使用自制软件升级 Elasticsearch 7.3

Question

我通过自制软件使用 Elasticsearch 6.8，并尝试升级到 7.3。以前，在 6.8 上，我已经收到有关不存在的日志文件的警告，但服务器仍会运行 - 所以我什么也没做。

现在使用 7.3，出现错误并且服务器无法运行：

Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]
output:
[0.002s][error][logging] Error opening log file 'logs/gc.log': No such file or directory
[0.002s][error][logging] Initialization of output 'file=logs/gc.log' using options 'filecount=32,filesize=64m' failed.
error:

Invalid -Xlog option '-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m', see error log for details.

我尝试创建安装了 elasticsearch 的目录/文件，但这对我不起作用（或者我做错了什么）。

参考：https : //onecompiler.com/questions/3uwszcf3x/homebrew-installed-elasticsearch-failing-to-start

我通过将相对日志/gc.log 路径更改为绝对路径来解决此问题。请按照以下步骤解决问题

1. 打开位于 /usr/local/etc/elasticsearch/jvm.options 的 jvm.options 文件

2. 将相对路径从以下更改为绝对路径

# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m

到

# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=/usr/local/var/log/elasticsearch/gc.log:utctime,pid,tags:filecount=32,filesize=64m

3. 重新启动 elasticsearch$ brew services restart elasticsearch-full或直接在没有守护进程的情况下启动它 -$ elasticsearch
