Trouble Shooting

1. 保证3G内存，否则无法成功

2. 更新rpmforge，注意版本对应，之前我遇到的情况是centos的rpmforge是el6版本，需要el7版本，对应名称为rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm。官方网站无法下载，可从csdn下载。

3. 遇到install of mariadb-common-3:10.1.18-3.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.52-1.el7.x86_64， 执行

sudo yum   remove mariadb-libs
