直到昨天，Ubuntu 10.10 上的 MySQL 5.5 都运行良好，但是今天每当我mysqld_safe以 root 用户身份启动 MySQL 时，它都会显示
Starting mysqld daemon with databases from /var/lib/mysql
然后显示pid ended
我最近没有运行任何更新，但是我使用 MySQL 管理员连接到远程数据库，但 MySQL 管理员是一个月前安装的。
然后我检查了错误文件错误日志并发现了这一点：

答案1
我从超级用户那里交叉复制了这篇文章，它基本上解决了你的问题。
我使用以下指南在 Ubuntu 11.04 上安装 5.5：http://www.ovaistariq.net/490/a-step-by-step-guide-to-upgrading-to-mysql-5-5/
除最后一步（启动 mysql）外，所有步骤均运行正常：
mysqld --skip-grant-tables --user=mysql
向我发送以下消息然后关闭：
[ERROR] Can't find messagefile '/usr/share/errmsg.sys'
经过一些谷歌搜索我发现解决方案是添加以下标志：
--lc-messages-dir="/usr/local/mysql/share/english/"
为了启动它并使其真正发挥作用，我使用了以下命令：
mysqld --skip-grant-tables --user=mysql --lc-messages-dir="/usr/local/mysql/share/english/"
MySQL 5.5 有一些很棒的新功能，可以为我解决分区问题；通过 varchar 进行分区。
祝你好运！
答案2
从您的日志中：
120210 2:33:23 [ERROR] Can't find messagefile '/usr/share/errmsg.sys'
这似乎就是问题所在。检查文件是否存在。
检查文件是否/usr/local/mysql/share/english/errmsg.sys存在然后：
cp /usr/local/mysql/share/english/errmsg.sys /usr/share/errmsg.sys
确保新的 /usr/share/errmsg.sys 文件具有 MySQL 访问的权限，然后尝试重新启动。
从上面的链接来看，这似乎是在用户重新启动机器时发生的。如果你的机器重新启动了，它可能会因为某种原因删除该文件。为什么会这样？不幸的是，我不知道。
答案3
最好不要将文件复制到 fallback 目录。相反，要么在命令行中指定参数，要么将以下内容添加到my.ini/ my.cnf：
[mysqld]
lc_messages_dir = /usr/local/mysql/share
更多细节这里。
答案4
MySQL 不会自动将其错误消息语言设置为英语。我还没有弄清楚为什么会发生这种情况，但解决方案是在命令行上传递--lc-messages=english（以前的）或添加到配置文件中。--languagelanguage=english
错误消息中指定的文件不应该存在：MySQL 不应该在那里查找。如果您将语言环境文件复制到该位置，那么您并没有解决真正的问题；您只是在自找麻烦。
