第一种方法： 官方模块：http://nginx.org/en/docs/http/ngx_http_limit_conn_module.html 1.在Nginx配置文件nginx.conf的http选项中添加如下内容 在nginx.conf的配置中添加了Nginx白名单 ### Nginx Limint config geo $limited{ default 1; 127.0.0.1 0; 192.168.100.18 0; } map $limited $limit{ 1 $binary_remote_addr; 0 ""; } limit_req_zone $limit zone=one:10m rate=5r/s; 2.在虚拟目录中直接应用 [root@frontend-01 ~]# cat /etc/nginx/conf.d/test.conf server{ listen 80; server_name yourdomain.com; root /yourdist/; access_log /yourdomain.com.access.log json; error_log /yourdomain.com.error.log warn; location /test/api/v3/ { ## 只针对api接口调用做Nginx IP地址限速 limit_req zone=one burst=10 nodelay; proxy_pass http://test; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Forwarded-Host $server_name; proxy_set_header Host $host; add_header Access-Control-Allow-Origin *; add_header Access-Control-Allow-Headers "accept, content-type"; } location /test/auth/v3/ { proxy_pass http://test; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Forwarded-Host $server_name; proxy_set_header Host $host; add_header Access-Control-Allow-Origin *; add_header Access-Control-Allow-Headers "accept, content-type"; } } [root@frontend-01 ~]# 3.

编译nginx status模块以及zabbix监控nginx状态

编译nginx status模块以及zabbix监控nginx状态

 Posted on September 11, 2015  |  2 minutes  |  374 words  |  Kenng zhang

背景原因：
因刚换工作,突然发现nginx status状态没有被监控,然后在准备添加nginx status的时候,发现之前同事在编译nginx的时候没有编译nginx status模块,可恶,常用的模块都不编译.主要两部分,
第一部分：编译nginx模块
第二部分：zabbix 监控nginx status,其实之前写过,稍微把监控方式优化了下。
一、nginx 编译模块
1.下载nginx安装包
