我最近遇到了一个问题，我无法启动elasticsearch。

2.0版操作系统: Linux

显示了一个错误消息。

如何启动弹性搜索？

编辑01：

我已经将碎片和副本放在elasticsearch.yml文件中，但仍然无法启动elasticsearch。获取上述错误消息。

编辑02：

我已将碎片添加到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elasticsearch工作的前一天，问题就解决了。
