如何在Ubuntu 16.04上安装和配置XWiki
XWiki是一个免费的开放源码wiki软件，运行在像Tomcat，JBoss等servlet容器上。XWiki使用MySQL或PostgreSQL等数据库来存储信息。 XWiki允许我们存储结构化数据并在维基界面中执行服务器脚本。 您可以托管多个博客，并使用XWiki管理或查看您的文件和文件夹。
XWiki具有很多功能，其中一些列在下面：
- 支持版本控制和ACL。
- 允许您使用通配符搜索完整的wiki。
- 轻松将wiki页面导出为PDF，ODT，RTF，XML和HTML。
- 内容组织和内容导入。
- 使用所见即所得的编辑器编辑页面。
要求
- 运行Ubuntu 16.04的服务器
- 具有sudo权限的非root用户。
更新系统
在开始之前，您需要将Ubuntu资源库更新到最新版本。 您可以使用以下命令执行此操作：
sudo apt-get update -y
sudo apt-get upgrade -y
存储库更新后，重新启动系统以应用所有更新。
安装Java
Xwiki是一个基于Java的应用程序，所以你需要先安装Java 8。 默认情况下，Java 8在Ubuntu存储库中不可用。 您可以通过将webupd8team PPA存储库添加到系统来安装Java 8。
首先，运行以下命令添加PPA：
sudo add-apt-repository ppa:webupd8team/java
接下来，使用以下命令更新存储库：
sudo apt-get update -y
一旦存储库是最新的，您可以通过运行以下命令来安装Java 8：
sudo apt-get install oracle-java8-installer -y
安装Java之后，可以使用以下命令检查Java的版本：
java -version
您应该看到以下输出：
Java version "1.8.0_91" Java(TM) SE Runtime Environment (build 1.8.0_91-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
下载并安装Xwiki
接下来，您需要下载XWiki提供的安装文件。 您可以使用以下命令下载它：
wget http://download.forge.ow2.org/xwiki/xwiki-enterprise-installer-generic-8.1-standard.jar
下载完成后，您可以使用java命令安装下载的软件包文件，如下所示：
sudo java -jar xwiki-enterprise-installer-generic-8.1-standard.jar
您应该看到以下输出：

XWiki现在正在运行，是时候访问XWiki的网页界面。
访问XWiki
XWiki在端口8080上运行，所以你需要通过防火墙允许端口8080。 首先，使用以下命令启用UFW防火墙：
sudo ufw enable
接下来，使用以下命令通过UFW防火墙允许端口8080 ：
sudo ufw allow 8080/tcp
接下来，通过运行以下命令重新加载防火墙规则以应用所有更改：
sudo ufw reload
您可以使用以下命令获取UFW防火墙的状态：
sudo ufw status
现在，打开你的浏览器并输入URL http：// your-server-ip：8080 ，你将被重定向到XWiki主页，如下所示：
您可以随时通过在终端中按Ctrl + C按钮来停止XWiki服务器。
结论
