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 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
