如何使用新的更新日志
如果你只使用一个更新日志,你只须清空日志文件,然后移走旧的更新日志文件到一个备份中,然后启用新的更新日志。
用下列方法可以强制服务器启用新的更新日志:
◆ mysqladmin flush-logs
你一般需要在命令行提供使用的数据库用户:
<p>mysqladmin –u root –p flush-logs</p> Copy after login |
◆ mysqladmin refresh
你一般需要在命令行提供使用的数据库用户:
<p>mysqladmin –u root –p refresh</p> Copy after login |
如果你正在使用MySQL 3.21或更早的版本,你必须使用mysqladmin refresh。
◆ SQL命令
<p>FLUSH LOGS</p> Copy after login |
◆ 重启服务器
上述方法都具有这样的功能:
关闭并且再打开标准和更新记录文件。如果你指定了一个没有扩展名的更新记录文件,新的更新记录文件的扩展数字将相对先前的文件加1。
<p>mysql>FLUSH LOGS;</p> Copy after login |
如何使用新的常规日志
用上面的方法同样可以强制更新常规日志。
要准备备份常规日志,其步骤可能复杂一些:
<p>$ cd mysql-data-directory</p><p>$ mv mysql.log mysql.old</p><p>$ mysqladmin flush-tables</p> Copy after login |
然后做一个备份并删除“mysql.old”。
