Solr的版本一直都在变化(比如之前我在博客园写的关于Linux安装solr，那个solr为7.6版本，此时已经不在了)。
大家可以去这个地址下载对应的版本:http://mirror.bit.edu.cn/apache/lucene/solr/
1.下载solr(我是进入到/usr/local目录下执行这个命令的)
wget http://mirror.bit.edu.cn/apache/lucene/solr/7.7.1/solr-7.7.1.tgz
2.解压
tar -xzvf solr-7.7.1.tgz
3.进入bin目录执行该脚本
cd solr-7.7.1/bin
./install_solr_service.sh ../../solr-7.7.1.tgz
如果没有按照3这样做，就可能出现如下报错:
ERROR: Must specify the path to the Solr installation archive, such as solr-5.0.0.tgz Usage: install_solr_service.sh <path_to_solr_distribution_archive> [OPTIONS] The first argument to the script must be a path to a Solr distribution archive, such as solr-5.0.0.tgz
(only .tgz or .zip are supported formats for the archive) Supported OPTIONS include: -d Directory for live / writable Solr files, such as logs, pid files, and index data; defaults to /var/solr -i Directory to extract the Solr installation archive; defaults to /opt/
The specified path must exist prior to using this script. -p Port Solr should bind to; default is 8983 -s Service name; defaults to solr -u User to own the Solr files and run the Solr process as; defaults to solr
This script will create the specified user account if it does not exist. -f Upgrade Solr. Overwrite symlink and init script of previous installation. -n Do not start Solr service after install, and do not abort on missing Java NOTE: Must be run as the root user
4.成功的标识
接下来就可以通过http://IP地址:8983 访问到solr后台管理界面,如下图所示:
