elasticsearch 错误：初始堆大小无效

Question

我在linux系统上安装了elasticsearch

elasticsearch-8.13.0-amd64.deb

Debian GNU/Linux 12 (bookworm)

参考文档手动下载并安装Debian包。

然后启动成功。

但是当我修改jvm堆大小时出现错误并且无法启动。

我创建了文件

/etc/elasticsearch/jvm.options.d/jvm.options

，并写道：

-Xms1G 
-Xmx1G

停止并重新启动后：

# sudo systemctl stop elasticsearch.service
# sudo systemctl start elasticsearch.service
# sudo journalctl --no-pager --full --unit elasticsearch

出现以下错误：

我尝试将其设置为

1G

、

2G

、

4G

，但无法正常工作。

只有不设置才能正常启动。

我做错了什么？

Answer 1

最后发现问题是换行格式导致的。

我以前使用Windows系统保存文件。使用

vim

重新保存文件解决了问题。
