mysql远程授权

2014-2-14 16:00 |个人分类:技术细节| mysql, 配置

1 通过phpmyadmin添加一个新用户

用户	主机	密码	全局权限	授权	操作

root

是

ALL PRIVILEGES

是

编辑权限

导出

2 修改 vi /etc/mysql/my.cnf 中 #bind-address = 127.0.0.1 注销

3 重启 /etc/init.d/mysql restart

jbpm designer使用注意

写完流程，要点击png生成图片否则后面404
如果从其他地发导入流程则packagename is not valid。因为你自己写的包名和xml或json中也带有的包名不一致。改成一致的（两处：注1,注2）
Steps to Reproduce:
1. Create new package "pkg1"
2. Create new BPMN2 process in package "pkg1"
3. Import BPMN2 process into asset. It is attached.
4. Click on view PNG
5. Validate
可发布的流程在资产中显示为一个绿色的对号
注1 jbpm2
<bpmn2:process id="aaa.jiandan" drools:packageName="aaa" name="jiandan" isExecutable="true">
注2 json：
{"executable":true,"package":"aaa","vardefs":"","adhocprocess":"false","imports":"","globals":"","id":"aaa.jiandan","version":"","timeunit":"s","currency":"","targetnamespace":"http://

aaa为包名，jiandan为流程名称

core模块有时启动正常，有时不能启动，报错 17:51:22,631 ERROR [org.springframework.web.context.ContextLoader] (MSC service thread 1-5) Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'koalaBPMSession' defined in class path resource [META-INF/spring/jbpm-spring.xml]: Invocation of init method failed; nested exception is java.lang.Exception: ProcessLoadError: unable to parse xml : Exception class java.lang.NullPointerException : null

可能是由于错误流程造成的，删除数据库或者跟新源码试试

5 jbpm designer 在tomcat下编辑后保存再次打开报错。重启tomcat就好

可能是某个部件没有名字（特别是分支线上没有名字）

7 KoalaProcessInfo 表删除解决core启动失败（就不用删除整个数据库了）
