Nginx IPv6 Install

WPSparky · Mar 21, 2022

Please fill in any relevant information that applies to you:
CentOS Version: i.e. CentOS 6 32bit or 64bit / CentOS 7 64bit ?

Centmin Mod Version Installed: i.e. 123.08stable or 123.09beta01

Nginx Version Installed: i.e. 1.15.3

PHP Version Installed: i.e. 5.6.37, 7.0.31, 7.1.21, 7.2.9

MariaDB MySQL Version Installed: i.e. 10.0.x or 10.1.xx or 10.2.xx

When was last time updated Centmin Mod code base ? : i.e. run centmin.sh menu option 23 submenu option 2 or cmupdate command
Persistent Config: Do you have any persistent config file options set in /etc/centminmod/custom_config.inc ? You can check via this command:
Code (Text):
cat /etc/centminmod/custom_config.inc
Post output in CODE tags.
With a fresh install, What do I need to enable in the persistent config file? IPv6only 'y' ?

eva2000 · Mar 21, 2022

Nothing is needed to change on Centmin Mod if you have a IPv4 + IPv6 system by default. The persistent config file variable if set to DISABLE_IPVSIX='y' option is mainly there to disable IPv6 by default if IPv6 system is supported. If you want IPv6 supported, you don't have to set any persistent config file variables. Though Nginx IPv6 listen directives aren't setup by default for new Nginx vhosts, you have to add them yourself - see official Centmin Mod FAQ item 34 FAQ - CentminMod.com LEMP Nginx web stack for CentOS

If your problem is a server with ipv6 address only, I am actually looking into this myself as well as centminmod.com (for example) is not accessible from ipv6 only server. If you have ipv4 connectivity + ipv6, then my post is irrelevant.

So for ipv6 only server (no ipv4 address available) a NAT64 or similar service is needed. If it helps, these are the ones I am looking into currently.

Correction, only this part results in "failed: Network is unreachable" error.
Code:
ALTPCRELINK="${LOCALCENTMINMOD_MIRROR}/centminmodparts/pcre/${ALTPCRELINKFILE}"

I did not open own thread yet, since I thought there is something wrong on my end.

tininho · Mar 28, 2022

Code:
FORCE_IPVFOUR='n'
NGINX_IPV='y'
This is on my custom_config, but I get stuck the same way as user atomi explains here: IPV6 only install

So I am trying the proxy/NAT64 way with tayga/clatd/jool, but it's a work in progress, as I have to learn this stuff at the same time.

Could it be fixed with adding ipv_forceopt='6' here (on Centminmod installer*.php)?
Code:
if [ -f /etc/centminmod/custom_config.inc ]; then
  source /etc/centminmod/custom_config.inc
fi
if [[ "$FORCE_IPVFOUR" != [yY] ]]; then
  ipv_forceopt=""
else
  ipv_forceopt='4'
fi

eva2000 · Mar 29, 2022

Ah yes that would probably be the reason IPv6 only Centmin Mod isn't working for downloads. I force IPv4 where possible to reduce IPv6 connectivity issues/instability with FORCE_IPVFOUR='y' but seems FORCE_IPVFOUR='n' isn't working for the initial install unless you set it up in persistent config file /etc/centminmod/custom_config.inc BEFORE initial install - are you doing that?

tininho · Mar 30, 2022

I've set FORCE_IPVFOUR='n' on custom_config prior to install (fresh Centos7 ipv6 only vps), and I've actually set it on installer74.sh too (changed the hard coded from 'y' -> 'n'), just to be sure.

Somehow wget -c4 still remains:

From Centminmod logs:

I can install other stacks on the same server just fine, and get a working and reachable web domain (from ipv4 desktop). Would love to have Centminmod stack, so I will continue looking into this.

Just updated 123.09beta01 to see if I can fix those hardcoded ones https://community.centminmod.com/th...6-routine-update-fixes-in-123-09beta01.22580/. Let me know if I missed any

Overlooked one change I missed. So updated Centmin Mod 123.09beta01 again. Should cover it I believe.

Today Centminmod seemed to complete the installation pretty much completely. Also option 22 wordpress site install works, but I have to check you posts on ipv6 and nginx to get the conf correctly. Great work as always!
