1.安装jdk

官方下载链接:

#需要注册才能下载jdk
https://www.oracle.com/java/technologies/downloads/#java

这里我选择二进制安装为jdk-8u321-linux-x64.tar.gz

[root@rocky8 ~]#tar xf jdk-8u321-linux-x64.tar.gz -C /usr/local
[root@rocky8 ~]#cd /usr/local/
[root@rocky8 local]#ls
bin  etc  games  include  jdk1.8.0_321  lib  lib64  libexec  sbin  share  src
[root@rocky8 local]#ln -s jdk1.8.0_321/ jdk
#配置环境变量
[root@rocky8 local]#vim /etc/profile.d/jdk.sh
export JAVA_HOME=/usr/local/jdk
export PATH=$PATH:$JAVA_HOME/bin
#生效环境变量
[root@rocky8 local]#. /etc/profile.d/jdk.sh

#验证安装
[root@rocky8 local]#java -version
java version "1.8.0_321"
Java(TM) SE Runtime Environment (build 1.8.0_321-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.321-b07, mixed mode)
[root@rocky8 local]#which java
/usr/local/jdk/bin/java

2.安装tomcat

官方网站:

https://tomcat.apache.org/

这次安装下载9版本的tomcat

#解压文件
[root@rocky8 ~]#tar xf apache-tomcat-9.0.59.tar.gz -C /usr/local/
[root@rocky8 ~]#cd /usr/local/
[root@rocky8 local]#ln -s apache-tomcat-9.0.59/ tomcat
#设置PATH变量
[root@rocky8 local]#echo 'PATH=/usr/local/tomcat/bin:$PATH' > /etc/profile.d/tomcat.sh
[root@rocky8 local]#cat /etc/profile.d/tomcat.sh
PATH=/usr/local/tomcat/bin:$PATH
[root@rocky8 local]#. /etc/profile.d/tomcat.sh
[root@rocky8 local]#echo $PATH
/usr/local/tomcat/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/jdk/bin
