Connecting to the MySQL Server

客戶端程式連線MySql服務

1. 不指定連線引數

因為沒有指定引數，將使用預設值
語法：shell> mysql
預設主機名為：localhost
[root@root ~]# mysql

shell> mysql -h localhost -u myname -p mydb

[root@qingmeng001 ~]# mysql --host=localhost --user=chenwx --password mysql

4.指定IP和協議

語法：

5. 配置ipv6

--host=::1.

6. 使用TCP/IP連線到遠端伺服器

語法：
shell> mysql --host=remote.example.com
預設埠：3306

7.指定埠選項--port -P

語法：
shell> mysql --host=remote.example.com --port=13306

8. windows使用named-pipe連線
