PM2 command not found

Question

I installed node.js and npm to my centOS 7 server. But i have problems with pm2. Actually real problem is i don\'t have experiences in linux and i don\'t know how to change

Answer 1

PM2 the process manager for Node.js applications. PM2 basically manages applications (run them in the background as a service). So this is how we install PM2 globally with sudo permissions account

sudo npm install -g pm2

The -g option tells npm to install the module globally, so that it's available system-wide. Once this is installed, check the installed path as:

whereis pm2
pm2: /opt/node/bin/pm2 /opt/node/lib/node_modules/pm2/bin/pm2

Now, we need to add this path in startup bash script. Add add the following line anywhere in ~/.bashrc file.

export PATH=$PATH:/opt/node/lib/node_modules/pm2/bin

Now re-login or source the bash script as follows(so that bash script runs and path is set)

 source ~/.bashrc

and now it should run. check the status of pm2

pm2 status
