etc/httpd/conf/httpd.conf
Listen 8080

此时就可以访问haproxy了
