I suddenly noticed that the Firefox browser that ships with CentOS was terribly laggy, and web pages opened far too slowly. So I tried installing Google Chrome, and got an error.
As follows: http://dl.google.com/linux/rpm/stable/x86\_64/repodata/repomd.xml: [Errno 14] curl#7 - “Failed to connect to 2404:6800:4005:800::200e: Network is unreachable” I tried several different places over and over with no luck (the address is blocked), so I simply swapped out the mirror source.
Swap it directly with a command: wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo and then regenerate the cache
yum makecache throws an error: Processing dependencies for libudev.so.0()(64bit), which is required by the package chromium-31.0.1650.63-2.el6.x86_64
What you need to run:
yum install http://mirror.yandex.ru/fedora/russianfedora/russianfedora/nonfree/el/releases/7/Everything/x86\_64/os/opera-developer-24.0.1558.21-3.el7.R.x86\_64.rpm
Problem solved — turned out it was just installing the Opera browser.
