论坛发帖后，我已经通过论坛发帖了。我无法弄清楚这一点。我正在使用拥有MySQL 5.1的CentOS 6.5，但我需要5.5！我一直在看很多帖子，但是我一直在使用的主要帖子是this one。我已经逐步了解了我所做的事情及其结果。一世 可以告诉我有5.5，但我不能让它开始。

[root@aib-bitest log]# mysql_install_db Installing MySQL system tables... 150417 10:06:12 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release. 150417 10:06:12 [ERROR] Can't find messagefile '/usr/share/mysql/errmsg.sys' 150417 10:06:12 [ERROR] Aborting
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/.
Please check all of the above before submitting a bug report at http://bugs.mysql.com/
