1、下载server和workbench
2、安装server
2018-04-22T09:29:10.385999Z 1 [Note] A temporary password is generated for root@localhost: 8Jj)>opkXLuN
If you lose this password, please consult the section How to Reset the Root Password in the MySQL reference manual.
提示的root密码一定要记下来
- 在设置的最下面可以看到mysql选项，点击进入并启动
- 把下面两条指令复制到终端当中运行，给两个目录地址给一个名字，
目的是下一次执行可以直接执行mysql或者mysqladmin，不需要再去来回切换目录
zhaojunyandeMBP:~ zhaojunyan$ alias mysql=/usr/local/mysql/bin/mysql
zhaojunyandeMBP:~ zhaojunyan$ alias mysqladmin=/usr/local/mysql/bin/mysqladmin
zhaojunyandeMBP:~ zhaojunyan$ mysql- 终极方案
上面是个临时的，终端重启就失效了
zhaojunyandeMBP:~ zhaojunyan$ sudo vim ~/.bash_profile
zhaojunyandeMBP:~ zhaojunyan$ source ~/.bash_profile
zhaojunyandeMBP:~ zhaojunyan$ cat ~/.bash_profile
export GOPATH=/Users/zhaojunyan/go
export GOBIN=$GOPATH/bin
export MYSQLBIN=/usr/local/mysql/bin
export PATH=$PATH:$GOBIN:$MYSQLBIN
zhaojunyandeMBP:~ zhaojunyan$ mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

zhaojunyandeMBP:~ zhaojunyan$ **mysql -uroot -p**
Enter password:

mysql> set password for 'root'@'localhost' = password('root');
Query OK, 0 rows affected, 1 warning (0.01 sec)- 添加用户
命令:CREATE USER ‘username’@’host’ IDENTIFIED BY ‘password’;
说明:username - 你将创建的用户名, host - 指定该用户在哪个主机上可以登陆,如果是本地用户可用localhost, 如果想让该用户可以从任意远程主机登陆,可以使用通配符%. password - 该用户的登陆密码,密码可以为空,如果为空则该用户可以不需要密码登陆服务器.
例子: CREATE USER ‘test’@’localhost’ IDENTIFIED BY ‘123456’;
CREATE USER ‘test’@’%’ IDENTIFIED BY ‘123456’;
CREATE USER ‘test’@’%’ IDENTIFIED BY ”;
CREATE USER ‘test’@’%’;
mysql> create user 'test'@'localhost' identified by '123456';
Query OK, 0 rows affected (0.01 sec)- 查看所有用户，其实也是存在一张表里
mysql> select User,Host FROM mysql.user;
+-----------+-----------+
| User | Host |
+-----------+-----------+
| mysql.sys | localhost |
| root | localhost |
| test | localhost |
+-----------+-----------+
3 rows in set (0.00 sec)
mysql> quit- 设置与更改用户密码
命令:
SET PASSWORD FOR ‘username’@’host’ = PASSWORD(‘newpassword’)
如果是当前登陆用户用SET PASSWORD = PASSWORD(“newpassword”);
例子: SET PASSWORD FOR ‘test’@’%’ = PASSWORD(“123456”);
- 添加了用户名，可能没有操作表的权限，需要添加权限
命令:GRANT privileges ON databasename.tablename TO ‘username’@’host’
说明: privileges - 用户的操作权限,如SELECT , INSERT , UPDATE 等
如果要授予所的权限则使用ALL.
databasename - 数据库名,tablename-表名
如果要授予该用户对所有数据库和表的相应操作权限则可用*表示, 如*.*
例子: GRANT SELECT, INSERT ON test.user TO ‘test’@’%’;
GRANT ALL ON *.* TO ‘test’@’%’;
注意:用以上命令授权的用户不能给其它用户授权
如果想让该用户可以授权, 用以下命令:
GRANT privileges ON databasename.tablename TO ‘username’@’host’ WITH GRANT OPTION;
- 撤销授权
命令:
REVOKE privilege ON databasename.tablename FROM ‘username’@’host’;
说明: privilege, databasename, tablename - 同授权部分.
例子: REVOKE SELECT ON *.* FROM ‘test’@’%’;
3、安装workbench
安装后可以通过workbench创建数据库和表，也可以通过命令创建
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
4 rows in set (0.00 sec)
mysql> create database testdb;
Query OK, 1 row affected (0.00 sec)
mysql> create table person(name varchar(20), age tinyint(4));
ERROR 1046 (3D000): No database selected
mysql> use testdb;
Database changed
mysql> create table person(name varchar(20), age tinyint(4));
Query OK, 0 rows affected (0.02 sec)
mysql>
