安裝預裝好的 CentOS 5.5 AMI (ami-eb807682: CentOS5.5 i386 10G)
Install all packages(rpm) of Elastix
Download Elastix ISO
http://www.elastix.org/en/downloads/main-distro.html
Prerequisties before intallation starting
cd /mnt
wget http://sourceforge.net/projects/elastix/files/Tools/Cent2Elastix%20%28CentOS%205.4%20to%20Elastix%201.6%20stable%29/ElastiXCorE-1.6-i386-22dec2009.iso/download
mkdir ISO/
mount -o loop ElastiXCorE-1.6-i386-22dec2009.iso ISO/
I modified the official install script to be able to complete the installation of all rpms on EC2.
Turn off firewall
service iptables stop setenforce 0
Install kernel package
註：必須安裝 ISO 內的 kernel-2.6.18-164 及 kernel-xen-2.6.18-164，其餘版本不可使用。
yum remove kernel yum remove kernel-xen cd /mnt/ISO rpm -ivh CentOS/kernel-2.6.18-164.el5.i686.rpm rpm -ivh CentOS/kernel-xen-2.6.18-164.el5.i686.rpm vi /etc/yum.repos.d/ElastixCore.repo
ElastixCore.repo:
[elastix-core] name=Elastix RPM Repository for CentOS baseurl=file:///mnt/ISO/Elastix gpgcheck=0 enabled=1 [epel-elastix] name=EPEL RPM dependencies for Elastix baseurl=file:///mnt/ISO/epel gpgcheck=0 enabled=1
Install Elastix Core
service yum-updatesd stop yum clean all yum groupupdate "Epel Elastix" yum groupupdate "Elastix Core" rm -f /etc/yum.repos.d/ElastixCore.repo
Clean up and reboot
rm -f /etc/yum.repos.d/ElastixCore.repo umount /mnt/ISO reboot
Compile and install dahdi_dummy module
// Install gcc-4.0.2
cd /usr/src wget http://ftp.gnu.org/gnu/gcc/gcc-4.0.2/gcc-4.0.2.tar.bz2 tar -xjf gcc-4.0.2.tar.bz2 cd gcc-4.0.2 mkdir tmp cd tmp ../configure --program-suffix=-4.0.2 make make install
The above will take 20+ minutes, so take a break let's enjoy a coffee.
