Running Drupal on Nginx with Varnish support can really improve your site performance. When looking for a fast and easy way to speed up your Drupal websites the steps below is a good place to start.
When dealing with high traffic Drupal websites or blogs you may want to implement some kind of caching mechanism to speed up the sites. One of the popular proxy servers that’s also a caching server is Varnish. If you want to build a fast Drupal sites with lots of web traffic, setting up Varnish as a proxy caching server will go a long way.
This brief tutorial is going to show students and new users how to setup Drupal on Ubuntu 16.04 LTS with Apache2, MariaDB, PHP 7.1 and Varnish proxy server support to speed up Drupal. After this setup, your Drupal site performance should improve a bit.
When you’re ready to get this working, follow the steps below:
Step 1: Install Apache2 HTTP Server
To install Apache2, run the commands below
sudo apt update sudo apt install apache2
with Apache2 installed, run the commands below to disable directory listing.
sudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/apache2/apache2.conf
Next, run the commands below to stop, start and enable Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service sudo systemctl start apache2.service sudo systemctl enable apache2.service
STEP 2: INSTALL VARNISH
Now that Apache2 is installed, run the commands below to install Varnish
sudo apt-get install varnish
After installing Varnish, the commands below can be used to start, stop and enable Varnish to always start up when the server boots
sudo systemctl stop varnish.service sudo systemctl start varnish.service sudo systemctl enable varnish.service
STEP 3: SWITCH APACHE2 DEFAULT PORT TO 8080
Since we want Varnish to listen for all traffic coming to port 80 which is Apache2 default port, let’s configure Apache2 to use another port number. You can open Apache2 default port configuration file at /etc/apache2/ports.conf and change the Listen value to 8080.
To quickly change the port run the commands below to open Apache2 default port configuration file.
sudo nano /etc/apache2/ports.conf
Then make sure the file has these lines. Save when done.
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf
Listen 127.0.0.1:8080
Next, open Apache2 default virtualhost config file.
sudo nano /etc/apache2/sites-available/000-default.conf
Then make the highlighted change below.
<VirtualHost 127.0.0.1:8080>
Save then file and exit.
After that, run the commands below to disable Apahce2 default site.
sudo a2dissite 000-default.conf
Then restart Apache2
sudo systemctl restart apache2.service
Now Apache2 default site is disabled.
Step 4: Install MariaDB Database Server
To install MariaDB run the commands below
sudo apt-get install mariadb-server mariadb-client
After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
After that, run the commands below to secure MariaDB server by creating a root password and disallowing remote root access.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Just press the Enter
- Set root password? [Y/n]: Y
- New password: Enter password
- Re-enter new password: Repeat password
- Remove anonymous users? [Y/n]: Y
- Disallow root login remotely? [Y/n]: Y
- Remove test database and access to it? [Y/n]: Y
- Reload privilege tables now? [Y/n]: Y
Restart MariaDB server
sudo systemctl restart mysql.service
Step 5: Install PHP 7.1 and Related Modules
Drupal also requires PHP. However, PHP 7.1 isn’t available on Ubuntu default repositories. in order to install it, you will have to get it from third-party repositories.
Run the commands below to add the below third party repository to upgrade to PHP 7.1
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.1
sudo apt update
Run the commands below to install PHP 7.1 and related modules.
sudo apt install php7.1 libapache2-mod-php7.1 php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-zip php7.1-curl
After install PHP 7.1, run the commands below to open Apache2 PHP default file.
sudo nano /etc/php/7.1/apache2/php.ini
Then make the changes on the following lines below in the file and save. The value below are great settings to apply in your environments.
file_uploads = On allow_url_fopen = On memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
Step 6: Create Drupal Database
Now that you’ve install all the packages are installed, run the commands below to create a blank Drupal database.
Logon to MariaDB database server
sudo mysql -u root -p
Then create a database called drupal
CREATE DATABASE drupal;
Create a database user called drupaluser with new password
CREATE USER 'drupaluser'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON drupal.* TO 'drupaluser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Step 7: Download Drupal Latest Release
Next, visit Drupal site and download the latest package. or run the commands below to download and extract Drupal content.
