Zabbix 监控获取apache_status

以下操作均在zabbix-agent端操作：

• 初始化(执行脚本)

sh init.sh           

• httpd的安装与启动（二进制）

yum install -y httpd*  #安装httpd           

systemctl  start httpd.service；systemctl  enable httpd.service #服务的启动与开机自启            

ss -ant |grep :80 #查看httpd的80是否起来
LISTEN     0      128          *:10050                    *:*                   users:(("zabbix_agentd",pid=16735,fd=4),("zabbix_agentd",pid=16734,fd=4),("zabbix_agentd",pid=16733,fd=4),("zabbix_agentd",pid=16732,fd=4),("zabbix_agentd",pid=16731,fd=4),("zabbix_agentd",pid=16730,fd=4))
LISTEN     0      128         :::10050                   :::*                   users:(("zabbix_agentd",pid=16735,fd=5),("zabbix_agentd",pid=16734,fd=5),("zabbix_agentd",pid=16733,fd=5),("zabbix_agentd",pid=16732,fd=5),("zabbix_agentd",pid=16731,fd=5),("zabbix_agentd",pid=16730,fd=5))           

在/etc/httpd/conf/httpd.conf的末尾加上如下代码
ExtendedStatus On
<location /server-status>
   SetHandler server-status
   Order Allow,Deny
   Allow from all
</location>           

systemctl restart httpd.service #修改配置文件之后重启服务           

#执行下方命令看是否status是否配置成功
/usr/bin/curl --insecure --silent --location http://localhost/server-status?auto

• 部署zabbix-agent端
  1. 一键部署

  2. 分步部署：

     -配置zabbix-repo

rpm -Uvh https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm           

-安装agent端软件

yum install zabbix-agent           

-修改配置启动agent端服务

vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.122.105           //被动模式 zabbix-server-ip
ServerActive=192.168.122.105    //主动模式  zabbix-server-ip
Hostname=Zabbix server         //Agent端主机名，最终显示在监控页面上的名字
UnsafeUserParameters=1        //是否限制用户自定义keys使用特殊字符           

-服务的启动与开机自启动

systemctl start zabbix-agent           

netstat -antp | grep agent
LISTEN     0      128          *:10050                    *:*                   users:(("zabbix_agentd",pid=16735,fd=4),("zabbix_agentd",pid=16734,fd=4),("zabbix_agentd",pid=16733,fd=4),("zabbix_agentd",pid=16732,fd=4),("zabbix_agentd",pid=16731,fd=4),("zabbix_agentd",pid=16730,fd=4))
LISTEN     0      128         :::10050                   :::*                   users:(("zabbix_agentd",pid=16735,fd=5),("zabbix_agentd",pid=16734,fd=5),("zabbix_agentd",pid=16733,fd=5),("zabbix_agentd",pid=16732,fd=5),("zabbix_agentd",pid=16731,fd=5),("zabbix_agentd",pid=16730,fd=5))           

-配置snmp

yum -y install net-snmp net-snmp-utils           

vim /etc/snmp/snmpd.conf 
com2sec notConfigUser  192.168.122.105    public  
access  notConfigGroup ""  any  noauth  exact  all none none
view all    included  .1    80           

systemctl  start snmpd;systemctl  enable snmpd           

ss -anup |grep snmp
UNCONN     0      0            *:161                      *:*                   users:(("snmpd",pid=4315,fd=6))           

• 准备获取status的脚本(脚本内容:

cd /etc/zabbix
mkdir scripts
touch apache_status.sh
chomd +x apache_status.sh           

把脚本执行一边，检查脚本看是否能够正常获取到数值。

sh apache_status.sh TotalAccesses
37552           

• 自定义key

cd /etc/zabbix/zabbix_agentd.d
touch apache_status.conf
cat apache_status.conf
UserParameter=apache.status[*],/etc/zabbix/scripts/apache_status.sh $1           

• 在zabbix上添加监控项

  

创建完主机之后先查看一下主机的状态，为绿色就正常，为红色或者灰色则需要排查问题。

根据上图添加脚本里获取的所有的值为监控项

查看状态是否为已启用的状态，不是则需要排查。

如果有最新数据，监控项则配置成功。

根据业务情况配置触发器等。
