For CentoOS

yum groupinstall "Development Tools"
yum install ncurses-devel.x86_64 libmicrohttpd-devel.x86_64 openssl openssl-devel.x86_64

2. Download latest opensips from www.opensips.org or for opensips-1.10beta use the following command

$ wget http://opensips.org/pub/opensips/latest/src/opensips-1.10_src.tar.gz

3. Use "tar -zxvf" to extract opensips tar file

$ tar -zxvf opensips-1.10_src.tar.gz

4. go into the directory

$ cd opensips-1.10.0beta-tls

5. make the configuration file

$ make menuconfig
--> Configure Compile Options

--> Save Changes
--> Compile And Install OpenSIPS
--> Exit & Save All Changes

7. If you want to configure opensips with Database then do the changes in the following file

$ vim /usr/local/etc/opensips/opensipsctlrc

# If you want to setup a database with opensipsdbctl, you must at least specify
# this parameter.
DBENGINE=MYSQL

## database host
DBHOST=localhost

## database name (for ORACLE this is TNS name)
DBNAME=opensips

# database path used by dbtext or db_berkeley
# DB_PATH="/usr/local/etc/opensips/dbtext"

## database read/write user
DBRWUSER=opensips

## password for database read/write user
DBRWPW="opensips"

8. Go to Install prefix directory /usr/local/sbin/

$ ./opensipsdbctl create
$ ./opensipsctl start