After downloading, run the commands below to extract the downloaded file and move it into a new Drupal root directory.
cd /tmp && cd /tmp && wget https://ftp.drupal.org/files/projects/drupal-8.4.2.tar.gz tar -zxvf drupal*.gz sudo mv drupal-8.4.2 /var/www/html/drupal
Then run the commands below to set the correct permissions for Drupal to function properly.
sudo chown -R www-data:www-data /var/www/html/drupal/ sudo chmod -R 755 /var/www/html/drupal/
Step 8: Configure Apache2 Drupal Site
Finally, configure Apache2 configuration file for Drupal. This file will control how users access Drupal content. Run the commands below to create a new configuration file called drupal.conf
sudo nano /etc/apache2/sites-available/drupal.conf
Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.
<VirtualHost *:8080> ServerAdmin admin@example.com DocumentRoot /var/www/html/drupal ServerName example.com ServerAlias www.example.com ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined <Directory /var/www/html/drupal/> Options FollowSymlinks AllowOverride All Require all granted </Directory> <Directory /var/www/html/drupal> RewriteEngine on RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] </Directory> </VirtualHost>
Save the file and exit.
Step 9: Enable the Drupal Site
After configuring the VirtualHost above, enable it by running the commands below
sudo a2ensite drupal.conf sudo a2enmod rewrite sudo a2enmod env sudo a2enmod dir sudo a2enmod mime
Step 10 : Restart Apache2
To load all the settings above, restart Apache2 by running the commands below.
sudo systemctl restart apache2.service
STEP 11: CONFIGURE VARNISH TO USE PORT 80
Now that port 80 is free, let’s configure Varnish to use that post instead. To assign port 80 to Varnish, run the commands below.
Varnish default configure file is location at /etc/default/varnish
Open it by running the commands below:
sudo nano /etc/default/varnish
Then look for the config block under Alternative 2 and make the highlighted changes as shown below.
## Alternative 2, Configuration with VCL
#
# Listen on port 6081, administration on localhost:6082, and forward to
# one content server selected by the vcl file, based on the request.
#
DAEMON_OPTS="-a :80 \
-T localhost:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,256m"
Save the file when you’re done.
Next, run the commands below to open the default.vcl file
sudo nano /etc/varnish/default.vcl
Then add the highlighted lines shown below under sub vcl_recv and sub vcl_backend_response
# Default backend definition. Set this to point to your content server.
backend default {
.host = "127.0.0.1";
.port = "8080";
}
sub vcl_recv {
if (req.url ~ "^/status\.php$" ||
req.url ~ "^/update\.php" ||
req.url ~ "^/install\.php" ||
req.url ~ "^/apc\.php$" ||
req.url ~ "^/admin" ||
req.url ~ "^/admin/.*$" ||
req.url ~ "^/user" ||
req.url ~ "^/user/.*$" ||
req.url ~ "^/users/.*$" ||
req.url ~ "^/info/.*$" ||
req.url ~ "^/flag/.*$" ||
req.url ~ "^.*/ajax/.*$" ||
req.url ~ "^.*/ahah/.*$" ||
req.url ~ "^/system/files/.*$") {
return (pass);
}
if (req.url ~ "(?i)\.(pdf|asc|dat|txt|doc|xls|ppt|tgz|csv|png|gif|jpeg|jpg|ico|swf|css|js)(\?.*)?$") {
unset req.http.Cookie;
}
if (req.http.Cookie) {
set req.http.Cookie = ";" + req.http.Cookie;
set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";");
set req.http.Cookie = regsuball(req.http.Cookie, ";(SESS[a-z0-9]+|SSESS[a-z0-9]+|NO_CACHE)=", "; \1=");
set req.http.Cookie = regsuball(req.http.Cookie, ";[^ ][^;]*", "");
set req.http.Cookie = regsuball(req.http.Cookie, "^[; ]+|[; ]+$", "");
if (req.http.Cookie == "") {
unset req.http.Cookie;
}
else {
return (pass);
}
}
sub vcl_backend_response {
if (bereq.url ~ "(?i)\.(css|js|jpg|jpeg|gif|png|ico)(\?.*)?$") {
unset beresp.http.set-cookie;
}
}
Save the file and close out.
When you’re done, restart Varnish and Apache2
sudo systemctl start apache2.service sudo systemctl start varnish.service
Next, run the commands below to start Varnish if it won’t start.
sudo /usr/sbin/varnishd -a :80 -b localhost:8080
After that, open your browser and browse to your domain name to launch WordPress configuration wizard.
And you should see WordPress setup wizard
Follow the wizard until you’ve successfully setup WordPress.
That’s it!
