Tutorial: Hosting a WordPress Blog with Amazon Linux

The following procedures will help you install, configure, and secure a WordPress blog on your Amazon Linux instance. This tutorial is a good introduction to using Amazon EC2 in that you have full control over a web server that hosts your WordPress blog, which is not typical with a traditional hosting service.

You are responsible for updating the software packages and maintaining security patches for your server. For a more automated WordPress installation that does not require direct interaction with the web server configuration, the AWS CloudFormation service provides a WordPress template that can also get you started quickly. For more information, see Getting Started in the AWS CloudFormation User Guide. If you’d prefer to host your WordPress blog on a Windows instance, see Deploying a WordPress Blog on Your Amazon EC2 Windows Instance in the Amazon EC2 User Guide for Windows Instances. If you need a high-availability solution with a decoupled database, see Deploying a High-Availability WordPress Website in the AWS Elastic Beanstalk Developer Guide.

Important

These procedures are intended for use with Amazon Linux. For more information about other distributions, see their specific documentation. Many steps in this tutorial do not work on Ubuntu instances. For help installing WordPress on an Ubuntu instance, see WordPress in the Ubuntu documentation.

Prerequisites

This tutorial assumes that you have launched an Amazon Linux instance with a functional web server with PHP and database (either MySQL or MariaDB) support by following all of the steps in Tutorial: Install a LAMP Web Server with the Amazon Linux AMI for Amazon Linux AMI or Tutorial: Install a LAMP Web Server on Amazon Linux 2 for Amazon Linux 2. This tutorial also has steps for configuring a security group to allow HTTP and HTTPS traffic, as well as several steps to ensure that file permissions are set properly for your web server. For information about adding rules to your security group, see Adding Rules to a Security Group.

We strongly recommend that you associate an Elastic IP address (EIP) to the instance you are using to host a WordPress blog. This prevents the public DNS address for your instance from changing and breaking your installation. If you own a domain name and you want to use it for your blog, you can update the DNS record for the domain name to point to your EIP address (for help with this, contact your domain name registrar). You can have one EIP address associated with a running instance at no charge. For more information, see Elastic IP Addresses.

If you don’t already have a domain name for your blog, you can register a domain name with Route 53 and associate your instance’s EIP address with your domain name. For more information, see Registering Domain Names Using Amazon Route 53 in the Amazon Route 53 Developer Guide.

Install WordPress

Connect to your instance, and download the WordPress installation package.

To download and unzip the WordPress installation package

  1. Download the latest WordPress installation package with the wget command. The following command should always download the latest release.
    [ec2-user ~]$ wget https://wordpress.org/latest.tar.gz
  2. Unzip and unarchive the installation package. The installation folder is unzipped to a folder called wordpress.
    [ec2-user ~]$ tar -xzf latest.tar.gz

To create a database user and database for your WordPress installation

Your WordPress installation needs to store information, such as blog post entries and user comments, in a database. This procedure helps you create a database for your blog and a user that is authorized to read and save information to that database.

  1. Start the database server.
    • Amazon Linux AMIsudo service mysqld start
    • Amazon Linux 2sudo systemctl start mariadb
  2. Log in to the database server as the root user. Enter your database root password when prompted; this may be different than your root system password, or it may even be empty if you have not secured your database server.

    Important

    If you have not secured your database server yet, it is very important that you do so. For more information, see To secure the database server.

    [ec2-user ~]$ mysql -u root -p
  3. Create a user and password for your MySQL database. Your WordPress installation uses these values to communicate with your MySQL database. Enter the following command, substituting a unique user name and password.
    CREATE USER 'wordpress-user'@'localhost' IDENTIFIED BY 'your_strong_password';

    Make sure that you create a strong password for your user. Do not use the single quote character ( ‘ ) in your password, because this will break the preceding command. For more information about creating a secure password, go to http://www.pctools.com/guides/password/. Do not reuse an existing password, and make sure to store this password in a safe place.

  4. Create your database. Give your database a descriptive, meaningful name, such as wordpress-db.

    Note

    The punctuation marks surrounding the database name in the command below are called backticks. The backtick (`) key is usually located above the Tab key on a standard keyboard. Backticks are not always required, but they allow you to use otherwise illegal characters, such as hyphens, in database names.

