1. Supported Architectures and Requirements
-------------------------------------------

Supported architectures: Linux/i386, Linux/armv4l, FreeBSD/i386, OpenBSD/i386 Solaris/sparc64, NetBSD/sparc64
(for other architectures the Makefiles might need to be edited)

There are various configuration options defined in the Makefile.

Requirements:


- gcc / suncc / icc : gcc >= 2.9x; 4.[012] recommended (it will work with older version but it might require some options tweaking for best
performance)

- bison or yacc (Berkley yacc)

- flex

- GNU make (on Linux this is the standard "make", on FreeBSD and Solaris is called "gmake") version >= 3.79.

- sed and tr (used in the makefiles)

- GNU tar ("gtar" on Solaris) and gzip if you want "make tar" to work

- GNU install or BSD install (on Solaris "ginstall") if you want "make install", "make bin", "make sunpkg" to work

- openssl if you want to compile the TLS support

- libsctp if you want to compile the SCTP support

- libmysqlclient & libz (zlib) -libs and devel headers- if you want mysql DB support (the db_mysql module)

- libpq / postgresql -libs and devel headers- if you want postgres DB support (the db_postgres module)

- unixodbc -libs and devel headers- if you want unixodbc DB support (the db_unixodbc module)

- libexpat if you want the jabber gateway support (the jabber module) or the XMPP gateway support

- libxml2 if you want to use the cpl-c (Call Processing Language) or the presence modules (presence and pua*)

- libradius-ng -libs and devel headers- if you want to use functionalities with radius support - authentication, accounting, group support, etc

- unixodbc - libs and devel headers - if you want UNIXODBC support as DB underlayer

- libxmlrpc-c3 - libs and devel headers - if you want to have XML-RPC support for the Management interface (MI)

- libperl - libs and devel headers - if you want PERL connector to support perl scripting from you config file (perl module)

- libsnmp9 - libs and devel headers - if you want SNMP client functionality (SNMP AgentX subagent) for opensips

- libldap libs and devel headers v2.1 or greater - if you want LDAP support

- libconfuse and devel headers - if you want to compile the carrierroute module

OS Notes:

- FreeBSD/OpenBSD/NetBSD: make sure gmake, bison or yacc & flex are installed
- Solaris: as above; you can use Solaris's yacc instead of bison. You might need also gtar and ginstall.


2. Howto Build opensips From Source Distribution
-------------------------------------------

(NOTE: if make doesn't work try gmake instead)

- compile with default options (TLS support is enabled by "TLS=1"; SCTP support is enabled by "SCTP=1"):

make #builds only opensips core, equivalent to make opensips
make modules

or make all #builds everything

-compile debug mode version

make mode=debug all

-compile only the textops module

make modules=modules/textops modules

-compile all the "default" modules except textops and db_mysql

make skip_modules="textops db_mysql" modules

-compile all default modules and include uri_radius (not compiled by default):

make include_modules="uri_radius" modules

-compile all the modules from the modules subdirectory (even the one excluded by default):

make exclude_modules="" modules

-compile all the modules from the modules subdirectory excluding exec:

make exclude_modules=exec modules
or
make exclude_modules="" skip_modules=exec modules

-generate README file for textops module

make modules=modules/textops modules-readme

-compile with gcc-3.2 instead of gcc

make CC=gcc-3.2 all

or

CC=gcc-3.2 make all



Make targets:

Clean:

make clean (clean the modules too)
make proper (clean also the dependencies)
make distclean (the same as proper)
make mantainer-clean (clean everything, including auto generated files,tags, *.dbg a.s.o)

Compile:

make proper
make
(or gmake on non-Linux systems)
make modules
or make modules exclude_modules="exec" etc.

