我尝试安装插件一行写这行
sudo -u logstash /urs/share/logstash/bin/logstash-plugin install logstash-filter-geoip
就像在这个tuto中一样 https://www.elastic.co/webinars/getting-started-logstash?baymax=default&elektra=docs&storm=top-video
我也是这样尝试
sudo ./logstash-plugin install logstash-filter-geoip
我的java版本是9，而我的/etc/environment a只有我的java_home变量
JAVA_HOME="/usr/lib/jvm/java-9-oracle/bin/java"
JAVACMD=/usr/bin/java
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
我尝试将此变量放在我的.bashrc中，但无效
我的服务器版本是ubuntu 16.04
我要将我的java版本改为8但没有改变
