以前从没玩过mysql，这两天忽然心血来潮，感觉好玩，看了一点点文档，决定玩玩mysql，O(∩_∩)O哈哈~
今天在火车上，闲得无聊，找了一个windows版本的mysql，尝试免安装版的手动配置mysql。
大致思路：
1，手工编辑my.ini(linux上是my.cnf) 2，注册到windows服务 3，修改系统环境变量 4，测试
mysql5.1版本，如果用免安装版本的话，解压后，缺省会有一些配置文件模板，
昨天下载了一个5.6的免安装版本，发现里面只有一个my-default.ini，内容类似：
下面的内容是我稍微修改的：
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [client] port=3306 [WindowsMysql5.6] Server="d:/mysql5.6/bin/mysqld.ext" [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. log_bin="d:/mysql5.6/binlog/" # These are commonly set, remove the # and set as required. basedir = "d:/mysql5.6/" datadir = "d:/mysql5.6/data/" port = 3306 server_id = 1 # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
这里面看到windows下面的目录文件号居然也要用“/”，确实奇葩。
开始我用的“\”，注册服务后，启动mysql时就报错了：
D:\mysql5.6\bin>net start mysql MySQL 服务正在启动 ... MySQL 服务无法启动。 系统出错。 发生系统错误 1067。 进程意外终止。
修改成“/”后，问题解决了：
D:\mysql5.6\bin>net start mysql MySQL 服务正在启动 . MySQL 服务已经启动成功。
如果使用exe的方式安装mysql，会自动配置好环境变量。
如果用免安装的方式，那么需要手工配置环境变量：
D:\ORACLE\product\12.1.0\dbhome_1\bin;C:\Program Files (x86)\Common Files\NetSarang;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Lenovo\Fingerprint Manager Pro\;d:\mysql5.6\bin
测试一下，ok了，O(∩_∩)O哈哈~：
