首先选择合适版本，查看uname -a或者-r
打开 ，选择相应版本下载，一般下载tar包
解压，进入后make，make install
如果报错
[root@nginx-test ipvsadm-1.24]# make
make -C libipvs
make[1]: Entering directory `/root/ipvsadm-1.24/libipvs'
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include  -DHAVE_NET_IP_VS_H -c -o libipvs.o libipvs.c
在包含自 libipvs.c：23 的文件中:
libipvs.h:14:23: 错误：net/ip_vs.h：没有那个文件或目录
In file included from libipvs.c:23:

……
 
是因为找不到内核，yum install kernel-devel
ln -s /usr/src/kernels/2.6.18-194.26.1.el5-i686 /usr/src/linux
然后make clean
make
make install
