配置打开状态页

修改配置文件 Server 配置块中添加：
        location /nginx_status {
            stub_status;
            allow 10.0.0.0/24;
            allow 127.0.0.1;
        }

root@78:/apps/nginx# sbin/nginx -t              测试配置文件
nginx: the configuration file /apps/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx/conf/nginx.conf test is successful
root@78:/apps/nginx# sbin/nginx                  启动nginx
root@78:/apps/nginx# ss -ntl | grep 80           确认启动

监控脚本

7种状态，使用awk命令获取数据，其中

1. awk pattern // 中使用变量需要先用单引号再用双引号
2. -F '[[:space:]]+|:' 空格和：同时作为分隔符，需要调整print $x
