    #method=auto
    # 改为手动配置
    method=manual
    # 地址=静态IP/子网掩码，网关
    address=192.168.20.128/24,192.168.20.2
    # dns地址
    dns=114.114.114.114,8.8.8.8
    
    [ipv6]
    addr-gen-mode=eui64
    method=auto

### 5. 关闭防火墙 ###

> 整合nacos2.0.4的时候，服务一直注册不上，耽误了好久，结果把防火墙一关，好家伙，项目直接就跑起来了？？？…后面查了查，说是2.0比1.X新增gRPC通信，多占用9848,9849端口…

> 端口开放相关命令：  
> 开放指定端口：  
> `firewall-cmd --zone=public --add-port=3306/tcp --permanent`  
> `--zone` \# 作用域  
> `--add-port=3306/tcp` \# 添加端口，格式为：端口/通讯协议  
> `--permanent` \# 永久生效，没有此参数重启后失效  
> 查看开放的端口：  
> **cat /etc/firewalld/zones/public.xml**

停止防火墙
    systemctl stop firewalld
    永久关闭防火墙
    systemctl disable firewalld
    防火墙状态
    systemctl status firewalld
