ipvsadm——nat、dr模型

ipvsadm nat模式配置

echo "1" >/proc/sys/net/ipv4/ip_forward

清空配置

ipvsadm -C

添加规则

ipvsadm -A -t 192.168.10.135:80 -s rr

ipvsadm -a -t 192.168.10.135:80 -r 172.16.6.12:80 -m

ipvsadm -a -t 192.168.10.135:80 -r 172.16.6.13:80 -m

查看配置

ipvsadm -L -n

保存配置

ipvsadm -S > /etc/sysconfig/ipvsadm

修改调度算法；

ipvsadm -E -t 192.168.10.135:80 -s sh

从保存的配置文件中重读配置

ipvsadm -C

ipvsadm -R < /etc/sysconfig/ipvsadm

ipvsadm -L -n

删除

ipvsadm -D -t 192.168.10.135:80
