I know this question asked more and more but my problem not resolved with that answers.
I installed tomcat 8.5.15
on centos 7 with this and when browse with server IP on port 8080 it display as expected. now my problem is access to manger page. i defined user on tomcat-users.xml
file as following:
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager"/>
<role rolename="manager-gui"/>
<user username="name" password="pass" roles="admin,admin- gui,manager,manager-gui"/>
but again i can't access to manager page.
I can add more explanation later.
