Activating FastAGI

With very busy servers, it can help to offload the AGI scripts to another server or process. The load is reduced because there is no need to spawn a process every time a new AGI script is run.

install node

curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
sudo yum install -y nodejs
npm install -g npm

install pm2

sudo npm i -g pm2
copy fastagi node script to /var/lib/asterisk/agi-bin directory

Copy the whole node folder https://git.freepbx.org/projects/FREEPBX/repos/core/browse/node

run pm2 at start up

pm2 startup
pm2 install pm2-logrotate
start fast agi script with pm2
pm2 start /var/lib/asterisk/agi-bin/node/fastagi-server.js (--watch) dont use watch it reloads for all files in the path
pm2 save
pm2 list
pm2 update

centos 6

cd ~
wget http://nodejs.org/dist/v10.15.1/node-v10.15.1-linux-x64.tar.gz # (Must check the latest version change the version name accordingly)
sudo tar --strip-components 1 -xzvf node-v10.15.1-linux-x64.tar.gz -C /usr/local # (Must check the latest version change the version name accordingly)

Verify by using: node --version

npm i -g pm2

On the MiRTA PBX side, you can edit the extensions.ael and uncomment the row at top, in globals section (but this change will be overwritten at every upgrade) or add a file in /etc/asterisk/extensions.d named for example fastagi.ael and containing:

 globals {
     FASTAGI=agi://127.0.0.1/;
 };

You need to reload AEL only the first time
