Debian-Solr无法启动，日志文件被删除 [英] Debian - Solr doesn't start and log file is getting deleted
问题描述
我刚刚从 http://www.eu.apache.org/dist/lucene/solr/5.3.1/solr-5.3.1.tgz
然后我用tar zxvf solr-5.3.1.tgz解压缩它，并使用cd/solr-5.3.1/bin将其移到/bin/目录中，以使用以下命令启动二进制文件
Then I unpacked it with tar zxvf solr-5.3.1.tgz moved into the /bin/ directory with cd /solr-5.3.1/bin to start the binary with
./solr start
根据教程和自述文件，首次试用不需要更多.
According to tutorials and readme more is not needed for a first trial run.
等待30秒才能看到Solr在端口8983上运行
Waiting up to 30 seconds to see Solr running on port 8983
[-] 30秒后仍看不到Solr在8983上收听！
[-] Still not seeing Solr listening on 8983 after 30 seconds!
tail:无法打开"/var/solr/logs/solr.log"
tail: „/var/solr/logs/solr.log" cannot be opened for reading
因此，我创建了目录和solr.log文件，并使用
So I created the directory and the solr.log file and restarted it with
./solr start
solr会自动删除日志文件，并且错误相同，即该日志文件不可读.这是一个有趣的循环.如何找到一种读取日志文件的方法，以了解为什么solr无法启动?
The log file is automatically deleted by solr and the error is the same, that the log file is not readable. This is a funny loop. How can I find a way to read the log file to understand why solr is not starting?
java -version

推荐答案
我不认为日志文件会被删除-可能从未创建过. Solr和Lucene 5.3需要Java 7，因此，如果Java6 VM是用于启动Solr的JVM，它将失败.
I don't think the log file is being deleted - it's probably just never created. Solr and Lucene 5.3 require Java 7, so if the Java6 VM is the JVM used for starting Solr - it's going to fail.
您可以使用./solr start -f使Solr在前台运行以捕获任何错误，但是如果日志记录子系统从未启动，则可能效果不佳.
You can use ./solr start -f to get Solr to run in the foreground to catch any errors, but if the logging sub system never starts, it might not do much good.
