WordPress – Blank pages and 200 http response on Debian using Nginx and php5

1 comment

1. Your problem can be caused by many factors:

   1. A poorly configured nginx (Read Configuring Nginx)

   2. A permission problem (Read step 5 of Configuring Nginx)

   3. A missing php module that you can find out enabling PHP error_reporting (Read Pages are still blank? Php error_reporting
   September)

   Configuring Nginx

   Nginx works a little differently from Apache and if you do not use a management panel, the procedure is a bit complicated.

   1. sudo apt-get install nginx php5-fpm mysql mysql-dev next activate mysql sudo mysql_install_dband run the setup script sudo /usr/bin/mysql_secure_installation

   2. Create a folder in /var/www with your site name (mkdir mess-affaires)

   3. go to /etc/nginx/sites-available and create a file with the same name as your domain (touch mess-affaires.xyz)

   4. Open your new file with an editor (nano mess-affaires.xyz) and add these lines:

   server {
       listen 80;
       root /var/www/mess-affaires;
       index index.html index.htm index.php;
       server_name www.mess-affaires.xyz mess-affaires.xyz;
       location / {
           try_files $uri $uri/ /index.php?q=$request_uri;
       }
       location ~ .php$ {
           fastcgi_split_path_info ^(.+.php)(/.+)$;
           fastcgi_pass unix:/run/php/php7.0-fpm.sock;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           fastcgi_index index.php;
           include fastcgi_params;
       }
   }
   

   4.1. After this you need to link it to your sites-enabled folder using:

   sudo ln -s /etc/nginx/sites-available/mess-affaires.xyz /etc/nginx/sites-enabled/mess-affaires.xyz
   

   Nginx set a default file for example in your sites-available, delete it to avoid the “conflicting server name error”:

   sudo rm /etc/nginx/sites-enabled/default
   

   4.2. Restart your nginx installation with sudo service nginx restart

   5. Set permission to your folder sudo chown -R www-data:www-data /var/www/mess-affaires/ and make sure that everyone is able to read your new files sudo chmod 755 /var/www o to your folder /var/www/mess-affaires and upload the wordpress installation, now you see the website.

   If you still don’t see anything, see the point 6

   6. If you do not see anything, go to your terminal and type:

   chmod -R 777 /var/www/mess-affaires
   

   Configuring mysql/phpmyadmin with nginx

   WordPress is a web application that require a mysql database, go to install it!

   1. sudo apt-get install phpmyadmin

   2. sudo ln -s /usr/share/phpmyadmin /usr/share/nginx/html

   3. Now we must now allow the mcrypt module in php sudo php5enmod mcrypt

   4. restart phpfpm sudo service php5-fpm restart

   5. visit http://YOUR_SERVER_IP/phpmyadmin, log-in and create a new database for your wordpress installation

   Pages are still blank? Set php error_reporting

   If your pages are still blank, enable php error_reporting.

   To do this you can try two ways:

   Set error_reporting from your php files

   Open your WordPress index.php and put these lines to the very top of your page (after

   error_reporting(E_ALL | E_STRICT);
   ini_set('display_errors', 1);
   

   Set error_reporting from php5-fpm.conf

   Open with an editor your php5-fpm-conf, try one of these directories:

   /etc/php-fpm.d/mydomain.conf
   /etc/php-fpm.conf
   

   If you sing my guide, you have not the native php installation but php5-fpm and you can configure your .conf file error params like this:

   ; enable display of errors
   php_flag[display_errors] = on
   php_flag[display_startup_errors] = on
   

   If you use a native php installation, set your config error_reporting like this:

   ; enable display of errors
   display_errors = On
   display_startup_errors = On
