Let’s Begin…

apt-get install build-essential openssl bison flex
apt-get install perl libdbi-perl libdbd-mysql-perl libdbd-pg-perl libfrontier-rpc-perl libterm-readline-gnu-perl libberkeleydb-perl ncurses-dev
apt-get install mysql-server libmysqlclient-dev
wget http://opensips.org/pub/opensips/latest/opensips-2.3.0.tar.gz
tar -xvf opensips-2.3.0.tar.gz
cd opensips-2.3.0/
make all
make install 
mkdir /var/run/opensips
cd packaging/debian/
cp opensips.default /etc/default/opensips
cp opensips.init /etc/init.d/opensips
chmod +x /etc/init.d/opensips
useradd opensips
update-rc.d opensips defaults 99

vim /etc/default/opensips
Here you need to replace the 'RUN_OpenSIPS' to 'Yes'. You can also change the user and group and name that you wish to use for the Opensips services and also change the shared memory to minimum 128 which is recommended for the OpenSIPS server.

we also need to update the daemon on OpenSIP and change it location in its startup script and update its state from ‘off’ to ‘on’ and then close the file after making changes.
