二 配置LVS
1 Piranha 配置工具设置口令
piranha-passwd
2 启动 Piranha 配置工具服务
service piranha-gui start
3 限制对 Piranha 配置工具的使用
/etc/sysconfig/ha/web/secure/.htaccess
Order deny,allow
Deny from all
Allow from 127.0.0.1
4启用分组转发
/etc/sysctl.conf 中的 net.ipv4.ip_forward = 0 这一行改为：
net.ipv4.ip_forward = 1
5 分配防火墙标记
iptables -t mangle -A PREROUTING -p tcp -d n.n.n.n/32 --dport 80 -j MARK --set-mark 80
三 Piranha 配置工具
1 登陆 打开 http://localhost:3636
2 GLOBAL SETTINGS

3 REDUNDANCY 备份 LVS 路由器节点
Redundant server public IP
备份 LVS 路由器节点的公共真正 IP 地址。
Redundant server private IP

Heartbeat Interval (seconds)
设置为心跳之间的时间
Assume dead after (seconds)
备份 LVS 路由器节点失效转移的时间。
Heartbeat runs on port
主 LVS 节点的心跳通信端口
4 VIRTUAL SERVERS
Name虚拟服务器名称。
Application port

Protocol
UDP 或 TCP
Virtual IP Address
虚拟服务器的浮动 IP 地址。
Virtual IP Network Mask
虚拟服务器子网掩码。
Firewall Mark
防火墙标记
Device

Load monitoring tool
监视各个真正服务器的载量
Scheduling
调度算式
Persistence
连接超时前所允许经过的不活跃期间的秒数
Persistence Network Mask
限制某个特定子网的持续性的子网掩码。
5 REAL SERVER
Name
真正服务器
Address
真正服务器的 IP
Weight
主机权值
6同步配置文件
scp /etc/sysconfig/ha/lvs.cf n.n.n.n:/etc/sysconfig/ha/lvs.cf
scp /etc/sysconfig/iptables n.n.n.n:/etc/sysconfig/
四 LVS部署
1 路由转发
vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
sysctl –p
2 iptables标记
iptables -t mangle -A PREROUTING -p tcp -d 211.144.137.131/32 --dport 80 -j MARK --set-mark 81
iptables -t mangle -A PREROUTING -p tcp -d 211.144.137.232/32 --dport 80 -j MARK --set-mark 82
iptables -t mangle -A PREROUTING -p tcp -d 211.144.137.233/32 --dport 80 -j MARK --set-mark 83
iptables -t mangle -A PREROUTING -p tcp -d 211.144.137.234/32 --dport 80 -j MARK --set-mark 84
iptables -t mangle -A PREROUTING -p tcp -d 211.144.137.235/32 --dport 80 -j MARK --set-mark 85
