Install Java Runtime Environment 1.8.0

Step 1: download https://www.java.com/en/download/manual.jsp

For CentOS 32bits, use Linux RPM

wget "https://sdlc-esd.oracle.com/ESD6/JSCDL/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jre-8u191-linux-i586.rpm?GroupName=JSC&FilePath=/ESD6/JSCDL/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jre-8u191-linux-i586.rpm&BHost=javadl.sun.com&File=jre-8u191-linux-i586.rpm&AuthParam=1546769589_67418eadf0052d11df6c6f17b4703a16&ext=.rpm" -O jre-8u191-linux-i586.rpm

For CentOS 64bits, use Linux x64 RPM

mkdir /usr/java
cd /usr/java
wget http://javadl.oracle.com/webapps/download/AutoDL?BundleId=230531_2f38c3b165be4555a1fa6e98c45e0808 -O jre-8u161-linux-x64.rpm

Step 2: install:
32bits

rpm -ivh jre-8u191-linux-i586.rpm

64bits

rpm -ivh jre-8u161-linux-x64.rpm

Result:

[root@tutorialspots java]# rpm -ivh jre-8u161-linux-x64.rpm

You should delete RPM file after the installation:

rm -f jre-8u161-linux-x64.rpm

Step 3: create file /etc/profile.d/java.sh with these lines:

export JAVA_HOME=/usr/java/jre1.8.0_161
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

By using this command:

vi /etc/profile.d/java.sh

Step 4:

export JAVA_HOME=/usr/java/jre1.8.0_161
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

Check:

[root@tutorialspots ~]# java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

Install java-1.8.0-openjdk-headless or java-1.8.0-openjdk
Change step 1 and 2:

yum install java-1.8.0-openjdk-headless

or

yum install java-1.8.0-openjdk

result:

[root@tutorialspots ~]# yum install java-1.8.0-openjdk
