Installare WildFly 9 su Centos6

WildFly, precedentemente noto come JBoss AS o semplicemente JBoss, è un Application Server open source che implementa le specifiche Java EE.
WildFly è un sistema multipiattaforma, interamente realizzato in Java.

Prerequisito installare JDK 
JDK = java development kit
Per verificare se java è installato, eseguire il comando:
[root@coslab02 conf.d]# java -version
java version "1.7.0_191" OpenJDK Runtime Environment (rhel-2.6.15.4.el6_10-x86_64 u191-b01) OpenJDK 64-Bit Server VM (build 24.191-b01, mixed mode)

Per trovare la directory di installazione di java:
[root@coslab02 ~]# which java
/usr/bin/java
[root@coslab02 ~]# ll /usr/bin/java
lrwxrwxrwx. 1 root root 22  6 set  2018 /usr/bin/java -> /etc/alternatives/java
[root@coslab02 ~]# ll /etc/alternatives/java
lrwxrwxrwx. 1 root root 46  6 set  2018 /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

La JAVA_HOME è /usr/lib/jvm/jre-1.7.0-openjdk.x86_64


Effettuare il download di wildfly sotto la directory /opt
Collegarsi a https://wildfly.org/downloads/
Cliccare con il pulsante destro sul file zip di di Java EE Full & Web Distribution della versione 9.2 e copiare il link.

[root@coslab02 opt]# wget https://download.jboss.org/wildfly/9.0.1.Final/wildfly-9.0.1.Final.zip

Unzippare il file
#unzip wildfly-9.0.1.Final.zip

[root@coslab02 opt]# ls -lrt
drwxr-xr-x. 10 root root      4096 23 lug  2015 wildfly-9.0.1.Final
-rw-r--r--.  1 root root 133617224 24 lug  2015 wildfly-9.0.1.Final.zip

Creare l'utente
[root@coslab02 opt]# useradd -s /bin/bash wildfly

Cambiare la password
[root@coslab02 wildfly]# passwd wildfly


Crea un link simbolico a wildfly
[root@coslab02 opt]# ln -s /opt/wildfly-9.0.1.Final /opt/wildfly
[root@coslab02 opt]# ls -lrt
drwxr-xr-x. 10 root root      4096 23 lug  2015 wildfly-9.0.1.Final
lrwxrwxrwx.  1 root root        24  7 ott 15:59 wildfly -> /opt/wildfly-9.0.1.Final

Cambiare il proprietario
[root@coslab02 opt]# chown -R wildfly:wildfly wildfly-9.0.1.Final

[root@coslab02 opt]# ls -lrt
drwxr-xr-x. 10 wildfly wildfly 4096 23 lug  2015 wildfly-9.0.1.Final
lrwxrwxrwx.  1 root    root      24  7 ott 15:59 wildfly -> /opt/wildfly-9.0.1.Final

Esportare nel batch profile dell'utente wildfly la variabile JAVA_HOME.
cd /home/wildfly
[root@coslab02 wildfly]# ls -lart
totale 24
-rw-r--r--. 1 wildfly wildfly  124 23 mar  2017 .bashrc
-rw-r--r--. 1 wildfly wildfly  176 23 mar  2017 .bash_profile
-rw-r--r--. 1 wildfly wildfly   18 23 mar  2017 .bash_logout
-rw-r--r--. 1 wildfly wildfly  171 13 mar  2018 .kshrc

[root@coslab02 wildfly]# vi .bash_profile
JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH

[root@coslab02 wildfly]# .  ./.bash_profile

Come verifica accedere come wildfly e controllare la versione di java sia la stessa visibile come root.
[root@coslab02 wildfly]# su - wildfly
[wildfly@coslab02 ~]$ java -version
java version "1.7.0_191"
OpenJDK Runtime Environment (rhel-2.6.15.4.el6_10-x86_64 u191-b01)
OpenJDK 64-Bit Server VM (build 24.191-b01, mixed mode)

Eseguire wildfly come un servizio

[root@coslab02 init.d]# cp /opt/wildfly/bin/init.d/wildfly-init-redhat.sh   /etc/init.d/wildfly

Dar i permessi allo script

[root@coslab02 init.d]# chmod 755 wildfly

Creare la directory contenente il PID file per il servizio wildfly

mkdir /var/run/wildfly/

chown -R wildfly:wildfly /var/run/wildfly/

Copiare il file di configurazione di wildfly sotto /etc/deafult e modificarlo.
[root@coslab02 bin]# cp /opt/wildfly/bin/init.d/wildfly.conf    /etc/default/

Fare le seguenti modifiche:
vi wildfly.conf

## Location of JDK
JAVA_HOME="/usr/lib/jvm/jre-1.7.0-openjdk.x86_64"

## Location of WildFly

JBOSS_HOME="/opt/wildfly"

## The username who should own the process.

JBOSS_USER=wildfly

## The mode WildFly should start, standalone or domain

JBOSS_MODE=standalone

## Configuration for standalone mode

JBOSS_CONFIG=standalone.xml

## The amount of time to wait for startup
STARTUP_WAIT=60
## The amount of time to wait for shutdown
SHUTDOWN_WAIT=60
## Location to keep the console log
JBOSS_CONSOLE_LOG="/var/log/wildfly/console.log"
# Location of lockfile on redhat
JBOSS_LOCK="/var/lock/subsys/wildfly"

Per rendere Wildfly accessibile dall'esterno cambiare 127.0.0.1 in 0.0.0.0 nel seguente file.

vi /opt/wildfly/standalone/configuration/standalone.xml

<interface name="management">

            <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>

        </interface>

        <interface name="public">

            <inet-address value="${jboss.bind.address:127.0.0.1}"/>

        </interface>

        <!-- TODO - only show this if the jacorb subsystem is added  -->

        <interface name="unsecure">

            <!--

              ~  Used for IIOP sockets in the standard configuration.

              ~                  To secure JacORB you need to setup SSL

              -->

            <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/>

        </interface>

    </interfaces>

Creare la directory
mkdir /opt/wildfly/standalone/tmp/vfs/temp
chown -R wildfly:wildfly opt/wildfly/standalone/

cd /opt/wildfly/standalone/configuration/
chown -R wildfly:wildfly standalone_xml_history


Aggiungere un utente che sia abilitato ad accedere alla console di amministratore.
