XWIKI是一款免费的和OpenSource Advanced Wiki软件，它用Java编写。
它在像JBoss，Tomcat等这样的Servlet容器上运行。

它使用诸如MySQL或者PostgreSQL等数据库来存储其信息。

在本教程中，我将解释如何在Ubuntu 18.04上安装XWiki软件，使用其独立分发，这是最快和最简单的方法，因为XWiki所需的所有组件都会自动安装在服务器上。

此XWIKI软件提供内置的XWIKI，具有便携式数据库(HSQLDB)和轻量级Java容器(Docker)。

XWIKI安装步骤

在开始任何安装之前，我建议使用"APT-UPDATE"更新系统软件。
如果此之前未安装，则可以安装WGET和"屏幕"包。

#apt-get update -y
#apt install wget screen

第1步：安装Java

如前所述，XWIKI是基于Java的应用程序，因此我们需要安装"Java 8"或者以上以满足其软件要求。
默认情况下，默认的Ubuntu存储库中不可用Java 8.
因此，我们可以通过向系统添加Webupd8team PPA存储库来安装支持的Java。

#add-apt-repository ppa:webupd8team/java
#apt-get update -y

添加PPA存储库后，我们需要更新存储库包。
一旦完成，我们可以通过在下面运行此命令来安装所需的java 8：

#apt-get install oracle-java8-installer -y

You can confirm the Java version installed.
~# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

第2步：下载并安装XWIKI

首先，我们需要为此XWiki安装开始新的屏幕会话。
现在我们需要下载所有平台上工作的通用安装程序。
它只需要在系统上安装Java。
我们可以使用以下命令下载XWiki Generic Installer文件：

#screen -U -S xwiki
#wget http://download.forge.ow2.org/xwiki/xwiki-enterprise-installer-generic-8.1-standard.jar

下载此安装程序后，我们可以使用Java安装此下载的包。
安装程序将我们带到各种交互式部分，如下所示，它要求输出，如输入1(接受或者继续)/2(退出)/3(REDISPLAY)从我们继续进行安装。
大多数提示都可以用`1(接受或者继续)回答。
安装程序非常自我解释，因此我们只需按照说明操作。

应用程序将在端口8080上自动启动。
我们需要等待几分钟才能启动应用程序。
一旦完成，我们就可以通过端口8080上的域或者服务器IP访问XWIKI。
不要关闭显示的屏幕终端窗口。
我们的XWIKI服务器需要运行。
我们可以通过终止此屏幕终端来停止此XWIKI服务器。

PS：默认情况下，应用程序在端口8080上运行。
但如果我们想使用自定义端口8081，请确保在端口8081上没有任何东西，并使用以下命令启动XWiki：

#bash start_xwiki.sh -p 8081

第3步：启动应用程序

启动XWIKI后，我们可以将浏览器指向"http：//serverip或者hostname：8080 /"以访问Web界面。

我们可以使用默认的admin用户(第一个字母为大写)登录管理面板，其默认密码是admin(小写)。