Make tags:

make TAGS

Create a tar.gz with the sources (in ../):

make tar

Create a tar.gz with the binary distribution (in ../):

make bin

Create a gzipped solaris package (in ../):

make sunpkg

Create debian packages (in ../):

make deb

or

dpkg-buildpackage

Install:

make prefix=/usr/local install

Note: If you use prefix parameter in make install then you also need to use this parameter in previous make commands, i.e. make, make modules,
or make all. If you fail to do this then OpenSIPS will look for the default configuration file in a wrong directory, because the directory of the
default configuration file is hard coded into opensips during compile time. When you use a different prefix parameter when installing then the
directory hard coded in opensips and the directory in which the file will be installed by make install will not match. (You can specify exact location
of the configuration file using -f parameter of opensips).

For example, if you do the following:
make all
make prefix=/ install

Then the installation will put the default configuration file into /etc/opensips/opensips.cfg (because prefix is /), but opensips will look for the
file in /usr/local/etc/opensips/opensips.cfg (because there was no prefix parameter in make all and /usr/local is the default value of prefix).

Workaround is trivial, use the same parameters in all make commands:
make prefix=/ all
make prefix=/ install

That applies to other make parameters as well (for example parameters
"modules" or "excluded_modules").


3. Quick-Start Installation Guide
----------------------------------------------

A) Getting Help

This guide gives you instructions on how to quickly set up OpenSIPS on your box. In case the default configuration does not fly, check
documentation at opensips site http://www.opensips.org/ to learn how to configure OpenSIPS for your site.

If the documentation does not resolve your problem you may try contacting our user forum by E-mail at users@opensips.org -- that is the mailing list
of opensips community. To participate in the mailing list, subscribe at the following web address:
http://www.opensips.org/cgi-bin/mailman/listinfo/users


B) Disclaimers

Note well the default "quick-start" configuration is very simple in order to be easily installable. It provides minimum features. Particularly,
authentication is by default disabled, which means anyone can register using any name with the server. (This is on purpose to avoid installation
dependencies on MySQL which is needed for storing user credentials.)


C) Quick Start

The following step-by step guide gives you instructions how to install the sql-free distribution of opensips. If you need persistence and authentication,
then you have to install additional MySql support -- proceed to section D) after you are finished with C).

1) Download an RPM or debian package from our site http://opensips.org/pub/opensips/latest/packages/
If you don't use an rpm or debian based distribution, see if corresponding packages are available or try our tar.gz'ed binaries.
If you use Gentoo Linux you do not have to download a package.For debian, packages are available via the Debian official repositories for
testing and unstable. For stable, use the project's repository at:
deb http://www.opensips.org/debian stable main

2) install the package
RPM:
rpm -i <package_name>
debian:
dpkg -i <package_name>
or if APT repository is used:
apt-get install <package_name>
gentoo:
emerge opensips
(or if use only stable packets: ACCEPT_KEYWORDS="~x86" emerge opensips)
tar.gz:
cd /; tar zxvf <package_name>_os_arch.tar.gz
(it will install in /usr/local/, and the configuration file in /usr/local/etc/opensips/opensips.cfg)
Solaris:
gunzip <package_name>.gz ; pkgadd -d <package_name>
*BSD:
pkg_add package_name
Note that the OpenSIPS package is in the FreeBSD package tree included, but is not present in the OpenBSD and NetBSD repository. You'll probably
have more luck trying to build directly from the source with the tar.gz,as the package files for this systems are somewhat out of date at the moment.

3) start the server
RPM + gentoo:

/etc/init.d/opensips start

debian:
opensips is started automatically after the install

(in case something fails you can start it with /etc/init.d/opensips start)

tar.gz:
the tar.gz does not include an init.d script, you'll have to create one of your own or adapt one from the source distribution (debian/init.d,

rpm/opensips.init.*, gentoo/opensips.init) You can start opensips directly with /usr/local/sbin/opensips.

Solaris:
see tar.gz.

