系统centos 7

1、安装ipvsadm-1.26.tar.gz 下载地址：[http://www.linuxvirtualserver.org/software/ipvs.html][http_www.linuxvirtualserver.org_software_ipvs.html]

2、需要安装gcc，libnl\* libpopt\*，popt-static，使用yum安装，yum install gcc libnl\* libpopt\* popt-static

3、出现错误：

make[1]: Entering directory `/opt/ipvsadm/libipvs'
    gcc -Wall -Wunused -Wstrict-prototypes -g -fPIC -DLIBIPVS_USE_NL  -DHAVE_NET_IP_VS_H -c -o libipvs.o libipvs.c
    In file included from libipvs.h:13:0,
                     from libipvs.c:23:
    ip_vs.h:15:29: fatal error: netlink/netlink.h: No such file or directory
     #include <netlink/netlink.h>
                                 ^
    compilation terminated.

说明ip\_vs模块没有被加载，使用lsmod | grep ip\_vs是否有显示

使用modprobe ip\_vs 将模块加载进来

进入ipvs目录，安装 make && make install

运行命令:ipvsadm，查看是否安装成功

4、安装 keepalived-1.2.23.tar.gz,下载地址：[http://www.keepalived.org/download.html][http_www.keepalived.org_download.html]

> 安装openssl libnfnetlink，yum install openssl openssl-devel libnetfilter\_queue **libnfnetlink-devel**  
>

5、安装keepalive

>     ./configure --prefix=/usr/local/keepalived
> 
>   
> 
> 
>     make  && make install

>   
> 
> 
>     cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
>     cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
>     mkdir /etc/keepalived
>     cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
>     cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
> 
>
