export JRE_HOME=/usr/local/java/jdk1.8/jre

systemctl start tomcat

使tomcat开机启动

tomcat的默认端口是8080

开启Tomcat默认的8080端口
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --reload

vim /usr/local/nginx/conf/nginx.conf

修改nginx配置文件

把80端口映射到8080端口

添加

location /tomcat/ {
        proxy_pass http://127.0.0.1:8080/;
}

systemctl restart nginx

重启nginx
