Post the contents of /etc/sysconfig/network-scripts/ifcfg-eth0

Although I don't think this is the cause of my problem.I still update to CentOS 6.9 by yum update.But it can't resolove my problem.
My "ifcfg-eth0" content is :

Code: Select all

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=dhcp
IPV6INIT=yes
DHCPV6C=yes
DHCPV6C_OPTIONS="-S"

Have you asked your ISP how you should configure your IPv6 address? Not all ISPs support DHCPv6.

You're getting a response from the httpd (http error 502) so something is listening there - on port 80. You can use ss -antlp (as root, or sudo) to see what's listening there.
