二.配置mysql.

1.進入mysql文件夾

cd /var/lib/mysql

2.將/var/lib路徑下的mysql文件用戶組設爲mysql.

sudo chgrp -R mysql /var/lib/mysql

3.修改文件權限爲可讀可寫可運行.

sudo chmod -R 770 /var/lib/mysql

4.開啓mysql服務

sudo service mysqld start

顯示mysql數據庫正在初始化,之後開啓mysql服務成功.

Initializing MySQL database:  Installing MySQL system tables...
...
...
...
Starting mysqld:                                           [  OK  ]

5.設置mysql登錄的賬號和密碼.

/usr/bin/mysqladmin -u root password root

以上第一個root爲賬號名,第二個root爲密碼

6.連接mysql

mysql -u root -p

會顯示:

Enter password:

輸入剛剛設置的密碼root.
之後顯示mysql歡迎提示和版本信息.

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.5.59 MySQL Community Server (GPL)

7.顯示當前所有的數據庫.

mysql>show databases;

顯示

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+

8.使用mysql.

mysql>use mysql

9.創建新賬號和密碼,授予遠程登錄的任意ip全部權限.

grant all PRIVILEGES on *.* to root@'%' identified by 'root';

解釋:
all PRIVILEGES指所有權限,也可以給予部分權限,如:
select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等.
第一個root爲新的賬號名.
第二個root爲新賬號密碼.
*.*所有數據庫的所有表.
%爲所有ip,此處可指定單個ip.
某個ip用戶例子:

grant select,insert,update,delete,create,drop on test_database.* to baby@123.123.123.123 identified by '123456';

表示:
授予ip爲123.123.123.123的用戶baby分配可對test_database數據庫的所有表進行select,insert,update,delete,create,drop操作的權限,並設定口令爲123.

三.連接mysql.

Mac本可以通過MysqlWorkbench工具進行連接.
輸入賬號root,密碼root即可.