4) optionally, watch server's health using the opensipsctl utility
- to do so, first set the environment variable SIP_DOMAIN to your domain name, e.g., in Bourne shell, call export SIP_DOMAIN="myserver.foobar.com"
- if you are using other than 'localhost' mysql server for maintaining subscriber database, change the variable 'SQL_HOST' to the proper
host name in the opensipsctl script
- run the opensipsctl utility
/usr/sbin/opensipsctl moni
or
/usr/local/sbin/opensipsserctl moni (if you installed from a tar.gz or solaris package)
- you can create a resource file for opensipsctl, name it .opensipsctlrc and place it in your home directory. You can set there the values for
opensipsctl variables (e.g., SIP_DOMAIN, SQL_HOST, SQL_USER, SQL_DB ...)

5) Register with the server using your favourite SIP User Agent.
For example, users of Windows Messenger need to set in Tools->Options->Accounts the following values:
Sign-in Name: <username>@<your_server_address>
Advanced->Configure Settings (on)
Advanced->Server: <your_server_address>
Connect Using: UDP


D) opensips with Persistent Data Storage

The default configuration is very simple and features many simplifications. In particular, it does not authenticate users and loses User Location database
on reboot. To provide persistence, keep user credentials and remember users'locations across reboots, opensips can be configured to use MySQL. Before you
proceed, you need to make sure MySQL is installed on your box.

1) Download the package containing mysql support for opensips from:
http://www.opensips.org/pub/opensips/
(rpm and deb provided, most of the binary tar.gz distributions and the solaris package include it; if it is not present you'll have to rebuild
from the source).
For gentoo please include 'mysql' to your USE variable in /etc/make.conf or give it as variable to the emerge command.

2) install the package
RPM based:

rpm -i <package_name>

DEB based:
dpkg -i <package_name>
or if APT repository is used

apt-get install <package_name>

Gentoo Linux:
emerge opensips
(if do not want to put 'mysql' into your USE variable you can type:

USE="mysql" emerge opensips)

3) create SQL tables
You must specify your database type in the /etc/opensipsctlrc file, e.g.MySQL. See section 7 for an explanation of further possible parameters.
- if you have a previously installed OpenSIPS on your system, use
/usr/sbin/opensipsdbctl migrate to convert your OpenSIPS database into new structures
NOTE: "migrate" is available only for mysql DBs - otherwise, if this is your very first installation, use
/usr/sbin/opensipsdbctl create to create OpenSIPS database structures (you will be prompted for password of MySQL "root" user)

4) configure opensips to use SQL
uncomment all lines in configuration file opensips.cfg which are related to authentication:
- loadmodule "/usr/lib/opensips/modules/db_mysql.so"
- loadmodule "/usr/lib/opensips/modules/auth.so"
- loadmodule "/usr/lib/opensips/modules/auth_db.so"
- modparam("usrloc", "db_mode", 2)
- modparam("auth", "calculate_ha1", yes)
- modparam("auth_db", "password_column", "password")
- if (!www_authorize("sip.org", "subscriber")) {
www_challenge("sip.org", "0");
break;

};

5) be sure to replace realm, the first parameter in www_* actions, with name of your server; some broken UAC implementations don't
authenticate otherwise; the authentication command in your configuration script should look then like this:
if (!www_authorize("myserver.foobar.com", "subscriber")) {
www_challenge("myserver.foobar.com", "0");
break;
}

6) restart the server
/etc/init.d/opensips restart

7) you can now start managing the server using the opensipsctl utility;
you need to first set the environment variable SIP_DOMAIN to your local SIP realm, e.g.,
export SIP_DOMAIN="myserver.foobar.com"
or you can configure via the resource file for opensipsctlrc. The default file is installed in the etc/ directory of your installation (along with the
OpenSIPS config file). For per user configuration, create .opensipsctlrc in your home directory.You can set there the values for opensipsctl variables like:
SIP_DOMAIN - your SIP domain
DBENGINE - database type: MYSQL, PGSQL or DBTEXT by default none is loaded
DBHOST - database host
DBNAME - database name
DBRWUSER - database read/write user
DBROUSER - database read only user
DBROPW - password for database read only user
DBROOTUSER - database super user
ALIASES_TYPE - type of aliases used:
DB - database aliases
UL - usrloc aliases
default none
CTLENGINE - control engine: FIFO or UNIXSOCK
OSIPS_FIFO - path to FIFO file
VERBOSE - verbose - debug purposes - default '0'

