Refer to the log for complete error details.

sudo启动报错:
[root@i-j73a8nn6 ~]# sudo elasticsearch-2.2.1/bin/elasticsearch

首先不能用root用户登陆,sudo默认就是root用户,sudo时需要指定其他用户名。例如:sudo -iu user_a bin/elasticsearch

新增了一个用户,让后在以新增用户启动完成。
不知道各路大神有没有在root下启动的方法?

vi /etc/sysconfig/elasticsearch
将 JAVA_HOME=/root/jdk1.8.0_60 写到文件中保存后启动
service elasticsearch start
正在启动 elasticsearch: [确定]

我的Logstash是2.2.2版本,系统环境是ubuntu kylin 16,然后从[官网]下载的logstash_2.2.2-1_all.deb文件进行安装的,使用的是普通用户,执行sudo service logstash configtest时,提示如下:

Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME.

安装@geekfranca 说的方法,修改了/etc/init.d/logstash 文件,执行成功了,道理应该都是一样的
