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).

[root@localhost ~]#

正确命令是service mysqld start 的，而且如果你不是root权限的话，你sudo启动时是要加上全路径的。

你先which mysqld查看下mysqld服务所在的路径

一般yum安装应该是给你放到系统变量里了的

你先试试吧。。

在Red

hat中yum安装完Mysql后，启动文件的默认路径似乎在/usr/local/bin中，有个mysql的脚本文件，执行./usr/local/bin/mysql

start

就可以启动了，如果配置成服务，需要把这个文件cp到/etc/bin目录，另外还得修改权限。fedora没有玩过，应该差不多，你可以上网搜搜看。
