Debian 9 + PHP7.0-FPM + NGINX 1.10.3-1 path_info 问题

Question

我正在使用 DigitalOcean Debian 9 + PHP 7.0 + NGINX 1.10.3-1 并尝试安装 Joomla！ CMS，但在第一个安装屏幕（示例。com/installation/index。php）我注意到一个损坏的图像（这是 Joomla 徽标），它看起来像这样：

该图像的

img src 属性包含“/template/images/joomla.png”，但该图像实际上位于“/installation/template/images/joomla.png”，这意味着我缺少“/installation /”部分。

这是我的 PHP:

的 nginx conf 部分

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}

“/etc/php/7.0/fpm/php.ini”处的 "cgi.fix_pathinfo" 行取消注释，值更改为 0。

并且“/snippets/fastcgi-php.conf”文件包含以下内容：

# regex to split $uri to $fastcgi_script_name and $fastcgi_path
fastcgi_split_path_info ^(.+\.php)(/.+)$;

# Check that the PHP script exists before passing it
try_files $fastcgi_script_name =404;

# Bypass the fact that try_files resets $fastcgi_path_info
# see: http://trac.nginx.org/nginx/ticket/321
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;

fastcgi_index index.php;
include fastcgi.conf;

我注意到在我评论 PATH_INFO 部分后图像正在加载：

set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;

但是我进一步尝试找出问题的根源都没有成功，请帮我解决这个问题。

当您定义位置时，nginx 会按照出现的顺序处理它们。与文件匹配的第一条规则被执行，其他规则被忽略。这就是您如何将一些安全性放在首位，然后是静态资产，最后是 php：

server {
listen 80;
server_name  example.com;
root   /full/path/to/your/joomla/root/directory;

# allow letsencrypt
location ~ /.well-known/acme-challenge {
allow all;
access_log off;
log_not_found off;
}

# handle some security and logs
location = /favicon.ico {
access_log off;
log_not_found off;
}

location = /robots.txt {
allow all;
access_log off;
log_not_found off;
}

# Deny access to htaccess and other hidden files
location ~ /\. {
deny  all;
access_log off;
log_not_found off;
}

# handle static xml files
location ~* \.(xml)$ {
access_log off;
log_not_found off;
add_header Pragma no-cache;
add_header Cache-Control "no-cache, no-store, must-revalidate, post-check=0, pre-check=0";
gzip off;
}

# include in each host for static content to run with cache and without logs, with CORS enabled (for fonts)
location ~* \.(jpg|jpeg|gif|png|bmp|css|js|ico|txt|pdf|swf|flv|mp4|mp3|eot|ttf|svg|woff|woff2)$ {
add_header Access-Control-Allow-Origin *;
add_header  Cache-Control "public";
access_log off;
log_not_found off;
tcp_nopush on;

我们的一位客户遇到了同样的问题，我们在 this post 中解释了如何修复它。本质上，您的 try_files 行不正确。

顺便说一句，cgi.fix_pathinfo 必须设置为 1，而不是零（默认为 0，因此取消注释并不能解决问题。）
