Bitnami SSL install tool issue with Wordpress multisite

Question

Hi all, I am using the Bitnami wordpress multisite package on my new lightsail instance hoping to host multiple wordpress websites on one instance, I first set the primary domain for the multisite instance as `primarydomain.com` using: `sudo /opt/bitnami/configure_app_domain --domain primarydomain.com` (according to the doc this is a must), I then installed SSL for primarydomain.com using `sudo /opt/bitnami/bncert-tool`, everything worked fine so far since there is only 1 site at this time.

Then I created a 2nd site `secondarydomain1.com`, but after I install SSL for it using the same command `sudo /opt/bitnami/bncert-tool`, I found the primary domain of the multisite instance is automatically changed from `primarydomain.com` to `secondarydomain1.com` in `/opt/bitnami/apache/conf/httpd.conf` file:

removed:
`primarydomain.com`

inserted:
`secondarydomain1.com:80`

This caused both domain `primarydomain.com` and `secondarydomain1.com` not working properly.. Has anyone seen this issue before? or any idea what went wrong and how to fix it? Thank you!

bn-cert will foul up the server configuration so bad it will have to be restored -- it happened to me!  Make sure you have a good snapshot to go back to before running it.

The issue you're experiencing is related to how the Bitnami SSL installation tool interacts with WordPress Multisite configurations on Lightsail. When you use the `bncert-tool` to install SSL for additional domains in a WordPress Multisite setup, it can inadvertently modify the primary domain configuration.

To resolve this issue and properly manage SSL for multiple domains in your WordPress Multisite instance, you should follow these steps:

1. First, revert the changes made by the SSL tool by manually editing the `/opt/bitnami/apache/conf/httpd.conf` file to restore `primarydomain.com` as the primary domain.

2. Instead of using the `bncert-tool` for each additional domain, you should configure SSL for all your domains at once. Use the `bncert-tool` with multiple domain names separated by spaces:

```
sudo /opt/bitnami/bncert-tool --domains "primarydomain.com secondarydomain1.com"
```

This approach will configure SSL for all specified domains without altering the primary domain setting.

3. After configuring SSL, you may need to update your WordPress Multisite configuration to recognize the additional domains. This typically involves editing the WordPress configuration file and updating DNS records.

4. Remember to update your DNS records for each domain to point to your Lightsail instance's IP address.

5. If you add more domains in the future, you'll need to run the `bncert-tool` command again with all domains included.

By following these steps, you should be able to maintain the correct primary domain configuration while still securing all your WordPress Multisite domains with SSL certificates. If you continue to experience issues, you may need to consult Bitnami's documentation or reach out to AWS Lightsail support for further assistance.
