## proxy_pass指令 1. 由http_proxy模塊提供(ngx_http_proxy_module); 2. 默認已被編譯進nginx; 3. 禁用須通過--without-http_proxy_module; ## proxy_pass語法結構 語法: ``` proxy_pass URL; ``` URL參數規則: 1. URL開頭必須以http或https開頭; 2. URL中可以攜帶變量; 3. URL中是否帶URI,會影響發往上游請求的URL; 默認值: ``` 無 ``` 上下文: ``` location | if | limit_except ``` 示例: ``` proxy_pass http://127.0.0.1:8080; proxy_pass http://127.0.0.1:8090/proxy; ``` ## 實例 1. 先配置一臺應用服務器,可訪問的資源是192.168.33.10/proxy; 2. 本地nginx配置: ``` upstream back_end{ server 192.168.33.10 weight=3 max_conns=1000 fail_timeout=10s max_fails=2; keepalive 32; keepalive_requests 50; keepalive_timeout 30s; } server { listen 80; server_name website.com; charset utf-8; root html; location /pass { proxy_pass http://back_end/proxy; //proxy_pass的URL必須是http或https開頭的,back_end對應上面配置的upstream上游服務器名稱,因為訪問的URI是/proxy,所以后面要加上; } ``` 3. 結果:訪問成功
