Configure NGINX Web Server Configure Apache Web Server

Step 3: Configure the Web Server

Update your web server software's configuration to use the HTTPS certificate and corresponding fake PEM private key that you created in the previous step. Remember to backup your existing certificates and keys before you start. This will finish setting up your Linux web server software for SSL/TLS offload with AWS CloudHSM.

Complete the steps from one of the following sections.

Topics

Configure NGINX Web Server
Configure Apache Web Server

Configure NGINX Web Server

Use this section to configure NGINX on supported platforms.

To update the web server configuration for NGINX

Connect to your client instance.
Run the following command to create the required directories for the web server certificate and the fake PEM private key.
```
sudo mkdir -p /etc/pki/nginx/private
```
Run the following command to copy your web server certificate to the required location. Replace <web_server.crt> with the name of your web server certificate.
```
sudo cp <web_server.crt> /etc/pki/nginx/server.crt
```
Run the following command to copy your fake PEM private key to the required location. Replace <web_server_fake_PEM.key> with the name of the file that contains your fake PEM private key.
```
sudo cp <web_server_fake_PEM.key> /etc/pki/nginx/private/server.key
```
Run the following command to change the file ownership so that the user named nginx can read them.
```
sudo chown nginx /etc/pki/nginx/server.crt /etc/pki/nginx/private/server.key
```
Run the following command to back up the /etc/nginx/nginx.conf file.
```
sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.backup
```

Use a text editor to edit the /etc/nginx/nginx.conf file. At the top of the file, add the following lines:

Amazon Linux


ssl_engine cloudhsm;
env n3fips_password;

Then uncomment the TLS section of the file so that it looks like the following:
