How to restart with Einhorn

[abramovic]

When using Einhorn I know we can specify a PID file to write to such as "einhorn -e einhorn.pid ./main" but whenever I kill that PID the entire process dies.

How do I get the PID of the worker and not the master so I can do "kill -USR2 PID"

[abramovic]

Never mind. Just realized I can just use pgrep -n process-name

To initiate a graceful restart using einhorn, you typically send HUP to the einhorn process itself—einhorn is responsible for sending its children USR2 as appropriate.
