Question

我手动安装了Elasticsearch 5.2.1 RPM。我已经配置了我在之前版本中使用的基本网络设置。当我尝试启动Elasticsearch时，它给我一些错误。我的旧版本2.3.1中运行的设置相同，没有任何问题。我不确定是否需要为此添加任何其他设置。

我的配置

cluster.name: ddlm.cluster

node.name: dd.sys.node-1

path.data: /ddlm/es/data/

path.logs: /ddlm/logs/elasticsearch_logs

bootstrap.memory_lock: true

Answer 1

当我更改此文件/etc/security/limits.conf中的设置时，我的问题得到了解决。我们需要在该文件中添加这两行

<<username>> soft memlock unlimited
<<username>> hard memlock unlimited

添加此行后，您可以启用bootstrap.memory_lock: true

Answer 2

我也有这个问题，我使用tmux，有时在tmux中你的配置执行不正确，所以你应该重新启动计算机或从tmux运行elasticsearch。

Elasticsearch无法从基本网络设置开始5.2.1
