利用LVS+Keepalived 实现高性能高可用负载均衡服务器(4)
connect_port 80
}
}
real_server 61.164.122.10 80 {
weight 3
TCP_CHECK {
connect_timeout 10
nb_get_retry 3
delay_before_retry 3
connect_port 80
}
}
}
2. BACKUP服务器同上配置，先安装lvs再按装keepalived,仍后配置/etc/keepalived/keepalived.conf，只需将红色标示的部分改一下即可.
3. vi /etc/rc.local
#/usr/local/sbin/lvs-dr.sh 将lvs-dr.sh这个脚本注释掉。步
#/usr/local/sbin/lvs-dr.sh stop 停止lvs-dr脚本
#/etc/init.d/keepalived start 启动keepalived 服务，keepalived就能利用keepalived.conf 配
置文件，实现负载均衡和高可用.
4. 查看lvs服务是否正常
#watch ipvsadm –ln

-> 61.164.122.9:80 Route 3 0 0#tail –f /var/log/message 监听日志，查看状态，测试LVS负载均衡及高可用性是否有效。
5．停Master服务器的keepalived服务，查看BAKCUP服务器是否能正常接管服务。
