对于Windows的MySQL的安装其实很简单。个人推荐使用免安装版的MySQL，这种版本只要下来，解压缩后配置一下就可以使用了。而对那种安装包则就比较麻烦，本篇也不做介绍。因为周围有许多人的MySQL安装使用安装程序，而安装到一半，配置不会弄，MySQL数据库也弄的怪怪的。
第一步，下载MySQL的免安装版压缩包
好了，对于MySQL的免安装程序，我们先要下载一个MySQL的压缩包。下载地址：或者。
说明：在MySQL下载的时候，会有个让你login或sign up的按钮，不用注册了，看下方有个
No thanks, just start my download.的链接。点击可直接下载，不用登录。 对于解压缩出来的MySQL，有几个配置文件样例，有my-small.ini、my-huge.ini等等，我们只要复制其中的一个，并命名为my.ini。
| 1 2 3 4 | Small: System has Medium: System has at least 64MB memory Large: System has at least 512MB memory and the server will run mainly MySQL. Huge: System has at least 1GB memory and the server will run mainly MySQL. Heavy: System has at least 4GB memory and the server will run mainly MySQL. |
第二步，配置MySQL
将第一步复制的配置文件my.ini打开，我们需要修改一下basedir（MySQL数据库的文件夹）和datadir（MySQL数据库的数据目录）。如下，
| 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 071 072 073 074 075 076 077 078 079 080 081 082 083 084 085 086 087 088 089 090 091 092 093 094 095 096 097 098 099 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 | # Example MySQL config file for medium systems. # # This is for a system with little memory (32M - 64M) where MySQL plays # an important part, or systems up to 128M where MySQL is used together with # other programs (such as a web server) # # You can copy this file to # /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options (in this # installation this directory is C:\mysql\data) or # ~/.my.cnf to set user-specific options. # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3306 socket = /tmp/mysql.sock #skip-locking key_buffer = 16M max_allowed_packet = 1M table_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M # set basedir to your installation path basedir =E:/Program Files (x86)1/mysql-5.5.27-winx64 # set datadir to the location of your data directory datadir =E:/Program Files (x86)1/mysql-5.5.27-winx64/data # Don't listen on a TCP/IP port at all.

However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # Point the following paths to different dedicated disks #tmpdir = /tmp/ #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using BDB tables #bdb_cache_size = 4M #bdb_max_lock = 10000 # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = C:\mysql\data/ #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = C:\mysql\data/ #innodb_log_arch_dir = C:\mysql\data/ # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 16M #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 5M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout |
将这两处的地址换成自己的MySQL的地址，已经date目录。注意斜线的方向，使用E:/Program Files/mysql-5.5.27-winx64或者E:\\Program Files\\mysql-5.5.27-winx64。仅有这两处需要改动，其他不必改动了，除非特殊需要。
第三步，启动MySQL
要启动MySQL也很简单，打开命令提示符。输入一下两个命令
| 1 2 | cd /d E:\Program Files\mysql-5.5.27-winx64\bin\ mysqld --console |
会出现一下内容就成功了。
| 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 | 130317 20:11:05 [Note] Plugin 'FEDERATED' is disabled. 130317 20:11:05 InnoDB: The InnoDB memory heap is disabled 130317 20:11:05 InnoDB: Mutexes and rw_locks use Windows interlocked functions 130317 20:11:05 InnoDB: Compressed tables use zlib 1.2.3 130317 20:11:05 InnoDB: Initializing buffer pool, size = 128.0M 130317 20:11:05 InnoDB: Completed initialization of buffer pool 130317 20:11:05 InnoDB: highest supported file format is Barracuda. 130317 20:11:06 InnoDB: Waiting for the background threads to start 130317 20:11:07 InnoDB: 1.1.8 started; log sequence number 14128205 130317 20:11:07 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 130317 20:11:07 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 130317 20:11:07 [Note] Server socket created on IP: '0.0.0.0'. 130317 20:11:07 [Note] Event Scheduler: Loaded 0 events 130317 20:11:07 [Note] mysqld: ready for connections. Version: '5.5.27-log' socket: '' port: 3306 MySQL Community Server (GPL) |
为了以后的方便，将里面的内容保存到startmysql.bat文件里，以后只要双击bat就可以运行mysql了。
第四步：更改MySQL密码
默认MySQL的root密码为空的，在某些地方，密码不能输入为空，所以需要更改密码。
首先先启动MySQL数据库，可以使用上面的bat启动MySQL。
然后根据下面的命令进行更改
| 1 2 3 4 | mysql -u root -p #从命令行中进入mysql的客户端 use mysql; #使用mysql这个数据库 update user set password=password( "root" ) where user= "root" ; #对root密码进行更改 FLUSH PRIVILEGES; #刷新一下权限 |
安装到Windows service服务开机自动启动
如果需要将MySQL开机自动运行，并且以服务的形式存在，那么按照本方法进行即可。以服务的形式打开MySQL，就不用再适用上面的批处理文件了。
先停止MySQL Server的运行。以管理员方式运行命令提示符
向WINDOWS添加服务
| 1 2 | E:\Program Files\mysql-5.5.27-winx64\bin>mysqld --install MySQL5.5 Service successfully installed. |
使用mysqld 并使用参数--install MySQL5.5，说明向服务注册一个叫MySQL5.5的服务名，如果不加服务名，则使用默认的MySQL作为服务名。
注意：使用
--install 参数添加的服务为开机自动启动的。如果想要使用手工启动，那么使用参数 --install-manual代替。命令 mysqld --install-manual添加服务，需要手工启动服务。 启动MYSQL服务
第二步只是向Windows服务添加了一个MySQL5.5的服务，但是并没有启动。可以到Windows服务里启动，或者使用命令行(需要管理员权限)
| 1 2 3 | C:\> net start MySQL5.5 MySQL5.5 服务正在启动 . MySQL5.5 服务已经启动成功。 |
从服务中停止MYSQL服务
| 1 2 3 | C:\> net stop MySQL5.5 MySQL5.5 服务正在停止. MySQL5.5 服务已成功停止。 |
删除WINDOWS的MYSQL服务
| 1 2 | E:\Program Files\mysql-5.5.27-winx64\bin>mysqld --remove MySQL5.5 Service successfully removed. |
