以下的文章主要是对MySQL 5安装的过程中遇到的相关问题的解决，本文主要是以代码的方式来对MySQL 5安装的相关问题的详细解析，如果你对其实际的操作有兴趣的话，你就可以 浏览以下的文章了。
1、[root@localhost bin]# ./MySQLd_safe –skip-grant-tables
出现以下信息：
<ol class="dp-xml"> <li class="alt"><span>Installing MySQL system tables… </span></li> <li><span>090724 12:05:13 [Warning] option ‘max_join_size’: <br>unsigned value 18446744073709551615 adjusted to 4294967295 </span></li> <li class="alt"><span>090724 12:05:13 [Warning] option ‘max_join_size’: <br>unsigned value 18446744073709551615 adjusted to 4294967295 </span></li> <li><span>ERROR: 1062 Duplicate entry ‘localhost-’ for key 1 </span></li> <li class="alt"><span>090724 12:05:13 [ERROR] Aborting </span></li> <li> <span>090724 12:05:13 [Note] /usr/local/</span>MySQL<span>5/libexec/</span>MySQL<span>d: Shutdown complete </span> </li> <li class="alt"><span>Installation of system tables failed! </span></li> <li> <span>Examine the logs in /var/lib/</span>MySQL<span>5 for more information. </span> </li> <li class="alt"> <span>You can try to start the </span>MySQL<span>d daemon with: </span> </li> <li> <span>/usr/local/</span>MySQL<span>5/libexec/</span>MySQL<span>d –skip-grant & </span> </li> <li class="alt"><span>and use the command line tool </span></li> <li> <span>/usr/local/</span>MySQL<span>5/bin/</span>MySQL<span> to connect to the </span>MySQL<span> </span> </li> <li class="alt"><span>database and look at the grant tables: </span></li> <li><span>http://www.knowsky.com/ </span></li> <li class="alt"> <span>shell</span><span class="tag">></span><span> /usr/local/</span>MySQL<span>5/bin/</span>MySQL<span> -u root </span>MySQL<span> </span> </li> <li>MySQL<span class="tag">></span><span> show tables </span> </li> <li class="alt"> <span>Try ‘</span>MySQL<span>d –help’ if you have problems with paths.

2、[root@localhost bin]# /usr/local/MySQL5/libexec/MySQLd –skip-grant &
出现以下信息：
<ol class="dp-xml"> <li class="alt"><span><span>[1] 6633 </span></span></li> <li><span>[root@localhost bin]# 090724 12:05:34 [Warning] option ‘max_join_size’: <br>unsigned value 18446744073709551615 adjusted to 4294967295 </span></li> <li class="alt"><span>090724 12:05:34 [Warning] option ‘max_join_size’: <br>unsigned value 18446744073709551615 adjusted to 4294967295 </span></li> <li> <span>090724 12:05:34 [ERROR] Fatal error: Please read “Security” <br>section of the manual to find out how to run </span>MySQL<span>d as root! </span> </li> <li class="alt"><span>090724 12:05:34 [ERROR] Aborting </span></li> <li> <span>090724 12:05:34 [Note] /usr/local/</span>MySQL<span>5/libexec/</span>MySQL<span>d: Shutdown complete </span> </li> <li class="alt"> <span>[1]+ Exit 1 /usr/local/</span>MySQL<span>5/libexec/</span>MySQL<span>d –skip-grant </span> </li> </ol>
解决办法：在/etc/my.conf中的MySQLd这一节中加入：user=MySQL，以上的相关内容就是对MySQL 5安装遇到的问题的介绍，望你能有所收获。
