錯誤記錄檔
裝好 nginx-1.0.5 與 php-5.3.6(php-fpm) 迫不及待的測試 info.php(<?php phpinfo(); ?>),但是只返回了空白頁,什麼也沒有輸出,以下是錯誤記錄檔。

分析
1 使用firefox 瀏覽 http://192.168.5.87/info.php 測試頁返回空白頁,什麼都沒有。
2 使用curl 測試 http://192.168.5.87/info.php 測試頁提示404沒找到。
# curl -I http://192.168.5.87/info.php
HTTP/1.1 404 Not Found
Server: nginx/1.0.5
Date: Mon, 01 Aug 2011 06:54:46 GMT
Content-Type: text/html
Connection: keep-alive
X-Powered-By: PHP/5.3.6
3 使用firefox 瀏覽 http://192.168.5.87/index.html
4 靜態頁面的index.html 是可以訪問的,而動態info.php確是404 找不到,為什麼會這樣那?index.html 檔案目錄是nginx預設安裝目錄 /usr/local/nginx/html,而
info.php 我把它放到了 /data/web 下 是不是這個原因 ?看下nginx.conf配置文檔
server {
listen 80;
server_name localhost;
location / {
index index.html index.htm;
root html;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
}
過程
嘗試更改下
location ~ \.php$ {
root /data/web;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
nginx -t && nginx -s reload
測試訪問仍然不行
google
再次更改
location ~ \.php$ {
root /data/web;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/web$fastcgi_script_name;
include fastcgi_params;
}
nginx -t && nginx -s reload
測試一下
[root@me zongm]# curl -I http://192.168.5.87/info.php
HTTP/1.1 200 OK
Server: nginx/1.0.5
Date: Mon, 01 Aug 2011 08:34:17 GMT
Content-Type: text/html
Connection: keep-alive
X-Powered-By: PHP/5.3.6
firefox 測試ok!
總結
問題還是在配置文檔上,估計不少朋友會遇到php 輸出空白頁什麼也不顯示,
主要是nginx 的 root 指令 或者 fastcgi_param 指令 配置出了問題詳細的文檔請參考這裡!
再看下nginx.conf配置文檔,
server{
location / {
index index.html index.htm;
root html;
}
location = /50x.html {
root html
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
}
1 發現除了location ~ \.php$以外,每個location 下都有個root 指令用於載入web檔案根目錄,預設都是 /usr/local/nginx/html,第一個錯誤是沒有在 location ~ \.php$ 添加web檔案根目錄
root /data/web;
或者在server 欄位下加入一個 root 例如
server {
.........
root /data/web;
.........
}
2 參考這裡知道了 PHP使用fastcgi_param 指令的 SCRIPT_FILENAME參數決定需要執行哪個指令碼,所以這個位置也要改成
fastcgi_param SCRIPT_FILENAME /data/web$fastcgi_script_name;
