Question

尝试在ubuntu 14.04中将logsatash添加到upstart。脚本非常简单：

  # logstash - agent instance
  description     "logstash"

  start on virtual-filesystems
  stop on runlevel [06]

  limit nofile 65550 65550

  script
     /usr/bin/java -jar /home/user/logstash/logstash-1.2.1-flatjar.jar agent -f /home/user/logstash/logstash.config -l /home/user/logstash/new1.log -v
  end script

命令本身（脚本节中的行）在从shell运行时启动logstash，但在启动时使用：

start logsatsh

logstash启动。但几分钟后它停止，服务状态为:(使用状态命令）

logstash stop/waiting

logstash文件配置文件：

input {


     stdin{}
        file{
                path => "/home/user/log/logstash-1.4.0/mylog.log"
        }
         udp {
                codec => json
                host => "0.0.0.0" # string (optional), default: "0.0.0.0"
                #message_format => ... # string (optional)
                port =>  9998
                #tags => ... # array (optional)
                type => "log4j" # string (required)
       }
        tcp{
                port => 9998
                type => "log4j"
                codec => json
        }
}

output {
  stdout{}
  elasticsearch { host => localhost }
}

logstash进程没有执行fork（使用strace测试）。尝试将命令部分更改为'exec'但没有成功。任何的想法？

我建议您在elasticsearch debs上查找upstart logstash.conf，这是你可能想看的部分：

console none
script
  # Defaults
  PATH=/bin:/usr/bin
  LS_HOME=/var/lib/logstash
  LS_HEAP_SIZE="500m"
  LS_JAVA_OPTS="-Djava.io.tmpdir=${LS_HOME}"
  LS_LOG_FILE=/var/log/logstash/logstash.log
  LS_USE_GC_LOGGING=""
  LS_CONF_DIR=/etc/logstash/conf.d
  LS_OPEN_FILES=16384
  LS_NICE=19
  LS_OPTS=""

  # Override our defaults with user defaults:
  [ -f /etc/default/logstash ] && . /etc/default/logstash

  HOME="${HOME:-$LS_HOME}"
  JAVA_OPTS="${LS_JAVA_OPTS}"
  # Reset filehandle limit
  ulimit -n ${LS_OPEN_FILES}
  cd "${LS_HOME}"

  # Export variables
  export PATH HOME JAVA_OPTS LS_HEAP_SIZE LS_JAVA_OPTS LS_USE_GC_LOGGING
  test -n "${JAVACMD}" && export JAVACMD

  exec nice -n ${LS_NICE} /opt/logstash/bin/logstash agent -f "${LS_CONF_DIR}" -l "${LS_LOG_FILE}" ${LS_OPTS}
end script
