SOLVED Jail - Problem with startup scripting

[TiagoShadow]

Hi Everyone,

I've recently installed TrueNAS on my server, it was previously a Windows machine for general Game Servers and NodeJs Web App, but I wanted to have a personal cloud service so I decided to try this, so I'm recently new to TrueNas and unexperienced when it comes to Linux.

I was able to configure and set up Nextcloud with localstorage and a mountpoint to a windows shared dataset, so I could access my cloud folders from the network, there was a lot of documentation and videos explaining.
But when it comes to NodeJS there is no almost nothing online, I've created a default jail, and installed node and npm packages to it. I wanted to run nodejs server from a folder inside nextcloud, I was able to do achieve, the only setback was since the I've these folders also shared with windows network, I cannot install node modules in those folders, only globally
So all I had to do to start Node was to 'envset' the path to Nodejs global modules, and then I could run my nodejs app with no problems in shell, but if I close the window my server closes and when I open the shell again the 'envset' I've created is gone. I've looked and the solution for this was to create a rc script

I've created the following script and saved it on '/ect/rc.d' folder, but it does not work. When I restart the jail nothing happens...

Try this as /usr/local/etc/rc.d/node:

Code:

#!/bin/sh
#
# PROVIDE: node
# KEYWORD: shutdown
#
# Add the following to /etc/rc.conf[.local] to enable this service
#
# node_enable="YES"
#

. /etc/rc.subr

: ${node_enable="NO"}

name=node
rcvar="node_enable"

start_cmd="node_start"
stop_cmd="/usr/bin/true"

node_start()
{
        if ! checkyesno node_enable ; then
                return 0
        fi

        export NODE_PATH="/usr/local/lib/node_modules:/usr/local/bin/node:/media/Vision/visionOS/app.js"
}


load_rc_config ${name}
run_rc_command "$1"

Also remember to chmod +x /usr/local/etc/rc.d/node and sysrc node_enable="YES".

        fi

        export NODE_PATH="/usr/local/lib/node_modules:/usr/local/bin/node:/media/Vision/visionOS/app.js"
}


load_rc_config ${name}
run_rc_command "$1"

Also remember to chmod +x /usr/local/etc/rc.d/node and sysrc node_enable="YES".

It did not work, 'syrc' and 'export' commands do not exist, never the less I've tried it, didn't work, changed from export to setenv, did not work, tried in the both '/etc/rc.d' and '/usr/local/etc/rc.d' which the latter did not exit in my system so I've created the folder, didn't work

Did you do this on the host or inside the plugin?

 

[TiagoShadow]

I'm not sure if its diferent or not, again, new to this, but I don't have a plugin for this, only a jail
I did it inside the jail, that's where I've node installed and have it working when I open shell and execute node, the if I close the jail shell it shuts down the node js server

OK, then you don't need a start script. You'll need to modify the NodeJS launcher script to include export NODE_PATH="/usr/local/lib/node_modules:/usr/local/bin/node:/media/Vision/visionOS/app.js".

The script to launch NodeJS is the one that I posted here originally

this was suppose to run when the jail started, and first line is to set the environment path 'NODE_PATH' to 'user/local/lib/node_modules' and the next line is to run node.js '/usr/local/bin/not /media/Vision/visionOS/app.js' starts the node server.
This is basically what I do when I open the jail shell to start the server, but it closes if I close the jail shell window, I needed this to run on start of the jail, even if the shell was not opened.

I'm sorry if I did not explain it well on the first post

Hi,

Just wanted to share that I was able to fix the issue, in a desperate developer move I looked into other codes in the folder /rc.d and saw what they had, so I experimented with adding and removing stuff until it worked.

The result:
#!/bin/sh # # PROVIDE: node # KEYWORD: shutdown # REQUIRE: DAEMON # # Add the following to /ect/rc.conf[.local] to enable this service # # node_enable="YES" . /etc/rc.subr name="node" desc="NodeJS Server" rcvar="node_enable" start_cmd="node_start" stop_cmd=":" node_start() { export NODE_PATH="/usr/local/lib/node_modules:/usr/local/bin/node:/media/Vision/visionOS/app.js" exec /usr/local/bin/node /media/Vision/visionOS/app.js } load_rc_config ${name} run_rc_command "$1"
I'm not sure if it is the line Require that makes the script run a bit later in the lifecycle of the jail fixed it, or the removal of ': ${node_enable="NO"}' makes the diference

Glad you figured it out yourself.
