启动 elasticsearch-2.0 时遇到问题

Question

我最近运行遇到无法启动 elasticsearch 的问题。

版本 2.0 OS: Linux

显示错误消息

如何启动elasticsearch？

编辑 01：

我已将分片和副本放入 elasticsearch.yml 文件中，但仍然无法启动 elasticsearch。得到上面的错误信息。

编辑 02：

我已将分片添加到 yml 文件中。

# You can set a number of options (such as shard/replica options, mapping
# or analyzer definitions, translog settings, ...) for indices globally,
# in this file.
#
# Note, that it makes more sense to configure index settings specifically for
# a certain index, either when creating it or by using the index templates API.
#
# See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html>
# for more information.

# Set the number of shards (splits) of an index (5 by default):
#
index.number_of_shards: 2

# Set the number of replicas (additional copies) of an index (1 by default):
#
index.number_of_replicas: 1

我们继续将服务器恢复到之前 elasticsearch 正常运行的日期，问题已解决。
