LVS负载均衡+三台Route Process服务器

lvs+keepalived一台

mongos服务器分别为172.16.0.103,172.16.0.114,172.16.0.115

1.4.5 Lvs的安装

在lvs+keepalived服务器进行安装：

wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
ln -s /usr/src/kernels/2.6.18-371.9.1.el5-x86_64/ /usr/src/linux
tar zxvf ipvsadm-1.24.tar.gz
cd ipvsadm-1.24
make&& make install
1.4.6 Keepalived的安装
在lvs+keepalived服务器进行安装：
wget http://www.keepalived.org/software/keepalived-1.1.19.tar.gz
tar zxvf keepalived-1.1.19.tar.gz
cd keepalived-1.1.19
./configure --prefix=/usr/local/keepalived
make
make install
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
mkdir /etc/keepalived

1.4.7.1配置keeplived.conf
lvs-master在172.16.0.114上布置
vim /etc/keepalived/keepalived.conf

}
}
lvs-backup在172.16.0.115上布置
vim /etc/keepalived/keepalived.conf



global_defs {

virtual_server 172.16.0.222 60000 {
        delay_loop 6         
        lb_algo rr            
        lb_kind DR

        nb_get_retry 3
        delay_before_retry 3
        connect_port 60000

        real_server 172.16.0.103 60000 {

        nb_get_retry 3
        delay_before_retry 3
        connect_port 60000
}
}
}

三台mongos里增加
vi /etc/init.d/realserver.sh

#!/bin/bash
# description: Config realserver lo and apply noarp

SNS_VIP=172.16.0.222

/etc/rc.d/init.d/functions

case "$1" in
start)
       ifconfig lo:0 $SNS_VIP netmask 255.255.255.255 broadcast $SNS_VIP
       /sbin/route add -host $SNS_VIP dev lo:0
       echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
       echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
       echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
       echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce
       sysctl -p >/dev/null 2>&1
       echo "RealServer Start OK"

       ;;
stop)
       ifconfig lo:0 down
       route del $SNS_VIP >/dev/null 2>&1
       echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore
       echo "0" >/proc/sys/net/ipv4/conf/lo/arp_announce
       echo "0" >/proc/sys/net/ipv4/conf/all/arp_ignore
       echo "0" >/proc/sys/net/ipv4/conf/all/arp_announce
       echo "RealServer Stoped"
       ;;
*)
       echo "Usage: $0 {start|stop}"
       exit 1
esac

exit 0

主备启动keepalived：

/etc/rc.d/init.d/keepalived start

三台mongos启动

/etc/init.d/realserver.sh start

并将keepalived和realserver的启动脚本加入到rc.local自启动中：

echo “/etc/rc.d/init.d/keepalived start” >> /etc/rc.local

echo “/etc/init.d/realserver.sh  start” >> /etc/rc.local
