Alpine Linux NGINX 1.15.3+

Note: The Nginx Module for Alpine Linux requires Nginx v1.15.3 or higher.

Add the Package Repositories

We’ll first add in the Signal Sciences apk repositories as this simplifies the installation process:

apk update && apk add wget
wget https://apk.signalsciences.net/sigsci_apk.pub ; mv sigsci_apk.pub /etc/apk/keys
echo https://apk.signalsciences.net/3.12/main | tee -a /etc/apk/repositories && apk update

sudo apk update && sudo apk add wget
sudo wget -q https://apk.signalsciences.net/sigsci_apk.pub ; sudo mv sigsci_apk.pub /etc/apk/keys
sudo echo https://apk.signalsciences.net/3.12/main | sudo tee -a /etc/apk/repositories && sudo apk update

apk update && apk add wget
wget https://apk.signalsciences.net/sigsci_apk.pub ; mv sigsci_apk.pub /etc/apk/keys
echo https://apk.signalsciences.net/3.11/main | tee -a /etc/apk/repositories && apk update

sudo apk update && sudo apk add wget
sudo wget -q https://apk.signalsciences.net/sigsci_apk.pub ; sudo mv sigsci_apk.pub /etc/apk/keys
sudo echo https://apk.signalsciences.net/3.11/main | sudo tee -a /etc/apk/repositories && sudo apk update

Optional: Verify Signing Key

Verify the downloaded key contains the proper key:

openssl rsa -pubin -in /etc/apk/keys/sigsci_apk.pub -text -noout

Expected modulus output:

Install the Module With apk

Install the module by running the following command, replacing “NN.NN” with your Nginx version number:

apk add nginx-module-sigsci-nxo-1.NN.NN

Update the Nginx Configuration

Edit your nginx.conf file located by default at /etc/nginx/nginx.conf. Add the following lines to the global section. For example after the pid /run/nginx.pid; line add:

load_module /etc/nginx/modules/ngx_http_sigsci_module.so;
load_module /etc/nginx/modules/ndk_http_module.so;

Restart the Nginx web service

Restart Nginx running on a VM and bare-metal:

sudo service nginx restart
sudo rc-service nginx restart
