INSTALLATION PROCEDURE & PLATFORM INFORMATION
Siege was originally built and tested on GNU/Linux. It has been ported
to other platforms. See the MACHINES document for more details.
This program was built using the GNU autoconf mechanism. If you are
familiar with GNU applications, then siege should present few problems
especially on the above mentioned platforms. For best results, use gcc.
IMPORTANT: If you are upgrading from an earlier version, you MUST delete
the older version before installing this one. The simplest way to remove
the older version to run "make uninstall" in the old source directory.
If you no longer have the old source, you can configure the new version
to be installed in the same place as the old version. Then BEFORE you
run "make install", run "make uninstall" first.
"Hey! I'm impatient, I only read these things when things go wrong!"
If that is the case, then follow the steps in item #1 below...
XXX: If you pulled this code from github.com then you won't have a
configure script. You'll need to build one. How do you do that? In
the top level source directory run this:
NOTE: the bootstrap requires GNU autotools in order to run. You'll
need autoconf, automake and libtool installed on your computer
1. In a nutshell, to install the application in the default directory,
( /usr/local ), run the following commands:
$ ./configure (IMPORTANT: see step 2 for enabling https support)
$ make uninstall (if you have an older version installed in PREFIX)
$ make install
This will install the application ( siege ) in the default directory
/usr/local/bin. If that directory is in your PATH, then to run siege
and view the online help type:
$ siege --help
To learn more about siege, make sure /usr/local/man is in your
MANPATH and type:
$ man siege
For more detailed information about running siege and stress testing
HTTP servers, type:
$ man layingsiege
For more details, read on. Especially if you want to install siege
in a directory other that /usr/local/bin
The configure script attempts to guess the values which are set
on your platform. If all goes well, you should only have to run it
with some preferred arguments. The more notable ones are listed
--help prints the configure script's help section
--prefix=/some/dir installs the files in /some/dir
--bindir=/some/bin installs the executable in /some/bin
--mandir=/some/man installs the man page in /some/man
--with-ssl=/some/dir where dir is where you installed ssl, this
flag is used to enable https protocol.
Since siege is a pretty esoteric program, I prefer to install it in
my home directory. For this reason, I run configure with my home
directory as the prefix.
$ ./configure --prefix=/export/home/jdfulmer
If you don't already, make sure $HOME/bin and $HOME/man are set
appropriately in your .profile. In my case, I set them like this:
# jdfulmer's profile
export PATH MANPATH
To reload your profile without logging out, do this:
$ . .profile
If it runs successfully, the configure script creates the Makefiles
which lets you build the program. After you configure your
environment, the next step is to build siege. If that step fails, you
may have to return to this step. Reasons for reconfiguring are
mentioned below. If configure failed to create Makefiles, then you
have problems which may be beyond the scope of this document, such as
no compiler ( you'll have to get one ), no libraries (again, an
acquisition on your part).
To enable https, you must have ssl installed on your system. Get the
latest version from http://www.openssl.org. AFTER ssl is installed,
then you have to configure siege to use it:
$ ./configure --prefix=/some/dir --with-ssl=/ssl/install/dir
The openssl default installation is /usr/local/ssl. If you installed
openssl in that directory, then you would configure siege like this:
$ ./configure --prefix=/some/dir --with-ssl=/usr/local/ssl
$ make uninstall (if you have a previous version already installed)
$ make install
To compile the program, execute the second step of the nutshell
version mentioned in item #1: type "make" and hope for the best.
If your environment was configured without errors, then configure
should have generated the Makefiles that will enable this step to
The make command will invoke your compiler and build siege. If you
are using gcc on any of the platforms mentioned above, then you
should not have problems. In general, any ANSI C compiler should
Some systems may require options that were not set by the configure
script. You can set them using the configure step mentioned above:
$ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
You can also set them by editing the Makefiles that were created as
a result of running configure, but this is not preferred.
If the program compiled successfully, follow the third nutshell step
and type "make install" This will install the package in the
directories that you've selected in the configuration step. If they
are not already, make sure PREFIX/bin and PREFIX/man are in your PATH
and MANPATH respectively. This process is described in detail above.
siege --> SIEGE_HOME/bin/siege
bombardment --> SIEGE_HOME/bin/bombardment
siege2csv --> SIEGE_HOME/bin/siege2csv
siege.config --> $HOME/.siege/siege.config
cookies.txt --> $HOME/.siege/cookies.txt
siege.1 --> SIEGE_HOME/man/man1/siege.1
bombardment.1 --> SIEGE_HOME/man/man1/bombardment.1
siege2csv.1 --> SIEGE_HOME/man/man1/siege2csv.1
To remove the package, type "make uninstall" To make the source
directory completely clean, type "make distclean". There are
differences of opinion regarding this option. Some people claim that
it should not be available as it depends the original Makefiles from
the source directory. Since I tend to hoard all source code, I like
The point is, if you've installed one version of siege in /usr/local
and another version in $HOME, then make uninstall is obviously not
going to work in both locations. The safest thing to do is manually
remove the files which were installed by make install. The files and
their locations are described in item #4.
6. Read the documentation
The online help is pretty straight forward ( siege --help ):
Usage: siege [options]
-V, --version VERSION, prints the version number.
-h, --help HELP, prints this section.
-C, --config CONFIGURATION, show the current config.
-v, --verbose VERBOSE, prints notification to screen.
-q, --quiet QUIET turns verbose off and suppresses output.
-g, --get GET, pull down HTTP headers and display the
transaction. Great for application debugging.
-c, --concurrent=NUM CONCURRENT users, default is 10
-r, --reps=NUM REPS, number of times to run the test.

-f, --file=FILE FILE, select a specific URLS FILE.
-R, --rc=FILE RC, specify an siegerc file
-l, --log[=FILE] LOG to FILE. If FILE is not specified, the
default is used: PREFIX/var/siege.log
-m, --mark="text" MARK, mark the log file with a string.
between .001 and NUM. (NOT COUNTED IN STATS)
-H, --header="text" Add a header to request (can be many)
-A, --user-agent="text" Sets User-Agent in request
-T, --content-type="text" Sets Content-Type in request
For more detailed information, consult the man pages:
$ man siege
$ man siege.config

7. Edit the .siege/siege.config file in your home directory. This file
contains runtime directives for siege. Each directive is well
documented with comments. Some directives exist ONLY in this file;
they don't have a command line option. If you are upgrading from an
earlier version, your original version is kept and a new resource
file is installed as .siegerc.new. In order to take advantage of any
new directives, you might want to use this new file instead.
