在采用MySQL作为数据库时候,在JUnit4.4中测试通过,但是今天再次启动发现,启动报如下错误。开发的环境如下:
操作系统:window xp sp3
数据库: Mysql 5.1.39-ndb-7.0.9-cluster-gpl
spring版本:2.5.6
备注:
查看版本为:select version();
授权远程访问用户如下:
创建用户:
create user tbs identified by 123456;
使用Root给tbs用户授权:
grant all priviliges etransmit.* to tbs@'%' identified by '123456';
检查是否为远程访问用户:
use mysql ;
select user,host from user;
如果tbs的host字段为%表示,tbs用户可以从任何主机访问。
访问如下:
Sql代码
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://198.120.3.72:3306/etransmit?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
#jdbc.url=jdbc:mysql://198.120.1.36:3306/etransmit?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
jdbc.username=tbs
jdbc.password=123456
#jdbc.password=root
# Timeto wait for an openconnection before timing out
# (in milliseconds)
jdbc.checkoutTimeout=5000
# Connection pool size
cpool.minPoolSize=10
cpool.maxPoolSize=25
cpool.initialPoolSize
# How long to keep unused connections around(in seconds)
# Note: MySQL times out idle connections after 8 hours(28,800 seconds)
# so ensure this value is below MySQL idle timeout
cpool.maxIdleTime=7200
# Acquiring new connections is slow, so eagerly retrieve extra connections
# whencurrent pool sizeis reached
cpool.acquireIncrement=5
cpool.autoCommitOnClose=true
但是仍然有问题。
报错如下:

通过在C:\WINDOWS\system32\drivers\etc中hosts文件中添加相关的主机ip即可。
错误为
ERROR 1130: Host ’192.168.5.3’ is not allowed to connect to this MySQL server
查过资料后发现这个问题,一般都会遇到,Mysql数据库跟其他数据库不一样,需要设置权限可以控制哪台机器能访问数据库,能访问哪些表。
所以就要登上服务器。
C:\Documents and Settings\Administrator> mysql -h localhost -u root -p
Enter password: ***
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.1.43-community MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
www.2cto.com
mysql> grant all privileges on *.* to 'root'@'%' identified by '123' with grant
-> option;
Query OK, 0 rows affected (0.00 sec)
意思就是将服务器上的所有资源都给root用户权限,%代表来自不同的IP
这里需要注意一下要把密码也要带上。通过密码123登录。
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
最后要刷新下权限。
这样就从本地192.168.5.3这个IP的客户端连接到服务器上了
