在include中创建新的conf文件

[root@linux-node2 ~]# ll /etc/zabbix/
total 12
-rw-r--r-- 1 root root 10353 Aug 27 15:06 zabbix_agentd.conf
drwxr-xr-x 2 root root    61 Aug 27 15:20 zabbix_agentd.d

[root@linux-node2 ~]# grep "^[a-Z]" /etc/zabbix/zabbix_agentd.conf 
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.56.11
ServerActive=127.0.0.1
Hostname=linux-node2.example.com
Include=/etc/zabbix/zabbix_agentd.d/
UnsafeUserParameters=1

创建的conf文件

[root@linux-node2 zabbix_agentd.d]# pwd
/etc/zabbix/zabbix_agentd.d
    
[root@linux-node2 zabbix_agentd.d]# cat zabbix_nginx.conf 
UserParameter=nginx-alive,curl --head -s http://127.0.0.1/ | grep "200 OK" | wc -l

在监控服务器上安装zabbix_get测试是否能获取到值

[root@linux-node1 ~]# yum -y install zabbix-get

[root@linux-node1 ~]# zabbix_get -s 192.168.56.12 -k nginx-alive
1

在监控的主机中创建监控项

分割线----------------------------------------------------------------------------------------------------------------

在linux-node2上传我们自己写好的脚本

[root@linux-node2 zabbix]# pwd
/etc/zabbix
[root@linux-node2 zabbix]# ll
-rwxr-xr-x 1 zabbix zabbix  1288 Oct 29 17:10 zabbix_nginx_plugin.sh      加上对应的权限

开启zabbix-agent上UnsafeUserParameters=1

[root@linux-node2 ~]# grep '^[a-Z]' /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
