我无法在这些文件中找到任何错误或警告。你知道什么地方可能有问题吗？或者我可以在哪里找到更多的线索

更新：

以下是/etc/elasticsearch/elasticsearch.yml文件：

#
# 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: 0.0.0.0
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#

ES仍未能启动

谢谢。

由于没有错误消息，很难找到确切的原因，但是你能提供你的

elasticsearch.yml

吗？我还看到你已经定义了

1gb

的堆空间，你能试着增加它吗

日志中唯一有趣的是：

活动：自美国东部夏令时2020-09-16 16:22:32周三起失败（结果：超时）； 3分钟23秒前文件：进程：1716 ExecStart=/usr/share/elasticsearch/bin/systemd entrypoint-p ${PID_DIR}/elasticsearch.PID--安静（代码=退出，状态=143）Main PID:1716（代码=退出，状态=143）

您可以注意到

超时

和

143状态

，您可以在

并查看是否可以找出错误日志或更多信息来调试问题。

您是否查看了

/var/log/messages

中是否有任何内容？是的，包含日志。谢谢，谢谢。我将堆大小增加到4G，但仍然没有乐趣。我添加了elasticsearch.yml文件以供参考。
