CentOs7.3 搭建 Solr单机服务

Solr是一款优秀的基于Lucene的全文检索服务器，它对Lucene进行了扩展，提供了非常丰富的查询语言，并对查询进行了性能优化。Solr和Lucene都由Apache Software Foundation（www.apache.org）管理。

Apache Solr 参考指南

VMware版本号：12.0.0
CentOS版本：CentOS 7.3.1611
Solr 版本：solr-6.6.0
JDK环境：jdk-8u144-linux-x64.tar.gz 具体参考《CentOs7.3 安装 JDK1.8》

关闭防火墙

$ systemctl stop firewalld.service

Solr 安装

下载最新版本的Solr ，我在北京我就选择，清华镜像比较快,文件大概140M

清华镜像:https://mirrors.tuna.tsinghua.edu.cn/apache/lucene/solr/6.6.0/

阿里镜像:https://mirrors.aliyun.com/apache/lucene/solr/6.6.0/

$ cd /opt/
$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/lucene/solr/6.6.0/solr-6.6.0.tgz
$ tar -zxf solr-6.6.0.tgz 
$ cd solr-6.6.0

Solr 操作

$ /opt/solr-6.6.0/bin/solr start -force

响应

Warning: Available entropy is low. As a result,use of the UUIDField,SSL,or any other features that require
RNG might not work properly. To check for the amount of available entropy,use 'cat /proc/sys/kernel/random/entropy_avail'.

NOTE: Please install lsof as this script needs it to deter@L_874_13@ if Solr is listening on port 8983.

Started Solr server on port 8983 (pid=3020). Happy searching!

启动Solr与不同的端口，要更改Solr监听端口，可以-p在启动时使用参数

例如：

$ /opt/solr-6.6.0/bin/solr start -p 8984

浏览器输入 ip:port

http://192.168.252.121:8983/solr/

如果Solr没有运行，您的浏览器会抱怨说它无法连接到服务器。检查您的端口号，然后重试。

如果您不确定Solr是否在本地运行

$ /opt/solr-6.6.0/bin/solr status

响应
