本文介紹的是MySQL-8.0.12 windows安裝
下載
安裝
下載完成，將檔案解壓到你想要安裝的盤裡。這裡我安裝到了D盤。之後以管理員身份執行DOS視窗。
進入到mysql的bin資料夾
D:\mysql-8.0.12-winx64\bin>
my.ini
- 在mysql-8.0.12-winx64的資料夾下建立一個名為data的空資料夾。
- bin目錄中建立一個my.ini的檔案，內容為
[mysql] # 設定mysql客戶端預設字符集 default-character-set=utf8mb4 [mysqld] #設定3306埠 port = 3306 # 設定mysql的安裝目錄 basedir=D:/mysql-8.0.12-winx64 # 設定mysql資料庫的資料的存放目錄 datadir=D:/mysql-8.0.12-winx64/data # 允許最大連線數 max_connections=200 # 服務端使用的字符集預設為8位元編碼的latin1字符集 character-set-server=utf8 # 建立新表時將使用的預設儲存引擎 default-storage-engine=INNODB default_authentication_plugin=mysql_native_password
執行命令
依次執行安裝命令 mysqld --initialize-insecure、mysqld -install
D:\mysql-8.0.12-winx64\bin>mysqld --initialize-insecure
D:\mysql-8.0.12-winx64\bin>mysqld -install
Service successfully installed.
啟動服務 net start mysql
D:\mysql-8.0.12-winx64\bin>net start mysql MySQL 服務正在啟動 .... MySQL 服務已經啟動成功。
此時mysql沒有密碼，需要進行設定密碼，輸入：mysqladmin -u root password root
D:\mysql-8.0.12-winx64\bin>mysqladmin -u root password root
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
登陸
D:\mysql-8.0.12-winx64\bin>mysql -uroot -proot
mysql: [Warning] Using a password on the command line interface can be insecure.

由於8.0以上使用者密碼方式為caching_sha2_password，Navicat無法登陸，更改ROOT使用者的native_password密碼
mysql8.0以上密碼策略限制必須要大小寫加數字特殊符號
mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '[email protected]';
Query OK, 0 rows affected (0.15 sec)
