在国产处理器服务器上搭建mysql(MariaDB)+jsp(java)开发平台。(基于海之舟1.0A操作系统）

1.mysql设置
对于海之舟1.0A操作系统，mysql、java、tomcat已预装，在/etc/rc.local中设定开机启动即可。
su root
nano /etc/mysql/mariadb.conf.d/50-server.cnf
#bind-address = 127.0.0.1 //注释这行,关闭ip限制.
mysql -v //进入数据库

use mysql;
CREATE DATABASE db1;
SHOW DATABASES;
grant all on . to zs1@’%’ identified by ‘1234’;
show grants for zs@’%’;
use db1;
CREATE TABLE t1(bid int(20) not null auto_increment primary key, id int(100),xm varchar(20),zh varchar(100),uploadTime varchar(100));
SHOW TABLES;
DESCRIBE t2; //查看表t2的结构
insert into t1(id,xm,zh) values (20,“zhangs”,“myzh”);
2.jsp
su zs
cd /home/zs/apache-tomcat-8.5.35/webapps/ROOT
nano m1.jsp //已预置的范例代码
