Question

如果他们在Mac上遇到此问题，我希望能帮助他人。我最近使用Homebrew将ES更新为2.2.x分支：

brew uninstall --force elasticsearch
brew update
brew install elasticsearch

我在端口9200上尝试同时尝试localhost和127.0.0.1时出现连接错误。

curl http://localhost:9200
curl: (7) Failed to connect to localhost port 9200: Connection refused

我尝试卸载并加载。

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.elasticsearch.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.elasticsearch.plist

然后尝试手动启动。

elasticsearch

出现以下错误，表明Java版本1.7.x是一个错误，以及它无法启动的原因。

Exception in thread "main" java.lang.RuntimeException: Java version: Oracle Corporation 1.7.0_45 [Java HotSpot(TM) 64-Bit Server VM 24.45-b08] suffers from critical bug https://bugs.openjdk.java.net/browse/JDK-8024830 which can cause data corruption.
Please upgrade the JVM, see http://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html for current recommendations.
If you absolutely cannot upgrade, please add -XX:-UseSuperWord to the JAVA_OPTS environment variable.
Upgrading is preferred, this workaround will result in degraded performance.

在收到此错误后，1.7.x分支上的先前安装的插件也出现了错误。

Answer 1

我发现的这些问题的解决方案如下：

编辑/usr/local/etc/elasticsearch/elasticsearch.yml文件并验证bind_host配置是否已注释，因此默认为0.0.0.0。
修改/usr/local/Cellar/elasticsearch/YOUR_VERSION/libexec/bin/elasticsearch.in.sh文件并在另一个-XX:-UserSuperWord之后添加JAVA_OPTS标记：

JAVA_OPTS="$JAVA_OPTS -XX:-UseSuperWord"
手动删除以前的插件，以便为该ES分支安装最新版本：

/usr/local/Cellar/elasticsearch/2.2.0_1/libexec/bin/plugin list

Installed plugins in /usr/local/var/lib/elasticsearch/plugins:
```
- bigdesk
- head
```
/usr/local/Cellar/elasticsearch/2.2.0_1/libexec/bin/plugin remove bigdesk /usr/local/Cellar/elasticsearch/2.2.0_1/libexec/bin/plugin remove head

完成这些步骤后，我可以再次启动ES 2.x然后我可以重新安装任何所需的插件。我希望如果他们遇到类似的问题，这会有所帮助。

Answer 2

在MacO上遇到此问题，当时我尝试使用homebrew卸载elasticsearch7并安装elastisearch @ 6。我通过手动删除以下目录并安装elasticsearch @ 6

解决了该问题

Data:    /usr/local/var/lib/elasticsearch/
Logs:    /usr/local/var/log/elasticsearch/elasticsearch_<<user>>.log
Plugins: /usr/local/var/elasticsearch/plugins/
Config:  /usr/local/etc/elasticsearch/

步骤：

>brew uninstall elasticsearch
>rm -rf <<above mentioned directories>>
>brew install elasticsearch@6

Elasticsearch无法在OSX上启动或运行
