centos - elasticsearch which: no java in (/sbin:/bin:/usr/sbin:/usr/bin)

Question

机器：centos7.2

javahome：
export JAVA_HOME=/root/jdk1.8.0_60
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

[root@i-j73a8nn6 ~]# java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

[root@i-j73a8nn6 ~]# $PATH
-bash: /root/jdk1.8.0_60/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin: No such file or directory

如果不是sudo启动时报错：
[root@i-j73a8nn6 ~]# elasticsearch-2.2.1/bin/elasticsearch
Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root.

at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144)
at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:285)
at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)

Refer to the log for complete error details.

sudo启动报错：
[root@i-j73a8nn6 ~]# sudo elasticsearch-2.2.1/bin/elasticsearch
which: no java in (/sbin:/bin:/usr/sbin:/usr/bin)
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME

Answer 1

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

Answer 2

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？

Answer 3

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]

Answer 4

3楼正解，我以root用户启动了

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
