How to Configure a Free Domain HTTPS Certificate for a WordPress Blogging Site

In this article, YY will introduce to you how to configure HTTPS certificates for WordPress sites

Preconditions:

You already have a domain name of your own
- If not, please go to (Alibaba Cloud, Tencent Cloud, Xinwang, etc.) domain name provider.
Windows 7 or above operating system (this tutorial uses Windows 10 as an example)
WordPress installed
- If not, please refer to the previous tutorial.
cpolar already installed
- If not, please refer to "How to download and install the cpolar intranet penetration tool in Win system?" " Tutorial.
A custom domain name tunnel has been configured
- If not, please refer to "How to configure the domain name purchased by myself for the WordPress blog site, and make it accessible from the public network?" "

In this example, assume that we already have our own domain name: bestexpresser.com, and have configured dev.bestexpresser.coma custom domain name according to "Tutorial 5". Next, we will apply for a domain name certificate, configure it in cpolar, and let our site support the HTTPS protocol.

Step 1 Apply for a free domain name HTTPS certificate

If your domain name is purchased from Alibaba Cloud or Tencent Cloud, usually the platform can apply for a free subdomain certificate. In this example, we can apply for a dev.bestexpresser.com free domain name HTTPS certificate on Alibaba Cloud. For details, please refer to: "How to apply for Alibaba Cloud's free domain name HTTPS certificate for a blog website"

Step 2 Configure the HTTP certificate to the configuration file of cpolar

When we get the HTTPS certificate file package of the website, there are two files in it, one is the site certificate file, and the other is the site key key file.

2.1 Create a certificate folder

We create a certs folder in the root directory of the D disk to save the certificate file.
Create another certificate folder for the current domain name: site1
Then copy the obtained certificate file to the site1 file.

The details are as follows:

2.2 Modify the cpolar configuration file

Use vs code to open the cpolar configuration file

In the configuration file, find the WordPress tunnel. Under the tunnel, add two parameters, crt and key, as shown in the red box in the figure below.

Parameter Description:

crt: the full path of the site's certificate file
key: the full path of the site key file

Save and exit.

2.3 Restart the cpolar service

In the taskbar search, enter 服务, click to open

In 服务the list, find Cpolar Service, click the right mouse button, select 重新启动, restart service.

2.4 Check whether the background Wordpress tunnel is online and normal

cpolar background – status – online tunnel list

2.5 Open the site test with a browser

Open the browser and use the https protocol to access the site, in this example: https://dev.bestexpresser.com/

We see the small lock next to the address, which proves that the configuration is successful!

Summarize:

We have applied for an HTTP certificate for the domain name and configured it in cpolar to make our site more formal and our users more secure.
