LaunchD Plist not working

问题

EDIT: It appears as if I am getting an error in the console com.apple.launchd: (com.xxxx.adbind[57]) Exited with code: 1

What does that even mean?

Also; if I load the launchd plist file logged in by using the launchctl command it works fine!

I'm driving myself crazy trying to figure out why my launchd is not working. I'm using this in Mountain Lion 10.8.2 When I manually start it using launchctl it says it's loaded, but the script is not running. The script when ran manually works fine as well. Perhaps it just needs a better set of eye's to look at what I'm doing.

First, I'll explain what it is I'm trying to accomplish. I'm having about 400 computers imaged off site. I need these computers bound to AD, which can't be done out of our network. I figured by having a launchd script run at startup to call a script, then have the script check to see if it's in the network before it runs I can have these computers bound at first startup in our network before an AD user logs in.

Here's my launchd, I'm putting it in /Library/launchDaemons

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.xxxx.adbind</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/adbind.bash</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>WorkingDirectory</key>
    <string>/usr/local/bin</string>
</dict>
</plist>

I've tried using this with and without a WorkingDirectory key.

Here's my script, I'm putting my script in /usr/local/bin

#!/bin/bash

## Remove the script and launchd job. Be sure to delete the script.
launchctl unload -w /Library/LaunchDaemons/com.xxxx.adbind.plist

exit 1
fi

Thanks for any help!

回答1:

Exit code 1 means the script exited with an error condition. If it exited with a 0 it would mean there were no errors.

Well, I finally worked through my problem and have found a solution! I'm going to post the answer here in order to hopefully help someone else someday! It seems as if the launchd file wasn't running long enough to run my entire script. So I added the KeepAlive key to the plist. It looks like this now.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.xxxx.adbind</string>
    <key>KeepAlive</key>
    <dict>
        <key>SuccessfulExit</key>
        <false/>
    </dict>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/adbind.bash</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

I also had troubles with permissions and found that the "bin" folder I created and placed the script into wasn't owned by root. So I ran chown and chmod on my files and folders. Like this.

sudo chown root:wheel bin
sudo chown root:wheel adbind.bash
sudo chmod 755 adbind.bash
sudo chown root:wheel com.xxxx.adbind.plist
sudo chmod 755 com.xxxx.adbind.plist
