}

Example 2: tomcat manage application is not working in localhost

Tomcat manager/html is not available?


You have to check if you have the folder with name manager inside the folder webapps in your tomcat.

Rubens-MacBook-Pro:tomcat rfanjul$ ls -la webapps/
total 16
drwxr-xr-x   8 rfanjul  staff   272 21 May 12:20 .
drwxr-xr-x  14 rfanjul  staff   476 21 May 12:22 ..
-rw-r--r--@  1 rfanjul  staff  6148 21 May 12:20 .DS_Store
drwxr-xr-x  19 rfanjul  staff   646 17 Feb 15:13 ROOT
drwxr-xr-x  51 rfanjul  staff  1734 17 Feb 15:13 docs
drwxr-xr-x   6 rfanjul  staff   204 17 Feb 15:13 examples
drwxr-xr-x   7 rfanjul  staff   238 17 Feb 15:13 host-manager
drwxr-xr-x   8 rfanjul  staff   272 17 Feb 15:13 manager
After that you will be sure that you have this permmint for you user in the file conf/tomcat-users.xml:

<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="test" password="test" roles="admin-gui,manager-gui"/>
restart tomcat and stat tomcat again.

sh bin/shutdown.sh 
sh bin/startup.sh
I hope that will works fine for you.
