window上mysql绿色版安装

最近搞黑苹果。。。所以把所有的系统重新装了一遍，导致很多环境都是重新部署， 所以整理了之前的一些资料，这篇是关于MySQL绿色版安装的地方。

一、绿色版安装

1. 下载MySQL 5.7，地址：http://dev.mysql.com/downloads/mysql/ （选择32位或者64位版本需根据自身PC情况）

2. 下载后解压，比如我的目录结构是：

 

3. 配置Path路径：系统属性 => 高级 => 高级 => 系统变量 => path后添加 F:\CSoft\MySQL-5.7\bin

4. 修改my-default.ini，此文件是初始化信息：

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.7/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.[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# These are commonly set, remove the # and set as required.basedir = F:\CSoft\MySQL-5.7datadir = F:\CSoft\MySQL-5.7\dataport = 3306# server_id = .....# 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 # !o>UZ!e(h6(m  初始化的密码

 

5. 系统管理员模式运行cmd 输入如下命令

C:\Users\LCF>F:          //切换到F目录F:\>cd CSoft\MySQL-5.7\bin   //进入bin目录F:\CSoft\MySQL-5.7\bin>mysqld --install   //安装MYSQL服务Service successfully installed.  //提示服务安装成功The current server installed: F:\CSoft\MySQL-5.7\bin\mysqld MySQLF:\CSoft\MySQL-5.7\bin>mysqld --initialize --console  //根据配置文件初始化，此时会有一大堆消息，(注意最后的消息:2016-07-13T14:21:39.268917Z 1 [Note] A temporary password is generated for root@localhost: !o>UZ!e(h6(m  )后面这个是密码待会儿登录使用的。F:\CSoft\MySQL-5.7\bin>net start mysql  //启动mysql服务MySQL 服务正在启动 .MySQL 服务已经启动成功。F:\CSoft\MySQL-5.7\bin>mysql -uroot -p  //登录mysqlEnter password: ************   //密码就是输入的密码mysql> set password=password('123456');     //修改密码Query OK, 0 rows affected, 1 warning (0.00 sec)

目前为止成功安装。

删除window中的mysql服务

进入“控制面板->管理工具->服务”查看才发现，虽然MySQL已经卸载了，但是mysql服务仍然残留在系统服务里。
又不想改服务名，改怎么办呢。
后来上百度搜索发现，只要在CMD里输入一跳命令就可以将服务删除：

sc delete mysql //这里的mysql是你要删除的服务名

这样一来服务就被删除了，进入服务里查看确实没有mysql服务了，OK重新安装数据库吧。

二、中文乱码修改

1. 从服务端进行修改

show variables like "%char%";  

然后可能显示如下信息，注意红色部分，不同的用户可能实际情况不同，但是需要保证除了 filesystem为binary外，其他都为utf8：

+--------------------------+---------------+  | Variable_name | Value |  +--------------------------+---------------+  | character_set_client | gbk |  | character_set_connection | gbk |  | character_set_database | utf8 |  | character_set_filesystem | binary |  | character_set_results | gbk |  | character_set_server | utf8 |  | character_set_system | utf8 |  +--------------------------+-------------+  

 

2. 通过如下SQL语句进行修改，全部设置为utf8即可：

#设置数据库编码信息SET character_set_client='utf8';  SET character_set_connection='utf8';  SET character_set_database ='utf8';  SET character_set_results='utf8';  SET character_set_server='utf8'; 

3、SQL连接字符串加上?useUnicode=true&characterEncoding=utf-8

jdbc.url = jdbc:mysql://localhost:3306/bsframe?useUnicode=true&characterEncoding=utf-8

一般按照上述步骤后，就不会出现乱码了!

三、修改为任意用户可以连接

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;FLUSH PRIVILEGES;

 这里的yourpassword 是你设定的密码，请自行修改。

Doing is better than nothing
