本文介绍在Ubuntu 18.04、Ubuntu 16.04系统上安装Openfire XMPP chat server（Openfire XMPP聊天服务器）的方法。Openfire是一种利用XMPP/Jabber协议的流行且功能强大的即时消息（IM）服务器， Openfire还具有体面的Presence Server的所有功能。
一、更新系统包 确保Ubuntu 18.04系统上的所有软件包都是最新的，运行以下命令： $ sudo apt-get update $ sudo apt-get upgrade
二、安装JAVA JDK 更新软件包后，如果你愿意，请安装openjdk-8-jdk或9，openjdk-8-jdk包可以在Ubuntu官方存储库中找到，通过运行命令进行安装： $ sudo apt-get install openjdk-8-jdk $ java -version openjdk version "1.8.0_171" OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11) OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
三、安装数据库 你可以从支持的数据库服务器中选择数据库：MySQL/MariaDB或PostgreSQL，对于此设置，我们将安装MariaDB或MySQL，参考： 在Ubuntu 18.04系统上安装MariaDB 10.4的步骤 在Ubuntu 18.04/16.04命令行上安装MySQL 8.0.11的全过程 创建数据库用户： $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 5 Server version: 5.7.22-0ubuntu18.04.1 (Ubuntu) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> create database openfire; Query OK, 1 row affected (0.00 sec) mysql> GRANT ALL PRIVILEGES ON openfire.* TO openfire@localhost IDENTIFIED BY 'password123!'; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye 稍后我们将导入Openfire数据库数据。
四、下载并安装Openfire 下载Openfire包，当前的版本是Openfire 4.3.2： $ wget https://www.igniterealtime.org/downloads/download-landing.jsp?file=openfire/openfire_4.3.2_all.deb \ -O openfire.deb 我们现在安装它： $ sudo dpkg -i openfire.deb Selecting previously unselected package openfire. (Reading database ... 76619 files and directories currently installed.) Preparing to unpack openfire.deb ... Unpacking openfire (4.3.2) ... Setting up openfire (4.3.2) ... adduser: Warning: The home directory `/var/lib/openfire' does not belong to the user you are currently creating. Processing triggers for ureadahead (0.100.0-20) ... Processing triggers for systemd (237-3ubuntu10) ... 检查申请状态： $ systemctl status openfire openfire.service - LSB: Start/stop openfire jabber server Loaded: loaded (/etc/init.d/openfire; generated) Active: Docs: man:systemd-sysv-generator(8) Tasks: 22 (limit: 1153) CGroup: /system.slice/openfire.service └─28050 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -server -DopenfireHome=/usr/share/openfire -Dopenfire.lib.dir=/usr/share/openfire/lib -classpath /usr/sh Feb 9 10:00:06 haproxy-01 systemd[1]: Starting LSB: Start/stop openfire jabber server...

Feb 9 10:00:06 haproxy-01 systemd[1]: Started LSB: Start/stop openfire jabber server. 导入Openfire数据库架构： $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 6 Server version: 5.7.22-0ubuntu18.04.1 (Ubuntu) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> use openfire; Database changed mysql> source /usr/share/openfire/resources/database/openfire_mysql.sql; mysql> show tables;
五、配置防火墙和访问Openfire UI 如果你有活动的防火墙服务，则需要允许Openfire端口，我的Ubuntu 18.04系统运行ufw： $ sudo ufw enable $ for i in 9090 9091 5222 7777; do sudo ufw allow $i; done 参考：在Ubuntu 18.04系统中使用UFW设置防火墙。 要访问GUI，你将使用服务器的IP地址和端口9090： http://<server-ip|domain>:9090 将获得Openfire配置窗口：
选择默认语言，然后单击继续，在服务器设置窗口中，设置域并单击继续按钮：
我们将使用以下配置参数： 数据库驱动程序预设：MySQL JDBC驱动程序类：com.mysql.jdbc.Driver 数据库URL：jdbc:mysql://127.0.0.1/openfire?useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8 用户名：openfire 密码：password123！
单击继续并使用配置文件设置上的默认选项，你可以稍后添加LDAP等外部身份验证机制：
设置管理员用户邮箱地址和密码：
单击继续完成配置，这个时候将出现登录页面，使用admin作为用户名登录并提供上面配置的密码：
如果一切顺利，将出现Openfire管理界面：
至此，配置安装Openfire全部完成。
