Daemonizing Jetty?

[David Langenberg]

If you're on a SystemD-based distro, here's some instructions that work on
CentOS 7.  YMMV on other systems:

Courtesy of the InCommon Shib Training Team:


1) Create the file /etc/systemd/system/shibboleth.service using your
favorite editor and save the following there (Note, what follows is
case-sensitive:

[Unit]
Description=Shibboleth Identity Provider

[Service]
WorkingDirectory=/opt/shibboleth-idp/jetty-base
ExecStart=/usr/bin/java -jar <path-to-jetty>/start.jar
jetty.home=<your-jetty-home> jetty.base=<your-custom-jetty-base>

[Install]
WantedBy=multi-user.target

2) Reload systemd: systemctl daemon-reload shibboleth

3) Start Shib: systemctl enable shibboleth && systemctl start shibboleth
