keepalived-1.3.5的下载地址为 http://keepalived.org/software/keepalived-1.3.5.tar.gz

一  首先安装依赖和编译器

yum -y update kernel kernel-headers   #升级内核
reboot #重新启动电脑
yum -y install gcc make kernel-devel 
yum -y install curl libnl3-devel iptables-devel libnfnetlink-devel \
ipset-devel openssl-devel net-snmp-devel

二 编译keepalived

#安装在/usr/local/keepalived目录
./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/`uname -r`
make

三  安装keepalived

make install
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
ln -s /usr/local/keepalived/sbin/keepalived /usr/sbin/
touch /etc/init.d/keepalived
chmod +x /etc/init.d/keepalived
vi /etc/init.d/keepalived

keepalived的脚本内容如下

#!/bin/sh
#
# keepalived   High Availability monitor built upon LVS and VRRP
#
# chkconfig:   - 86 14
# description: Robust keepalive facility to the Linux Virtual Server project \
#              with multilayer TCP/IP stack checks.

prog="keepalived"

[ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog

lockfile=/var/lock/subsys/keepalived

start() {
    [ -x $exec ] || exit 5
    [ -e $config ] || exit 6
    echo -n $"Starting $prog: "
    daemon $exec $KEEPALIVED_OPTIONS
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    stop
    start
}

reload() {
    echo -n $"Reloading $prog: "
    killproc $prog -1
    retval=$?
    echo
    return $retval
}

force_reload() {
    restart
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status &>/dev/null
}


case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
        exit 2
esac
exit $?

四 配置和运行keepalived

配置keepalived.conf可参考lvs负载均衡-DR模式keepalived主备服务器配置

 vi /etc/keepalived/keepalived.conf #配置正确
 chkconfig --add keepalived
 chkconfig keepalived on
 service keepalived start

五 查看keepalived运行日志

more /var/log/messages |grep -E "\\[" |grep keepalived
