Question

给出的debian软件包在我的ubuntu64虚拟机上安装了Elastic Search V5.0

正如教程sudo -i service elasticsearch start中所解释的那样，不会在此处给出任何消息（设计不佳）

我尝试将STDOUT.log文件添加到目录中，并在启动弹性搜索后仍然为空

如果我sudo bin/elasticsearch我得到了这个痕迹：

Exception in thread "main" ElasticsearchParseException[malformed, expected settings to start with 'object', instead was [VALUE_STRING]]

没有sudo provlidges：

我不喜欢在stackoverflow上发布这么多文本，但这里的配置位于：/etc/elasticsearch

# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
cluster.name: sdc-test-es-cluster
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
#
# ---------------------------------- Various -----------------------------------
#
# Disable starting multiple nodes on a single system:
#
#node.max_local_storage_nodes: 1
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true

问题在于错误配置的Elasticsearch。

确保ES使用来自正确位置的配置文件。例如，＆＃34;没有sudo特权＆＃34;输出错误的位置。
确保您在配置中没有错误。

要隔离问题，请在配置中注释掉所有内容，然后逐行取消注释配置中的自定义设置，并尝试启动。如果找到导致问题的行，请检查文档。

另外，尝试不用＆＃34; -d＆＃34;选项，Elasticsearch将在控制台中输出完整的堆栈跟踪，它应该告诉更多有关配置错误的设置。

什么会导致Elastic Search不生成日志文件？
