这里是用的Mysql的分支版本MariaDB,除了安装的包不同外,操作基本相同。
本人用的是Archlinux,也只是安装软件的方式不同。
一、MariaDB
- 安装MariaDB(参见ArchWiki)
+ [安装](https://wiki.archlinux.org/index.php/Pacman)位于[官方软件源](https://wiki.archlinux.org/index.php/Official_repositories)的[mariadb](https://www.archlinux.org/packages/?name=mariadb)、[libmariadbclient](https://www.archlinux.org/packages/?name=libmariadbclient) 和 [mariadb-clients](https://www.archlinux.org/packages/?name=mariadb-clients)
+ 运行:
# mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
+ 启动 mysqld[守护进程](https://wiki.archlinux.org/index.php/Daemon),运行安装脚本,然后重新启动守护进程:(按提示设置MariaDB用户名和密码)
# systemctl start mysqld
# mysql_secure_installation
# systemctl restart mysqld
- 启动、登录,建立数据库
- 启动:
# systemctl start mysqld
- 登录:(这里是用的root用户,可以把root换为自己的用户名)
$ mysql -p -u root
- 创建测试用的数据库(登录后)
MariaDB [(none)]> create database test;
二、eclipse建立测试项目
用户名和密码设为自己的。
package test;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
public class MariaDB {
// The JDBC Connector Class.
private static final String dbClassName = "org.mariadb.jdbc.Driver";
// Connection string. emotherearth is the database the program
// is connecting to. You can include user and password after this
// by adding (say) ?user=paulr&password=paulr. Not recommended!
private static final String CONNECTION =
"jdbc:mariadb://localhost:3306/emotherearth";
public static void main(String[] args) throws
ClassNotFoundException,SQLException
{
System.out.println(dbClassName);
// Class.forName(xxx) loads the jdbc classes and
// creates a drivermanager class factory
Class.forName(dbClassName);
// Properties for user and password. Here the user and password are both 'paulr'
Properties p = new Properties();
p.put("user","root");
p.put("password","123456");
// Now try to connect
Connection c = DriverManager.getConnection(CONNECTION,p);
System.out.println("It works !");
c.close();
}
}
二、jdbc连接器
方法一:
- 下载 Mariadb-Java-Client (https://mariadb.com/my_portal/download/java-client)
-
直接把jar包导入到项目中,或导入到系统java库中
右击“项目”→选择Properties,在弹出的对话框左侧列表中选择Java Build Path,如下图所示:选择Add External JARs。
eclipse导入包
方法二: 安装包 mariadb-jdbcAUR
$ yaourt mariadb-jdbc
要确保项目里有了Mariadb-Java-Client.jar
三、运行测试
此时运行测试程序,得到:
org.mariadb.jdbc.Driver
It works !
