這篇文章主要介紹了如何卸載linux自帶openjdk并安裝sun jdk,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
Linux系統中自帶的openjdk可能不符合我們工作的需要。
[hadoop@master ~]$ java -version``openjdk version "1.8.0_222-ea"``OpenJDK Runtime Environment (build 1.8.0_222-ea-b03)``OpenJDK 64-Bit Server VM (build 25.222-b03, mixed mode)
檢測jdk安裝包
[hadoop@master ~]$ rpm -qa | grep java``python-javapackages-3.4.1-11.el7.noarch``javapackages-tools-3.4.1-11.el7.noarch``tzdata-java-2019b-1.el7.noarch``java-1.8.0-openjdk-headless-1.8.0.222.b03-1.el7.x86_64``java-1.8.0-openjdk-1.8.0.222.b03-1.el7.x86_64``[hadoop@master ~]$
卸載openjdk

上傳安裝介質并解壓
[hadoop@master ~]$ ``sudo` `tar` `-xzf jdk-8u191-linux-x64.``tar``.gz -C ``/usr/lib/jvm
設置環境變量,在/etc/profile最前面加上
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_191``export JRE_HOME=${JAVA_HOME}/jre``export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib``export PATH=${JAVA_HOME}/bin:$PATH
最后生效一下source /etc/profile
