具有路由重写的Nginx嵌套位置

Question

我想在一个站点中将几个专用路由嵌套到可能不同名的特定目录。我不知道如何重写它用于try_files的路径。

server {           
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/default;
index index.html;
server_name _;
if ($bad_referer) {
return 444;
}
location / {
try_files $uri $uri/ =404;
}
location /postfixadmin/ {
access_log /var/log/nginx/postfixadmin/access.log;
error_log /var/log/nginx/postfixadmin/error.log;
root /var/www/postfixadmin/;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php;

location ~ .php$ {
include fastcgi.conf;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}
location ~* .(css|js|gif|jpe?g|png|woff|woff2|ttf|eot|svg|ico)$ {
expires 168h;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
}
location /email/ {
#access_log /var/log/nginx/roundcube/access.log;
#error_log /var/log/nginx/roundcube/error.log;
root /var/www/roundcube/;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php;
location ~ .php$ {
include fastcgi.conf;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}
location ~* .(css|js|gif|jpe?g|png|woff|woff2|ttf|eot|svg|ico)$ {
expires 168h;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
}
}

当我导航到www.site.com/email时，我会收到一个404，我认为这是因为它在寻找不存在的/var/www/roundcube/email/index.php。我需要做什么来重写try_files之前的文件路径？

Answer 1

我找到了解决方案，结果证明它相当简单。使用alias而不是root只使用字符串中与location匹配的部分之后的部分，所以我在正确的目录中查找。另一个问题是PHP没有被传递正确的脚本名称，所以它仍然在错误的地方查找。解决方案是通过fastcgi_param SCRIPT_FILENAME $request_filename;。我也能够去掉try_files部分，尽管我不能100%确定原因。

以下是有效的解决方案：

server {           
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/default;
index index.html;
server_name _;
if ($bad_referer) {
return 444;
}
try_files $uri $uri/ =404;
location /postfixadmin {
alias /var/www/postfixadmin/;
index index.php index.html index.htm;
location ~ /postfixadmin/.+.php$ {
include fastcgi.conf;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}
location ~* .(css|js|gif|jpe?g|png|woff|woff2|ttf|eot|svg|ico)$ {
expires 168h;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
}
location /email {
alias /var/www/roundcube/;
index index.php index.html index.htm;
location ~ /email/.+.php$ {
include fastcgi.conf;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}
location ~* .(css|js|gif|jpe?g|png|woff|woff2|ttf|eot|svg|ico)$ {
expires 168h;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
}
}
