Elasticmate don't run elasticsearch as root.

阅读更多

使用root启动elasticmate的时候会出现:

Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root.

这时你可以创建一个新的用户来启动:

$ adduser test

passwd 123456

Changing password for user test.

New password: 

BAD PASSWORD: The password is shorter than 8 characters

Retype new password: 

 

passwd: all authentication tokens updated successfully.

 

在root用户下为test用户增加权限:chown -R test /opt/app/elasticsearch-2.3.3/

 

切换到test用户:su test

启动elasticmate: ./bin/elasticsearch

抛了一个异常:

Exception in thread "main" java.lang.IllegalStateException: Failed to created node environment

 

Likely root cause: java.nio.file.AccessDeniedException: /data/elasticsearch/gzrs/nodes/1

原因是,在elasticsearch.yml配置文件中path.data是配置在/data/elasticsearch目录下的,没有给test用户分配这个目录的权限。

 

退出test用户:exit

在root用户下为/data/elasticsearch目录授权:chown -R test /data/elasticsearch

 

再使用test用户启动即可。
