asterisk官网有安装的具体步骤和教程，这里我主要参考官网中的源码安装方式。链接

1、关闭SELinux、防火墙

sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/sysconfig/selinux

service iptables stop

2、系统更新

yum install -y epel-release

yum update -y

3、安装依赖库和附加服务

yum install -y gcc gcc-c++ lynx bison mysql-devel mysql-server php php-mysql php-pear php-mbstring tftp-server httpd make ncurses-devel libtermcap-devel sendmail sendmail-cf caching-nameserver sox newt-devel libxml2-devel libtiff-devel audiofile-devel gtk2-devel subversion kernel-devel git subversion kernel-devel php-process crontabs cronie cronie-anacron wget vim php-xml uuid-devel libtool sqlite-devel unixODBC mysql-connector-odbc

4、下载：

1)asterisk：

cd /usr/local/scr/

wget https://downloads.asterisk.org/pub/telephony/asterisk/asterisk-14-current.tar.gz

2)libpri：

You'll only need this if you are going to use DAHDI with ISDN interface hardware (such as T1/E1/J1/BRI cards).

wget http://downloads.asterisk.org/pub/telephony/libpri/old/libpri-1.5.0.tar.gz3)DAHDI：

cd /usr/local/src/

wget https://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz

注：启动dahdi时会遇到一个问题，dahdi: unrecognized service，原因是版本太高了，后来选择了一个旧版本的就可以了。

cd /usr/local/src/

wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-2.6.0+2.6.0.tar.gz587

tar zxvf dahdi-linux-complete-2.6.0+2.6.0.tar.gz

cd dahdi-linux-complete-2.6.0+2.6.0

make all

make install

make config

/etc/init.d/dahdi restart

chkconfig dahdi on

1)首先，在编译以上这些源码的时候，可能会报一些错，需要安装一下依赖：

A、You do not appear to have the sources for the.x86_64 kernel installed.

yum install "kernel-devel-uname-r == $(uname -r)"

B、g++: Command not found:

yum -y update gcc

yum -y install gcc+ gcc-c++

2)编译、安装libpri：

tar xzvf libpri-1.5.0.tar.gz

cd /usr/src/libpri-1.5.0

make

make install

3)编译、安装dadhi：

如上

4)编译、安装jpsip：

git clone https://github.com/asterisk/pjproject pjproject

unzip pjproject-master.zip

./configure --prefix=/usr --enable-shared --disable-sound --disable-resample --disable-video --disable-opencore-amr CFLAGS='-O2 -DNDEBUG'

make dep

make

make install

ldconfig

ldconfig -p | grep pj

注：可能会遇到这个问题：[libpjsua2-x86_64-unknown-linux-gnu.a] Error 2

deleting the pjproject folder, download it and finally run configure and make commands did the trick for me

5)编译asterisk：

cd /usr/local/src/asterisk-14.X.Y

./configure

在编译的时候会遇到很多问题：

A、提示： JSON support not found

解决：安装jansson

git clone https://github.com/akheron/jansson.git

unzip jansson-master.zip

cd jansson-master

autoreconf

这时可能汇报：centos -bash: autoreconf: command not found

yum -y install autoconf automake libtool

yum -y install libffi-dev

然后，再

./configure --libdir=/usr/lib64

make

make installB、configure: error: *** termcap support not found (on modern systems, this typically means the ncurses development package is missing)

yum -y install bison

yum -y install bison-devel

yum -y install ncurses

yum -y install ncurses-devel

yum -y install zlib

yum -y install zlib-devel

yum -y install openssl

yum -y install openssl-devel

yum -y install gnutls-devel

yum -y install gcc

yum -y install gcc-c++

C、 uuid support not found (this typically means the libjansson development package is missing)：

yum -y install uuid-devel

yum -y install libuuid libuuid-devel

D、configure: *** The Asterisk menuselect tool requires the 'libxml2' development package.

configure: *** Please install the 'libxml2' development package.

wget http://download.chinaunix.net/down.php?id=28493&ResourceID=6095&site=1

./configure

make

make install

E、configure: error: *** Asterisk now uses SQLite3 for the internal Asterisk database.

wget http://download.chinaunix.net/down.php?id=19777&ResourceID=9862&site=1

./configure

make

make install

各种问题的解决可以参考：http://blog.sina.com.cn/s/blog_7a3dc0c90102vwvu.html

编译成功后，会出现如下图案：

6)make menuselect

# make menuselect

7)安装asterisk：

make

make installmake的时候可能会失败

make[1]: *** [res_pjsip/config_transport.o] Error 1

make: *** [res] Error 2分析应该是pjsip的版本不对，然后重新下载高版本：

# cd /usr/src

# wget http://www.pjsip.org/release/2.3/pjproject-2.3.tar.bz2

# tar -jxvf pjproject-2.3.tar.bz2

cd pjproject-2.3

# ./configure CFLAGS="-DNDEBUG -DPJ_HAS_IPV6=1" --prefix=/usr --libdir=/usr/lib64 --enable-shared --disable-video --disable-sound --disable-opencore-amr

# make dep

# make

# make install

# ldconfig -p | grep pj

最后，在重新make asterisk。

make成功后会出现

make install成功后，会出现

8)安装sample：

# make samples这个时候，在/etc/asterisk目录下会建立一些文件，最主要的有sip.conf、extensions.conf 这两个。

9)运行asterisk：

# /usr/sbin/asterisk

# ps -ef | grep aste

root 4177 32476 0 19:09 pts/1 00:00:00 grep aste

root 4273 1 0 2016 ? 00:02:20 /usr/libexec/postfix/master

root 8742 1 0 Mar14 ? 00:03:42 /usr/sbin/asterisk
