如何配置nginx重写规则以使CakePHP在CentOS上运行？

Question

Hi somebody please help me out, I'm trying to setup a cakephp environment on a Centos server running Nginx with Fact CGI. I already have a wordpress site running on the server and a phpmyadmin site so I have PHP configured correctly.

My problem is that I cannot get the rewrite rules setup correct in my vhost so that cake renders pages correctly ie with styling and so on. I've googled as much as possible and the main consensus from the sites like the one listed below is that I need to have the following rewrite rule in place

location / {
          root   /var/www/sites/somedomain.com/current;
          index  index.php index.html;

          # If the file exists as a static file serve it 
          # directly without running all
          # the other rewrite tests on it
          if (-f $request_filename) { 
            break; 
          }
          if (!-f $request_filename) {
            rewrite ^/(.+)$ /index.php?url=$1 last;
            break;
          }
        }

http://blog.getintheloop.eu/2008/4/17/nginx-engine-x-rewrite-rules-for-cakephp

problem is these rewrite assume you run cake directly out of the webroot which is not what I want to do. I have a standard setup for each site ie one folder per site containing the following folders log, backup, private and public. Public being where nginx is looking for its files to serve but I have cake installed in private with a symlink in public linking back to /private/cake/

this is my vhost

server {
            listen      80;
            server_name app.domain.com;

            access_log /home/public_html/app.domain.com/log/access.log;
            error_log /home/public_html/app.domain.com/log/error.log;

  #configure Cake app to run in a sub-directory
  #Cake install is not in root, but elsewhere and configured
  #in APP/webroot/index.php**

                location /home/public_html/app.domain.com/private/cake {
                index index.php;

    if (!-e $request_filename) {
        rewrite ^/(.+)$ /home/public_html/app.domain.com/private/cake/$1 last;
        break;
    }
}

                location /home/public_html/app.domain.com/private/cake/ {
                index index.php;

    if (!-e $request_filename) {
        rewrite ^/(.+)$ /home/public_html/app.domain.com/public/index.php?url=$1 last;
        break;
        }
}

         # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME /home/public_html/app.domain.com/private/cake$fastcgi_script_name;
            include        /etc/nginx/fastcgi_params;
        }

 }

Now like I said I can see the main index.php of cake and have connected it to my DB but this page is without styling so before I proceed any further I would like to configure it correctly. What am I doing wrong?

Thanks seanl

Answer 1

At a glance, your problem might be that you are not pointing nginx to the webroot of your app. Deploying to the root cake folder is really not the way to go under any web-server.

The following is a complete server-block I use running Cake apps. In reality I only have the first four lines and then include the rest from a separate file "cakephp.inc".

A note on the line "fastcgi_param SERVER_NAME $host;". This is because some of my apps use $_SERVER['SERVER_NAME'] and it does not have the same meaning in nginx as in Apache. If youe server has several server_name(s) defined nginx will always pass the first one to php.

server { 
    server_name  cakeapp.example.com;
    root   /var/www/vhosts/cake/app/webroot;
    access_log  /var/log/nginx/cakeapp.access.log;
    error_log   /var/log/nginx/cakeapp.error.log;

    listen       80;
    rewrite_log on;

    # rewrite rules for cakephp
    location / {
        index  index.php index.html;

        # If the file exists as a static file serve it 
        # directly without running all
        # the other rewite tests on it
        if (-f $request_filename) { 
            break; 
        }
        if (!-f $request_filename) {
            rewrite ^/(.+)$ /index.php?url=$1 last;
            break;
        }
    }

    location ~* \favicon.ico$ {
        expires 6m;
    }
    location ~ ^/img/ { 
        expires 7d; 
    } 

    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
        fastcgi_param SERVER_NAME $host;
    }

    location ~ /\.ht {
        deny  all;
    }
}

There's now official documentation on this issue , which I used and confirmed works.

The documentation states:

server {
  listen   80;
  server_name www.example.com;
  rewrite ^(.*) http://example.com$1 permanent;
}

server {
  listen   80;
  server_name example.com;

  # root directive should be global
  root   /var/www/example.com/public/app/webroot/;
  index  index.php;

  access_log /var/www/example.com/log/access.log;
  error_log /var/www/example.com/log/error.log;

  location / {
    try_files $uri $uri/ /index.php?$args;
  }

  location ~ \.php$ {
    try_files $uri =404;
    include /etc/nginx/fastcgi_params;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index   index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }
}

Answer 3

I got this working:

root DIR/app/webroot/;
location / {
    index index.php index.html;
    rewrite ^/$ /index.php?url=/;
    if (!-e $request_filename) {
        rewrite ^(/.*)$ /index.php?url=$1 last;
    }
}

and then of course handlers for php and stuff...

Answer 4

It is not advisable to use 'IF' blocks inside a 'location' block.

Here is a more natural way to achieve the same, using regex locations.

In this example, CakePHP 2.x is the root app on a vhost (skipping common stuff like server_name , logs etc):

 root   /path/to/cakephp-2.x_root/app/webroot;
 index index.php;

 location ~ .+\.php$ {
        try_files $uri =404; #handle requests for missing .php files
        include        fastcgi_params;
        fastcgi_pass   127.0.0.1:7001; #the FPM pool port
    }


    location ~ ^/(.*) {
        try_files $uri $uri/ /index.php?url=$1&$args;
    }

Note that the .php location block is BEFORE the / location block. That's important because with regex locations, they are searched until the first match.

If you need to make it run in a sublocation, eg http://www.example.com/something/ , here is how I managed to do it. First I had to do a symlink to trick nginx: extract cakephp-2.x somewhere, then in 'app/webroot' create a symlink to itself with the same name as the sublocation, eg 'ln -s ../webroot something' .

Then the following config works to access cackephp under /something/:

    location ~ ^/something/.+\.php$ {
        try_files $uri =404; #handle requests for missing .php files
        root /path/to/cakephp-2.x_root/app/webroot;
        include        fastcgi_params;
        fastcgi_pass   127.0.0.1:7001; #the FPM pool port
    }

    location ~ ^/something(?:/)(.*) {
        root /path/to/cakephp-2.x_root/app/webroot;
        index index.php;
        try_files $uri $uri/ /something/index.php?url=$1&$args;
    }

Symlinking can probably be avoided by using 'alias' istead of 'root' but I could not figure out how.

Answer 5

I had a bunch of issues setting up a CakePHP site that was running an older version of CakePHP 1.2 - going by the date of this post it might be around the time. I recently blogged about it and simply suggest upgrading or installing a fresh version of the Cake library and all problems went away.

Answer 6

Please use below code in

vi /etc/nginx/sites-available/domainname.com

server { 
server_name  cakeapp.example.com;
root   /var/www/vhosts/cake/app/webroot;
access_log  /var/log/nginx/cakeapp.access.log;
error_log   /var/log/nginx/cakeapp.error.log;

listen       80;
rewrite_log on;

# rewrite rules for cakephp
location / {
    index  index.php index.html;

    # If the file exists as a static file serve it 
    # directly without running all
    # the other rewite tests on it
    if (-f $request_filename) { 
        break; 
    }
    if (!-f $request_filename) {
        rewrite ^/(.+)$ /index.php?url=$1 last;
        break;
    }
}

location ~* \favicon.ico$ {
    expires 6m;
}
location ~ ^/img/ { 
    expires 7d; 
} 

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include /etc/nginx/fastcgi_params;
    fastcgi_param SERVER_NAME $host;
}

location ~ /\.ht {
    deny  all;
}

}

Its working for me.
