   150417 10:06:12 [Note]
   Installation of system tables failed!  Examine the logs in    /var/lib/mysql for more information.
   You can try to start the mysqld daemon with:

   shell>     /usr/libexec/mysqld --skip-grant &
   and use the command line tool /usr/bin/mysql    to connect to the mysql database and look at the grant tables:

   shell>     /usr/bin/mysql -u root mysql
   mysql>     show tables
   Try 'mysqld --help' if you have problems with paths.  Using --log    gives you a log in /var/lib/mysql that may be helpful.
   Please consult the MySQL manual section    'Problems running mysql_install_db', and the manual section that    describes problems on your OS.  Another information source are the    MySQL email archives available at http://lists.mysql.com/.

感谢您重新格式化。请尝试在控制台中运行/usr/libexec/mysqld，而不是通过service命令，然后查看它打印的内容。这里经常有有用的信息，你是如何从5.1升级到5.5的？RPM还是？您是否遵循了上的升级说明。如果您从mysql RPM repo升级，那么请检查他们称之为mysql社区服务器的包名。当你尝试启动它时，你能发布什么登录/var/log/messages吗？上面的东西看起来像是它的控制台输出还是什么？
