in order to install bazel 2.0 or higher version. i run "yum install bazel2" in centos7.4。

The actual error is class java.net.ConnectException Connection timed out (Connection timed out). Can you verify your network setting? You probably can find some useful solutions at #3 and #581.

Based on the new issue #601 you filed, it seems like this problem is already solved. Feel free to reopen it if you need more help.
