问题
I have recently managed (not without effort) to install tomcat 8 on a Debian 8.1 distant server. My goal is to run a webapp called geoserver
on that tomcat server. So in my /var/lib/tomcat8/webapps directory, I created a new directory called geoserver/, and in that directory I uploaded the .war file called geoserver.war.
Then I went in /var/lib/tomcat8/conf (which is actually a symbolic link that redirects me to /etc/tomcat8 and edited the tomcat-users.xml file, adding between the <tomcat-users></tomcat-users> tags the following :
<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="admin" password="*****" roles="admin-gui, manager-gui"/>
Which grants me access to the tomcat webapps manager and host-manager. In the manager, I deployed my geoserver.war file, by giving the context path and other required URLs. And after that, I can see in my apps list that /geoserver is successfully running.
But when I try to actually connect to the geoserver page (at MY_SERVER_IP:8080/geoserver), in order to work on it, I get a 404 error, saying that the requested resource (/geoserver) isn't available. For the record, other webapps, provided by default, such as /examples, work perfectly well.
I couldn't find the answer to my problem on the internet, which is why I come here to ask if anyone knows how to solve my issue. I hope my question isn't too off-topic for stackoverflow, if it is just let me know and I will post it on another website instead. Thanks in advance and have a good week-end!
EDIT : Here is what gets written in the catalina.out file when I try to start the geoserver in my tomcat webapps manager.

Some parts were written in French, I hope my translation is accurate enough.
回答1:
Move geoserver.war to /var/lib/tomcat8/webapps and restart tomcat - everything should just work at that point.
If that fails then other things to check are:
- Java 1.8 installed? GeoServer requires this
- Make sure no other programs are using port 8080
- Tomcat8 user has read/write/execute permissions on
/var/lib/tomcat8/webapps/geoserver - Check Tomcat log file in
/var/log/tomcat8/catalina.out - Check GeoServer log file in
/var/lib/tomcat8/webapps/geoserver/data/logs/geoserver.log
