1.下载tomcat

wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.28/
bin/apache-tomcat-8.5.28.tar.gz

2加压安装

 tar -zxvf apache-tomcat-8.0.33.tar.gz 

3防火墙

iptables -I INPUT -p tcp --dport 8080 -j ACCEPT

4编写防火墙配置文件

vi /etc/sysconfig/iptables

-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT（允许80端口通过防火墙）
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT（允许3306端口通过防火墙）
特别提示：很多网友把这两条规则添加到防火墙配置的最后一行，导致防火墙启动失败，正确的应该是添加到默认的22端口这条规则的下面
添加好之后防火墙规则如下所示：
######################################

-A FORWARD -j REJECT –reject-with icmp-host-prohibited
COMMIT

/etc/init.d/iptables restart      #最后重启防火墙使配置生效
