Zabbix监控Apache

Posted 2022-05-27 一点点积累

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
├── zapache
├── zapache-template-active.xml
└── zapache-template.xml
0 directories, 6 files
#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  ]
Starting Zabbix agent:                                     [  OK  ]

1.4 测试键值

#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]"
9
[root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[www.yunjisuan.com version]"
1.5
[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
