生命壹号,选拔相应版本MSI版下载

【声明】 

一、MySQL的下载:

深信大家利用MySQL都有过重装的经历,借使重装MySQL基本都以在最终一步通可是,除非重装操作系统,究其原因便是系统里的注册表没有删除干净。上面是自小编总计的一点经历,都是血的教训:

安装的时候,有时候会并发could not start the service mysql error:0
提醒错误。

小说来源:http://www.cnblogs.com/smyhvae/p/4026782.html

上海教室中,咱们选用红框部分的社区版本举行下载,MySQL接济广大平台:

解决步骤:

 

ca88亚洲城网站 3

1、开始-MySQL-MySQL Server 5.1-MySQL Server Instance Config
Wizard-Next-Remove Instance。

【正文】

自家的操作系统是63人的,选拔相应版本MSI版下载,弹出login界面,
选取no thanks,just start my download直接下载即可:

② 、进入增加删除程序,找到MySQL选拔卸载,选取remove。

【开发环境】

 

叁 、进入注册表。

物理机版本:Win 7智速版(61个人)

二、MySQL的安装:

3.1、查看HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\瑟维斯s
下的键值,假设有有关mysql键值(mysql、mysqladmin)则删掉,即可;
3.2、查看HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\下有mysql目录就要删除。

MySQL版本:5.5.40MSI版(64位)

软件下载达成后,就起来设置吧。

3.3、查看HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\下有mysql目录就要删除。

一 、数据库类型:

ca88亚洲城网站 4

3.4、查看HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\瑟维斯s下有没有关于Mysql键值,有删除,即可。

(1)关周详据库

上航海用教室中,提议选取第壹项的Custom,自定义安装。弹出如下界面:

3.5、查看HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services下有没有关于Mysql键值,有删除,即可。

(2)面向对象数据库

ca88亚洲城网站 5
 

3.6、查看HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services下有没有关于Mysql键值,有删除,即可。

(3)XML数据库

三、MySQL的配置:

4、删除C:\Documents and Settings\All Users\Application
Data目录下的MySQL目录。

今天的主流是关系型数据库。

ca88亚洲城网站 6

伍 、进入MySql安装目录,删除目录。

 

 

六 、在进入注册表搜索关键字MYSQL 看看还有没有跟MYSQL有关系的;

② 、数据库产品:

ca88亚洲城网站 7

不要求重启电脑,间接重新安装即可。

  • 特大型数据库有:Oracle、Sybase、DB贰 、SQL server
  • 微型数据库有:MySQL、Access等

ca88亚洲城网站 8

专注:在重新安装MySql在此以前,最好是把数据库备份一下。

地点列举的数据库都以关系型数据库,只是Oracle中有一小部分是面向对象的。MySQL具有开源、免费等特点,适合中小型公司的支出。

 ca88亚洲城网站 9

特意提示:注意日志文件是相当首要的,对于mysql来说,假诺产生哪些难以化解的题材,先查data下的.err文件才是王道。

 

ca88亚洲城网站 10

① 、在“运维”里键入regedit进入注册表。

三 、关系型数据库的基本概念:

 ca88亚洲城网站 11

2、HEKY_LOCAL_MACHINE\SOFTWARE\MYSQL目录删除

关系型数据库是由七个表(table)和表之间的关联关系构成的多少的会见,表是一个由若干行、若干列组成的二维的涉嫌结构。

ca88亚洲城网站 12

3、HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL
目录删除

ca88亚洲城网站 13

上海教室的表明:今后在Java开发中,要对这几个服务器实行访问,就要涉及到通讯的磋商,那里运用TCP/IP协议,此时就事关到了端口,MySQL暗中认可的端口号为3306,使用暗中认可的即可。继续下一步:

4、HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL
目录删除

上航海用体育地方中,表的列称为字段(field),表的行成为记录(record)。字段是表的布局,记录是表的多寡。

ca88亚洲城网站 14

5、HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL目录删除注册表中的ControlSet001,ControlSet002,不自然是001和002,恐怕是ControlSet00⑤ 、006等等,删除的时候,都剔除就足以

四、MySQL的下载:

 

6、删除C:\Documents and Settings\All Users\Application
Data\下的MySQL文件夹

官网下载地址:http://www.mysql.com/

上航海用体育场地中,是选用数据库的编码。第2种是拉丁文,只辅助英文,不支持粤语;第二种貌似是和葡萄牙语有关的。那里大家选取第三种:自定义。然后将编码格局设置为:utf-8。下一步:

