mysql 启动

fedora 系统装上以后

1,自带的那个mysql能不能用？

2,如果能用，怎么启动？

 

3,

rpm -qa|grep mysql 以后出现

mysql,php信息，以及find:WARNING:Hard link count is wrong for proc/1:this may be a bug in your filesysWarning:bad syntax,perhaps a bogus'-'?See /usr/share/doc/procps-3.2.7/FAQ
tem driver.Automatically turning on find's -noleaf option.Earlier results may have failed to include directories that should have been searched"
4,

在那个my.cnf里有：
user=mysql
old_password=1

，这是不是就是用户名和密码？
