haproxyctl's Introduction

HAProxyCTL

This is a simple wrapper to make life with HAProxy a little more convenient.

Acts as an init script for start, stop, reload, restart, etc
Leverages 'socket' to enable and disable servers on the fly
Formats server weight and backends in a readable way
Provides Nagios and Cloudkick health checks
chkconfig/service-able for Redhat folk

Here is a presentation about it. Hit space to advance slides.

Installation

On most UNIX, assuming HAProxy is in the $PATH:

git clone [email protected]:flores/haproxyctl.git
ln -s haproxyctl/haproxyctl /etc/init.d/haproxyctl

For chkconfig/RedHat/Centos, add:

chkconfig --add haproxyctl

Or if have RubyGems, just gem install it!

gem install haproxyctl

Or if you are on Debian, just install haproxy with apt-get!

apt-get install haproxyctl

There is also an HAProxy source installation script. This installs not only the steps above but also HAProxy itself.

Options

# ./haproxyctl help
usage: ./haproxyctl 
  where argument can be:
    start: start haproxy unless it is already running
    stop: stop an existing haproxy
    restart: immediately shutdown and restart
    reload: gracefully terminate existing connections, reload /etc/haproxy/haproxy.cfg
    status: is haproxy running?  on what ports per lsof?
    configcheck: check /etc/haproxy/haproxy.cfg
    nagios: nagios-friendly status for running process and listener
    cloudkick: cloudkick.com-friendly status and metric for connected users
    show health: show status of all frontends and backend servers
    show backends: show status of backend pools of servers
    enable all : re-enable a server previously in maint mode on multiple backends
    disable all : disable a server from every backend it exists
    enable all EXCEPT : like 'enable all', but re-enables every backend except for 
    disable all EXCEPT : like 'disable all', but disables every backend except for 
    clear counters: clear max statistics counters (add 'all' for all counters)
    help: this message
    prompt: toggle interactive mode with prompt
    quit: disconnect
    show info: report information about the running process
    show stat [counter...]: report counters for each proxy and server
    show errors: report last request and response errors for each proxy
    show sess [id]: report the list of current sessions or dump this session
    get weight: report a server's current weight
    set weight: change a server's weight
    set timeout: change a timeout setting
    disable server: set a server in maintenance mode
    enable server: re-enable a server that was previously in maintenance mode

Examples

Status check

  ./haproxyctl status
  haproxy is running on pid 23162.
  these ports are used and guys are connected:

  173.255.194.115:www->83.39.69.106:19338 (ESTABLISHED)

Errors to the backend servers

  ./haproxyctl "show errors"

Disable servers on the fly

  ./haproxyctl "show health" |grep nginx_belem
  static      nginx_belem               MAINT   1

Graceful reloads

  ./haproxyctl reload
  gracefully stopping connections on pid 23162...
  checking if connections still alive on 23162...
  reloaded haproxy on pid 1119

does normal things like checks if a process is running before starting it...

  ./haproxyctl start    
  ./haproxyctl:35: haproxy is already running on pid 20317! (RuntimeError)
  
  ./haproxyctl restart
  stopping existing haproxy on pid 20317...
  waiting a ms...
  checking if haproxy is still running...
  starting haproxy...
  done.  running on pid 20348

keeps all the regular UNIX socket stuff

haproxyctl's Issues

Hi,
thanks for this great haproxyctl tool. In my use case, I have multiple haproxy instances on the same loadbalancer. The config files are split into generic parts end specific parts per instance. This modular approach is more scaleable and we can edit only 1 generic configpart which is used on all instances in just one file. As far as I can see, it is not possible to point haproxyctl to for example N configfiles of haproxy instance X without changing the ruby code. Do you have plans to support multiple haproxy instances and multiple configfiles in the future?

Kind regards,

Move this to an Org?

I'm thinking of moving this to an org and hoping some trustworthy folks are up for commit access. Thoughts, objections, volunteers?

debian jessie dependencies

I'm not clear on who maintains the debian package, so this may not be the correct place to report this.

I've installed haproxyctl from a debian jessie install.

I get the following error.

haproxyctl status

haproxy is running on pid 10019.
these ports are used and guys are connected:
sh: 1: lsof: not found

lsof needs to be added as a dependency, so it is installed along with the package.

Unable to down server ( permission denied )

Hello, I can seem to down servers, not sure why I am getting permission denied:

➜  bin git:(master) ✗ /etc/init.d/haproxyctl "disable server api_tropo/jboss2"
Permission denied

I am running this as root, so I should have full access tot he socket file. Other "read only" type commands work fine, its write actions that seem to be giving me issues... Any ideas?

haproxyctl fails if PID file doesn't exist

"haproxyctl start" fails if no pid file exists, which is a bit of a Catch 22 since haproxy creates the file when it has started.

disable server doesn't work

This example:

./haproxyctl "disable server static/nginx_belem"

Doesn't work and just returns:

show info : report information about the running process
show stat : report counters for each proxy and server
show errors : report last request and response errors for each proxy
show sess : report the list of current sessions

Without doing anything. I've tried every variation of quotes, etc...

I looked at the actual script: https://github.com/flores/haproxyctl/blob/master/bin/haproxyctl

I don't see any cases for handling "disable server"

There only appears to be support for "disable all EXECPT X" and "disable all".

So either the documentation is wrong and discussing features that don't exist, or I'm doing something wrong...

LoadError

Hi, I tried to install your script. I did what instruction say but I got that error when try to run it.

-# service haproxyctl "show health"
/etc/init.d/haproxyctl:17:in `require': no such file to load -- haproxyctl (LoadError)
from /etc/init.d/haproxyctl:17

How can I solve it? Thank you...

`nbproc': undefined method `[]' for nil:NilClass (NoMethodError)

Hi, with the latest release I get this error when running sudo service haproxyctl show health:

Not really sure how to troubleshoot this, but more than willing to provide any further information

sudo haproxyctl reload
# gracefully stopping connections on pid 4557...
# ....
# CTRL+C
#  reloaded haproxy on pid

But it never goes beyond first line message. Is this a known issue?
I pulled from SID / did not make from source.
