(133) Yammer : View Conversation
https://unix.stackexchange.com/questions/138899/centos-install-using-yum-apache-2-4


cat /etc/redhat-release
CentOS release 6.9 (Final)
sudo /opt/aaa/bin/httpd -V
Server version: Apache/2.4.25 (Unix) openssl-1.0.2 nghttp2

git clone https://github.com/n13l/http2-pkcs11
cd http2-pkcs11
./scripts/checkout.sh
./scripts/build-linux.sh

This is git repository with script which downloads all dependecies for apache2 2.4.x openssl-1.0.2 and nghttp2 with http2 support. build script then build everything for redhat and install results to /opt/aaa because otherwise there are collisions with system openssl etc.

HTTPoxy - CGI "HTTP_PROXY" variable name clash - Red Hat Customer Portal
test.cgi:
#!/bin/sh
echo "Content-Type:text/plain"
echo ""
echo "HTTP_PROXY='$HTTP_PROXY'"

Then call the CGI script with a “Proxy:” request header:

curl -H ‘Proxy: AFFECTED’ http://my-server-name/cgi-bin/test.cgi


If you see the following output, your server is unaffected:
HTTP_PROXY="


If instead you see the following, or any other output, your server may be affected and you should apply one of the mitigations below:
HTTP_PROXY='AFFECTED'

For Servergraph, add
"RequestHeader unset Proxy early"
at around line 58 httpd.conf

RHEL 7, switch to graphical session? - Red Hat Customer Portal
@Server with GUI is syntax for specifying a group, and no group with that name exists. @^Server with GUI is the proper syntax for an environment, and should work fine. @^graphical-server-environment should also work fine.

How do I disable the creation of the rescue boot image on CentOS? - Unix & Linux Stack Exchange
The rescue image is automatically generated by dracut after a new kernel is installed, and this can be prevented by creating a file under /etc/dracut.conf.d/, containing:

dracut_rescue_image="no"
(The file must have a '.conf' extension)
