MySQL服務解壓版安裝
1.環境變量配置
右鍵計算機–屬性–高級系統設置–環境變量，在系統變量中找到Path編輯，在結尾處追加你的mysql的bin文件夾地址D:\Program Files\mysql-8.0.12-winx64\bin
2.創建my.ini文件
[client]
# pipe=
socket=MYSQL
port=3306
[mysql]
no-beep
# default-character-set=
# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this
# file.
#
# server_type=3
[mysqld]
# The next three options are mutually exclusive to SERVER_PORT below.
# skip-networking
# enable-named-pipe
# shared-memory
# shared-memory-base-name=MYSQL
# The Pipe the MySQL Server will use
# socket=MYSQL
# The TCP/IP Port the MySQL Server will listen on
port=3306
# Path to installation directory. All paths are usually resolved relative to this.
basedir=D:\Program Files\mysql-8.0.12-winx64
# Path to the database root
datadir=D:\Program Files\mysql-8.0.12-winx64\data
# The default character set that will be used when a new schema or table is
# created and no character set is defined
# character-set-server=
# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB
# Set the SQL mode to strict
sql-mode=
3.配置MySQL服務
a） 用管理員身份打開cmd，進入mysql的bin文件夾。（註意要用管理員打開，否則權限不足）
b)執行：mysqld -install,顯示：Service successfully installed. 則註冊服務成功。如果要刪除服務：mysqld -remove c）MySQL數據庫在升級到5.7版本後，和之前的版本有些不一樣，沒有data文件夾，MySQL數據庫文件是保存在data文件夾中的，標準的修改方法是，打開cmd命令窗口，並且進入到MySQL安裝目錄中的bin目錄，然後輸入如下命令初始化數據：mysqld –initialize-insecure 。執行完上面命令後，MySQL會自建一個data文件夾，並且建好默認數據庫，登錄的用戶名為root，密碼為空。
d）安裝成功後就要啟動服務了，繼續在cmd中輸入net start mysql，停止服務net stop mysql。
如果失敗查看錯誤日誌，D:\Program Files\mysql-8.0.12-winx64\data下*.err日誌
4 登陸mysql服務，修改密碼
a)繼續在cmd中輸入:mysql -u root 回車，密碼為空，繼續回車，連接上mysql。
b)屏蔽權限：mysqld --skip-grant-tables.flush privileges;
c)8.0版本以上： alter user ‘root‘@‘localhost‘IDENTIFIED BY ‘123‘;註：mysql8.0以上密碼策略限制必須要大小寫加數字特殊符號，我沒碰到，修改失敗的話註意一下
8.0版本以下：set password for root@localhost =password(‘root‘);
d)FLUSH PRIVILEGES;
