kibana启动报错EACCES: permission denied, open '/usr/local/kibana/optimize/.babelcache.json'

错误信息：

  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

问题原因：

EACCES: permission denied, open '/usr/local/kibana/optimize/.babelcache.json'

所以要检查你启动kibana的用户是否有此文件夹的权限，切换一个用户，或者赋予权限（chown -R esuser:esgroup kibana）即可解决
