2、下载JDK17

linux 系统下，使用wget下载

$ wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz

3、解压jdk-17_linux-x64_bin.tar.gz

4、复制到/usr/local/jdk-17

5、配置环境变量

$ sudo vim /etc/profile

webrx@us:~$ cat /etc/profile

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))

# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "${PS1-}" ]; then

if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then

# The file bash.bashrc already sets the default PS1.

# PS1='\h:\w\$ '

if [ -f /etc/bash.bashrc ]; then

. /etc/bash.bashrc

else

if [ "`id -u`" -eq 0 ]; then

PS1='# '

else

PS1='$ '

if [ -d /etc/profile.d ]; then

for i in /etc/profile.d/*.sh; do

if [ -r $i ]; then

. $i

done

unset i

export JAVA_HOME=/usr/local/jdk-17

export CLASSPATH=.:$JAVA_HOME/lib

export PATH=.:$JAVA_HOME/bin:$JAVA_HOME/lib:$PATH
