Firewall> LVS> the FTP 2> glueterfs 2
- lvs DR mode using ftp load tcp port
- ftp mount the duplex copy storage GlusterFS
- Environmental host 2 lvs, 2 sets ftp + GlusterFS
lvs configuration
Specific configuration refer to my blog - "Production LVS load balancing and high availability keepalive practice" https://attacker.club/detail/122.html
Referring to operation mode using the command line on the host lvs
ipvsadm -C # 清理策略
ipvsadm -A -t 10.0.1.15:21 -s rr -p
ipvsadm -a -t 10.0.1.15:21 -r 10.0.1.16:21 -g
ipvsadm -a -t 10.0.1.15:21 -r 10.0.1.17:21 -g
Back-end host ports plus vip loop
vip=10.0.1.15
#把vip绑定在lo上，是为了实现rs直接把结果返回给客户端
ifconfig lo:0 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip lo:0
#以下操作为更改arp内核参数，目的是为了让rs顺利发送mac地址给客户端
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

ftp mount storage
mount -t glusterfs gfsnode-1:rep_vol /home/repo/gfs_data/
# ftp1
mount -t glusterfs gfsnode-2:rep_vol /home/repo/gfs_data/

ps: modify and add new files mounted gfs_data operating, data can be synchronized; not to be confused with the / home / gfs / storage storage directory
