安装步骤
- 安装必要软件：
yum -y install m4 gcc redhat-rpm-config xmlto asciidoc elfutils-libelf-devel binutils-devel newt-devel perl-ExtUtils-Embed hmaccalc rng-tools
- 下载源码
mkdir /home/lvs cd /home/lvs 去百度云盘下载220内核的ipvs和ip_vs.h上传到/home/lvs文件夹下 链接: https://pan.baidu.com/s/1miLp7BE 密码: wdh7 tar zxvf ipvs.tar.gz wget http://vault.centos.org/6.4/os/Source/SPackages/kernel-2.6.32-358.el6.src.rpm wget http://kb.linuxvirtualserver.org/images/a/a5/Lvs-fullnat-synproxy.tar.gz tar zxvf Lvs-fullnat-synproxy.tar.gz
- 编译内核重启

- 重启后加载驱动安装工具
modprobe ip_vs modprobe ip_vs_rr modprobe ip_vs_wrr modprobe ip_vs_sh modprobe iptable_filter modprobe ip_tables modprobe toa 安装工具 cd /home/lvs/lvs-fullnat-synproxy tar xzf lvs-tools.tar.gz cd tools cd keepalived/ ./configure --with-kernel-dir=”/lib/modules/`uname -r`/build” make make install cd /home/lvs/lvs-fullnat-synproxy/tools/ipvsadm/ make make install quagga可以 yum -y install quagga安装也可以编译安装 cd /home/lvs/lvs-fullnat-synproxy/tools/quagga ./configure make make install

最后附上编译好的rpm内核包，没有亲测过不确定完全没问题

总算把之前没完成的作业写完了，科科
感谢艺龙大神的方案，希望大家都能用上lvs_fullnat哈，有问题可以多讨论，有的好的方案欢迎大家多多留言
