CentOS 7, ipv6 and yum

If you need to disable IPv6 on CentOS 7, you can follow this method that you can find on a lot of sites using google:


vi /etc/sysctl.d/disable-ipv6.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Then issue sysctl -p

However you still try to contact IPv6 addresses, so the solution consists in adding this line

ip_resolve=4

to

/etc/yum.conf
