Centos安装JDK17

1、下载

sudo yum install -y wget
wget https://download.java.net/java/GA/jdk17.0.2/dfd4a8d0985749f896bed50d7138ee7f/8/GPL/openjdk-17.0.2_linux-x64_bin.tar.gz

2、解压到jvm目录

sudo tar -xvf openjdk-17.0.2_linux-x64_bin.tar.gz -C /usr/lib/jvm/

3、如果发现切换jdk命令找不到新jdk,则通过此命令添加路径

sudo alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-17.0.2/bin/java 3

4、jdk安装目录

/usr/lib/jvm
