Fiware 天鹅座没有'；更新数据库

我想订阅Orion向Cygnus发送通知。然后cygnus将所有数据保存在mysql数据库中。我使用这个脚本订阅car1的speed属性

有关我的cygnus服务和cygnus配置的一些信息（

systemctl status cygnus

）：

agent_mysql.conf：

# main configuration
cygnusagent.sources = http-source
cygnusagent.sinks = mysql-sink
cygnusagent.channels = mysql-channel

# source configuration
cygnusagent.sources.http-source.channels = mysql-channel
cygnusagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
cygnusagent.sources.http-source.port = 5050
cygnusagent.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.OrionRestHandler

# url target
cygnusagent.sources.http-source.handler.notification_target = /notify
cygnusagent.sources.http-source.handler.default_service = def_serv
cygnusagent.sources.http-source.handler.default_service_path = def_servpath
cygnusagent.sources.http-source.handler.events_ttl = 10
cygnusagent.sources.http-source.interceptors = ts gi
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf


#Orion MysqlSink Configuration
cygnusagent.sinks.mysql-sink.channel = mysql-channel
cygnusagent.sinks.mysql-sink.type = com.telefonica.iot.cygnus.sinks.OrionMySQLSink
cygnusagent.sinks.mysql-sink.enable_grouping = false
# mysqldb ip
cygnusagent.sinks.mysql-sink.mysql_host = 127.0.0.1
# mysqldb port
cygnusagent.sinks.mysql-sink.mysql_port = 3306
cygnusagent.sinks.mysql-sink.mysql_username = root
cygnusagent.sinks.mysql-sink.mysql_password = 12345
cygnusagent.sinks.mysql-sink.attr_persistence = column
cygnusagent.sinks.mysql-sink.table_type = table-by-destination

# configuracao do canal mysql
cygnusagent.channels.mysql-channel.type = memory
cygnusagent.channels.mysql-channel.capacity = 1000
cygnusagent.channels.mysql-channel.transactionCapacity = 100

在阅读了问题之后，我在这行中更改了我的agent_mysql.conf：

cygnusagent.sinks.mysql-sink.attr_persistence=column

到

cygnusagent.sinks.mysql-sink.attr_persistence=row

并重新启动服务。然后我更新了orion实体，查询了数据库，什么也没发生

天鹅座日志文件：

---

注意：我的JAVA_主页已设置。

正如您在发布的日志中所看到的，Cygnus日志文件存在问题：

java.io.FileNotFoundException: ./logs/cygnus.log (No such file or directory)

之后，天鹅座停了下来。您必须检查关于log4j的配置，所有内容都位于

/usr/cygnus/conf/log4j.properties

（它应该存在，它是由RPM创建的……如果不存在，因为它是从源代码而不是RPM创建的，它必须从可用的模板创建）。另外，您可以发布实例配置文件吗？不管怎样，你正在运行哪个版本

编辑1

最近，我们发现另一个用户处理相同的错误，问题是

/usr/cygnus/conf/log4j的内容

flume.root.logger=INFO,LOGFILE
flume.log.dir=./log
flume.log.file=flume.log

而不是模板包含的内容：

flume.root.logger=INFO,LOGFILE
flume.log.dir=/var/log/cygnus/
flume.log.file=flume.log

一旦更改，它就工作了，因为RPM创建的是
/var/log/cygnus
，而不是
/log
您的配置似乎正常。你能分享一下天鹅座跑步的全部记录吗？请使用gist或pastebin。关于attr_持久性，正如您在链接问题中已经注意到的，如果您将其配置为“column”，那么Cygnus将不会创建表，但它必须由您设置。相反，如果使用“行”，它是由天鹅座自动创建的。@frb我更新了问题。
flume.root.logger=INFO,LOGFILE
flume.log.dir=./log
flume.log.file=flume.log

flume.root.logger=INFO,LOGFILE
flume.log.dir=/var/log/cygnus/
flume.log.file=flume.log
