Python3.7和數據庫MySQL 8.0.12 綠色解壓 安裝教程(一)

首先要安裝MySQL 數據庫才可以繼續安裝圖形工具SQLyog

第一步：下載解壓包》》

MYSQL官網地址：https://dev.mysql.com/downloads/file/?id=479669

 

 

綠色安裝 直接解壓即可。

第二步》》環境變量配置

解壓之后放入E盤，需在系統進行環境變量配置

 

 ==============================================================================

第三步》》mysql初始化配置

接下來連接和啟動數據庫操作：

3.1  創建初始化配置my.ini配置文件 存放根目錄下面  復制下面文檔(需修改路徑)

[mysqld]
# 設置3306端口
port=3306
# 設置mysql的安裝目錄
basedir=E:\\mysql\\mysql-8.0.12-winx64   # 切記此處一定要用雙斜杠\\，單斜杠我這里會出錯。
# 設置mysql數據庫的數據的存放目錄
datadir=E:\\mysql\\mysql-8.0.12-winx64\\Data   # 此處同上
# 允許最大連接數
max_connections=200
# 允許連接失敗的次數。這是為了防止有人從該主機試圖攻擊數據庫系統
max_connect_errors=10
# 服務端使用的字符集默認為UTF8
character-set-server=utf8
# 創建新表時將使用的默認存儲引擎
default-storage-engine=INNODB
# 默認使用“mysql_native_password”插件認證
default_authentication_plugin=mysql_native_password
[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8
[client]
# 設置mysql客戶端連接服務端時默認使用的端口
port=3306
default-character-set=utf8

 

3.2 在c:\Windows\system32 找到cmd.exe 右鍵以系統管理員身份啟動該程序 

指令路徑切換到bin目錄下輸入指令：

//生成臨時密碼

mysqld --initialize --console       

示例：

E:\mysql\mysql-8.0.12-winx64\bin>mysqld --initialize --console
2018-09-03T03:05:19.275614Z 0 [System] [MY-013169] [Server] E:\mysql\mysql-8.0.12-winx64\bin\mysqld.exe (mysqld 8.0.12) initializing of server in progress as process 7608
2018-09-03T03:05:37.017614Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: oZig3fdGSh<E
2018-09-03T03:05:50.090414Z 0 [System] [MY-013170] [Server] E:\mysql\mysql-8.0.12-winx64\bin\mysqld.exe (mysqld 8.0.12) initializing of server has completed

oZig3fdGSh<E  為系統隨機生成的臨時密碼 

3.3 安裝mysql 服務

mysqld --install

示例:

E:\mysql\mysql-8.0.12-winx64\bin>mysqld --install
Service successfully installed.

 

3.4 啟動mysql服務

net start mysql

示例:

E:\mysql\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。

 

3.5 進入mysql  輸入以下指令之后 需要輸入臨時密碼

mysql -u root -p

示例:

E:\mysql\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password: ************
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

 

3.6 修改臨時密碼

修改密碼為root

alter user user() identified by "root";

示例:

mysql> alter user user() identified by "root";
Query OK,0 rows affected (0.25 sec)

修改完密碼 退出數據庫操作

mysql> exit
Bye

 

3.7 驗證密碼

E:\mysql\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password: ****
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 10

ok mysql安裝完成了密碼也修改成功了      命令行操作麻煩，推薦使用圖形化工具SQLyog。