    CREATE DATABASE `wordpress-db`;
  5. Grant full privileges for your database to the WordPress user that you created earlier.
    GRANT ALL PRIVILEGES ON `wordpress-db`.* TO "wordpress-user"@"localhost";
  6. Flush the database privileges to pick up all of your changes.
    FLUSH PRIVILEGES;
  7. Exit the mysql client.
    exit

To create and edit the wp-config.php file

The WordPress installation folder contains a sample configuration file called wp-config-sample.php. In this procedure, you copy this file and edit it to fit your specific configuration.

  1. Copy the wp-config-sample.php file to a file called wp-config.php. This creates a new configuration file and keeps the original sample file intact as a backup.
    [ec2-user wordpress]$ cp wordpress/wp-config-sample.php wordpress/wp-config.php
  2. Edit the wp-config.php file with your favorite text editor (such as nano or vim) and enter values for your installation. If you do not have a favorite text editor, nano is much easier for beginners to use.
    [ec2-user wordpress]$ nano wordpress/wp-config.php
    1. Find the line that defines DB_NAME and change database_name_here to the database name that you created in Step 4 of To create a database user and database for your WordPress installation.
      define('DB_NAME', 'wordpress-db');
    2. Find the line that defines DB_USER and change username_here to the database user that you created in Step 3 of To create a database user and database for your WordPress installation.
      define('DB_USER', 'wordpress-user');
    3. Find the line that defines DB_PASSWORD and change password_here to the strong password that you created in Step 3 of To create a database user and database for your WordPress installation.
      define('DB_PASSWORD', 'your_strong_password');
    4. Find the section called Authentication Unique Keys and Salts. These KEY and SALT values provide a layer of encryption to the browser cookies that WordPress users store on their local machines. Basically, adding long, random values here makes your site more secure. Visit https://api.wordpress.org/secret-key/1.1/salt/ to randomly generate a set of key values that you can copy and paste into your wp-config.php file. To paste text into a PuTTY terminal, place the cursor where you want to paste the text and right-click your mouse inside the PuTTY terminal.For more information about security keys, go to http://codex.wordpress.org/Editing_wp-config.php#Security_Keys.

      Note

      The values below are for example purposes only; do not use these values for your installation.

      define('AUTH_KEY',         ' #U$$+[RXN8:b^-L 0(WU_+ c+WFkI~c]o]-bHw+)/Aj[wTwSiZ<Qb[mghEXcRh-');
      define('SECURE_AUTH_KEY',  'Zsz._P=l/|y.Lq)XjlkwS1y5NJ76E6EJ.AV0pCKZZB,*~*r ?6OP$eJT@;+(ndLg');
      define('LOGGED_IN_KEY',    'ju}qwre3V*+8f_zOWf?{LlGsQ]Ye@2Jh^,8x>)Y |;(^[Iw]Pi+LG#A4R?7N`YB3');
      define('NONCE_KEY',        'P(g62HeZxEes|LnI^i=H,[XwK9I&[2s|:?0N}VJM%?;v2v]v+;+^9eXUahg@::Cj');

      define('SECURE_AUTH_SALT', 'd!uRu#}+q#{f$Z?Z9uFPG.${+S{n~1M&%@~gL>U>NV<zpD-@2-Es7Q1O-bp28EKv');
      define('LOGGED_IN_SALT',   ';j{00P*owZf)kVD+FVLn-~ >.|Y%Ug4#I^*LVd9QeZ^&XmK|e(76miC+&W&+^0P/');
      define('NONCE_SALT',       '-97r*V/cgxLmp?Zy4zUU4r99QQ_rGs2LTd%P;|_e1tS)8_B/,.6[=UK<J_y9?JWG');
    5. Save the file and exit your text editor.

