第一行的ForeverJS bash脚本错误

Question

Im trying to get a foreverJS script to run a Node server on an EC2 instance. The script looks like:

#!/bin/bash
forever stopall
forever hakuna-matata store in appropriate logs start 'full/qualified path'

Even if I add an echo "getting here" statement as the first line I still get an error. I do not know bash scripting well, so it may be permissions, relative/absolute path, EC2/node, environment variable related, but I honestly do not know.

Stacktrace:

[ec2-user@12-34-56 folder]$ forever startup.sh
warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
/home/user/var/www/folder/startup.sh:2
echo "gh"
     ^^^^

I also tried via running the script via the forever service script with forever start startup.sh and get the same error. I've launched from the parent direct and with a (qualified) path.

Ask if you need additional environmental information...

Forever assumes SCRIPT is a JS file that can be executed with Node.js You're trying to run a bash script instead, so it errors out since echo "getting here" obviously isn't valid JS code.

To fix this, you need to use the -c command line option when running forever . From the docs :

-c  COMMAND      COMMAND to execute (defaults to node)

So in your case, you'd set -c to /bin/bash ; like this:

forever start [LOG OPTIONS] -c /bin/bash path/to/your-shell-script.sh
