前言
網上搜索了幾天，發現文章都比較舊了，現在更新下。 要解決的問題爲安裝Redmine_dmsf插件後，配置插件時有如下警告“Xapian not available”，且“Index database"不可以編緝。
環境
- Ubuntu 20.04.2LTS server
- Ruby 2.7.2p137, Rails 5.2.4.2, gem 3.1.4, rake, version 13.0.3
- Redmine 4.1.1，redmine_dmsf 2.4.5
- python 3.8.5
注意還沒有執行過下面這個安裝
安裝全文搜索（可選項目）
- Ubuntu爲例
sudo apt-get install xapian-omega ruby-xapian libxapian-dev xpdf poppler-utils antiword unzip catdoc libwpd-tools \ libwps-tools gzip unrtf catdvi djview djview3 uuid uuid-dev xz-utils libemail-outlook-message-perl
從下面開始真正幹活：
從Xapian官網下載以下3個文件
xapian-core-1.4.18.tar.xz xapian-bindings-1.4.18.tar.xz xapian-omega-1.4.18.tar.xz
解壓
tar -xf xapian-core-1.4.18.tar.xz tar -xf xapian-bindings-1.4.18.tar.xz tar -xf xapian-omega-1.4.18.tar.xz

不理會，繼續
添加Xapian命令路徑到系統搜索目錄中， 以讓`xapian-config --version`隨處可執行

安裝成功，警告“Xapian not available”消失了，可以編緝 `index database`路徑了：
