windows 7 64位下配置mysql64位免安装版
文章分类:数据库
1、下载http://pan.baidu.com/s/1jGf5nUI
2、解压到D:\MySQL（路径自己指定） 文件夹不要带中文，最好改成Mysql
3、在D:\MySQL下将my-default.ini改成my.ini配置文件并将内容改成，如下：
<code class=" hljs vbscript">*****************配置文件开始********************* # MySQL Server Instance Configuration File # ---------------------------------------------------------------------- # Generated by the MySQL Server Instance Configuration Wizard # # # Installation Instructions # ---------------------------------------------------------------------- # # # 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=gbk # SERVER SECTION # ---------------------------------------------------------------------- # # The following options will be read by the MySQL Server.

All paths are usually resolved 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 a new schema or table is # created and no character set is defined default-character-set=gbk # 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=26M # 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=52M # 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=40M # 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 *** innodb_data_home_dir="E:\Program Files\MySQL\Data\INNODB\" # 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=2M # 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=1M # 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=77M # 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=39M # 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 *****************配置文件结束*********************
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。
<code class=" hljs lasso">#Path to installation directory. All paths are usually resolved 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：
切换到bin目录后 ,执行mysqld –install 必须切换到bin目录
C:\Windows\system32>cd /
C:>d:
D:\cd Mysql\bin
D:\cd Mysql\bin>mysqld –install
Service successfully installed.
D:\cd Mysql\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
“`
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111111
用mysqladmin
mysqladmin -u root password “111111”
如果root已经设置过密码，采用如下方法
mysqladmin -u root password oldpass “newpass”
