* bin * code * error_docs * httpdocs * lib64 * logs * tmp * var * chat(my node.js folder)     * node_modules         * pm2         * sockjs     * server.js * dev * etc * lib * local * sbin * usr

i entered folder typing cd chat , installed pm2 npm install pm2.

after tried use pm2 server.js typing pm2 server.js server returns "pm2 command not found". can use node.js without problem pm2 not working.

install pm2 globally:

run root:

or if user sudo-er

sudo npm -g pm2

and go user (or stay in root if created root user) , run it:

pm2 start server.js
