安装

tomcat需要jdk环境，最常用的就是1.8版本的，安装jdk我就不再多说了

把包上传上来
[root@localhost ~]# tar -xf apache-tomcat-9.0.14.tar.gz -C /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
apache-tomcat-9.0.14  bin  etc  games  include  jdk  lib  lib64  libexec  sbin  share  src
[root@localhost local]# mv apache-tomcat-9.0.14 tomcat
[root@localhost local]# cd tomcat/
[root@localhost tomcat]# cd bin/
[root@localhost bin]# ls
