mysql安装教程多大

mysql安装教程64位的是334.7M。

MySQL关是一种关系数据库管理系统，所使用的 SQL 语言是用于访问数据库的最常用的标准化语言，其特点为体积小、速度快、总体拥有成本低。

尤其是开放源码这一特点，在 Web应用方面 MySQL 是最好的 RDBMS(Relational Database Management System：关系数据库管理系统)应用软件之一。

验证 MySQL 安装：

在成功安装 MySQL 后，一些基础表会表初始化，在服务器启动后，你可以通过简单的测试来验证 MySQL 是否工作正常。

使用 mysqladmin 工具来获取服务器状态：

使用 mysqladmin 命令来检查服务器的版本, 在 linux 上该二进制文件位于 /usr/bin 目录，在 Windows 上该二进制文件位于C:\mysql\bin 。

使用 MySQL Client(Mysql客户端) 执行简单的SQL命令：

你可以在 MySQL Client(Mysql客户端) 使用 mysql 命令连接到 MySQL 服务器上，默认情况下 MySQL 服务器的登录密码为空。

Mysql安装后需要做的：

Mysql安装成功后，默认的root用户密码为空，你可以使用以下命令来创建root用户的密码。

1、 MySQL Community Server 5.6.10

2、解压到d:\MySQL.（路径自己指定）

3、在d:\MySQL下新建my.ini配置文件，内容如下：

# CLIENT SECTION

#----------------------------------------------------------------------

#

# The following options will be read by MySQL clientapplications.

# Note that only client applications shipped by MySQLare guaranteed

# to read this section. If you want your own MySQLclient program to

# honor these values, you need to specify it as anoption during the

# MySQL client library initialization.

[client]

port=3306

[mysql]

default-character-set=gbk

# 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 usuallyresolved relative to this.

basedir="d:\MySQL\"

#Path to the database root

datadir="d:\MySQL\Data"

[WinMySQLadmin]

Server="d:\MySQL\bin\mysqld.exe"

# The default character set that will be used when anew schema or table is

# created and no character set is defined

default-character-set=gbk

# The default storage engine that will be used whencreate 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 MySQLserver will

# allow. One of these connections will be reserved fora user with

# SUPER privileges to allow the administrator to logineven if the

# connection limit has been reached.

max_connections=100

# Query cache is used to cache SELECT results andlater return them

# without actual executing the same query once again.Having the query

# cache enabled may result in significant speedimprovements, if your

# have a lot of identical queries and rarely changingtables. See the

# "Qcache_lowmem_prunes" status variable tocheck if the current value

# is high enough for your load.

# Note: In case your tables change very often or ifyour queries are

# textually different every time, the query cache mayresult 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 mysqldrequires.

# Therefore you have to make sure to set the amount ofopen 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) temporarytables. If a table

# grows larger than this value, it is automaticallyconverted to disk

# based table This limitation is for a single table.There can be many

# of them.

tmp_table_size=26M

# How many threads we should keep in a cache forreuse. When a client

# disconnects, the client's threads are put in thecache if there aren't

# more than thread_cache_size threads frombefore. This greatly reduces

# the amount of thread creations needed if you have alot of new

# connections. (Normally this doesn't give a notableperformance

# improvement if you have a good threadimplementation.)

thread_cache_size=8

#*** MyISAM Specific options

# The maximum size of the temporary file MySQL isallowed to use while

# recreating the index (during REPAIR, ALTER TABLE orLOAD DATA INFILE.

# If the file-size would be bigger than this, theindex will be created

# through the key cache (which is slower).

myisam_max_sort_file_size=100G

# If the temporary file used for fast index creationwould be bigger

# than using the key cache by the amount specifiedhere, 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 tocreate the index.

myisam_sort_buffer_size=52M

# Size of the Key Buffer, used to cache index blocksfor 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 ifyou're not using

# MyISAM tables, you should still set it to 8-64M asit will also be

# used for internal temporary disk tables.

key_buffer_size=40M

# Size of the buffer used for doing full table scansof 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 rebuildthe index in

# REPAIR, OPTIMZE, ALTER table statements as well asin LOAD DATA INFILE

# into an empty table. It is allocated per thread sobe careful with

# large settings.

sort_buffer_size=256K

#*** INNODB Specific options ***

innodb_data_home_dir="d:\MySQL\Data\INNODB\"

# Use this option if you have a MySQL server withInnoDB support enabled

# but you do not plan to use it. This will save memoryand disk space

# and speed up some things.

#skip-innodb

# Additional memory pool that is used by InnoDB tostore 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 needto change this

# value. SHOW INNODB STATUS will display the currentamount used.

innodb_additional_mem_pool_size=2M

# If set to 1, InnoDB will flush (fsync) thetransaction logs to the

# disk at each commit, which offers full ACIDbehavior. If you are

# willing to compromise this safety, and you arerunning small

# transactions, you may set this to 0 or 2 to reduce diskI/O to the

# logs. Value 0 means that the log is only written tothe log file and

# the log file flushed to disk approximately once persecond. Value 2

# means the log is written to the log file at eachcommit, but the log

# file is only flushed to disk approximately once persecond.

innodb_flush_log_at_trx_commit=1

# The size of the buffer InnoDB uses for buffering logdata. As soon as

# it is full, InnoDB will have to flush it to disk. Asit is flushed

# once per second anyway, it does not make sense tohave it very large

# (even with long transactions).

innodb_log_buffer_size=1M

# InnoDB, unlike MyISAM, uses a buffer pool to cacheboth indexes and

# row data. The bigger you set this the less disk I/Ois needed to

# access data in tables. On a dedicated databaseserver you may set this

# parameter up to 80% of the machine physical memorysize. Do not set it

# too large, though, because competition of thephysical 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 perprocess, so do not

# set it too high.

innodb_buffer_pool_size=77M

# Size of each log file in a log group. You should setthe combined size

# of log files to about 25%-100% of your buffer poolsize to avoid

# unneeded buffer pool flush activity on log fileoverwrite. However,

# note that a larger logfile size will increase thetime needed for the

# recovery process.

innodb_log_file_size=39M

# Number of threads allowed inside the InnoDB kernel.The optimal value

# depends highly on the application, hardware as wellas the OS

# scheduler properties. A too high value may lead tothread thrashing.

innodb_thread_concurrency=8

*****************配置文件结束*********************

配置文件也放在了附件里，大家可以根据需要修改。

重点是以下配置，其中datadir的目录名称必须是data，并且好像必须是MySQL目录下的data.之前自己制定了其他目录，一直出现1067的错误。

#Path to installation directory. All paths are usuallyresolved relative to this.

basedir="d:\MySQL\"

#Path to the database root

datadir="d:\MySQL\Data"

4、在windows环境变量里加入以下内容（方便执行命令行命令）

新建MYSQL_HOME="d:\MySQL\"

在Path里加入%MYSQL_HOME%\bin

5、将mysql注册为windows系统服务。具体 *** 作是在命令行中执行以下命令：

mysqld install MySQL --defaults-file="d:\MySQL\my.ini"

移除服务为 mysqld remove

6、第5步成功后，在命令行启动mysql

c:>net start mysql

7、修改root的密码为62386997

方法一：

c:>mysql –uroot

mysql>showdatabases

mysql>use mysql

mysql>UPDATE user SET password=PASSWORD("62386997") WHEREuser='root'

mysql>FLUSH PRIVILEGES

mysql>QUIT
