Ubuntu14.04 Keepalived安装

记录安装过程

1，预装编译环境

sudo apt-get install -y gcc
sudo apt-get install -y g++
sudo apt-get install -y libssl-dev
sudo apt-get install -y daemon
sudo apt-get install -y make

2,下载keepalived

cd /usr/local/
wget http://www.keepalived.org/software/keepalived-1.2.18.tar.gz

3,编译安装keepalived

tar zxvf keepalived-1.2.18.tar.gz

cd keepalived-1.2.18

./configure --prefix=/usr/local/keepalived

make && make install

4,将keepalived设置为系统服务

mkdir /etc/keepalived
mkdir /etc/sysconfig
cp /usr/local/keepalived/etc/keepalived/keepalived.conf  /etc/keepalived/
cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
ln -s /usr/local/sbin/keepalived /usr/sbin/
ln -s /usr/local/keepalived/sbin/keepalived /sbin/

5,修改keepalived启动的配置文件,因为除Readhat之外的linux没有/etc/rc.d/init.d/functions,所以需要修改原来的启动文件

将 . /etc/rc.d/init.d/functions 修改为 . /lib/lsb/init-functions
将 daemon keepalived ${KEEPALIVED_OPTIONS} 修改为 daemon keepalived start

修改后整体内容如下

#!/bin/sh
#
# Startup script for the Keepalived daemon
#
# processname: keepalived
# pidfile: /var/run/keepalived.pid
# config: /etc/keepalived/keepalived.conf
# chkconfig: - 21 79
# description: Start and stop Keepalived

# Source function library
#. /etc/rc.d/init.d/functions
. /lib/lsb/init-functions
# Source configuration file (we set KEEPALIVED_OPTIONS there)
. /etc/sysconfig/keepalived

RETVAL=0

prog="keepalived"

start() {
    echo -n $"Starting $prog: "
    daemon keepalived start
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog
}

stop() {
    echo -n $"Stopping $prog: "
    killproc keepalived
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog
}

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

# See how we were called.
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    reload)
        reload
        ;;
    restart)
        stop
        start
        ;;
    condrestart)
        if [ -f /var/lock/subsys/$prog ]; then
            stop
            start
        fi
        ;;
    status)
        status keepalived
        RETVAL=$?
        ;;
    *)
        echo "Usage: $0 {start|stop|reload|restart|condrestart|status}"
        RETVAL=1
esac

exit $RETVAL

6,修改keepalived配置文件

cd /etc/keepalived
cp keepalived.conf keepalived.conf.back
rm keepalived.conf
vim keepalived.conf

#添加内容如下

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.227.100

    }
}

virtual_server  192.168.227.100 80 {
    delay_loop 6
    lb_algo rr
    lb_kind NAT
    persistence_timeout 50
    protocol TCP
     real_server 192.168.227.149 {
            weight 1

     }

}

7,启动keepalived

service keepalived start

8,查看keepalived进程

ps -ef|grep keepalived

9,看是否能Ping通虚拟IP 192.168.227.100