To install your WordPress files under the Apache document root

  1. Now that you’ve unzipped the installation folder, created a MySQL database and user, and customized the WordPress configuration file, you are ready to copy your installation files to your web server document root so you can run the installation script that completes your installation. The location of these files depends on whether you want your WordPress blog to be available at the actual root of your web server (for example,my.public.dns.amazonaws.com) or in a subdirectory or folder under the root (for example,my.public.dns.amazonaws.com/blog).
  2. If you want WordPress to run at your document root, copy the contents of the wordpress installation directory (but not the directory itself) as follows:
    [ec2-user ~]$ cp -r wordpress/* /var/www/html/
  3. If you want WordPress to run in an alternative directory under the document root, first create that directory, and then copy the files to it. In this example, WordPress will run from the directory blog:
    [ec2-user ~]$ mkdir /var/www/html/blog
    [ec2-user ~]$ cp -r wordpress/* /var/www/html/blog/

Important

For security purposes, if you are not moving on to the next procedure immediately, stop the Apache web server (httpd) now. After you move your installation under the Apache document root, the WordPress installation script is unprotected and an attacker could gain access to your blog if the Apache web server were running. To stop the Apache web server, enter the command sudo service httpd stop. If you are moving on to the next procedure, you do not need to stop the Apache web server.

To allow WordPress to use permalinks

WordPress permalinks need to use Apache .htaccess files to work properly, but this is not enabled by default on Amazon Linux. Use this procedure to allow all overrides in the Apache document root.

  1. Open the httpd.conf file with your favorite text editor (such as nano or vim). If you do not have a favorite text editor, nano is much easier for beginners to use.
    [ec2-user wordpress]$ sudo vim /etc/httpd/conf/httpd.conf
  2. Find the section that starts with <Directory "/var/www/html">.
    <Directory "/var/www/html">
        #
        # Possible values for the Options directive are "None", "All",
        # or any combination of:
        #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
        #
        # Note that "MultiViews" must be named *explicitly* --- "Options All"
        # doesn't give it to you.
        #
        # The Options directive is both complicated and important.  Please see
        # http://httpd.apache.org/docs/2.4/mod/core.html#options
        # for more information.
        #
        Options Indexes FollowSymLinks
    
        #
        # AllowOverride controls what directives may be placed in .htaccess files.
        # It can be "All", "None", or any combination of the keywords:
        #   Options FileInfo AuthConfig Limit
        #
        AllowOverride None
    
        #
        # Controls who can get stuff from this server.
        #
        Require all granted
    </Directory>
  3. Change the AllowOverride None line in the above section to read AllowOverride All.

    Note

    There are multiple AllowOverride lines in this file; be sure you change the line in the <Directory "/var/www/html"> section.

    AllowOverride All
  4. Save the file and exit your text editor.

To fix file permissions for the Apache web server

Some of the available features in WordPress require write access to the Apache document root (such as uploading media though the Administration screens). If you have not already done so, apply the following group memberships and permissions (as described in greater detail in the LAMP web server tutorial).

  1. Change the file ownership of /var/www and its contents to the apache user.
    [ec2-user wordpress]$ sudo chown -R apache /var/www
  2. Change the group ownership of /var/www and its contents to the apache group.
    [ec2-user wordpress]$ sudo chgrp -R apache /var/www
  3. Change the directory permissions of /var/www and its subdirectories to add group write permissions and to set the group ID on future subdirectories.
    [ec2-user wordpress]$ sudo chmod 2775 /var/www
  4. Recursively change the file permissions of /var/www and its subdirectories to add group write permissions.
    [ec2-user wordpress]$ find /var/www -type d -exec sudo chmod 2775 {} \;
  5. Restart the Apache web server to pick up the new group and permissions.
    • Amazon Linux AMIsudo service httpd restart
    • Amazon Linux 2sudo systemctl restart httpd

To run the WordPress installation script

  1. Use the chkconfig command to ensure that the httpd and database services start at every system boot.
    • Amazon Linux AMIsudo chkconfig enable httpd && sudo chkconfig enable mysql
    • Amazon Linux 2sudo systemctl enable httpd && sudo systemctl enable mariadb
  2. Verify that the database server is running.
    • Amazon Linux AMIsudo service mysqld status
    • Amazon Linux 2sudo systemctl status mariadb

    If the database service is not running, start it.

    • Amazon Linux AMIsudo service mysqld start
    • Amazon Linux 2sudo systemctl start mariadb
  3. Verify that your Apache web server (httpd) is running.
    • Amazon Linux AMIsudo service httpd status
    • Amazon Linux 2sudo systemctl status httpd

    If the httpd service is not running, start it.

