Docker容器中运行flume及启动不输出运行日志问题

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：

from ubuntu:16.04

run apt-get update 
add jdk-8u77-linux-x64.tar.gz /usr/local/java 
run cp /etc/profile /etc/profile.bak

下面看下flume 启动不输出运行日志

问题

以前碰到的一个问题，算是一个小问题，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

启动的时候，flume使用的log4j不起效，不会输出日志到日志文件。

解决

在启动时去掉

-dflume.root.logger=info,console

这个命令就好了。flume的log4j就正常工作了。也算是一个坑。

加上这个命令会将运行的日志在控制台输出。

总结

以上所述是小编给大家介绍的 docker容器中运行flume及启动不输出运行日志问题，希望对大家有所帮助
