win7 64位下如何安装配置mysql

Posted 2023-03-08

　　1、 安装：
　　1先将mysql-noinstall-5.1.66-winx64.zip解压缩到 d:\\appspace\\mysql
　　2将其中的data 文件夹移动到d:/appspace/mysqlData 即mysql的 data路径为：d:/appspace/mysqlData/data
　　3my.ini配置文件有2个可选择的位置：
　　打开E:\\appSpace\\mysql \\ my-large.ini (如果后面mysql出现1067错误，启动不了的话，可试着用my-huge.ini或其他), 在最后加上如下几行，然后另存为my.ini(C:\\Windows).
　　#--------------------------------------------------------
　　[mysqld]
　　basedir=d:/appspace/mysql
　　datadir=d:/appspace/mysqlData/data
　　default-character-set=utf8
　　[WinMySQLAdmin]
　　Server=d:/appspace/mysql/bin/mysqld.exe
　　#default-character-set=utf8
　　[client]
　　default-character-set=utf8
　　#--------------------------------------------------------
　　4可以在mysql中查看设定的字符集（一定要在[mysqld] 中设定utf-8）：
　　mysql> show variables like \'character%\';
　　+--------------------------+-----------------------------------+
　　| Variable_name | Value |
　　+--------------------------+-----------------------------------+
　　| character_set_client | utf8 |
　　| character_set_connection | utf8 |
　　| character_set_database | utf8 |
　　| character_set_filesystem | binary |
　　| character_set_results | utf8 |
　　| character_set_server | utf8 |
　　| character_set_system | utf8 |
　　| character_sets_dir | d:\\appspace\\mysql\\share\\charsets\\ |
　　+--------------------------+-----------------------------------+
　　2 配置服务(命令行必须以administrator身份运行)
　　1）将MySQL 添加到服务中。
　　在Windows Run中输入cmd，这时上面有提示（cmd.exe），右键单击cmd.exe, 选择Run as administrator，进入路径： d:/appspace/mysql /bin>
　　输入 mysqld --install MySQL --defaults-file="C:\\Windows\\my.ini"
　　要指定defaults-file.
　　命令行中输入services.msc回车，可以看到MySQL已被添加到Services中，
　　Path to executable中的内容为
　　d:\\appspace\\mysql\\bin\\mysqld --defaults-file=C:\\windows\\my.ini MySQL
　　2）启动MySQL
　　在MySQL Service中点击Start按钮，或者在命令行（Run as administrator）中输入 net start mysql.
　　如果出现1067错误，启动不了，则重新检查my.ini文件（前面有描述）
　　3）关闭MySQL
　　在MySQL Service中点击Stop按钮，或者在命令行（Run as administrator）中输入 net stop mysql.
　　4）删除mysql服务
　　mysqld –remove
　　3 环境变量
　　将d:\\appspace\\ mysql\\bin添加到Path中。

　　4 操作
　　登录数据库:
　　C:\\Users\\zhang10>mysql -u root -p
　　Enter password: *** (密码初始值可设置为root或者为空)
　　进入mysql后，命令后以分号结尾。
　　显示所有的数据库模式:
　　mysql> show databases;

　　新建一个数据库模式，指定编码utf-8，否则会出现乱码。
　　create database md11uft8 character set utf8;

　　选中此数据库md11utf8：
　　mysql> use md11utf8;

　　创建一个表：
　　mysql> create table basicinfo (id int primary key auto_increment, name varchar(30) not null, age int not null);
　　插入数据：
　　mysql> insert into basicinfo(id, name, age) values(\'1\',\'张三\',\'30\');
　　mysql> insert into basicinfo(id, name, age) values(\'3\',\'李四\',\'25\');
　　查询：
　　mysql> select * from basicinfo;
　　+----+------+-----+

　　| id | name | age |

　　+----+------+-----+

　　| 1 | | 30 |

　　| 3 | | 25 |

　　+----+------+-----+
　　可看到name中的值没有显示（中文显示不了）。
　　在MySQL workbench中插入值，查询会正确显示。
　　但是在命令行中查询显示乱码（DOS不支持UTF8从MYSQL中显示），解决如下：
　　mysql> set names gbk;

　　修改root的密码：
　　mysql>use mysql；
　　mysql>update user set Password=password(\'newpassword\') where User=\'root\';
　　mysql>flush privileges; 参考技术A MYSQL软件安装
安装：
打开安装包,一般都是点“下一步Next”。
在选择安装类型里，选择“自定义安装Custom”。
配置：
选择MySQL配置向导“Launch the MySQL Instance Configuration Wizard”
一般都是点“下一步Next”。
连接数目上，选择“Online Transaction Processing(OLTP)”，默认连接上限500个；或者选择“Manual Setting（自己设置连接上限）”
对MySQL默认数据库语言编码进行设置，选“Manual Selected Default Character Set/Collation”,在Character Set下拉框里选择“UTF8”
在带有“Include Bin Directory in Windows PATH（把MySQL配置到环境变量PATH中）” 的窗口里，全部打上√
设置超级管理员root账号的密码
enable root access from remote machines 勾选（从远程机器上启用根访问）
Execute ---> Finish 参考技术B 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：

# The default storage engine that will be used whencreate new tables when
default-storage-engine=INNODB

# Set the SQL mode to strict

# 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。具体操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;

下载MySQL Community Server 5.6.13

解压MySQL压缩包
将以下载的MySQL压缩包解压到自定义目录下,我的解压目录是:
"D:\\Program Files\\MySQL\\mysql-5.6.13-win32"

添加环境变量

操作如下：

1）右键单击我的电脑->属性->高级系统设置(高级)->环境变量
点击系统变量下的新建按钮
输入变量名：MYSQL_HOME
输入变量值：D:\\Program Files\\mysql-5.6.11-winx64
#即为mysql的自定义解压目录。

2）选择系统变量中的Path
点击编辑按钮
在变量值中添加变量值：%MYSQL_HOME%\\bin
注意是在原有变量值后面加上这个变量，用;隔开，不能删除原来的变量值，
