1.安装nginx
[root@192_168_81_220 ~]# yum -y install nginx
2.开启状态监控页面
[root@192_168_81_220 ~]# vim /etc/nginx/nginx.conf
        location /nginx_status {
                stub_status;
        }
3.重启nginx
[root@192_168_81_220 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@192_168_81_220 ~]# systemctl start nginx
4.访问
[root@192_168_81_220 ~]# curl 192.168.81.220/nginx_status
Active connections: 1 
server accepts handled requests
 4 4 9

1.编写脚本
[root@192_168_81_220 ~]# cd /etc/zabbix/scripts/
[root@192_168_81_220 scripts]# vim tcp_zabbix.sh
#!/bin/bash
#这是一个简单的监控nginx状态值的脚本
#20201030   ---jxl
comm_para=$1
cachefile=/tmp/nginx_status.txt
port=80
cmd="/usr/bin/curl 127.0.0.1:$port/nginx_status"
file_time=`stat -c %Y $cachefile`
now_time=`date +%s`
rm_file=$(($now_time - $file_time))
if [ ! -f $cachefile ];then
  $cmd > $cachefile 2>/dev/null
fi
if [ $rm_file -gt 60 ];then
  rm -rf $cachefile
fi
if [ ! -f $cachefile ];then
  $cmd > $cachefile 2>/dev/null
fi
active() {
  cat $cachefile | awk '/Active/{print $NF}'
  exit 0;
}
accepts() {
  cat /tmp/nginx_status.txt | awk '{if(NR==3){print $1}}'
  exit 0;
}
handled(){ 
  cat /tmp/nginx_status.txt | awk '{if(NR==3){print $2}}'
  exit 0;
}
requests(){
  cat /tmp/nginx_status.txt | awk '{if(NR==3){print $3}}'
  exit 0;
}
reading() {
  cat /tmp/nginx_status.txt | awk '{if(NR==4){print $2}}'
  exit 0;
}
writing() {
  cat /tmp/nginx_status.txt | awk '{if(NR==4){print $4}}'
  exit 0;
}
waiting() {
  cat /tmp/nginx_status.txt | awk '{if(NR==4){print $6}}'
  exit 0;
}
check() {
        nginx_pro_count=`ps aux | grep nginx | grep -v grep | grep -v nginx_status.sh | wc -l`
  echo $nginx_pro_count
}

2.给执行权限并测试
[root@192_168_81_220 scripts]# chmod a+x tcp_zabbix.sh
[root@192_168_81_220 scripts]# sh tcp_zabbix.sh active
