我的 zabbix 出现“404 找不到页面”是怎么回事？
What's wrong of my zabbix with "404 Page Not Found"?
我已经在CentOS 6.8中安装了zabbix 2.4（使用rpms），psql 8.4.20，apache httpd 2.2.15，php 5.6.22，但是我的80端口被nginx占用了，所以我换了httpd 端口为 8080，当我重新启动 httpd 服务时：
[root@kf8 ~]# service httpd restart
stop httpd： [yes]
start httpd：[Mon Aug 22 19:40:03 2016] [warn] module php5_module is already loaded, skipping
[Mon Aug 22 19:40:03 2016] [warn] module php5_module is already loaded, skipping
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[yes]
[root@kf8 ~]#
我已经开始 zabbix-server/agent，下面列出的过程：
