自動啟動

給建立的腳本設定可執行權限

編輯

/etc/rc.d/rc.local

檔案

在最後增加一行

/bin/sh /opt/flume-1.8.0/start.sh
           

開機重新開機後，發現并沒有

flume

的程序

檢視系統日志

/var/log/message

發現如下，但是系統環境變量裡肯定是填了

JAVA_HOME

的，如果沒填，直接啟動

flume

程式也是失敗的

Aug  9 01:47:01 manager rc.local: ready to start flume-agent a1 for minute...
Aug  9 01:47:01 manager rc.local: Warning: JAVA_HOME is not set!
Aug  9 01:47:01 manager rc.local: Error: Unable to find java executable. Is it in your PATH?
Aug  9 01:47:02 manager rc.local: ready to start flume-agent a2 for 15min...
Aug  9 01:47:02 manager rc.local: Warning: JAVA_HOME is not set!
Aug  9 01:47:02 manager rc.local: Error: Unable to find java executable. Is it in your PATH?
Aug  9 01:47:03 manager rc.local: ready to start flume-agent a3 for hour...
           

解決辦法是進入

flume

安裝目錄下

conf

檔案夾

複制一個

flume-env.sh

檔案

修改内容，填上

JAVA_HOME

(根據自己的填寫)

export JAVA_HOME=/opt/java-1.8.0_121
           

儲存退後，再重新開機可以驗證

flume-agent

自啟動成功。
