be noted: Oracle JDK is only used for personal study. can not be applied in commercial using.

I will write a document about how to install openJDK, it can be use on business.

Step1:

从官网下载jdk, Java Archive Downloads - Java SE 8 (oracle.com),

64位系统选择如下：

或参照如下链接

Installed Directory Structure of JDK (oracle.com)

Step2:

cd /usr/local

tar -zxvf jdk-8u202-linux-x64.tar.gz

建立软连接：

ln -s /usr/local/jdk1.8.0_202/bin/java /usr/local/bin/java

which java

/usr/local/bin/java

Step3:set environment

vim /etc/profile

在文件末尾追加如下：

export JAVA_HOME=/usr/local/jdk1.8.0_202

export CLASSPATH=$:CLASSPATH:$JAVA_HOME/lib/

export PATH=$PATH:$JAVA_HOME/bin

刷新：source /etc/profile

Step4:set libjli.so

find / -name libjli.so

[xiaobai@XXX /]$ ldd /usr/local/bin/java

        linux-vdso.so.1 =>  (0x00007ffc43ec1000)

        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f91c40d6000)

        libjli.so => /lib64/libjli.so (0x00007f91c3ebe000)    --if not config, it will show not found

        libdl.so.2 => /lib64/libdl.so.2 (0x00007f91c3cba000)

        libc.so.6 => /lib64/libc.so.6 (0x00007f91c38ec000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f91c42f2000)

cp /usr/local/jdk1.8.0_202/lib/amd64/jli/libjli.so /lib64

Step5:verify

[xiaobai@XXX /]$ java -version

java version "1.8.0_202"

Java(TM) SE Runtime Environment (build 1.8.0_202-b08)

Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
