Centos 7 下安装opensips详细流程

1.mysql安装（因opensips添加鉴权用户需使用mysql存储）
<下载资源文件都放在 /usr/src/为例>
命令：

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install mysql-community-server

安装后启动：

service mysqld restart

登陆mysql：

mysql -u root 

修改密码：

set password for 'root'@'localhost' =password('password***');

注：最好不要修改mysql端口。

2.安装opensips

安装依赖库：

yum install mysql mysql-server mysql-libs mysql-devel
yum install gcc make
yum install flex bison ncurses libncurses-dev ncurses-devel

下载并解压opensips的源码（最新版本2.4.3，如果发现版本已更新可以去官网查看最新版本路径）：

cd /usr/src
 wget http://opensips.org/pub/opensips/latest/opensips-2.4.3.tar.gz
 tar zxvf opensips-2.4.3.tar.gz
 cd opensips-2.4.3

切换到root用户：

su

启动配置菜单：

make menuconfig

重点：很多教程都没表明这个选择步骤：Configure Compile Options -> Configure Excluded Modules -> db_mysql
按照此顺序选择db_mysql （空格键为选择键方向键为前进后退和确定）
选择db_mysql后一定要save。
最后选择”Compile And Install Opensips” 等待安装完毕。

安装完成后：

 cd /usr/local/etc/opensips/
 vi opensipsctlrc

编辑配置数据库信息：（需要修改的要按照自己情况修改比如 host password等）

SIP_DOMAIN= YOUR_PC_IP   //此处写本机地址，如果有代理填写proxy地址
#数据库 MYSQL ORACLE PGSQL DB_BERKELEY DBTEXT均可

DBENGINE=MYSQL

#数据库所在服务器主机名/IP均可

DBHOST=localhost

#数据库名称，默认使用opensips，可配置其它名称

DBNAME=opensips

#数据库访问用户，主要用于数据的读写，请在mysql添加用户

DBWUSER=opensips

#数据库访问密码，密码必须为DBWUSER对应用户的密码

DBWPW=“123456”

#数据库管理用户，用于数据库、表创建与数据读写等，默认使用root，如有需要可以自行配置mysql用户权限

DBROOTUSER=“root”

配置opensips：

cd /usr/local/sbin/
osipsconfig

依次选择–> Generate OpenSIPS Script –> Residential Script–> Configure Residential Script
选中（选择键为空格键）

[*] USE_AUTH
[*] USE_DBACC
[*] USE_DBUSERLOC
[*] USE_DIALOG

返回，选择 –> Generate Residential Script 回车，生成新的配置文件（在/usr/local/etc/opensips/目录下）
拷贝和替换原有配置文件：

cd /usr/local/etc/opensips/
mv opensips.cfg opensips.cfg.old
mv opensips_residential_2018-5-3_1\:13\:3.cfg opensips.cfg

修改opensips.cfg

vi opensips.cfg

listen=udp:127.0.0.1:5060 修改为listen=udp:本机ip:5060

修改完数据库配置后使用opensipsdbctl新建数据库：

cd /usr/local/sbin
opensipsdbctl create

增加用户（add后第一个是用户名第二个是密码）：

opensipsctl add 101 101
opensipsctl add 102 102

启动opensipsctl

opensipsctl start

此时可以使用sip客户端检查下server运行情况。

error：
1.opensipsdbctl create 时出现：

ERROR: could not load the script in /usr/local//lib64/opensips/opensipsctl/opensipsdbctl.mysql for database engine MYSQL
ERROR: database engine not loaded - tried 'MYSQL'

因为没有在配置make menuconfig时选择db_mysql可以使用以下命令或者重新做一次配置。

     cd /usr/local/lib/opensips/opensipsctl/
     cp 你的opensips目录/scrips/opensipsdbctrl.mysql  ./
     mkdir mysql
     cp  你的opensips目录/scrips/mysql/*.sql ./

2.启动opensips后抓包发现服务器返回sip 408 Request Timeout。
修改

 cd /usr/local/etc/opensips/
 vi opensipsctlrc

编辑配置数据库信息：（需要修改的要按照自己情况修改比如 host password等）

SIP_DOMAIN= YOUR_PC_IP   //此处写本机地址

3.启动时候出现

ERROR: PID file /var/run/opensips.pid does not exist -- OpenSIPS start failed

检查/var/log/messages
具体的指令:tail -100 /var/log/messages

解决方法：

打开mysql

mysql -u root -p
mysql> grant all privileges on opensips.* to opensips@localhost identified by 'opensipsrw';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

重新启动OpenSIPS
目录（cd /usr/local/sbin）

opensipsctl start