    • Amazon Linux AMIsudo service httpd start
    • Amazon Linux 2sudo systemctl start httpd
  4. In a web browser, enter the URL of your WordPress blog (either the public DNS address for your instance, or that address followed by the blog folder). You should see the WordPress installation screen.
    http://my.public.dns.amazonaws.com
    <br /><br />
                        WordPress installation screen<br /><br />
  5. Enter the remaining installation information into the WordPress installation wizard.
    Field Value
    Site Title Enter a name for your WordPress site.
    Username Enter a name for your WordPress administrator. For security purposes, you should choose a unique name for this user, because it will be more difficult to exploit than the default user name,admin.
    Password Enter a strong password, and then enter it again to confirm. Do not reuse an existing password, and make sure to store this password in a safe place.
    Your E-mail Enter the email address you want to use for notifications.
  6. Click Install WordPress to complete the installation.

Congratulations, you should now be able to log into your WordPress blog and start posting entries.

Next Steps

After you have tested your initial WordPress blog, consider updating its configuration.

Use a Custom Domain Name

If you have a domain name associated with your EC2 instance’s EIP address, you can configure your blog to use that name instead of the EC2 public DNS address. For more information, see http://codex.wordpress.org/Changing_The_Site_URL.

Configure Your Blog

You can configure your blog to use different themes and plugins to offer a more personalized experience for your readers. However, sometimes the installation process can backfire, causing you to lose your entire blog. We strongly recommend that you create a backup Amazon Machine Image (AMI) of your instance before attempting to install any themes or plugins so you can restore your blog if anything goes wrong during installation. For more information, see Creating Your Own AMI.

Increase Capacity

If your WordPress blog becomes popular and you need more compute power or storage, consider the following steps:

Learn More about WordPress

For information about WordPress, see the WordPress Codex help documentation at http://codex.wordpress.org/. For more information about troubleshooting your installation, go to http://codex.wordpress.org/Installing_WordPress#Common_Installation_Problems.

For information about keeping your WordPress blog up-to-date, go to http://codex.wordpress.org/Updating_WordPress.

Help! My Public DNS Name Changed and now my Blog is Broken

Your WordPress installation is automatically configured using the public DNS address for your EC2 instance. If you stop and restart the instance, the public DNS address changes (unless it is associated with an Elastic IP address) and your blog will not work anymore because it references resources at an address that no longer exists (or is assigned to another EC2 instance). A more detailed description of the problem and several possible solutions are outlined in http://codex.wordpress.org/Changing_The_Site_URL.

If this has happened to your WordPress installation, you may be able to recover your blog with the procedure below, which uses the wp-cli command line interface for WordPress.

To change your WordPress site URL with the wp-cli

  1. Connect to your EC2 instance with SSH.
  2. Note the old site URL and the new site URL for your instance. The old site URL is likely the public DNS name for your EC2 instance when you installed WordPress. The new site URL is the current public DNS name for your EC2 instance. If you are not sure of your old site URL, you can use curl to find it with the following command.
    [ec2-user ~]$ curl localhost | grep wp-content

    You should see references to your old public DNS name in the output, which will look like this (old site URL in red):

    <script type='text/javascript' src='http://ec2-52-8-139-223.us-west-1.compute.amazonaws.com/wp-content/themes/twentyfifteen/js/functions.js?ver=20150330'></script>
  3. Download the wp-cli with the following command.
    [ec2-user ~]$ curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
  4. Search and replace the old site URL in your WordPress installation with the following command. Substitute the old and new site URLs for your EC2 instance and the path to your WordPress installation (usually/var/www/html or /var/www/html/blog).
    [ec2-user ~]$ php wp-cli.phar search-replace 'old_site_url' 'new_site_url' --path=/path/to/wordpress/installation --skip-columns=guid
  5. In a web browser, enter the new site URL of your WordPress blog to verify that the site is working properly again. If it is not, see http://codex.wordpress.org/Changing_The_Site_URL and http://codex.wordpress.org/Installing_WordPress#Common_Installation_Problems for more information.
