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上（example.com/installation/index.php）我注意到图像损坏（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”，但图像实际上位于“/installation/template/images/joomla.png”，这意味着我错过了“/ installation” /“part。

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;
}

取消注释“/etc/php/7.0/fpm/php.ini”中的“cgi.fix_pathinfo”行，并将值更改为0.

“/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，一旦我评论PATH_INFO部分，图像就会加载：

set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;

但我所有进一步尝试找出问题的根源都是不成功的，请帮我解决这个问题。

定义位置时，nginx按照外观顺序处理它们。 匹配文件的第一个规则被执行，其他规则被忽略。 这就是你首先放置一些安全性，接下来是静态资产，以及最后放置php的方法：

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

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)$ {

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。基本上，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，因此取消注释它不能解决问题。）
