1. 配置log4j.properties
log4j.rootLogger=INFO,DEBUG,logstash log4j.appender.logstash=org.apache.log4j.net.SocketAppender log4j.appender.logstash.Port=4560 log4j.appender.logstash.RemoteHost=10.0.0.5 log4j.appender.logstash.ReconnetionDelay=60000 log4j.appender.logstash.LocationInfo=true
2. 修改logstash input组件(favblog-log4j.conf)，将日志输出到Elasticsearch
input{
log4j{
host => "10.0.0.5"
mode => "server"
type => "log4j-json"
port => 4560
}
}
output{
stdout{ codec => rubydebug }
elasticsearch { hosts => ["10.0.0.5:9200"] }
}
3.启动Logstash
[[email protected] bin]# ./logstash -f favblog-log4j.conf
Settings: Default pipeline workers: 4
log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAuthCache).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

4. 查询Log4j输出日志
http://10.0.0.5:9200/logstash-2016.05.31/_search?q=*&pretty%27
在elasticsearch中查询到输出的log4j日志。
