6. Publish your WordPress site to the public network

If you have not installed cpolar, please refer to the first article to install and configure cpolar.

Before we use cpolar to publish WordPress to the public network, we usually need to do two things:

Install relative URL plugin

You have to make sure WordPress publishes as relative URLs. You can do this by installing one of the following plugins

In this example, we install Relative URLthe plugin:

Enter in the keyword search bar and press Relative URLEnter

After finding the plug-in, click 现在安装the button
When the installation is successful, click 启用the button to activate the plug-in.

Modify config.php configuration

You have to make sure WordPress understands that it is meant to be served through the tunnel hostname. You can configure WordPress by modifying wp-config.php to include the following line:

define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']);

Modify wp-config.php file

sudo nano /var/www/html/wp-config.php

After configuration, it looks like this:

Now, our blog site can be accessed normally by the public network! Let's see the effect:

7. Support friend link style

It is recommended that you change your permalink settings to make your URLs more user-friendly.

To do this, log into WordPress and go to 仪表盘.

Go to 设置, then go to 固定链接.

Select 文章名an option and click 保存更改.

You need to enable Apache's rewrite module:

sudo a2enmod rewrite

You also need to tell the web host serving the site to allow override requests.

Edit the virtual host's Apache configuration file:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the following lines after line 1.

<Directory "/var/www/html">
    AllowOverride All
</Directory>

Make sure it is in as shown below:

<VirtualHost *:80>
    <Directory "/var/www/html">
        AllowOverride All
    </Directory>
    ...

Save the file and exit.
Restart Apache.

sudo service apache2 restart

8. Customized themes

WordPress is very customizable. By clicking on your site name in the WordPress banner at the top of the page (when you are logged in) you will be taken to the dashboard. From there, you can change themes, add pages and posts, edit menus, add plugins, and more. This is just a taster for setting up some fun stuff on the Raspberry Pi's web server.

Next, let’s try changing a theme.

WordPress Dashboard–>Appearance–>Theme

Click Popular, choose a theme you like, and click 安装the button

After the theme is installed successfully, click 启用the button.
Let's reopen the site and see the effect:

Now that your site has been built, you can further experience more themes and explore slowly.
