编译Nginx

[root@zabbix-web01 nginx-1.18.0]# ./configure --prefix=/apps/nginx --with-http_stub_status_module

编译安装

[root@zabbix-web01 nginx-1.18.0]# make && make install

如果是apt源安装的nginx默认路径在；优先级高的原因在于default_server，删除如下：

[root@zabbix-web02 ~]# vim /etc/nginx/sites-enabled/default

范例：

[root@zabbix-web02 ~]# cat /etc/nginx/conf.d/nginx-statu.conf
server{
   listen 80 default_server;
   server_name _;
   location / {
      root /var/www/html;
      index index.html;
   }
   location /ngx_status {
      stub_status;
      allow 172.31.1.0/21;
      allow 127.0.0.1;
      deny all;
   }
}

修改配置文件

[root@zabbix-web01 nginx-1.18.0]# vim /apps/nginx/conf/nginx.conf

    location /nginx_status {
        stub_status;
        allow 172.31.1.0/21;
        allow 127.0.0.1;
        deny all;
    }

检查语法

[root@zabbix-web01 nginx-1.18.0]# /apps/nginx/sbin/nginx -t
nginx: [warn] low address bits of 172.31.1.0/21 are meaningless in /apps/nginx/conf/nginx.conf:50
nginx: the configuration file /apps/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx/conf/nginx.conf test is successful

启动

[root@zabbix-web01 nginx-1.18.0]# /apps/nginx/sbin/nginx
