<!– Note: A “Server” is not itself a “Container”, so you may not
define subcomponents such as “Valves” at this level.

UserDatabaseRealm to authenticate users

<!– A “Service” is a collection of one or more “Connectors” that share
a single “Container” Note: A “Service” is not itself a “Container”,
so you may not define subcomponents such as “Valves” at this level.
Documentation at /docs/config/service.html
–>
<Service name=”Catalina”>

<!–The connectors can use a shared executor, you can define one or more named thread pools–>
<!–
<Executor name=”tomcatThreadPool” namePrefix=”catalina-exec-”
maxThreads=”150″ minSpareThreads=”4″/>
–>
<!– A “Connector” represents an endpoint by which requests are received
and responses are returned. Documentation at :
Java HTTP Connector: /docs/config/http.html
Java AJP Connector: /docs/config/ajp.html
APR (HTTP/AJP) Connector: /docs/apr.html
Define a non-SSL/TLS HTTP/1.1 Connector on port 8080
–>
<Connector port=”8080″ protocol=”HTTP/1.1″
connectionTimeout=”20000″
redirectPort=”8443″ />
<!– A “Connector” using the shared thread pool–>
<!–
<Connector executor=”tomcatThreadPool”
port=”8080″ protocol=”HTTP/1.1″
connectionTimeout=”20000″
redirectPort=”8443″ />
–>
<!– Define a SSL/TLS HTTP/1.1 Connector on port 8443
This connector uses the NIO implementation with the JSSE engine. When
using the JSSE engine, the JSSE configuration attributes must be used.
–>
<!–
<Connector port=”8443″ protocol=”org.apache.coyote.http11.Http11NioProtocol”
maxThreads=”150″ SSLEnabled=”true”>
<SSLHostConfig>
<Certificate certificateKeystoreFile=”conf/localhost-cust.jks”
type=”CUST” />
</SSLHostConfig>
</Connector>
–>
<!– Define a SSL/TLS HTTP/1.1 Connector on port 8443 with HTTP/2
This connector uses the APR/native implementation. When using the
APR/native implementation or the OpenSSL engine with NIO or NIO2 then
the OpenSSL configuration attributes must be used.
–>
<!–
<Connector port=”8443″ protocol=”org.apache.coyote.http11.Http11AprProtocol”
maxThreads=”150″ SSLEnabled=”true” >
<UpgradeProtocol className=”org.apache.coyote.http2.Http2Protocol” />
<SSLHostConfig>
<Certificate certificateKeyFile=”conf/localhost-cust-key.pem”
certificateFile=”conf/localhost-cust-cert.pem”
certificateChainFile=”conf/localhost-cust-chain.pem”
type=”CUST” />
</SSLHostConfig>
</Connector>
–>

<!– Define an AJP 1.3 Connector on port 8009 –>
<Connector port=”8009″ protocol=”AJP/1.3″ redirectPort=”8443″ />
<!– An Engine represents the entry point (within Catalina) that processes
every request. The Engine implementation for Tomcat stand alone
analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host).
Documentation at /docs/config/engine.html –>

<!– You should set jvmRoute to support load-balancing via AJP ie :
<Engine name=”Catalina” defaultHost=”localhost” jvmRoute=”jvm1″>
–>
<Engine name=”Catalina” defaultHost=”localhost”>

<!–For clustering, please take a look at documentation at:
/docs/cluster-howto.html (simple how to)
/docs/config/cluster.html (reference documentation) –>
<!–
<Cluster className=”org.apache.catalina.ha.tcp.SimpleTcpCluster”/>
–>

<!– Use the LockOutRealm to prevent attempts to guess user passwords
via a brute-force attack –>
<Realm className=”org.apache.catalina.realm.LockOutRealm”>
<!– This Realm uses the UserDatabase configured in the global JNDI
resources under the key “UserDatabase”. Any edits
that are performed against this UserDatabase are immediately
available for use by the Realm. –>
<Realm className=”org.apache.catalina.realm.UserDatabaseRealm”
resourceName=”UserDatabase”/>
</Realm>

<Host name=”localhost” appBase=”webapps”
unpackWARs=”true” autoDeploy=”true”>

<!– SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html –>
<!–
<Valve className=”org.apache.catalina.authenticator.SingleSignOn” />
–>

<!– Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern=”common” –>
<Valve className=”org.apache.catalina.valves.AccessLogValve” directory=”logs”
prefix=”localhost_access_log” suffix=”.txt”
pattern=”%h %l %u %t &quot;%r&quot; %s %b” />

</Host>
</Engine>
</Service>
</Server>

NOTE: By default, no user is included in the “manager-gui” role required
to operate the “/manager/html” web application. If you wish to use this app,
you must define such a user – the username and password are arbitrary. It is
strongly recommended that you do NOT use one of the users in the commented out
section below since they are intended for use with the examples web
application.
–>
<!–
NOTE: The sample user and role entries below are intended for use with the
examples web application. They are wrapped in a comment and thus are ignored
when reading this file. If you wish to configure these users for use with the
examples web application, do not forget to remove the <!.. ..> that surrounds
them. You will also need to set the passwords to something appropriate.
