run java jira is dependent on the environment, that is to say, if you need to install jdk and above the 1.8 version: 
install JDK part of your own Baidu
In addition, we also need to install MySQL, create the corresponding database jira, user name and password, as follows :
Note: building a database name jira, character set is UTF-8
mysql -uroot -p'xxxxxx' -e "create database jira default character set utf8 collate utf8_bin;grant all on jira.* to 'jira@’%' identified by 'jirapasswd';"
Mysql mounting portion on your own Baidu also resolved. 
After the above environment is ready, we will now begin to download and install jira.
Check how many Linux system is to download the appropriate version 
jira download site
https://www.atlassian.com/software/jira/update
Download and install
wget https://downloads.atlassian.com/software/jira/downloads/atlassian-jira-software-7.8.1-x64.bin
Add permissions after the download is complete
chmod 755 atlassian-jira-software-7.8.1-x64.bin
Then we execute this
./atlassian-jira-software-7.8.1-x64.bin
The following appears 
above the path can be modified, also can be a default 
if your 8080 port and 8005 port is occupied then this can be modified directly, you can also go down directly in the configuration file changes for a while we look at these parameters are What place
then we go down 
through the chart, we can clearly see jira installed to / opt / atlassian / jira and / var / atlassian / application-data under / jira directory, and jira listening port is 8080.
jira的主要配置文件，存放在/opt/atlassian/jira/conf/server.xml文件中
vim /opt/atlassian/jira/conf/server.xml
如果要修改端口可以在这做修改
启动
现在我们先关闭jira，然后把破解包里面的atlassian-extras-3.2.jar和mysql-connector-java-5.1.39-bin.jar两个文件复制到/opt/atlassian/jira/atlassian-jira/WEB-INF/lib/目录下。
其中atlassian-extras-3..2.jar是用来替换原来的atlassian-extras-3.2.jar文件，用作破解jira系统的。
而mysql-connector-java-5.1.39-bin.jar是用来连接mysql数据库的驱动软件包。
关闭
执行./stop-jira.sh
在/opt/atlassian/jira/atlassian-jira/WEB-INF/lib/这个目录下，找到atlassian-extras-的包看看是3点几的 然后现在对应的破解包，替换这个包然后把mysql数据库的包也放到这里包在我的百度网盘，网盘地址：
链接：https://pan.baidu.com/s/1Jfrel2pgEN57vbc2wtTr8w
提取码：mf3x
然后在启动，IP：端口进入web界面
创建第一个项目，如下：
到此 jira 7.8的安装就好了，现在看看jira的破解
破解jira，其实我们已经破解了在前面复制atlassian-extras-3.1.2.jar到/opt/atlassian/jira/atlassian-jira/WEB-INF/lib/目录下时，再次启动jira时就已经破解了。
We now log into jira view licensing information, as follows: 
by the figure, we can clearly see that we can use to jira 2033. Jira related to this installation, the crack has been all over.
How to modify memory?
vim /opt/atlassian/jira/bin/setenv.sh
