Install IPV6 only install

Please fill in any relevant information that applies to you:

• CentOS Version: CentOS 7 64bit
• Centmin Mod Version Installed: latest stable and beta
• When was last time updated Centmin Mod code base ? : new install
• Persistent Config: No

I have installed Centmin Mod many time with CentOS 6 & 7 server but now I have fresh VPS with IPV6 only and CMM install is failing.

Code:

Download pcre-8.42.tar.gz ...
--2018-07-12 09:02:26--  https://centminmod.com/centminmodparts/pcre/pcre-8.42.tar.gz
failed: Address family for hostname not supported.

This is just one of the examples. I have setup proxy to help connection to ipv4 only places like github but still there are many places in Centmin Mod scripts that have "wget -c4" which is making troubles. I was wondering are those really needed? If they are maybe one place which would define all wget parameters could be better solution since now it is kind of batch replacement to get rid of those.

Has anyone succeeded to install CMM to ipv6 only box?

Thanks, actually I already installed that box with Oneinstack script but I can easily test your modifications tomorrow with similar ipv6 only VPS

 

I've now tried couple time with ipv6 only VPS and it is performing much better with that parameter. Actually only thing that seems to be failing this time is Nginx and specially modules. It seems that for some reason they try still connecting with ipv4

Code:

Installing nginx Modules / Prerequisites...
Download pcre-8.42.tar.gz ...
--2018-07-15 09:23:16--  https://centminmod.com/centminmodparts/pcre/pcre-8.42.tar.gz
failed: Address family for hostname not supported.

Also after installing I found that /usr/local/src/centminmod/centmin.sh has '-4' in WGETOPT which might cause some troubles

 

I finally succeeded installing Centmin Mod to IPV6 only VPS while it was a bit hack but now LEMP is working and thats all I needed. Basicly you still need proxyserver with ipv4 and ipv6. I have installed earlier tinyproxy to port 8888. Before CMM setup you have to modify couple of files. I am not sure that all of these are needed or correct but I will paste those if it helps someone

Code:

# cat .curlrc
proxy = prx:8888

# cat .axelrc
use_protocol= ipv6
http_proxy = prx:8888

# cat .gitconfig
[http]
proxy = http://prx:8888

# cat .wgetrc
use_proxy=yes
http_proxy=http://prx:8888
https_proxy=http://prx:8888

# head -2 /etc/yum.conf
[main]
proxy=http://prx:8888

Also you have to add that 'prx' to your /etc/hosts file with correct ipv6.
After all this you can start normal CMM install procedure and hope for the best

 

oh and one more thing which might be helpful for someone. I had to ctrl+c install script just after it has put all of the stuff to /usr/local/src/centminmod. Then I edited in centmin.sh function called download_cmd to use only wget because otherwise it would fail in OpenSSL setup

Code:

Download openssl-1.1.0h.tar.gz ...
download_cmd https://www.openssl.org/source/openssl-1.1.0h.tar.gz
Proxy request sent, awaiting response... Initializing download: https://www.openssl.org/source/openssl-1.1.0h.tar.gz
HTTP/1.0 500 Unable to connect

but this is prolly due to my limit proxyskills. I will continue post my experiences with ipv6 box while I replace that Oneinstack box with this new CMM box in production.

 

Yep since some places like github.com does not have yet ipv6
