Remote monitoring Tomcat Jboss/apache

In the%jboss_home%/bin/run.sh file

java_opts= "$JAVA _opts-dprogram.name= $PROGNAME"

Modified to:

java_opts= "$JAVA _opts-dprogram.name= $PROGNAME-dcom.sun.management.jmxremote.port=9999- Dcom.sun.management.jmxremote.authenticate=false-dcom.sun.management.jmxremote.ssl=false "

#-djava.rmi.server.hostname=192.168.2.2 #this must is added for TOMACAT6

For Tomcat ... find #Execut the requested Command in catalina.sh file.

Remote monitoring can be achieved in Jconsole:
Remote Process 192.168.10.31:8950
or Service:jmx:rmi:///jndi/rmi://192.168.10.31:8950/jmxrmi

Note: 9999 indicates the monitored port number, ensures that the specified ports are not occupied, can use Netstat-an to view the ports that are already occupied, and lsof-i:portnum to view the specific applications that occupy the ports, and if firewall services are turned on, Make sure the port is accessible through the firewall; start the JBoss server

./run.sh-b192.168.1.5, the address to which the JBoss server is bound must be specified through the-b parameter (not required ...). Look at the configuration of each server)

Add Jar:

Jbossall-client.jar

Configure JMX access password

1. Modify the Java_opt parameter in the Catalina script above to
-dcom.sun.management.jmxremote.authenticate= "false" is modified to:
-dcom.sun.management.jmxremote.authenticate= "true"

2. Copy the $jre/lib/management/jmxremote.password.template file in the same directory and rename it to $jre/lib/management/ Jmxremote.password, edit Jmxremote.password, add a user name and password to allow access, such as adding a user zxwh, the password is zxme, then add a line at the end of the file:
ZXWH Zxme
Note that the user password cannot contain spaces, tab, and other characters

3. Edit the $jre_home/lib/management/jmxremote.access file to give certain permissions to the user you just added:
ZXWH readonly (or ReadWrite)

4. Verify that the users in Jmxremote.password and jmxremote.access two files are the same. Note that the configuration is invalid if there is no corresponding user in the jmxremote.access.
Note: The location of the above configuration file can be changed, the specific configuration method here no longer repeat.

5. Because passwords in Jmxremote.password are stored in plaintext, Jmxremote.password, The permissions of the Jmxremote.access file should be set to only owner-readable, and of course the user must be the user who started Tomcat.

6. Start the Jconsole to connect and enter the user and password at the user name and password.

7. Using a Password authentication method to connect can not only improve security, but also set the user's permissions. If you do not use a password authentication method, you cannot restrict the permissions of the user.

Apache:

httpd.conf

Extendedstatus on

<location/server-status>

SetHandler Server-status

Order Allow,deny

Allow from all

</location>

Http://192.168.2.8/server-status

Monitor Tomcat Another way:

In Tomcat-users.xml

<role rolename= "Manager-gui"/> <user username= "manager" password= "1234" roles= "Manager-gui"/>

Then use Shell to get status from Tomcat ...

#!/bin/sh
#$1:port; $2:user; $3:psword; $4:infoparam;
#stty-echo
Status_addr= "Http://localhost:$1/manager/status?xml=true"
