windows 免安装mysql

一、下载免安装压缩包

二、本地环境配置

  1. 把zip包解压到需要安装的目录 ,会发现缺少data文件夹以及my.ini的配置文件

   2.添加data文件夹以及my.ini环境配置

 

    3. my.ini文件中添入一下内容并修改下面两项

    basedir = F:/soft/mysql-5.7.25                        是你解压之后的根目录

    datadir = F:/soft/mysql-5.7.25/data                是你解压之后的根目录下的data

        注意:要是 / 而不是 \

[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的缓存,可以根据实际情况调整大小,我这里采取默认值
  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.
  #mysql根目录
  basedir = F:/soft/mysql-5.7.25
  #数据存储目录
  datadir = F:/soft/mysql-5.7.25/data
  #端口号,默认为3306
  port = 3306
  #服务实例的唯一标识,这个是做集群的时候使用,单例可以不配置
# 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.
  #把这些缓存都放开,可以提高性能,加快速度
  join_buffer_size = 128M
  sort_buffer_size = 2M
  read_rnd_buffer_size = 2M 
  #配置一下服务端的字符集
  character_set_server=utf8mb4
  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
  
  
#配置一下客户端的字符集
[client]   
  default-character-set=utf8mb4

   4.初始化数据库 以管理员身份运行cmd  进入到bin目录下

    mysqld --initialize  执行完成之后会在data下生成一些文件

   5.注册为windows服务

      mysqld --install MySQL57        #install后面是服务的名字,我们这里以MySQL57作为mysql5.7的服务名

   6.启动mysql 登录并修改密码

   mysql -u root -p

   这次的登录密码并不是空,而是在data文件夹下有一个.err结尾的文件,如下图所示

 

  

     找到之后可以正常登录。


  7.修改密码并刷新  分号保留  修改成功之后可以正常登录

  ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘123456’;
  FLUSH PRIVILEGES;
