2.nginx编译安装参考??https://blog.51cto.com/taowenwu/4864239??
3.zabbix-agent自动安装脚本??https://blog.51cto.com/taowenwu/5213052??
4.配置文件修改

root@ubuntu:/apps/zabbix_agent/conf.d# cat nginx.conf
UserParameter=nginx.status[*],/bin/bash /apps/zabbix_agent/conf.d/nginx_status.sh $1 $2 $3

5.监控脚本nginx_status.sh

#!/bin/bash

nginx_status_fun() #函数内容
NGINX_PORT=$1#端口，函数的第一个参数是脚本的第二个参数，即脚本的第二个参数是段端口号
NGINX_COMMAND=$2#命令，函数的第二个参数是脚本的第三个参数，即脚本的第三个参数是命令
nginx_active()#获取nginx_active数量，以下相同，这是开启了nginx状态但是只能从本机看到
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| grep Active | awk print $NF

nginx_reading() #获取nginx_reading状态的数量
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| grep Reading | awk print $2

nginx_writing()
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| grep Writing | awk print $4

nginx_waiting()
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| grep Waiting | awk print $6

nginx_accepts()
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| awk NR==3 | awk print $1

nginx_handled()
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| awk NR==3 | awk print $2

nginx_requests()
/usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| awk NR==3 | awk print $3
