haproxy-upstart-wrapper

-----------------------

A wrapper for haproxy that works with Upstart so that reload signals are processed properly.

Just in time for Debian to switch to systemd.

install

-------

```bash

$ npm install -g haproxy-upstart-wrapper

```

motivaion

---------

The init script that comes with the haproxy package in Debian/Ubuntu is not an

Upstart script. I have found the existing init script to be unreliable on 

reboots. In trying to convert the existing init script to an upstart job I

discovered the unique way that haproxy seamlessly reloads config files.

Upstart can only send a signal to a process to tell it to reload its config

files, while haproxy starts a whole new process after telling the currently

running process to stop listening on specified ports. As a result of this

incompatability, here is this wrapper script which starts haproxy, listens

for the reload signal and then executes the process restarting procedure.

usage

-----

Install the upstart job with:

```bash

$ haproxy-upstart-wrapper --install

```

Uninstall the upstart job with:

```bash

$ haproxy-upstart-wrapper --uninstall

```

Then you can use the normal upstart commands to manage haproxy:

```bash

$ service haproxy start

$ service haproxy reload

$ service haproxy stop

```
