First install java:
1. yum remove java
this will remove the java that does not work on low ram.
2. install the ibm jre
idk if these links will expire or not:
Ibm Jre x86
Ibm Jre 64-bit
if these don’t work, you will need to login:
download java se 6 for your architecture
3. install using yum localinstall –nogpgcheck filename
filename is the name of the ibm jre rpm package.
4. ln -s /opt/ibm/java-i386-60/jre/bin/java /usr/bin/java
or ln -s /opt/ibm/java-x86_64-60/jre/bin/java /usr/bin/java
i just found out you can also use a .bashrc alias:
open .bashrc with your favorite text editor
add: alias java=’/opt/ibm/java-i386-60/jre/bin/java’
add: alias java=’/opt/ibm/java-x86_64-60/jre/bin/java’
5. its installed and ready to go!
now for minecraft, all you need to do now is java -jar minecraft_server.jar!
