HHVM退回到PHP-FPM

Question

我正在與HHVM上nginx的PHP應用程序爲主要和PHP-FPM作爲備份

這是我關於PHP處理

location ~ \.(hh|php)$ { 
    fastcgi_intercept_errors on; 
    error_page 500 501 502 503 = @fallback; 

    try_files $uri =404; 

    fastcgi_split_path_info ^(.+\.php)(/.+)$; 

    fastcgi_keep_conn on; 

    include   fastcgi_params; 
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
    fastcgi_param SERVER_NAME $host; 
    fastcgi_pass 127.0.0.1:9000; 
    } 

    location @fallback { 

    try_files $uri =404; 

    fastcgi_split_path_info ^(.+\.php)(/.+)$; 

    include   fastcgi_params; 
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
    fastcgi_param SERVER_NAME $host; 
    fastcgi_pass unix:/var/run/php5-fpm.sock; 

    } 

爲了測試Nginx的配置的配置，我停止了HHVM service.Normally，將請求傳遞給PHP-FPM，而應返回200，但我得到502錯誤如下：

12296#0: *17 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.34.235, server: stylep3.com, request: "GET/HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host:localhost 

難道我做錯了什麼在這裏

Answer 1

這是可行的更簡單的方法。

首先用hhvm和php-fpm定義一個上游作爲備份。

upstream fastcgi_server { 
    server unix:/var/run/hhvm/hhvm.sock; 
    server unix:/var/run/php-fpm-mysite.sock backup; 
} 

就用fastcgi_server好像是唯一的後端，與故障轉移工作nginx的交易，而不是你。

fastcgi_pass fastcgi_server; 

模塊上游文檔非常有啓發性。

彙總，你的榜樣應該是這樣的：

upstream php_backend { 
    server 127.0.0.1:9000; 
    server unix:/var/run/php5-fpm.sock backup; 
} 


server { 
# 
# other conf... 
# 

location ~ \.(hh|php)$ { 
    fastcgi_intercept_errors on; 

    try_files $uri =404; 

    fastcgi_split_path_info ^(.+\.php)(/.+)$; 

    fastcgi_keep_conn on; 

    include   fastcgi_params; 
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
    fastcgi_param SERVER_NAME $host; 
    fastcgi_pass php_backend; 
    } 

}
