小編給大家分享一下如何解決Docker容器中運行flume及啟動不輸出運行日志的問題，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
flume配置文件如下：
# Name the components on this agent app1.sources = r1 app1.sinks = k1 app1.channels = c1 # Describe/configure the source app1.sources.r1.type = avro app1.sources.r1.bind = 0.0.0.0 app1.sources.r1.port = 44444 # Describe the sink #a1.sinks.k1.type = logger app1.sinks.k1.type = file_roll app1.sinks.k1.sink.directory = /var/log/my/app1 app1.sinks.k1.sink.rollInterval=86400 app1.sinks.k1.sink.batchSize=100 app1.sinks.k1.sink.serializer=text app1.sinks.k1.sink.serializer.appendNewline = false # Use a channel which buffers events in memory app1.channels.c1.type = memory app1.channels.c1.capacity = 1000 app1.channels.c1.transactionCapacity = 100 app1.channels.c1.byteCapacity = 100000000 app1.channels.c1.byteCapacityBufferPercentage = 10 # Bind the source and sink to the channel app1.sources.r1.channels = c1 app1.sinks.k1.channel = c1 # Name the components on this agent app2.sources = r2 app2.sinks = k2 app2.channels = c2 # Describe/configure the source app2.sources.r2.type = avro app2.sources.r2.bind = 0.0.0.0 app2.sources.r2.port = 44445 # Describe the sink #a1.sinks.k1.type = logger app2.sinks.k2.type = file_roll app2.sinks.k2.sink.directory = /var/log/my/app2 app2.sinks.k2.sink.rollInterval=86400 app2.sinks.k2.sink.batchSize=100 app2.sinks.k2.sink.serializer=text app2.sinks.k2.sink.serializer.appendNewline = false # Use a channel which buffers events in memory app2.channels.c2.type = memory app2.channels.c2.capacity = 1000 app2.channels.c2.transactionCapacity = 100 app2.channels.c2.byteCapacity = 100000000 app2.channels.c2.byteCapacityBufferPercentage = 10 # Bind the source and sink to the channel app2.sources.r2.channels = c2 app2.sinks.k2.channel = c2
dockerfile如下：

下面看下flume 啟動不輸出運行日志
問題
以前碰到的一個問題，算是一個小問題，flume 用命令
./flume-ng agent -c /opt/apps/flume/conf -f /opt/apps/flume/conf/syslog_tcp.conf -n a1 -Dflume.root.logger=INFO,console
啟動的時候，flume使用的log4j不起效，不會輸出日志到日志文件。
解決
在啟動時去掉
-Dflume.root.logger=INFO,console
這個命令就好了。flume的log4j就正常工作了。也算是一個坑。
加上這個命令會將運行的日志在控制臺輸出。
