Problemløsning ved oppstart av JBoss Application Server på CentOS 7
I løpet av helgen eksperimenterte jeg med JBoss Application Server på CentOS 7. Jeg installerte versjon 7.1.1, men oppdaget at serveren hang ved oppstart.
[[email protected] bin]# ./standalone.sh

Jeg ventet noen minutter, uten at noe skjedde.
Opplevde du det samme? Ingen grunn til bekymring!
Det ser ut til at det er et kjent problem med JBoss 7 og Java 8. Løsningen er å bruke Java 7. Det første du bør gjøre er å sjekke hvilken Java-versjon du bruker.
[[email protected] bin]# java -version
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-b15)
OpenJDK 64-Bit Server VM (build 25.111-b15, mixed mode)
[[email protected] bin]#
Som du ser ovenfor, brukte jeg Java 8, og jeg måtte bytte til Java 7.
Dersom du bruker CentOS, kan du bytte til en tidligere Java-versjon med denne kommandoen:
update-alternatives --config java
Dette vil gi deg muligheten til å velge ønsket Java-versjon:
[[email protected] bin]# update-alternatives --config java
There are 2 programs which provide 'java'.
Selection Command
-----------------------------------------------
1 java-1.7.0-openjdk.x86_64 (/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.121-2.6.8.0.el7_3.x86_64/jre/bin/java)
*+ 2 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-2.b15.el7_3.x86_64/jre/bin/java)
Enter to keep the current selection[+], or type selection number:
Skriv inn 1, så er du klar.
Dersom du bruker RHEL eller ikke har Java 7 installert, må du installere den og legge til i PATH.
Etter at jeg byttet til Java 7, startet JBoss 7 problemfritt.

Jeg håper dette er til hjelp. Lær mer om JBoss EAP administrasjon og konfigurasjon her.
