正在解决依赖关系

There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

下载jdkforLinux，使用chmod +x jdk的名字 赋予执行权限。 然后./jdk的名字 。这样便会将jdk安装在当前目录下。 再配置环境变量。文件应该是在/etc/下，名字叫pro啥的，使用命令vi /etc/pro（按tab提示补全文件名），配置环境变量。
