1.append iptables rule…
1.1 append your console
[root@localhost]# iptables -t filter -A INPUT -i eth0 -d 224.0.0.0/4 -j ACCEPT
or
1.2 edit  file  “/etc/sysconfig/iptables”
[root@localhost]# vi /etc/sysconfig/iptables

-A INPUT -i eth0 -d 224.0.0.0/4 -j ACCEPT

2.restart iptables
[root@localhost]# /etc/init.d/iptables restart

3.add a -Djgroups.bind_addr=<your_ip> argument to the jvm command line
in my case
It is declared “/etc/profile” file
……
JAVA_OPTS=”-server -Xms1024m -Xmx1024m ………… -Djgroups.bind_addr=<your_ip> -Djava.net.preferIPv4Stack=true”
………
:wq!

[root@localhost]# . /etc/profile

or
append oscache.properties file
……………………………
cache.cluster.properties=UDP(mcast_addr=224.0.0.1;bind_addr=<your_ip>;mcast_port=45566;

It is installed in sever to monitor JVM Memory usage Lambda Probe.
It is free license..um just free charge!!!

Installation is easy.

1.install

1-1.Installation using Tomcat Manager (recommended)

• Download Lambda Probe .war file
• Start Tomcat and go to Manager url (ex. http://localhost:8080/manager/html)
• Upload probe.war using “WAR file to deploy” option

1-2.Installing manually

• Download Lambda Probe .war file
• Shutdown Tomcat if it is running
• Copy probe.war to $CATALINA_HOME/webapps/
• Start Tomcat

That’s too easy!!!

2.admin role Append

After you install one of above two cases,append role to ‘tomcat-users.xml’

next, It is tomcat-users.xml.
you should append monitoring auth block like under.

<?xml version=’1.0′ encoding=’utf-8′?>
<tomcat-users>
<role rolename=”manager”/>
<role rolename=”admin”/>
<!– monitoring auth[s]–>
<role rolename=”poweruser”/>
<role rolename=”probeuser”/>
<role rolename=”poweruserplus”/>
<user username=”admin” password=”admin” roles=”manager,admin,poweruser,poweruserplus,probeuser”/>
<!– monitoring auth[e]–>
<user username=”tomcat” password=”s3cret” roles=”manager,admin”/>
</tomcat-users>

3.Append Environmental variables

finally,setting Environmental variables like under.
if your computer os is window
append this    to mycoumuter>……>system variable

JAVA_OPTS
-Dcom.sun.management.jmxremote

if linux or unix

you should append this block to profile file

JAVA_OPTS=”-Dcom.sun.management.jmxremote”

It is over.

if you restart tomcat web server and connect http://localhost/manager/html

you will see “/probe” context.

.일단 서버에 bind 서버가 깔려있는지를 알아봅니다.
 버젼을 확인해 봅니다.(rpm의 경우)

> rpm -qa bind*
bind-libs-9.3.3-9.0.1.el5
bind-utils-9.3.3-9.0.1.el5
bind-9.3.3-9.0.1.el5
bind-chroot-9.3.3-9.0.1.el5

안되어 있다면 설치를 합니다.(설치는 생략합니다.)

.설정파일에 추가된 도메인을 설정합니다.
> cd /var/named/chroot/etc
> vi named.conf
……
zone “[first.co.kr]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
zone “[second.com]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
zone “[third.com]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
* [] 부분을 통째로 자기 환경에 맞게 수정하여야 합니다.

.서브도메인을 구성할 경우에는 domain.zone 파일(first.comt.zone) 을 수정합니다.
.named 데몬을 재구동 합니다.
> /etc/init.d/named restart
