      centos配置ipv6服务器具体操作步骤:

      第一步:查看CentOS版本号:

      [root@host etc]# cat /etc/centos-release
      CentOS release 6.8 (Final)
      是6.6及以上版本

      第二步:设置centos系统服务器支持IPv6

      vi /etc/sysctl.conf
       
      配置上以下3条属性
      net.ipv6.conf.all.disable_ipv6 = 0
      net.ipv6.conf.default.disable_ipv6 = 0
      net.ipv6.conf.lo.disable_ipv6 = 0
       
      保存

      第三步:运行 sysctl -p

      [root@host etc]# sysctl -p
      net.ipv4.ip_forward = 0
      net.ipv4.conf.default.rp_filter = 1
      net.ipv4.conf.default.accept_source_route = 0
      kernel.sysrq = 0
      kernel.core_uses_pid = 1
      net.ipv4.tcp_syncookies = 1
      kernel.msgmnb = 65536
      kernel.msgmax = 65536
      kernel.shmmax = 68719476736
      kernel.shmall = 4294967296
      net.core.default_qdisc = fq
      net.ipv4.tcp_congestion_control = bbr
      net.ipv4.neigh.default.base_reachable_time_ms = 600000
      net.ipv4.neigh.default.mcast_solicit = 20
      net.ipv4.neigh.default.retrans_time_ms = 250
      net.ipv6.conf.all.disable_ipv6 = 0
      net.ipv6.conf.default.disable_ipv6 = 0
      net.ipv6.conf.lo.disable_ipv6 = 0

      第四步:查看服务器是否已支持ipv6

      [root@host etc]# ifconfig | grep inet
      [root@host etc]# netstat -tuln
      [root@host etc]# lsmod
       

      可以向服务器提供商申请一个IPv6地址


      注:申请网站用google浏览器打开为佳,本人之前用别的浏览器打开注册,会因为排版格式注册失败

      第五步:测试是否可以访问IPv6网站

      [root@host etc]# ping6 -c 5 ipv6.google.com
      PING ipv6.google.com(lax28s15-in-x0e.1e100.net) 56 data bytes
      64 bytes from lax28s15-in-x0e.1e100.net: icmp_seq=1 ttl=57 time=1.73 ms
      64 bytes from lax28s15-in-x0e.1e100.net: icmp_seq=2 ttl=57 time=1.44 ms
      64 bytes from lax28s15-in-x0e.1e100.net: icmp_seq=3 ttl=57 time=0.913 ms
      64 bytes from lax28s15-in-x0e.1e100.net: icmp_seq=4 ttl=57 time=1.25 ms
      64 bytes from lax28s15-in-x0e.1e100.net: icmp_seq=5 ttl=57 time=1.09 ms
       
      --- ipv6.google.com ping statistics ---
      5 packets transmitted, 5 received, 0% packet loss, time 4040ms
      rtt min/avg/max/mdev = 0.913/1.288/1.732/0.285 ms
      ------------------------------------------------------------------------

      最后一步:

      如果你使用的是阿里云服务器。

      阿里云服务器上配置ipv6时,tunnelbroker网站上的Example Configurations 选项选择Linux-net-tools,使用下面指令配置

      成功

      ifconfig sit0 up
      ifconfig sit0 inet6 tunnel ::74.82.46.6
      ifconfig sit1 up
      ifconfig sit1 inet6 add 2001:470:23:60f::2/64
      route -A inet6 add ::/0 dev sit1

      [root@******** sysconfig]# ping6 -c 5  ipv6.google.cn
      PING ipv6.google.cn(tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e)) 56 data bytes
      64 bytes from tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e): icmp_seq=1 ttl=57 time=401 ms
      64 bytes from tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e): icmp_seq=2 ttl=57 time=383 ms
      64 bytes from tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e): icmp_seq=3 ttl=57 time=403 ms
      64 bytes from tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e): icmp_seq=4 ttl=57 time=385 ms
      64 bytes from tsa03s06-in-x0e.1e100.net (2404:6800:4012:1::200e): icmp_seq=5 ttl=57 time=392 ms
       
      --- ipv6.google.cn ping statistics ---
      5 packets transmitted, 5 received, 0% packet loss, time 496ms
      rtt min/avg/max/mdev = 383.001/392.847/402.759/8.032 ms
