Otu esi ahazi netwọk IPv6 na CentOS/RHEL 8

Emepụtara adreesị IPv6 na atụmanya nke njedebe nke adreesị IPv4. Ezubere ya iji dozie ike ọgwụgwụ nke adreesị IPv4 site na iji oghere mgbasa ozi netwọk sara mbara karị. Adreesị IPv6 bụ nọmba 128-bit nwere otu 8 kewapụrụ colon nke ọ bụla mejupụtara ọnụọgụ hexadecimal anọ.

Egosiri ihe atụ nke adreesị IPv6 n'okpuru:

2001:1:1:1443:0:0:0:400

A na-enyekarị IPv6 site na ndabara na CentOS/RHEL 8. Iji lelee ma ọ bụrụ na agbanyere IPv6 na sistemụ gị, mee iwu:

$ sudo sysctl -a | grep ipv6.*disable

Uru 0 na-egosi na IPv6 na-arụ ọrụ na ọnụ gị. Uru nke 1 na-egosi na agbanyụrụ IPv6. Ya mere, site na mmepụta n'elu, IPv6 na-enyere.

Ụzọ ọzọ a na-enyocha ma ọ bụrụ na enyere IPv6 aka bụ site na ịlele interface netwọk gị na /etc/network-scripts/ directory. N'ọnọdụ anyị, nke a ga-abụ faịlụ /etc/sysconfig/network-scripts/ifcfg-enps03.

Yabụ ka anyị mebie iwu dị n'okpuru wee lelee ma enyere IPv6 aka.

$ cat /etc/sysconfig/network-scripts/ifcfg-enps03

Lezienụ anya maka nhọrọ IPV6 ndị a dị ka egosiri:

  • IPV6INIT=ee – Nke a na-ebute ihu ihu maka adreesị IPv6.
  • IPV6_AUTOCONF=ee – Nke a na-enyere IPv6 aka nhazi nhazi maka interface.
  • IPV6_DEFROUTE=ee – Nke a na-egosi na e kenyere ụzọ IPv6 ndabara na interface ahụ.
  • IPV6_FAILURE_FATAL= mba – na-egosi na sistemu a agaghị ada ọbụlagodi mgbe IPv6 dara.

Nsonaazụ dị n'elu na-akwado na agbanyere adreesị IPv6. Na ọnụ ọnụ, ị nwere ike ịlele adreesị IPv6 nke ihu gị site na iji iwu IP dị n'okpuru.

$ ip a
OR
$ ip -6 addr

Lezienụ anya maka prefix inet6 dị ka egosiri n'okpuru.

Iji gbanyụọ IPv6 nwa oge, gbanye iwu:

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ ip -6 addr

Iji mee ka IPv6 nwee ike, gbanye iwu:

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0

Mgbe ahụ malitegharịa NetworkManager maka mgbanwe itinye.

$ sudo systemctl restart NetworkManager

Iji gbanyụọ IPv6 kpamkpam, dezie faịlụ GRUB /etc/default/grub. N'ahịrị, GRUB_CMDLINE_LINUX, tinye arụmụka ipv6.disable=1 na njedebe nke ahịrị dịka egosiri.

Ka itinye mgbanwe ndị a, malitegharịa sistemụ gị.

Dịka IPv4, nhazi akwụkwọ ntuziaka nke IPv6 ga-ekwe omume site na iji ngwaọrụ nmcli. Otú ọ dị, a naghị atụ aro nke a n'ihi na nhazi akwụkwọ ntuziaka nke IPv6 na-enwekarị mmejọ ma dị oke ike.

Ọzọkwa, ọ bụ ezigbo ọrụ idobe nke adreesị IPv6 kenyere na sistemụ kedụ. Ohere bụ na ị nwere ike mebie nhazi gị.
