To FreeSWITCH Users, Here are my instructions to install FreeSWITCH 1.6.5 on CentOS 6.7. Please note: Currently mod_fsv and mod_vpx (both are relating to FreeSWITCH video features) are not supported inside these instructions, however if you are wanting to move off 1.4.x (since this is going end-of-life in 2016 at some stage) then this could at least be a very good first step, especially if upgrading to Centos 7 is not possible based on your current environment setup. This is based on a fresh installation of CentOS 6.7 (CentOS-6.7-x86_64-bin-DVD1.iso). In my case I ran a default setup selecting Software Development Workstation. 1) Make sure yum update is run and CentOS is up-to-date 2) {optional} Inside Terminal window select Edit Profile Preferences and select "Use custom default terminal size" and make it 160 x 60. Close terminal and re-open for the change to take effect. 3) yum -y install epel-release 4) yum -y install git gcc-c++ autoconf automake libtool wget python ncurses-devel zlib-devel libjpeg-devel openssl-devel sqlite-devel libcurl-devel libxml2-devel libidn-devel 4.1) These should be already installed and up-to-date 5) yum -y install e2fsprogs-devel pcre-devel speex-devel ldns-devel libedit-devel libyuv-devel opus-devel libvpx-devel unbound-devel libuuid-devel lua-devel libsndfile-devel 5.1) These should install successfully 6) Note: No packages for: libvpx2*, libdb4* (so mod_vpx & mod_fsv will not be supported) 7) cd /usr/local/src 8) git clone -b v1.6 https://freeswitch.org/stash/scm/fs/freeswitch.git 9) cd /usr/local/src/freeswitch 10) ./bootstrap.sh 11) vi modules.conf 11.1) comment out (ie. place '#' infront): mod_fsv mod_vpx Save and close (<Esc> :wq!) 12) ./configure 13) make 14) make install 15) make cd-sounds-install 16) make cd-moh-install 17) cd /usr/local/freeswitch/conf 18) vi vars.xml 18.1) change: <X-PRE-PROCESS cmd="set" data="default_password=1234"/> { !! set it to something different !! } Save and close (<Esc> :wq!) 19) cd /usr/local/freeswitch/conf/autoload_configs 20) vi modules.conf.xml 20.1) comment out (ie. place '<!--' infront and '-->' at the end): mod_fsv mod_vpx Save and close (<Esc> :wq!) 21) cd /usr/local/freeswitch/bin 22) ./freeswitch -nonat -nonatmap 23) ... to exit from the FreeSWITCH console Version: FreeSWITCH Version 1.6.5+git~20151120T205750Z~70b8c17763~64bit (git 70b8c17 2015-11-20 20:57:50Z 64bit) Kind Regards, Andrew Keil Visytel Pty Ltd
