环境
操作系统 Ubuntu 14.04.5 LTS
软件版本 atlassian-jira-software-7.1.9-x64.bin
安装前准备
安装 Vim，用于编辑配置文本
sudo apt-get install vim
安装 Java 环境
检查是否安装了 Java 环境
java -version
如果输出为类似这样，则表示当前没有安装 Java 环境，需要进行安装
The program 'java' can be found in the following packages:
* default-jre
* gcj-4.8-jre-headless
* openjdk-7-jre-headless
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
Try: apt-get install
更新包并安装相关依赖
sudo apt-get update
sudo apt-get install default-jre
sudo apt-get install default-jdk
sudo apt-get install python-software-properties
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:webupd8team/java
这里运行 sudo add-apt-repository ppa:webupd8team/java 可能会遇到以下报错，是因为没有配置好相关依赖，需要运行 sudo apt-get install software-properties-common 才能顺利执行
sudo: add-apt-repository: command not found
然后安装 Java8
sudo apt-get install oracle-java8-installer
如果报错如下：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package oracle-java8-installer
执行一次包更新就可以了
sudo apt-get update
完成后，查看 Java 版本
java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
这样，Java 已经顺利安装完成。
配置 Java 环境
查看当前 Java 安装位置
sudo update-alternatives --config java
输出如下，可直接 Enter 回车，不进行修改
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/jvm/java-8-oracle/jre/bin/java 1072 auto mode
1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode
2 /usr/lib/jvm/java-8-oracle/jre/bin/java 1072 manual mode
Press enter to keep the current choice[*], or type selection number:
之后配置 Java 环境变量
sudo vim /etc/environment
将其修改为：
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
然后应用修改
source /etc/environment
这时候查询 Java 的系统变量值：
echo $JAVA_HOME
应该可以得到：
/usr/lib/jvm/java-8-oracle

Configure which ports JIRA Software will use.
JIRA requires two TCP ports that are not being used by any other
applications on this machine. The HTTP port is where you will access JIRA
through your browser. The Control port is used to startup and shutdown JIRA.
Use default ports (HTTP: 8080, Control: 8005) - Recommended [1, Enter], Set custom value for HTTP and Control ports [2]
JIRA can be run in the background.
You may choose to run JIRA as a service, which means it will start
automatically whenever the computer restarts.
Install JIRA as Service?

其它配置
JIRA 目前版本，是需要在线激活并认证才能使用，支持免费试用 14 天。
打开后其中可以配置 mysql 或其他数据库，也可以使用内置数据库，不过内置数据库是用来演示及测试的，生产环境不建议使用。
常见问题
打开网页后，如果在配置 JIRA 的过程中，遇到网页显示 error，不用太担心，可能是服务在后台正在配置，稍微等待一会儿，过一会刷新下就可以了。
