Zabbix版本：3.2.4
实战监控Apache
1.1 源码编译构建apache服务
#为了避免冲突，若系统中已经安装httpd服务，务必删除
[root@apache ~]# rpm -q httpd
package httpd is not installed
[root@apache ~]# /etc/init.d/iptables stop
[root@apache ~]# setenforce 0
setenforce: SELinux is disabled
#源码构建apache
[root@apache httpd-2.2.17]# tar xf httpd-2.2.17.tar.gz -C /usr/src/
[root@apache httpd-2.2.17]# cd /usr/src/httpd-2.2.17/
[root@apache httpd-2.2.17]# ./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi && make && make install
[root@apache httpd-2.2.17]# cd /usr/local/httpd/
[root@apache httpd]# ls
bin build cgi-bin conf error htdocs icons include lib logs man manual modules
[root@apache httpd]# ln -s /usr/local/httpd/bin/* /usr/local/bin/
[root@apache httpd]# cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
[root@apache httpd]# chmod +x /etc/init.d/httpd
[root@apache ~]# cd /usr/local/httpd/htdocs/
[root@apache htdocs]# echo "`hostname -I` I am apache" > index.html
[root@apache htdocs]# cat index.html
192.168.0.222 I am apache
[root@apache conf]# awk '/#ServerName/{print NR,$0}' httpd.conf
97 #ServerName www.example.com:80
[root@apache conf]# sed -i -e '97 s/#//;s/example/yunjisuan/' httpd.conf
[root@apache conf]# sed -n '97p' httpd.conf
ServerName www.yunjisuan.com:80
[root@apache conf]# /etc/init.d/httpd start
[root@apache conf]# netstat -antup | grep httpd
tcp 0 0 :::80 :::* LISTEN 53288/httpd
[root@apache conf]# echo "`hostname -I` www.yunjisuan.com" >> /etc/hosts
[root@apache conf]# tail -1 /etc/hosts
192.168.0.222 www.yunjisuan.com
[root@apache conf]# curl www.yunjisuan.com
192.168.0.222 I am apache
1.2 开启apache状态页
要打开apache的ServerStatus页面，需要在httpd.conf文件最下边加入代码段
ExtendedStatus On
<location /server-status>
SetHandler server-status
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</location>
最后，重启动apache即可
1.3 下载apache zabbix模版并解压
#从如下地址下载apache zabbix模版：
[root@apache ~]# wget https://github.com/lorf/zapache/archive/master.zip
#解压zip格式压缩文件
[root@apache ~]# unzip master
[root@apache ~]# ls -d zapache-master
zapache-master
[root@apache ~]# cd zapache-master/
[root@apache ~]# tree zapache-master/
zapache-master/
├── httpd-server-status.conf.sample
├── README.md
├── userparameter_zapache.conf.sample

#此模版文件中包含了监控apache的脚本文件，zabbix的apache模版文件，还有客户端zabbix自定义传key文件。
#首先将zapache放到需要监控的apache服务器上的/etc/zabbix/scripts目录下，如果没有scripts目录，自行创建一个即可。然后执行授权：
[root@apache zapache-master]# chmod 755 /etc/zabbix/scripts/zapache
[root@apache scripts]# cd /etc/zabbix/scripts/
[root@apache scripts]# ./zapache
zapache version: 1.5

#接着将userparameter_zapache.conf.sample文件放到/etc/zabbix/zabbix_agentd.d目录下，并重命名为userparameter_zapache.conf文件,然后修改键值命令的路径。
#最后，重启zabbix-agent服务
[root@apache zapache-master]# mv userparameter_zapache.conf.sample /etc/zabbix/zabbix_agentd.d/userparameter_zapache.conf
[root@apache zabbix_agentd.d]# tail -1 userparameter_zapache.conf
UserParameter=zapache[*],/etc/zabbix/scripts/zapache \$1 #本行要修改
[root@apache zapache-master]# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [ OK ]

#我们发现脚本需要传递两个参数，即url和选项
#然后我们在zabbix-server端进行键值测试
[root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[127.0.0.1 TotalAccesses]"

[root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[www.yunjisuan.com version]"

[root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[www.yunjisuan.com ping]"

1.5 在zabbix-server的Web页面上监控apache
1.5.1 创建一个监控apache的主机
1.5.2 导入带有apache监控项的模版
zabbix默认并没有监控apache的监控项模版。我们需要将它导入到apache中。在之前解压出来的目录中，有待导入的web模版
[root@apache ~]# tree zapache-master/
zapache-master/
├── httpd-server-status.conf.sample
├── README.md
├── zapache-template-active.xml #Web模版
└── zapache-template.xml #Web模版
0 directories, 4 files
我们将这两个.xml后缀的拷贝到windows上，然后从Web界面导入进去
导入以后Web端就有监控apache的监控项模版了
1.5.3 将模版链接到apache主机
