mysql创建数据库命令、导入sql命令、导出数据库命令

1、在登录到服务器后,操作mysql数据库,按照如下步骤创建数据库,并导入sql文件(记得改为自己实际的sql文件路径)
我这里是进入到/usr/local/mysql/bin目录下进行登录mysql,也可以根据自己实际情况登录mysql,比如:mysql -uroot -p

[root@vultr bin]# ./mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

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

mysql> CREATE DATABASE wgcloud DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.01 sec)

mysql> use wgcloud;
Database changed
mysql> source /wgcloudTest/wgcloud-MySQL_v3.3.7.sql;
Query OK, 0 rows affected (0.01 sec)

Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> 

	
看到都是Query OK,就是导入完成了
2、如果我们要备份数据库的话,使用mysql提供的导出工具mysqldump即可,如下进入到mysql安装目录bin下操作

[root@vultr bin]# ./mysqldump -uroot -p wgcloud > /home/wgcloud.sql
