lang110

yum -y install gcc gcc-c++ kernel-devel libnl* popt*
mkdir /usr/local/src/lvs
cd /usr/local/src/lvs
wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.26.tar.gz
ln -s /usr/src/kernels/2.6.32-358.11.1.el6.i686/ /usr/src/linux
tar zxvf ipvsadm-1.26.tar.gz
cd ipvsadm-1.26
make
make install
　　lvs启动脚本 lvs.sh

exit 1
else
echo "ipvsadm OK"
fi

echo "Usage: $0 {start|stop|status}"
　　　　　　　　　　　　　　exit 1
