Solr配置

Question

我尝试使用以下方法安装Solr:

java -jar start.jar

但是我下载了源代码并没有编译它(没注意).错误是:

http://localhost:8983/solr/admin/

HTTP ERROR: 404
Problem accessing /solr/admin/. Reason:
NOT_FOUND 

然后我下载了solr的编译版本,但在尝试运行示例配置时,我得到了异常:

java.net.BindException: Address already in use 

有没有办法恢复solr配置并从头开始？看起来配置搞砸了.我手册中没有看到任何与之相关的内容.

这是错误:

Answer 1

这意味着您已经在该特定端口上运行了应用程序.

跑:

$ lsof -i :8983

这将为您提供在该端口上运行的任何应用程序的列表.就我而言,Solr已经在运行,我回来了:

COMMAND   PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    10289 patricia  111u  IPv6 399410      0t0  TCP *:8983 (LISTEN)

通过填写PID来杀死这个过程:

$ kill 10289

然后尝试再次运行Solr.

Answer 2

这java.net.BindException意味着您尝试solr在早期实例继续运行时重新启动,或者更少可能是您在端口8983上运行了其他东西.您应该找到该进程,将其删除,然后重新开始solr.

Answer 3

它绑定到其他一些应用程序.如果它是一个重要的应用程序,您可以使用以下更改jetty默认端口:

java -Djetty.port=8181 -jar start.jar
