Question : Tomcat8 does not move forward once it starts deploying the WAR file. 问题：Tomcat8一旦开始部署WAR文件，就不会继续前进。 WAR File is located in and has the appropriate permissions: WAR文件位于，并具有适当的权限： 

/usr/share/tomcat8/webapps/ROOT.WAR

I can not figure out the reason why it is getting blocked and does not move forward. 我无法弄清楚为什么它被阻止并且无法继续前进的原因。 I newbie. 我是新手 I tried changing user permissions and groups but no luck. 我尝试更改用户权限和组，但没有运气。

If the build is SUCCESSFUL and If its not an entropy issue. 如果构建成功，并且不是熵问题。 It is highly possible that it is an issue related to tomcat. 这很可能是与tomcat有关的问题。

Check tomcat8 logs : 检查tomcat8日志： 

/usr/share/tomcat8/logs/tomcat.initd.logs

It will help to figure out where the problem lies. 这将有助于找出问题所在。 I just used 我刚用过 

sudo adduser -d tomcat tomcat

: Adding a user and a home directory. ：添加用户和主目录。 useradd is not recommended and activate the account with 不建议使用useradd并使用激活帐户 

sudo passwd tomcat

and then start the tomcat8 installation process. 然后启动tomcat8安装过程。