a) watch the server status using 'opensipsctl moni'
b) try to login with your SIP client as user 'admin' with
password 'opensipsrw'
c) try adding new users using
'opensipsctl add <name> <password> <email>'

8) default values (database url, users and passwords) are:
- db_default_url="mysql://opensips:opensipsrw@localhost/opensips"
- r/w user: opensips ; passwd: opensipsrw
- r/o user: opensipsro ; passwd: opensipsro
VERY IMPORTANT NOTE: for security reasons, do change the values of
passwords after installation

E) osipsconsole installation

1) Perl requirements

For the osipsconsole tool the following perl modules are needed:

DBI
DBD::mysql
DBD::Pg
DBD::Oracle
BerkeleyDB
Frontier::RPC2

2) Debian/Ubuntu Installation

In order for the script to work, there are listed bellow the modules
needed and their debian package correspondent, a brief description of each
package and whether it is mandatory to install it or not. ( To be mentioned
the fact that these packages have been tested in Debian and Ubuntu
distros. )

Perl module | Debian Package | Description | Use
---------------------------------------------------------------------------
perl |perl |Practical Extraction | mandatory
| |and Report Language |

DBI |libdbi-perl |Perl database interface| mandatory

DBD::mysql |libdbd-mysql-perl |MySQL driver for the |*optional
| |Perl5 DBI |

DBD::Pg |libdbd-pg-perl |PostgreSQL database |*optional
| |driver for DBI module |

**DBD::Oracle | ------ |Oracle database driver |*optional
| |for the DBI module |

Frontier::RPC2 |libfrontier-rpc-perl |encode/decode RPC2 | mandatory
| |format XML |

Term::ReadLine::Gnu|libterm-readline-gnu-per|Perl extension for the | mandatory
| |GNU Readline/History Lib|

BerkeleyDB |libberkeleydb-perl |Perl extension for | mandatory
| |Berkeley database |
| |version 2, 3 or 4 |


Install these packages using apt-get:

apt-get install perl libdbi-perl libdbd-mysql-perl libdbd-pg-perl
libfrontier-rpc-perl libterm-readline-gnu-perl
libberkeleydb-perl

NOTE: * packages are at the user's choice. At least one of them is
mandatory, depending on the DB type used by OpenSIPS. The other
ones have no need of being installed.
** For the DBD::Oracle module there is no debian package. This
will be installed as follows:
- Download the .tar.gz archive from:
http://search.cpan.org/~pythian/DBD-Oracle-1.22/Oracle.pm
- Decompress and unpack it
- cd DBD-Oracle-1.22
- perl Makefile.PL
- make
- make test
- make install


4. Troubleshooting
------------------

Q: SIP requests are replied by opensips with "483 Too Many Hops" or
"513 Message Too Large"

A: In both cases, the reason is probably an error in request routing script
which caused an infinite loop. You can easily verify whether this happens
by watching SIP traffic on loopback interface. A typical reason for
misrouting is a failure to match local domain correctly. If a server fails
to recognize a request for itself, it will try to forward it to current URI
in believe it would forward them to a foreign domain. Alas, it forwards the
request to itself again. This continues to happen until value of
max_forwards header field reaches zero or the request grows too big.
Solutions is easy: make sure that domain matching
is correctly configured. A quick way to achieve that is to introduce a config
option to opensips.cfg: alias=domainname, where domainname shall be replaced
with name of domain, which you wish to server and which appears in
request-URIs.
