WordPress is a free and open-source content management system (CMS). It’s the simplest and most popular solution to create your own website or blog. WordPress makes building a website accessible to anyone, even people who aren’t developers. With WordPress you can create any type of website such as blogs, eCommerce stores, portfolio websites, forums, resumes, business websites etc. In this step by step guide I will show you how to install WordPress on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest version of WordPress 6.8.2

     PMA_HOST: wordpress-db
     PMA_PORT: 3306
    restart: on-failure:5

Note: Before you paste the code above in the Web editor area below, change the values for WORDPRESS_DB_USER and MYSQL_USER. Type in your own username for both values; they have to be identical. marius is an example for a user.
Note: Before you paste the code above in the Web editor area below, change the value for WORDPRESS_DB_PASSWORD and MYSQL_PASSWORD. Type in your own password for both values; they have to be identical. mariuspassword is an example for a password. ⚠️Warning: Do NOT use a password with special characters that include the dollar symbol $.
Note: Before you paste the code above in the Web editor area below, change the value for WORDPRESS_DB_NAME and MYSQL_DATABASE. Type in your own database name for both values; they have to be identical. mariushosting_db is an example for a database name.
Note: Before you paste the code above in the Web editor area below, change the value for TZ. (Select your current Time Zone from this list.)
Note: Before you paste the code above in the Web editor area below, change the value numbers for user with your own UID and GID values. (Follow my step by step guide on how to do this.) 1026 is my personal UID value and 100 is my personal GID value. You have to type in your own values.

STEP 16

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

STEP 17

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

STEP 18

Go back to STEP 1 or you will deal with karma 🙂.

STEP 19

Please wait approximately 5 minutes for the installation to be completed or you will get a blank page with the following error message: Error establishing a database connection. Now open your browser and type in your HTTPS/SSL certificate like this https://wordpress.yourname.synology.me In my case it’s https://wordpress.mariushosting.synology.me If everything goes right, you will see the WordPress Installation Page. Choose your language then click Continue. Follow the instructions in the image below.

STEP 20

Type in your Site title, your own Username, your own Password and your own Email then click Install WordPress. Follow the instructions in the image below. ⚠️Warning: Username and Password in this area should be created now. ⚠️Do not confuse this Username and Password with the ones created at STEP 15.

STEP 21

Wait approximately 1 minute for the installation to be completed. Click Log in. Follow the instructions in the image below.

STEP 22

Type in your own Username and Password that you have previously created at STEP 20 then click Log in. Follow the instructions in the image below.

STEP 23

Your WordPress instance should look like this.

STEP 24

Go to File Station then open the wordpress folder. Follow the instructions in the image below.

STEP 25

Make sure you have installed Synology Text Editor as per the instructions at STEP 2. Double click on the wp-config.php file to open it. Follow the instructions in the image below.

STEP 26

Under the WORDPRESS_DEBUG line, copy and paste these two supplementary lines below. Click X to save the file. Follow the instructions in the image below.

define('WP_REDIS_HOST', 'wordpress-redis');
define('WP_REDIS_PORT', '6379');

STEP 27

On the WordPress left sidebar, click on Plugins, then Add Plugin. Search for Redis Object Cache. When you find the plugin named Redis Object Cache, click Install Now then Activate it. Follow the instructions in the image below.

Note: WordPress uses the MySQL/MariaDB database to cache internal application objects like breadcrumbs, menu items etc. which are very heavy to generate. A database handles queries for page requests, and causes increased load-times when your website is loaded intensively. Redis provides a caching mechanism that acts as an alternative to your MySQL/MariaDB database. If someone is visiting your WordPress website, the MySQL/MariaDB queries required to generate the entire page are served via Redis which caches the results. This results in blazing fast load times, comparable to static pages without Redis. When a user requests a WordPress page for the first time, a MySQL/MariaDB database query is performed on your Synology NAS server. Redis will cache this query, so when another user requests the same identical WordPress page, the results are provided from Redis, without the need to query the MySQL/MariaDB database again. So, in a few words, if the query is not cached in Redis, the results are provided by your MySQL/MariaDB database, which are then added to the Redis cache. Redis stores data in memory rather than on an HDD or SSD cache; its response time is faster than others when performing read and write operations.

STEP 28

After the Redis Object Cache plugin is installed, you will find it under the Settings menu. Click on Redis. Click Enable Object Cache. Follow the instructions in the image below.

STEP 29

After you click Enable Object Cache, the Status will say Connected. Follow the instructions in the image below. ⚠️Warning: If you accidentally click Flush Cache, your Redis host will be disconnected. To solve this issue, just restart the WordPress-REDIS container via Portainer.

STEP 30

phpMyAdmin is the graphical interface for the MariaDB database. It will help you connect to your database. Open your browser and type in http://Synology-ip-address:2500 Connect to your MariaDB using root as Username and rootpass as Password. Click Log in. Follow the instructions in the image below.

STEP 31

You can now download and back up your WordPress database without needing to install any backup plugin on your WordPress website. Warning: Do not expose the phpMyadmin instance to the Internet via Reverse Proxy. You can do it by using a strong password, but it’s not recommended to expose it. Keep it local.
Note: Find out how to backup your WordPress database using phpMyAdmin.
Note: Fix the error message: The phpMyAdmin configuration storage is not completely configured.

STEP 32

Find out how to add Email SMTP to your WordPress website so you can receive notifications via email.

STEP 33

Speed Up WordPress With Docker and Cron. Step by step guide on how to set up CRON in WordPress on your Synology NAS.

🆘TROUBLESHOOTING

⚠️Note: If you encounter permission issues and not all containers are starting, ensure that your current NAS user has Read/Write permissions for the Docker folder in Control Panel > User & Group > Select the current NAS user > Edit tab > Permissions tab. You can also try to add Everyone read/write permission to the db and redis folders at STEP 12 like this other article from STEP 5 to STEP 9.