⑦ 、最终卸载MySQL。

ca88亚洲城网站 15

ca88亚洲城网站 16

⑧ 、删除MySQL安装路径下的文件夹。

ca88亚洲城网站 17

上海体育场地中,我们勾选“路径添加到环境变量”,然后继续:

⑨ 、最好重启下电脑。

上海教室中,能够见见MySQL有多个本子:集团版、集群版、社区版。社区版就是我们所急需的本子,GPL是一种开源的说道。点击上图中红框中的链接,进入此外三个界面:

ca88亚洲城网站 18

OK!了(脚本之家笔者提醒:近期以上办法在MySQL版本是MySQL
5.0的情事下得以重装成功,其余版本要求大家表明了)

ca88亚洲城网站 19

上海教室中,是给root用户安装密码。那里,作者将密码设置为smyh。别的,勾选“允许用户远程(网路)访问”,不然只可以在地面访问,继续:

(当然Windows7下卸载了MySQL后仿佛从未了上述的多少个登记表项,所以在Windows7下得以健康的重装)

上海体育场所中,大家挑选红框部分的社区版本举行下载,弹出如下界面:

五、MySQL的安装:

点击它,起初运维:

双击安装包时,出现了那么些错误:

ca88亚洲城网站 29

ca88亚洲城网站 30

打开”总计机管理“能够看出MySQL的劳动已运行:

可以吗,没悟出官网下载的软件都能出难点。算了,作者要么下老版本的吧。

ca88亚洲城网站 31

ca88亚洲城网站 32

并且在经过中也足以看到:

点击上航海用教室中红框部分,弹出如下界面:

ca88亚洲城网站 33

ca88亚洲城网站 34

 

上海教室中,点击红框部分,弹出如下界面:

四、MySQL的卸载:

ca88亚洲城网站 35

① 、到控制面板里面先把mysql软件删除;

不要登记,直接下载吧。。。

② 、删除mysql的安装目录(如若在别的盘还有设置目录也要刨除,空目录也要删减);

 

叁 、删除注册表中的以下文件:(按”Win+奥迪Q7″键,输入regedit,进入注册表):

五、MySQL的安装:

  • HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Applications/MySQL
  • HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Applications/MySQL
  • HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Applications/MySQL

软件下载完毕后,就开首设置吧。

部分话全部刨除(技巧:用F3循环查找“mysql”);

ca88亚洲城网站 36

④ 、如若是windows 7
系统,还要求找到C:\ProgramData\MYSQL将其删除;倘若是XP系统,删除找到C:\Documents
and Settings\All Users\Application Data\MYSQL

