使用pdsh远程运行node.js pm2

Question

I have 4 servers running node.js with the help of pm2 (pm2 start app.js). I would like to restart pm2 on all 4 servers from another server using pdsh however when I run:

pdsh -a "/root/.nvm/v0.10.30/bin/pm2 restart 0"

it returns:

/root/.nvm/v0.10.30/bin/pm2: line 4: exec: : not found

I have also done similar to bellow:

pdsh -a "sh /etc/profile && sh ~/.bash_profile && /root/.nvm/v0.10.30/bin/pm2 restart 0"

and same error occurs.

Thanks

Answer 1

Try to run pm2 directly from the node path. It appears that pdsh can't load nvm

If you've installed it from nvm it should be something like that:

~/.nvm/v0.10.30/bin/node

Pm2 on the other hand should be in the node_modules directory:

~/.nvm/v0.10.30/lib/node_modules/pm2/bin/pm2

So if we combine all this it becomes:

/root/.nvm/v0.10.30/bin/node /root/.nvm/v0.10.30/lib/node_modules/pm2/bin/pm2 restart 0
