.1、下载社区版本的服务端
2、将压缩文件解压到对应的目录
3、配置环境变量
4、新建my.ini文件
解压包里是没有my-dafault.ini或自带my.ini文件，需自己创建放到解压目录下。编辑写入以下信息：
# 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. [mysql] #max_sp_recursion_depth=100 [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 = D:\MySQL\mysql-5.6.24-win32.1432006610\mysql-5.6.24-win32 # datadir = D:\MySQL\mysql-5.6.24-win32.1432006610\mysql-5.6.24-win32\data # port = ..... # 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 character-set-server=utf8 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES max_sp_recursion_depth = 100
5、mysql初始化
以管理员权限打开cmd命令窗口，切换到”F:\mysql-5.7.21-winx64\bin”路径下，输入指令：
mysqld --initialize --user=mysql --console
该命令会在mysql-5.7.21-winx64目录下创建data文件夹及初始数据库，生成root用户和临时密码，红色标注部分多留意。
6、安装mysql服务
继续在窗口输入指令：
mysqld install MySQL --defaults-file="F:\mysql-5.7.21-winx64\my.ini"
路径是你my.ini文件的绝对路径，此时如果遇到错误没能安装成功，请用管理员身份运行cmd.exe程序再试，正确安装如下图：
7、启动mysql服务
在命令行窗口继续输入：
net start mysql
启动成功，会出现下面的截图。如果服务一直处于启动中，说明上一步的操作有误，核实my.ini文件路径是否正确
如需修改密码和配置远程连接，请参考我的安装mysql博客，博客链接https://www.cnblogs.com/mituxiaogaoyang/p/8655952.html
