云筏科技NAT大盘鸡升级了 免费双倍内存 附上官方开启并获取IPv6地址教程

[root@hSxavP1000044 network-scripts]# sysctl -a | grep ipv6.*disable
sysctl: reading key "net.ipv6.conf.all.stable_secret"
net.ipv6.conf.all.disable_ipv6 = 1
sysctl: net.ipv6.conf.default.disable_ipv6 = 1
reading key "net.ipv6.conf.default.stable_secret"
sysctl: reading key "net.ipv6.conf.eth0.stable_secret"
net.ipv6.conf.eth0.disable_ipv6 = 1
sysctl: reading key "net.ipv6.conf.lo.stable_secret"
net.ipv6.conf.lo.disable_ipv6 = 1

disable=1说明被禁用了，因此需要去修改，配置文件为/etc/sysctl.conf

vi /etc/sysctl.conf
#把ipv6 disable的参数都改为0，然后保存，重载服务后生效
[root@hSxavP1000044 ~]# sysctl -pvm.swappiness = 0
net.ipv4.neigh.default.gc_stale_time = 120
net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.default.rp_filter = 0
net.ipv4.conf.default.arp_announce = 2
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.all.arp_announce = 2
net.ipv4.tcp_max_tw_buckets = 5000
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 1024
net.ipv4.tcp_synack_retries = 2
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0

vi /etc/sysconfig/network-scripts/ifcfg-eth0

在原有配置后面增加输入以下信息：

Networking_IPV6=yes
DHCPV6C=yes
IPV6INIT=yes

然后重启网络：

service network restart

检查是否生效

设置网卡，启用DHCP

nano /etc/network/interfaces

添加一行iface eth0 inet6 dhcp，举例示意：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 172.16.2.X
netmask 255.240.0.0
gateway 172.16.2.1

iface eth0 inet6 dhcp

重启网络，检查是否正常

service networking restart

设置静态IPv6（可选）

IPV6ADDR=【你的IPv6地址】/64
IPV6_DEFAULTGW=【IPv6网关】
