卸载MySQL5.0_MySQL
昨天在Navicat for mysql中导入一个脚本,运行,出现乱码。
考虑到可能是版本问题,就想卸载了重新安装MYSQL,这一卸载倒是出了问题,导致安装的时候安装不上。
后来无意发现是卸载的时候没有卸载完全导致,下面给出完整的卸载MySQL 5.1的卸载方法:
1、控制面板里的增加删除程序内进行删除
2、删除MySQL文件夹下的my.ini文件,如果备份好,可以直接将文件夹全部删除
3、开始->运行-> regedit 看看注册表里这几个地方删除没有
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL 目录删除
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL 目录删除
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL 目录删除(我卸载的时候没有找到,略过后仍达到完全卸载的目的。)
4、这一条是很关键的
C:\Documents and Settings\All Users\Application Data\MySQL(win7 中即使有管理员权限也打不开C:\Documents and Settings\All Users\,这个路径相当于C:\user\All Users\)
如果这里还有MySQL的文件,必须要删除。(我的文件夹没有东西)
注意:Application Data这个文件夹是隐藏的,需要打开个文件夹选择菜单栏 工具→文件夹选项→查看→隐藏文件和文件夹 一项选上 显示所有文件和文件夹 确定
4步完成后,重启 OK!再次安装吧。
==================================
首先, 查看mysql数据库安装时候选择的编码格式 :
<code class="hljs asciidoc">mysql> status; -------------- D:\Program Files\MySQL\MySQL Server 5.0\bin\mysql.exe Ver 14.12 Distrib 5.0.96, for Win32 (ia32) Connection id: 87 Current database: Current user: root@localhost SSL: Not in use Using delimiter: ; Server version: 5.0.96-community-nt MySQL Community Edition (GPL) Protocol version: 10 Connection: localhost via TCP/IP Server characterset: utf8 Db characterset: utf8 Client characterset: utf8 Conn. characterset: utf8 TCP port: 3306 Uptime: 4 hours 59 min 9 sec Threads: 5 Questions: 8288 Slow queries: 0 Opens: 2234 Flush tables: 1 Open tables: 5 Queries per second avg: 0.462 --------------</code>
