安裝好MySQL服務後添加環境變量：

#vi /etc/profile
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

#source /etc/profile

1.數據庫指令：(由於自己習慣用service,需安裝指定工具net-tools)

# service mysqld start 啟動MySQL
# service mysqld restart 重啟MySQL
# service mysqld stop 停止MySQL

2.進入MySQL表單操作

# mysql -h 127.0.0.1-u root -p123456; 進入MySQL(設置好相應密碼後)
MySQL> show databases; 列出數據庫
MySQL> create database aa; 創建數據庫XXX

MySQL> use aa; 使用數據庫databaseName
MySQL> show tables; 列出表單

MySQL> create table mytablename (ID int auto_increment not null primary key,usename varchar(20),password varchar(64),sex varchar(10),address varchar(20)); 創建表單
MySQL> drop table mytablename ; 刪除表單
MySQL> drop database aa; 刪除數據庫

3.增刪改查

MySQL> insert into mytablename values(‘‘,‘zhangsan‘,‘123456‘,‘fomale‘,‘guiyanag‘); 插入

MySQL> select * from mytablename ; 查找驗證結果
MySQL> select * from mytablename where ID = ‘1‘; 精準查找

MySQL> update mytablename set address = ‘shanghai‘ where username = ‘zhangsan‘; 修改zhangsan的address為shanghai

MySQL> delete from mytablename where ID = ‘1‘; 刪除記錄

新增本地特權用戶

grant select on database.* to czl@‘localhost‘ identity by ‘password‘;


用戶名user_1 密碼是123456

可以自任何PC上登錄這個用戶對數據庫操作(舉一種方法)

MySQL> grant select,insert update,delete on *.* to user_1@"%" identity by "123456";


創建只有在本機才能操作數據庫的用戶

用戶名user_2 密碼是123456

MySQL> grant select,insert update,delete on *.* to user_2@localhost identity by "123456";

登錄數據庫庫

MySQL> -u user_1 -p -h IP地址;


另外附上常用的一些命令：

其它的mysql數據庫相關的操作如下

(1) 創建數據庫czlmysql> create database czl;
(2) 制定czl數據庫為當前默認數據庫 mysql> use czl;
(3) 在czl數據庫中創建表customers mysql> create table customers(userid int not null, username varchar(20) not null);
(4) 顯示數據庫列表 mysql> show databases;
(5)顯示數據庫中的表 mysql> show tables;
(6)刪除表customers mysql> drop table customers;
(7)顯示customers表的結構 mysql> desc customers;
(8) 向customers表中插入一條記錄 mysql> insert into customers(userid, username) values(1, ‘chy‘);
(9) 讓操作及時生效; mysql> commit;
(10) 查詢customers中的記錄 mysql> select * from customers;
(11) 更新表中的數據 mysql> update customers set username=‘DennisHu‘ where userid=1;
(12) 刪除表中的記錄 mysql> delete from customers;
(13)授予chy用戶訪問數據庫的權限 # grant select, insert, update, delete on *.* to chy@"localhost" identified by "123456";
