apache安装参考:https://www.tracymc.cn/archives/646
前提:
apache需要开启mod_status模块

具体步骤:
1.修改配置
[root@test ~]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built: Oct 19 2017 20:39:16
[root@test modules]# ll /etc/httpd/modules/|grep mod_status //http默认安装路径为/etc/httpd/
-rwxr-xr-x 1 root root 23464 10月 20 2017 mod_status.so //说明mod_status模块已经加载
新增httpd-info.conf配置,内容如下:
[root@test conf]# cat /etc/httpd/conf.d/httpd-info.conf
<Location /server-status>
SetHandler server-status
Order allow,deny
Allow from localhost //只允许本机访问
</Location>
ExtendedStatus On

主机浏览器打开http://127.0.0.1/server-status验证apache配置修改是否生效,如下:

2.下载模板
[root@test home]# wget https://github.com/lorf/zapache/archive/master.zip
[root@test home]# unzip master.zip
[root@test home]# cd zapache-master/
[root@test zapache-master]# ll

-rw-r--r-- 1 root root 676 4月 22 2016 httpd-server-status.conf.sample //用于配置server-status的模板,上面已经配置过
-rw-r--r-- 1 root root 1780 4月 22 2016 README.md
-rw-r--r-- 1 root root 224 4月 22 2016 userparameter_zapache.conf.sample //zabbix的userparameter模板
-rwxr-xr-x 1 root root 6110 4月 22 2016 zapache //监控脚本
-rw-r--r-- 1 root root 52258 4月 22 2016 zapache-template-active.xml //模板
-rw-r--r-- 1 root root 52024 4月 22 2016 zapache-template.xml //模板
[root@test zapache-master]# cp zapache /etc/zabbix/scripts/ //将脚本复制到脚本执行目录
[root@test ~]# cat /etc/zabbix/zabbix_agentd.conf |grep conf|grep -v '#' //yum安装zabbix的话agent默认配置文件为/etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd.d/*.conf //你懂的,包含/etc/zabbix/zabbix_agentd.d下面的配置
[root@test zapache-master]# cp userparameter_zapache.conf.sample /etc/zabbix/zabbix_agentd.d/
[root@test zabbix_agentd.d]# ll

-rwxrwxrwx 1 root root 26 2月 20 2017 libzbxpgsql.conf
-rwxrwxrwx 1 root root 1531 5月 9 18:03 userparameter_mysql.conf
-rw-r--r-- 1 root root 224 6月 13 22:29 userparameter_zapache.conf.sample
[root@test zabbix_agentd.d]# mv userparameter_zapache.conf.sample userparameter_zapache.conf
将userparameter_zapache.conf脚本路径修改为自己本地的路径,修改后的内容如下：
[root@test zabbix_agentd.d]# cat userparameter_zapache.conf
#
# This is a sample zabbix_agentd config file.
# Put it to /etc/zabbix_agentd.conf.d or otherwise integrate into agent config.
# Edit to your needs.
#
UserParameter=zapache[*],/etc/zabbix/scripts/zapache \$1 //与上面的脚本执行目录一致
