從fedora 19以後，fedora將mysql 替換成了mariadb。這兩個東西雖然同源，但是個人還是喜歡mysql，而且不知道爲什麼，在fedora 20(64bit)下，安裝mariadb我只成功過一次，網上也完全找不到解決辦法。（有誰知道請不吝賜教，謝謝*^_^*)
下面是fedora 20 下面的安裝log
[root@rachel densintian]# yum -y install community-mysql-server #安裝數據庫
已加載插件：langpacks, refresh-packagekit
google-chrome 3/3
正在解決依賴關係
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).
