在之前，我们转载了FreeSWITCH官网上有关postgresql的配置的问题，但是在细节上并没有描述，现在就如何在debian8.1上安装FreeSWITCH、Postgresql并使用Postgresql作为FreeSWITCH数据库做个简单介绍。
第一步、安装Postgresql
CentOS 或debian 源码安装 PostgreSQL 9.3.5
安装PostgreSQL前，确认Internet连接正常，以便下载安装文件。
先使用 yum -y update 指令升级系统到最新版本。
本安装将PostgreSQL的数据文件与执行文件分离，如果你打算设置到不同的路径，注意修改对应的执行命令和数据库初始化脚本。
＃ 修改防火墙设置，打开5432端口
vi /etc/sysconfig/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 5432 -j ACCEPT
＃ 重启防火墙使新设置生效
service iptables restart
＃ 新增用户组
groupadd postgres
＃ 新增用户
useradd postgres -g postgres
＃ 新建数据库执行文件目录
mkdir -p /usr/local/pgsql
＃ 新建数据库数据文件目录
mkdir -p /db/pgsql/data
＃ 修改目录拥有者
chown -R postgres /usr/local/pgsql/.
chown -R postgres /db/pgsql/data
chown -R postgres /db/pgsql/data/.＃ 编辑PATH搜索路径
vi /etc/profileAppend these 2 lines to the end of the file:
PATH=/usr/local/pgsql/bin:$PATH
export PATH＃ 生效PATH搜索路径
source /etc/profile＃ 安装编译源码所需的工具和库
yum -y install wget gcc readline-devel zlib-devel makedebian
apt-get install zlibc libghc-zlib-dev libzlcore-dev gcc make git automake＃ 进入源码压缩包下载目录
cd /usr/src＃ 下载源码压缩包
wget http://ftp.postgresql.org/pub/source/v9.3.5/postgresql-9.3.5.tar.gz＃ 解压缩源码包
tar zxvf ./postgresql-9.3.5.tar.gz＃ 进入解压缩源码目录
cd ./postgresql-9.3.5＃ 执行源码编译配置脚本
./configure＃ 编译源码
make＃ 安装
make install＃ 变更登录用户
su - postgres＃ 执行数据库初始化脚本
/usr/local/pgsql/bin/initdb --encoding=utf8 -D /db/pgsql/data＃ 退出变更登录
exit＃ 复制PostgreSQL执行脚本
cp /usr/src/postgresql-9.3.5/contrib/start-scripts/linux /etc/init.d/postgresql＃ 增加执行权限
chmod +x /etc/init.d/postgresql＃ 编辑PostgreSQL执行脚本，指定数据库文件目录
vi /etc/init.d/postgresql
PGDATA="/db/pgsql/data"＃ 编辑配置文件，配置可访问数据库的网络地址 (注意别忘了去掉#listen_addresses=前面的#)
vi /db/pgsql/data/postgresql.conf
listen_addresses = '*'＃ 启动PostgreSQL服务
service postgresql start＃ 以postgres用户登录数据库，修改postgres用户的数据库密码
psql -U postgres
postgres=# ALTER USER postgres PASSWORD '123456';
postgres=# \q退出pg登录
exit＃ 编辑配置文件，设置密码md5验证
vi /db/pgsql/data/pg_hba.conf
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
#host all all 127.0.0.1/32 trust
host all all 0.0.0.0/0 md5＃ 重启数据库服务
service postgresql restartdebian下需要安装 chkconfig工具
设置开机自动启动服务
chkconfig postgresql on配置LD_LIBRARY_PATH vi /etc/profile
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib
export LD_LIBRARY_PATH
C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/pgsql/include
export C_INCLUDE_PATHsource /etc/profile
二、 安装FreeSWITCH
- 配置debian源
vim /etc/apt/sources.list
变成以下内容：
\# deb cdrom:[Debian GNU/Linux 8.1.0 _Jessie_ - Official amd64 DVD Binary-1 20150606-14:19]/ jessie contrib main
\# deb cdrom:[Debian GNU/Linux 8.1.0 _Jessie_ - Official amd64 DVD Binary-1 20150606-14:19]/ jessie contrib main
\# deb http://security.debian.org/ jessie/updates main contrib
\# deb-src http://security.debian.org/ jessie/updates main contrib
deb http://mirrors.163.com/debian jessie main non-free contrib
deb http://mirrors.163.com/debian jessie-proposed-updates main contrib non-free
deb http://mirrors.163.com/debian-security jessie/updates main contrib non-free
deb http://security.debian.org jessie/updates main contrib non-free
\# 以上禁掉cdrom和deb原生源，改为163的，加快速度
\# jessie-updates, previously known as 'volatile'
\# A network mirror was not selected during install. The following entries
\# are provided as examples, but you should amend them as appropriate
\# for your mirror of choice.
