Haproxy+keepalived实现sphinx高可用负载均衡

Haproxy+keepalived实现sphinx高可用负载均衡 环境如下： 【node3】 haproxy：192.168.1.189 【node4】 haproxy：192.168.1.103 vip：192.168.1.222/192.168.1.223 # apt-get install ipvsadm # apt-get install linux-headers-$(uname -r) # ln -s /usr/src/linux-headers-2.6.32-33 /usr/src/linux # wget http://www.keepalived.org/software/keepalived-1.2.2.tar.gz # tar zxvf keepalived-1.2.2.tar.gz -C ../software/ # ./configure --prefix=/usr/local/keepalived-1.2.2 configure: error:!!!
