Add the entry ‘ipv6.disable=1’ to the arguments that are already there.
Save and run

In this guide we’ll create a generic apache config file to ‘automatically’ create virtual hosts for a specific domain in your server
Sometimes you have a development server with one primary domain, and some sub-domains with your projects and/or stuff that still need to be validated
Firstly you will need to disable SELinux or configure the folders appropriately ( not covered in this guide ).

If for any reason you want to disable ipv6 and don’t want to do it with the sysctl directive, if your kernel was compiled with ipv6 support as a module one easy route is to blacklist the ipv6 kernel module.
All you need to do is create/update the ‘/etc/rc.modules.d/blacklist.conf’ file and add the line ‘blacklist ipv6’.
alternatively you can run the following command as root.
' >> /etc/modprobe.d/blacklist.conf
To completely disable IPv6 on your Linux system, side note you shouldn’t but it’s your choice, you can do so simply editing the 99-sysctl.conf file at the location ‘/etc/sysctl.d/99-sysctl.conf’
Copy and paste the following 3 lines at the bottom of the file.
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
After editing the file you need to then reboot the machine or run the following command as root
To verify that you have ipv6 disabled you can run
