Centos Linux 系统部署java程序 (一、安装JAVA运行时环境【JRE】)

下载

IBM jdk的下载地址： https://developer.ibm.com/languages/java/semeru-runtimes/downloads/

选择所需版本，我这里选择的是java8版本，由于服务器上只需要运行JAVA程序，下载JRE即可

下载地址：ibm-semeru-open-jre_x64_linux_8u402b06_openj9-0.43.0.tar.gz

解压

找到刚才下载的文件及所在目录，在该目录下执行以下命令 tar -zxvf ibm-semeru-open-jre_x64_linux_8u402b06_openj9-0.43.0.tar.gz

设置环境变量

设置环境变量有多种方法，我这里选用一种，编辑根目录下的.bashrc文件，千万记得带点，否则无法生效。

vi ~/.bashrc

在文件的末尾，换行，加上以下内容

export JAVA_HOME=[当前路径]/jdk8u402-b06-jre

export PATH=$PATH:$JAVA_HOME/bin

把其中的当前路径改为实际的路径即可，当然这个默认的文件夹名称jdk8u402-b06-jre也可以改成你比较喜欢的名称。

改完后，保存文件 (Esc + :wq! + 回车)

环境变量生效

需要执行source命令让配置立即生效

source ~/.bashrc

检验

通过java查看版本命令的结果，来确认程序是否已安装成功

java -version

检验结果如下，则表示安装成功，否则会找不到java指令
