export TOMCAT_HOME=/usr/local/tomcat/apache-tomcat-8.5.29
export CATALINA_HOME=/usr/local/tomcat/apache-tomcat-8.5.29/
export JRE_HOME=/usr/java/jdk1.8.0_161/jre
export JAVA_HOME=/usr/java/jdk1.8.0_161
4.修改端口
vi /usr/local/tomcat/apache-tomcat-8.5.29/conf/server.xml
找到 Connector port="8080" ,修改成想要的端口并保存
5.启动tomcat
/usr/local/tomcat/apache-tomcat-8.5.29/bin/startup.sh
6.关闭tomcat
./shutdown.sh
7.配置防火墙