ca88亚洲城网站 37

成功后即可重新安装,不须求重启系统。

# MySQL Server Instance Configuration File
# ----------------------------------------------------------------------
# Generated by the MySQL Server Instance Configuration Wizard
#
#
# Installation Instructions
# ----------------------------------------------------------------------
#
# On Linux you can copy this file to /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options
# (@localstatedir@ for this installation) or to
# ~/.my.cnf to set user-specific options.
#
# On Windows you should keep this file in the installation directory 
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
# make sure the server reads the config file use the startup option 
# "--defaults-file". 
#
# To run run the server from the command line, execute this in a 
# command line shell, e.g.
# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# To install the server as a Windows service manually, execute this in a 
# command line shell, e.g.
# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# And then execute this in a command line shell to start the server, e.g.
# net start MySQLXY
#
#
# Guildlines for editing this file
# ----------------------------------------------------------------------
#
# In this file, you can use all long options that the program supports.
# If you want to know the options a program supports, start the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.
#
#
# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]
port=3306
[mysql]
default-character-set=utf8
# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.
#
[mysqld]
# The TCP/IP Port the MySQL Server will listen on
port=3306
#Path to installation directory. All paths are usually resolved relative to this.
basedir="D:/MySQL/MySQL Server 5.5/"
#Path to the database root
datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/"
# The default character set that will be used when a new schema or table is
# created and no character set is defined
character-set-server=utf8
# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB
# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
# The maximum amount of concurrent sessions the MySQL server will
# allow. One of these connections will be reserved for a user with
# SUPER privileges to allow the administrator to login even if the
# connection limit has been reached.
max_connections=100
# Query cache is used to cache SELECT results and later return them
# without actual executing the same query once again. Having the query
# cache enabled may result in significant speed improvements, if your
# have a lot of identical queries and rarely changing tables. See the
# "Qcache_lowmem_prunes" status variable to check if the current value
# is high enough for your load.
# Note: In case your tables change very often or if your queries are
# textually different every time, the query cache may result in a
# slowdown instead of a performance improvement.
query_cache_size=0
# The number of open tables for all threads. Increasing this value
# increases the number of file descriptors that mysqld requires.
# Therefore you have to make sure to set the amount of open files
# allowed to at least 4096 in the variable "open-files-limit" in
# section [mysqld_safe]
table_cache=256
# Maximum size for internal (in-memory) temporary tables. If a table
# grows larger than this value, it is automatically converted to disk
# based table This limitation is for a single table. There can be many
# of them.
tmp_table_size=34M
# How many threads we should keep in a cache for reuse. When a client
# disconnects, the client's threads are put in the cache if there aren't
# more than thread_cache_size threads from before.  This greatly reduces
# the amount of thread creations needed if you have a lot of new
# connections. (Normally this doesn't give a notable performance
# improvement if you have a good thread implementation.)
thread_cache_size=8
#*** MyISAM Specific options
# The maximum size of the temporary file MySQL is allowed to use while
# recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.
# If the file-size would be bigger than this, the index will be created
# through the key cache (which is slower).
myisam_max_sort_file_size=100G
# If the temporary file used for fast index creation would be bigger
# than using the key cache by the amount specified here, then prefer the
# key cache method.  This is mainly used to force long character keys in
# large tables to use the slower key cache method to create the index.
myisam_sort_buffer_size=68M
# Size of the Key Buffer, used to cache index blocks for MyISAM tables.
# Do not set it larger than 30% of your available memory, as some memory
# is also required by the OS to cache rows. Even if you're not using
# MyISAM tables, you should still set it to 8-64M as it will also be
# used for internal temporary disk tables.
key_buffer_size=55M
# Size of the buffer used for doing full table scans of MyISAM tables.
# Allocated per thread, if a full scan is needed.
read_buffer_size=64K
read_rnd_buffer_size=256K
# This buffer is allocated when MySQL needs to rebuild the index in
# REPAIR, OPTIMZE, ALTER table statements as well as in LOAD DATA INFILE
# into an empty table. It is allocated per thread so be careful with
# large settings.
sort_buffer_size=256K
#*** INNODB Specific options ***
# Use this option if you have a MySQL server with InnoDB support enabled
# but you do not plan to use it. This will save memory and disk space
# and speed up some things.
#skip-innodb
# Additional memory pool that is used by InnoDB to store metadata
# information.  If InnoDB requires more memory for this purpose it will
# start to allocate it from the OS.  As this is fast enough on most
# recent operating systems, you normally do not need to change this
# value. SHOW INNODB STATUS will display the current amount used.
innodb_additional_mem_pool_size=3M
# If set to 1, InnoDB will flush (fsync) the transaction logs to the
# disk at each commit, which offers full ACID behavior. If you are
# willing to compromise this safety, and you are running small
# transactions, you may set this to 0 or 2 to reduce disk I/O to the
# logs. Value 0 means that the log is only written to the log file and
# the log file flushed to disk approximately once per second. Value 2
# means the log is written to the log file at each commit, but the log
# file is only flushed to disk approximately once per second.
innodb_flush_log_at_trx_commit=1
# The size of the buffer InnoDB uses for buffering log data. As soon as
# it is full, InnoDB will have to flush it to disk. As it is flushed
# once per second anyway, it does not make sense to have it very large
# (even with long transactions).
innodb_log_buffer_size=2M
# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
# row data. The bigger you set this the less disk I/O is needed to
# access data in tables. On a dedicated database server you may set this
# parameter up to 80% of the machine physical memory size. Do not set it
# too large, though, because competition of the physical memory may
# cause paging in the operating system.  Note that on 32bit systems you
# might be limited to 2-3.5G of user level memory per process, so do not
# set it too high.
innodb_buffer_pool_size=106M
# Size of each log file in a log group. You should set the combined size
# of log files to about 25%-100% of your buffer pool size to avoid
# unneeded buffer pool flush activity on log file overwrite. However,
# note that a larger logfile size will increase the time needed for the
# recovery process.
innodb_log_file_size=53M
# Number of threads allowed inside the InnoDB kernel. The optimal value
# depends highly on the application, hardware as well as the OS
# scheduler properties. A too high value may lead to thread thrashing.
innodb_thread_concurrency=8
