Centos7安装Freeswitch并加载mod_ilbc_freeswitch 自动载入mod

系统：centos 7 1611 64
freeSWITCH版本：1.6.14 64

一、安装FreeSWITCH
1.下载源代码

wget http://files.freeswitch.org/freeswitch-releases/freeswitch-1.6.14.tar.gz
1

2.编译
运行 ./devel_bootstrap.sh
如果会出现类似autoconf not found错误提示，是因为没有下载第三方依赖库。
freeswitch依赖的第三方库有：gcc-c++ ，wget alsa-lib-devel， autoconf ，automake ，bison ，broadvoice-devel ，bzip2 ，curl-devel， db-devel ，e2fsprogs-devel， flite-devel ，g722_1-devel， gdbm-devel， gnutls-devel ，ilbc2-devel ，ldns-devel ，libcodec2-devel ，libcurl-devel ，libedit-devel ，libidn-devel ，libjpeg-devel， libmemcached-devel， libogg-devel ，libsilk-devel，libsndfile-devel ，libtiff-devel ，libtheora-devel， libtool， libvorbis-devel ，libxml2-devel ，lua-devel ，lzo-devel ，mongo-c-driver-devel， ncurses-devel， net-snmp-devel ，openssl-devel ，opus-devel ，pcre-devel ，perl perl-ExtUtils-Embed pkgconfig portaudio-devel ，postgresql-devel， python26-devel ，python-devel ，soundtouch-devel，speex-devel， sqlite-devel ，unbound-devel， unixODBC-devel ，libuuid-devel ，which yasm zlib-devel

3.安装依赖库：
（1）可以一个个安装，如下：

yum install autoconf
yum install automake 
yum install libtool 
……

（2）也可以全部一起安装：

yum install -y git gcc-c++ wget alsa-lib-devel autoconf automake bison broadvoice-devel bzip2 curl-devel db-devel e2fsprogs-devel flite-devel g722_1-devel gdbm-devel gnutls-devel ilbc2-devel ldns-devel libcodec2-devel libcurl-devel libedit-devel libidn-devel libjpeg-devel libmemcached-devel libogg-devel libsilk-devel libsndfile-devel libtiff-devel libtheora-devel libtool libvorbis-devel libxml2-devel lua-devel lzo-devel mongo-c-driver-devel ncurses-devel net-snmp-devel openssl-devel opus-devel pcre-devel perl perl-ExtUtils-Embed pkgconfig portaudio-devel postgresql-devel python26-devel python-devel soundtouch-devel speex-devel sqlite-devel unbound-devel unixODBC-devel libuuid-devel which yasm zlib-devel

4.再一次编译
运行 ./devel_bootstrap.sh
接着运行 ./configure
如果出现以下界面，就是默认配置成功.

5.选择安装的模块
编辑freeswitch-1.6.14/modules.conf 文件去掉模块前的”#”限可增加相应模块

[root@Freeswitch freeswitch]# more modules.conf 
    #applications/mod_abstraction
    #applications/mod_av
    #applications/mod_avmd
    #applications/mod_bert
    #applications/mod_blacklist
    #applications/mod_callcenter
    #applications/mod_cidlookup
    #applications/mod_cluechoo
    applications/mod_commands
    applications/mod_conference
    #applications/mod_curl
    #applications/mod_cv
    applications/mod_db

注：加载mod_ilbc时不需要配置modules.conf使之加载，因为配置了也不会编译成功，会报找不到libilbc-devel。而且centos 7中yum install libilbc-devel不成功（找不到相关），用源码编译出libilbc.so还是会提示找不到libilbc-devel。解决办法往下看。

6.运行 make 命令
如果出现以下界面，则编译成功。

7.安装
运行make install命令，缺省安装目录/usr/local/freeswitch/
如果出现以下界面，则安装成功。

8.启动freeswitch
进入cd /usr/local/freeswitch/bin/目录，然后运行 ./freeswitch命令。
如果出现以下界面，则运行成功。

二、加载mod_ilbc
freeswitch 要加载mod_ilbc就得有mod_ilbc.so和mod_ilbc.la。
mod_ilbc.so依赖libilbc.so。

1.编译libilbc.so

[root@localhost ~]# cd /root/freeswitch-1.6.14/libs/ilbc
[root@localhost ilbc]# aclocal
[root@localhost ilbc]# autoconf
[root@localhost ilbc]# Autoheader
[root@localhost ilbc]# libtoolize --automake --copy --debug --force
[root@localhost ilbc]# automake --add-missing(生成configure文件)
[root@localhost ilbc]# ./configure
[root@localhost ilbc]# make
1

