#上传jdk、tomcat

#安装JDK
rpm -ivh jdk-8u112-linux-x64.rpm
java -version
#设置环境变量
vim /etc/profile.d/java.sh
    #JDK
    JAVA_HOME=/usr/java/jdk1.8.0_112

### 安装tomcat
#Tomcat8官网下载地址：http://tomcat.apache.org/download-80.cgi

#便于测试，可关闭 service iptables stop
sudo iptables -I INPUT -p tcp -m tcp --dport 8080 -j ACCEPT   
sudo /etc/rc.d/init.d/iptables save
sudo service iptables restart
#centos7设置方法
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