\#
\# deb http://ftp.debian.org/debian/ jessie-updates main contrib
\# deb-src http://ftp.debian.org/debian/ jessie-updates main contrib- 下载并编译 a. 添加freeswitch的源
echo "deb http://files.freeswitch.org/repo/deb/debian/ jessie main" > /etc/apt/sources.list.d/99FreeSWITCH.test.listwget -O - http://files.freeswitch.org/repo/deb/debian/key.gpg |apt-key add -apt-get update
b. 安装依赖 DEBIAN_FRONTEND=none APT_LISTCHANGES_FRONTEND=none apt-get install -y --force-yes freeswitch-video-deps-most
c. git FreeSWITCH的源码
git config --global pull.rebase true
git clone https://freeswitch.org/stash/scm/fs/freeswitch.git freeswitch.git
cd freeswitch.git
./bootstrap.sh -jd. 在modules.conf中开启pg_cdr vim modules.conf
去掉 mod_cdr_pg_csv 前的#
e. 编译并install
./configure --enable-core-pgsql-support
make
make install
make cd-sounds-install
make cd-moh-install
make samplesf. 配置FreeSWITCH使用Postgresql
<param name="odbc-dsn" value="pgsql://hostaddr=127.0.0.1 dbname=freeswitch user=postgres password='123456' options='-c client_min_messages=NOTICE' application_name='freeswitch'" />这就是置于FreeSWITCH中的pg配置
如db.conf.xml:
<configuration name="db.conf" description="LIMIT DB Configuration">
<settings>
<!--<param name="odbc-dsn" value="dsn:user:pass"/>-->
<param name="odbc-dsn" value="pgsql://hostaddr=127.0.0.1 dbname=freeswitch user=postgres password='123456' options='-c client_min_messages=NOTICE' application_name='freeswitch'" />
</settings>
</configuration>其余的配置文件如下：
db.conf.xml
fifo.conf.xml
voicemail.conf.xml
switch.conf.xml
internal.xml
external.xml配置cdr,先建立库及表
su - postgres
psql -U postgres
\#postgres> create database cdr;
\#postgres>
create table cdr (
id serial primary key,
local_ip_v4 inet not null,
caller_id_name varchar,
caller_id_number varchar,
destination_number varchar not null,
context varchar not null,
start_stamp timestamp with time zone not null,
answer_stamp timestamp with time zone,
end_stamp timestamp with time zone not null,
duration int not null,
billsec int not null,
hangup_cause varchar not null,
uuid uuid not null,
bleg_uuid uuid,
accountcode varchar,
read_codec varchar,
write_codec varchar,
sip_hangup_disposition varchar,
ani varchar
);
\#postgres>\q
exit修改pg_cdr.conf.xml文件中的db-info
<param name="db-info" value="host=localhost dbname=cdr user=postgres password=123456 connect_timeout=10" />那么基本数据库就会使用postgresql了，从而避免sqlite 文件破坏动不动让系统无法工作的问题。
