使用de环境：
VMware虚拟环境下的Red hat enterprise linux
(其他版本也可以，安装时对于新手，建议软件包全部安装，避免后期有好多工具都没有。避免补安装时会出现连锁的问题，这个很麻烦)
版本：
前期准备：
LINUX基本指令的熟悉
Mysql：我们选用的数据库，使用系统自带的mysql就可以，注意安装系统时选上mysql安装包。
mysql一些指令：
show databases；
use opensips；
show tables；
select * from subscribers；
drop；
create；
and so on；
Opensips的安装:
2、 编译：
tar zxvf opensips-1.4.3-tls_src.tar.gz
cd opensips-1.4.3-tls
3、安装之前更改makefile：
删除Makefile中的exclude_modules 的db-mysql ，为了使opensips支持mysql。
4、 安装
make all
make install
默认安装路径/usr/local下
5、 创建opensips的数据库
vi /usr/local/opensips/etc/opensips/opensipsctlrc 把mysql的相关的注释去掉
## database type: MYSQL, PGSQL, ORACLE, DB_BERKELEY, or DBTEXT, by default none is loaded
# 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="opensipsrw"
## database read only user
DBROUSER=opensipsro
## password for database read only user
DBROPW=opensipsro
## database super user (for ORACLE this is 'scheme-creator' user)
DBROOTUSER="root"
# user name column
USERCOL="username"
执行opensips/sbin/下的opensipsdbctl
./opensipsdbctl create (生成opensips数据库)
5.opensips的运行
opensips/sbin/下的opensipsctl start来启动opensips
ps -efw opensips 检查应该已经运行了。
opensips/sbin/下的opensipsctl stop来停止opensips
到此完成了opensips的安装。

为实现注册和认证功能，除了配置好opensips.cfg,还需改动opensipsctl中的一些地方，记录如下：
默认文档中为：
## path to FIFO file
OSIPS_FIFO="FIFO" (路径不对)
改为：
OSIPS_FIFO="/tmp/opensips_fifo"
运行：
1、运行mysql：
Service mysqld start
2、开启opensips：
opensipsctl restart
3、configure two users accounts.(格式：opensipsctl add user password)
opensipsctl add 1001 1001
opensipsctl add 1002 1002
注：opensipsctl rm -------remove users
opensipsctl passwd-----change a password
4、 用已有用户和密码注册两个sip softphone（我用的X-lite和eyebeam）
5、 检查是否注册成功
opensipsctl ul show
6、 检查是否在线
opensipsctl online
注：两个sip softphone注册必须使用数据库中已有的用户名和密码，否则将不能通过认证。
7、make a call from one phone to the other。
