IGOS Nusantara dan Sun Java
Dari IGNwiki
Beberapa aplikasi berbasis web yang memakai Java tidak dapat jalan jika memakai OpenJDK, sehingga harus memasang Sun JDK atau JRE.
Daftar isi
Unduh Sun JDK atau JRE
Unduh Sun JDK atau JRE dari http://java.sun.com/javase/downloads/index.jsp
Panduan berikut untuk Sun Java versi 8 update 25. 32bit
- jre-8u25-linux-i586.rpm
- jdk-8u25-linux-i586.rpm
64bit
- jre-8u25-linux-x64.rpm
- jdk-8u25-linux-x64.rpm
Untuk versi Sun Java lainnya, silakan lakukan penyesuaian dengan nama berkas rpm.
Pasang Sun JDK atau JRE
Pasang salah satu:
# rpm -ivh jre-8u25-linux-i586.rpm
atau
# rpm -ivh jdk-8u25-linux-i586.rpm
Ubah ke Sun JRE
Jika sebelumnya telah memasang OpenJDK, maka sistem harus diubah agar memakai Sun JDK, lakukan:
## java ## # alternatives --install /usr/bin/java java /usr/java/latest/jre/bin/java 20000
atau
# alternatives --install /usr/bin/java java /usr/java/latest/bin/java 20000
## javaws ## # alternatives --install /usr/bin/javaws javaws /usr/java/latest/jre/bin/javaws 20000 ## Java Browser (Mozilla) Plugin 32-bit ## # alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so /usr/java/latest/jre/lib/i386/libnpjp2.so 20000 ## Pasang javac hanya jika memasang Java Development Kit (JDK) # alternatives --install /usr/bin/javac javac /usr/java/latest/bin/javac 20000 # alternatives --install /usr/bin/jar jar /usr/java/latest/bin/jar 20000
Mengatur path ke JDK
Setelah instalasi lakukan pengaturan variabel JAVA_HOME ke /etc/profile atau ke $HOME/.bash_profile
Gunakan Java JDK dan JRE versi terakhir (/usr/java/latest)
## export JAVA_HOME JDK/JRE ## export JAVA_HOME="/usr/java/latest"
