1：下载Tomcat的tar包

wget https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.34/bin/apache-tomcat-8.5.34.tar.gz

2：解压缩tar包

tar -zxvf apache-tomcat-8.5.34.tar.gz

3：移动到目录/usr/local（随意，你应该不会安装到root目录吧？）

mv apache-tomcat-8.5.34 /usr/local/apache-tomcat-8.5.34

4：Tomcat端口默认8080

vi /usr/local/apache-tomcat-8.5.34/conf/server.xml

修改Connector port="8080" protocol="HTTP/1.1"

5.启动tomcat

/usr/local/apache-tomcat-8.5.34/bin/startup.sh

Ps：确定已安装jdk
