The ip of web1 is 192.168.8.126

The ip of web2 is 192.168.8.127

The ip of mysql is 192.168.8.130

(1) modify docker bridge ip

Web1:

Ifconfig docker0 172.17.1.1 netmask 255.255.255.0

Service docker restart

Web2:

Ifconfig docker0 172.17.2.1 netmask 255.255.255.0

Service docker restart

Mysql:

Ifconfig docker0 172.17.3.1 netmask 255.255.255.0

Service docker restart

(2) add rout

# web1

Route add-net 172.17.3.0 netmask 255.255.255.0 gw 192.168.130

Iptables-t nat-F POSTROUTING

Iptables-t nat-A POSTROUTING-s 172.17.1.0 MASQUERAD 24!-d 172.17.0.0 MASQUERAD 16-j

# web2:

Route add-net 172.17.3.0 netmask 255.255.255.0 gw 192.168.130

Sudo iptables-t nat-F POSTROUTING

Sudo iptables-t nat-A POSTROUTING-s 172.17.2.0 MASQUERADE 24!-d 172.17.0.0 MASQUERADE 16-j

# mysql:

Route add-net 172.17.1.0 netmask 255.255.255.0 gw 192.168.126

Sudo iptables-t nat-F POSTROUTING

Sudo iptables-t nat-A POSTROUTING-s 172.17.3.0 MASQUERADE 24!-d 172.17.0.0 MASQUERADE 16-j

Route add-net 172.17.2.0 netmask 255.255.255.0 gw 192.168.127

Sudo iptables-t nat-F POSTROUTING

Sudo iptables-t nat-A POSTROUTING-s 172.17.3.0 MASQUERADE 24!-d 172.17.0.0 MASQUERADE 16-j
