需要一个纯净的虚拟机，需要重新编译内核；为了提高编译速度，4CPU，2048内存。
内核源码 linux-2.6.32-220.23.1.el6.x86_64
使用dvd.repo做yum源
所需软件包：kernel-2.6.32-220.23.1.el6.src.rpm Lvs-fullnat-synproxy.tar.gz
解决依赖性：asciidoc-8.4.5-4.1.el6.noarch.rpm newt-devel-0.52.11-3.el6.x86_64.rpm slang-devel-2.2.1-1.el6.x86_64.rpm
rpm -ivh kernel-2.6.32-220.23.1.el6.src.rpm yum install -y rpm-build uname -r
cd rpmbuild/SPECS/ yum install -y gcc redhat-rpm-config patchutils xmlto asciidoc elfutils-libelf-devel zlib-devel binutils-devel newt-devel python-devel perl-ExtUtils-Embed hmaccalc cd yum install asciidoc-8.4.5-4.1.el6.noarch.rpm newt-devel-0.52.11-3.el6.x86_64.rpm slang-devel-2.2.1-1.el6.x86_64.rpm -y rpmbuild -bp kerbel.spec ##较长时间，可通过rngd -r /dev/urando解决（安装 rngd-tools）
cd /root/rpmbuild/BUILD/kernel-2.6.32-220.23.1.el6/ tar zxf Lvs-fullnat-synproxy.tar.gz cd lvs-fullnat-synproxy/ cp lvs-2.6.32-220.23.1.el6.patch ../linux-2.6.32-220.23.1.el6.x86_64/ cd .. cd linux-2.6.32-220.23.1.el6.x86_64/ yum install -y patch patch -p1 < lvs-2.6.32-220.23.1.el6.patch vim .config vim Makefile uname -r cd configs/ diff kernel-2.6.32-x86_64.config ../.config
增加一个20G的虚拟硬盘
fdisk -cu /dev/vdc pvcreate /dev/vdc1 vgextend VolGroup /dev/vdc1 lvextend -L +20G /dev/VolGroup/lv_root lvextend -l +5119 /dev/VolGroup/lv_root resize2fs /dev/VolGroup/lv_root df -h

uname -r ##2.6.32-220.23.1.el6
cd rpmbuild/BUILD/kernel-2.6.32-220.23.1.el6/lvs-fullnat-synproxy/ cp lvs-tools.tar.gz /root tar zxf lvs-tools.tar.gz cd tools/keepalived/ yum install openssl-devel popt-devel -y ./configure --with-kernel-dir="/lib/modules/`uname -r`/build" make make install which keepalived cd .. cd ipvsadm/ yum install -y ipvsadm make make install ipvsadm --help ipvsadm -l
所需软件包：crmsh-1.2.6-0.rc2.2.1.x86_64.rpm pssh-2.3.1-2.1.x86_64.rpm
使用有集群环境的虚拟机
先确定有没有其它软件在运行
【server1】
ps ax ##将cman等服务关掉

rpm -q corosync /etc/init.d/keepalived status /etc/init.d/heartbeat status /etc/init.d/cman status ##没关掉的关掉
