#############sample mysql sample 導入和導出
############mysql 導入導出
CREATE DATABASE `db_monitor` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
賦予資料庫(zqxt)權限給某使用者,可以是已經存在的使用者或新使用者名
GRANT ALL PRIVILEGES ON zqxt.* TO "任意使用者名"@"localhost" IDENTIFIED BY "新密碼";
重新整理權限
FLUSH PRIVILEGES;
退出資料庫shell
EXIT;
1.備份單個資料庫的資料和結構(,資料庫名mydb)
mysqldump -uroot-p123456 db_monitor>c:\db_monitor.sql
2.還原單個資料庫(需指定資料庫)
(1) mysql>use mydb
mysql>source f:\mydb.sql
(2) mysql -uroot -p123456 mydb <c:\db_monitor.sql
# 輸入密碼開始導入資料
#######command
https://dev.mysql.com/doc/refman/8.0/en/testing-server.html
If you specify a database name, mysqlshow displays a list of the tables within the database:
shell> bin/mysql -e "SELECT User, Host, plugin FROM mysql.user" mysql
shell> bin/mysqlshow mysql
Use mysqladmin to verify that the server is running. The following commands provide simple tests to check whether the server is up and responding to connections:
shell> bin/mysqladmin version
shell> bin/mysqladmin variables
###############phpadmin連接配接遠端資料庫
phpadmin連接配接遠端資料庫
1、打開wampserver下phpmyadmin的目錄在D:\wamp\apps\下 D:\wamp\apps\phpmyadmin4.1.14
2、找到config.inc.php檔案,打開修改要連接配接的遠端MySQL的host,user和password,更改這3個資訊即可
其中必須保證資料庫有被遠端連接配接的權限
/* Authentication type */
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'admin';
$cfg['Servers'][$i]['password'] = 'root';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '192.168.1.154';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
3.如果要用root登入此時也應該把host修改為localhost;
