A custom init.d start-up script for HAProxy: start, stop, restart, reload, checkconfig
时间:2014-12-14 22:01 来源:linux.it.net.cn 作者:IT
I created the following init.d script for HAProxy, which will allow you to add it to the automatic start-up, and perform a start, stop, restart, reload and checkconfig on it.
The reload option was created based on the excellent post titled “HAProxy: Reloading Your Config With Minimal Service Impact“, by Michael Goffin.
Here’s how to add it in your auto start-up, once the file is in the /etc/init.d directory.
$ chkconfig --add haproxy
$ chkconfig haproxy on
And here’s the init.d script itself. You might have to change the paths to the binary and config file, depending on your set-up. If the layout gets funky, download the file directly: haproxy.init.

Or you can download it from this site.
$ wget http://mattiasgeniar.be/downloads/haproxy/haproxy.init -O /etc/init.d/haproxy
And modify it as you see fit.
