问题
Built a new Windows Server 2016 to act as a target for jenkins orchestrated builds. We are not supposed to use oracle java anymore, so I got coretta openJDK. OpenJDK does not support javaws any more. The executable does not ship with it. I have seen some scripted workarounds, but they do not work and are poorly written to boot.
What are we supposed to use to launch slave agents on Windows machines?
回答1:
There are several ways to implement this but since this is a windows server you can follow steps on https://github.com/kohsuke/winsw/blob/master/doc/installation.md#winsw-installation-guide to install jenkins slave as service without javaws.
回答2:
I believe @Mike was referring to: Install Slave as a Windows service (cmd version), which does not need JNLP/javaws.
OR, under Jenkins 2 (we are using 2.121.1 plus WMI Windows Agents (aka windows-slaves:1.4), there is now an option to "Let Jenkins control this Windows slave as a Windows service", essentially in the same fashion as a Linux node.
You must have an Admin account (and password). We had to follow the guidance to edit registry when "Windows agents fail to start via DCOM" (Guidance is for Server 2012) to remotely manage the service. So far, seems to be working OK, YMMV. So far, seems to be working OK, no "subtle probelms"; YMMV.
For entries:
- HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID{72C24DD5-D70A-438B-8A42-98424B88AFB8}
- HKEY_CLASSES_ROOT\CLSID{76A64158-CB41-11D1-8B02-00600806D9B6}
(There are several matches for the keys; just change the two locations indicated)
- Launch 'regedit' (as Administrator)
- Find (Ctrl+F) the following registry key: "{72C24DD5-D70A-438B-8A42-98424B88AFB8}" in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\
- Right click and select 'Permissions'
- Change owner to administrators group (Advanced...).
- Change permissions for administrators group. Grant Full Control.
- Change owner back to TrustedInstaller (user is "NT Service\TrustedInstaller" on local machine)
- Repeat the steps 1-6 for HKEY_CLASSES_ROOT\CLSID{76A64158-CB41-11D1-8B02-00600806D9B6}
- Restart Remote Registry Service (Administrative Tools / Services)
