Good, it's the latest image. I'll check.

[jangaraj]

/usr/bin/java will be used

[root@8982201fbbe5 /]# ls -lah /usr/bin/java
lrwxrwxrwx 1 root root 22 Jan 10 11:58 /usr/bin/java -> /etc/alternatives/java
[root@8982201fbbe5 /]# ls -lah /etc/alternatives/java
lrwxrwxrwx 1 root root 70 Jan 10 11:58 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-3.b17.el7.x86_64/jre/bin/java

[xiaoping378]

yes, the fix is working well.
But ..
Default the JAVA_HOME should point to the directory containing a bin/java.

[jangaraj]

Could you check docker image monitoringartist/zabbix-2.4 (only latest 2.4.7 is available there) and propose correct settings for java please? This image will be new community Zabbix image soon (PR #21).

[xiaoping378]

my suggestions:

JAVA_HOME=/usr/lib/jvm/jre
JAVA=$JAVA_HOME/bin

JAVA=$JAVA_HOME/bin
sorry, the env java is a wrong path.

[jangaraj]

Thank you.

  JAVA_HOME=/usr/lib/jvm/jre \
  JAVA=/usr/lib/jvm/jre/bin \

Please retest image monitoringartist/zabbix-2.4

[xiaoping378]

Sorry, java is not OK
JAVA=/usr/lib/jvm/jre/bin

Both of below are OK.

• JAVA=$JAVA_HOME/bin/java
• JAVA=/usr/bin/java

[jangaraj]

No problem.

JAVA_HOME=/usr/lib/jvm/jre \
JAVA=/usr/bin/java \

Please recheck monitoringartist/zabbix-2.4.

[xiaoping378]

OK, work well

[jangaraj]

Fixed in new Docker image zabbix/zabbix-2.4 (zabbix/zabbix-3.0).