验证是否生成libilbc.so

2.编译mod_ilbc.so
i. 从FreeSWITCH1.4.4中拷贝mod_ilbc.la（从Google得知1.4版本还可以加载mod_ilbc，但是mod_ilbc.so不可用）

 [root@localhost mod]# vim mod_ilbc.la
    # mod_ilbc.la - a libtool library file
    # Generated by libtool (GNU libtool) 2.4.2 Debian-2.4.2-1.1
    #
    # Please DO NOT delete this file!
    # It is necessary for linking the library.

    # The name that we can dlopen(3).
    dlname='mod_ilbc.so'

    # Names of this library.
    library_names='mod_ilbc.so mod_ilbc.so mod_ilbc.so'

    # The name of the static archive.
    old_library=''

    # Linker flags that can not go in dependency_libs.
    inherited_linker_flags=' -pthread'

    # Libraries that this one depends upon.
    dependency_libs=' /usr/local/freeswitch/lib/libfreeswitch.la -L/root/freeswitch-1.4.4/libs/apr-util/xml/expat/lib /usr/local/freeswitch/lib/libexpat.la /us
    r/local/freeswitch/lib/libapr-1.la -lpthread -lsqlite3 -lcurl -lpcre -lspeex -lspeexdsp -ledit -ltinfo -ldl -lcrypt -lrt -lz -lm -lssl -lcrypto -ljpeg'
    # Names of additional weak libraries provided by this library
    weak_library_names=''

    # Version information for mod_ilbc.
    current=0
    age=0
    revision=0

    # Is this an already installed library?
    installed=yes

    # Should we warn about portability when linking against -modules?
    shouldnotlink=yes

    # Files to dlopen/dlpreopen
    dlopen=''
    dlpreopen=''

    # Directory that this library needs to be installed in:
    libdir='/usr/local/freeswitch/mod'

ii. 找到一个与freeswitch-1.6.14 版本相近的freeswitch专用ilbc rpm包

wget --no-check-certificate https://rpmfind.net/linux/mageia/distrib/cauldron/x86_64/media/core/release/freeswitch-codec-ilbc-1.6.19-3.mga7.x86_64.rpm

从其中拷贝mod_ilbc.so

3.解决mod_ilbc的依赖

[root@localhost mod]# ldd mod_ilbc.so | grep not
    libfreeswitch.so.1 => not found
    libpng16.so.16 => not found
    libssl.so.1.0.0 => not found
    libcrypto.so.1.0.0 => not found
    libtinfo.so.6 => not found

i. 查找是否已有.so却找不到，还是.so是别的名字

[root@localhost ~]# find /usr/ -iname *libfreeswitch*so*
    /usr/local/freeswitch/lib/libfreeswitch.so.1.0.0
    /usr/local/freeswitch/lib/libfreeswitch.so.1

ii. 如果有*.so，增加动态库所在目录（方案一）
在/etc/ld.so.conf中增加动态库所在目录
ldconfig使配置生效

iii. 如果有.so，将相关.so修改文件名拷贝到/usr/lib64下（方案二）

[root@localhost ~]# cp /usr/local/freeswitch/lib/libfreeswitch.so.1 /usr/lib64/libfreeswitch.so.1
[root@localhost ~]# cp /usr/lib64/libpng15.so.15 /usr/lib64/libpng16.so.16
[root@localhost ~]# cp /usr/lib64/libssl.so.10 /usr/lib64/libssl.so.1.0.0
[root@localhost ~]# cp /usr/lib64/libcrypto.so.10 /usr/lib64/libcrypto.so.1.0.0
[root@localhost ~]# cp /usr/lib64/libtinfo.so /usr/lib64/libtinfo.so.6

4.加载mod_ilbc
启动FreeSWITCH

[root@localhost ~]# cd /usr/local/freeswitch/bin/
[root@localhost bin]# ./freeswitch 
[root@localhost bin]# ./fs_cli

5.验证编码格式

6.目前mod_ilbc是手动加载方式。若想自动加载如下所示。
[root@localhost ~]# vim /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml

三、验证
1.配置iLBC编码格式

[root@localhost ~]# vim /usr/local/freeswitch/conf/vars.xml
1

2.使用linphone配置ilbc编码，亲测有效。

注：可以去我的资源下载mod_ilbc.la和mod_ilbc.so文件
