LVS DR模式 分發器的設置
配置ens33網卡
[root@lynn-04 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens33 DEVICE=ens33 ONBOOT=yes IPADDR=192.168.130.116 NETMASK=255.255.255.0 GATEWAY=192.168.130.2 DNS1=119.29.29.29
啟動nginx 這裏nginx是自定義安裝的啟動文件時自己設置的
[root@lynn-04 ~]# /etc/init.d/nginx start [root@lynn-04 ~]# ps aux |grep nginx root 912 0.0 0.1 45988 1240 ? Ss 08:06 0:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf nobody 913 0.0 0.4 48476 4388 ? S 08:06 0:00 nginx: worker process nobody 915 0.0 0.4 48476 4392 ?

寫/usr/local/sbin/lvs_dr.sh腳本
[root@lynn-04 ~]# vim /usr/local/sbin/lvs_dr.sh #! /bin/bash echo 1 > /proc/sys/net/ipv4/ip_forward ipv=/usr/sbin/ipvsadm vip=192.168.130.100 rs1=192.168.130.118 rs2=192.168.130.128 #註意這裏的網卡名字 ifdown ens33 ifup ens33 ifconfig ens33:2 $vip broadcast $vip netmask 255.255.255.255 up route add -host $vip dev ens33:2 $ipv -C $ipv -A -t $vip:80 -s rr $ipv -a -t $vip:80 -r $rs1:80 -g -w 1 $ipv -a -t $vip:80 -r $rs2:80 -g -w 1
執行/usr/local/sbin/lvs_dr.sh腳本
[root@lynn-04 ~]# sh /usr/local/sbin/lvs_dr.sh
成功斷開設備 ‘ens33‘。
