监控基于Linux主机的Apache  

2012-09-27 15:53:39|  分类: rhel_监控 |  标签: |字号 订阅

8.1 要监控基于Linux主机的Apache,可以在添加主机时直接选择“Linux主机-Apahce”主机模板。

8.2 在被监控的Linux主机上,需要对Apache做以下配置:

8.2.1 加载mod_status.so模块。大多数Apache已经加载了该模块,但您依然需要检查您的Apache是否已加载该模块。编辑您的httpd.conf,查看是否有以下行:
LoadModule status_module modules/mod_status.so

如果没有,您需要手动添加。如果加载该模块失败,您需要重新编译Apache或复制可用的模块文件,然后加载

8.2.2 启用Aapche的状态功能,编辑您的httpd.conf,添加以下设置:
ExtendedStatus On

    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from 192.168.254.253

修改192.168.254.253为您的CactiEZ中文版IP地址。

8.3.3 保存退出并重启Apache

8.4 测试Apache配置是否成功,登录CactiEZ中文版,输入:
# links http://Apache服务器IP/server-status

8.5 如果能看到类似以下数据表示Apache配置成功:
Apache Server Status for 192.168.0.20
Server Version: Apache/2.2.15 (Unix) DAV/2 
Server Built: Aug 14 2010 08:53:20
