Liferay two dev environment set up

The issue here is tomcat service.xml configuration

1.  change port. The default port is 8080 in Tomcat. I changed to 9999

   <Connector URIEncoding="UTF-8" port="9999" protocol="AJP/1.3" redirectPort="8443"/>

2. When I start again, it gives me another error: address already in use jvm_bind. 

<Server port="7777" shutdown="SHUTDOWN">

<Connector URIEncoding="UTF-8" port="9999" protocol="AJP/1.3" redirectPort="8443"/>

Then it will work. My original environment gives me another error related with  publish. ╮(╯▽╰)╭
