1.下載mysql社群版
2.解壓到D:\Program Files
3.在D:\Program Files\mysql-5.7.18-winx64\bin下，新建檔案my.ini,內容如下：

[client]
 port=3306
 default-character-set=utf8

 [mysqld]
 bind-address = 127.0.0.1
 port=3306
 character_set_server=utf8
 basedir  ="D:\Program Files\mysql-5.7.18-winx64"
 datadir  ="D:\Program Files\mysql
 
-5.7.18-winx64\data"
 tmpdir   ="D:\Program Files\mysql-5.7.18-winx64\data"
 socket   ="D:\Program Files\mysql-5.7.18-winx64\data\mysql.sock"
 log-error="D:\Program Files\mysql-5.7.18-winx64\data\mysql_error.log"

 max_connections=100
 table_open_cache=256
 query_cache_size=1M
 tmp_table_size=32M
 thread_cache_size=8

 innodb_data_home_dir="D:\Program
 
 Files\mysql-5.7.18-winx64\data\"
 innodb_flush_log_at_trx_commit =1
 innodb_log_buffer_size=128M
 innodb_buffer_pool_size=128M
 innodb_log_file_size=10M
 innodb_thread_concurrency=16
 innodb-autoextend-increment=1000

 join_buffer_size = 128M
 sort_buffer_size = 32M
 read_rnd_buffer_size = 32M
 max_allowed_packet = 32M
 explicit_defaults_for_timestamp=true

 sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
 

4.配置C:\WINDOWS\system32\drivers\etc\hosts，預設是註釋掉的，去掉註釋：

127.0.0.1       localhost

5.在D:\Program Files\mysql-5.7.18-winx64目錄下新建data資料夾，必須為空。
6.開啟cmd，cd到D:\Program Files\mysql-5.7.18-winx64\bin，執行如下命令

mysqld --initialize-insecure
mysqld -install

7.啟動mysql服務，如果沒有啟動的話.net start mysql。
8.在cmd中，使用命令mysql -u root -p,回車進入mysql>命令提示符。
9.修改root密碼

mysql> set password=password('123456');
