[英]logstash can't find jdk
我想開始使用logstash和彈性搜索。 我遵循了Elastic的文檔
https://www.elastic.co/guide/zh-CN/logstash/current/getting-started-with-logstash.html
我想從第一個演示命令開始。我在Windows 10 64位上工作。 因此,我下載了logstash.zip,打開了cmd並移至
C:\\ Program Files \\ Logstash \\ logstash-6.3.1 \\ bin>
夾。 之后我進入
logstash -e'輸入{stdin {}}輸出{stdout {}}'
然后我得到一個錯誤
找不到或加載Files \\ Java \\ jdk1.8.0_144 \\ bin。 (對不起,我用德語開發,但我不知道英語錯誤消息)
我在這台電腦和命令上運行eclipse和Java

Java版本
輸出
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
所以我想應該沒問題。 誰能幫我為什么logstash找不到它? 我需要設置一些額外的東西嗎? 在Systemvariables中,將jdk和jre設置為“ Path”變量,並在“用戶變量”中創建了JAVA_HOME變量。 提前致謝
看起來您的JAVA_HOME和PATH搞砸了。 一定是這樣的
JAVA_HOME = C:\Program Files\Java\jdk1.7.0_25
PATH = C:\Program Files\Java\jdk1.7.0_25\bin
要進行交叉檢查,您可以在終端中嘗試
echo %JAVA_HOME%
和
javac -version
檢查類PATH變量。
您可以參考此鏈接來逐步設置變量。
