1. 更新yum，并且更换阿里镜像源

删除yum文件
cd /etc/yum.repos.d/    进入yum核心目录
ls
sun.repo
rm -rf *    删除之前配置的本地源
ls
配置阿里镜像源
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
配置扩展包
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

2. 安装jdk8

检索jdk列表
yum list | grep jdk

选择合适的安装
yum install java-1.8.0-openjdk-devel.x86_64

验证
java -version

3. 安装宝塔（centos安装脚本）

yum install -y wget && wget -O install.sh https://download.bt.cn/install/install_6.0.sh && sh install.sh ed8484bec

4. 使用宝塔安装mysql、redis、kafka、nacos、nginx
mysql、redis、kafka、nacos统统不开放外网访问
5. 配置nginx转发mysql、redis、kafka、nacos
   这里的mysql、redis、kafka与nacos有所不同
   mysql等服务是tcp协议，而nacos是使用的http协议

        }
    }
    
include /www/server/panel/vhost/nginx/*.conf;
}

6. 调整kafka配置
   这样配置是可以将kafka转发到nginx的11007端口
   但是在消费的时候会提示连接断开或者无法获取连接
   修改kafka配置文件
   listeners配置kafka服务的地址
   advertised.listeners配置nginx转发的地址

listeners=PLAINTEXT://127.0.0.1:9092
# 外部代理地址                                
advertised.listeners=PLAINTEXT://127.0.0.1:11007

7. 编写生产者和消费者测试
   

补充：有条件的可以把nginx放在公网即可，并且可以利用nginx限制ip
