Question

win764位系统怎么安装mysql

Answer 1

1、下载MySQL5.7.10的压缩包并解压，打开Windows命令行，进入MySQL5.7.10目录下的bin文件夹

命令： 

C:\Users\Administrator>d: #进入D盘
D:\>cd mysql-5.7.10-winx64/bin #进入MySQL bin文件夹

2、安装MySQL服务

命令：

D:\mysql-5.7.10-winx64\bin>mysqld install #安装MySQL服务

3、初始化MySQL data目录。
命令：

D:\mysql-5.7.10-winx64\bin>mysqld --initialize-insecure #生成空密码

注：使用–initialize-insecure生成空密码。使用–initialize生成随机初始默认密码，生成的随机初始默认密码在data下面的日志文件中，比如：[Note] A temporary password is generated for root@localhost: %j0q/!AvSsbs。

4、MySQL服务的启动与停止

命令：

D:\mysql-5.7.10-winx64\bin>net stop mysql #关闭MySQL服务

命令：

D:\mysql-5.7.10-winx64\bin>net start mysql #启动MySQL服务

注：修改密码时，可以参考“MySQL设置登陆密码”和“MySQL忘记root密码怎么办？”。在MySQL5.7.10中，使用SQL语句：“update user set password=PASSWORD(“123456″) where user=”root”;”，会报错“ Unknown column ‘password’ in ‘field list’”，因为5.7密码的字段叫authentication_string，正确的SQL语句为：“update user set authentication_string=PASSWORD(“123456″) where user=”root”;”。

Answer 2

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;
mysql> QUIT
