Ubuntu18.04 修改IP地址、查看网关、防火墙

1. Ubuntu18.04 修改IP地址

因为Ubuntu18.04采用的是netplan来管理network。所以可以在/etc/netplan/目录下创建
一个以yaml结尾的文件。比如01-netplan.yaml文件。

修改 sudo vim /etc/netplan/50-cloud-init.yaml文件

web</a>kit-tab-size:4; tab-size:4; font-size: 13px !important; line-height: 15px !important;">
# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        enp0s3:
            addresses: [192.168.33.34/24]
            gateway4: 192.168.33.1
            dhcp4: no
    version: 2

network:

enp0s3:

addresses: [192.168.33.34/24]

gateway4: 192.168.33.1

dhcp4: no

version: 2

特别要注意的是这里的每一行的空格一定要有的，否则会报错误而设置失败！

运行sudo netplan apply使配置生效，通过ifconfig 查看ip是否配置成功

2. 查看网关

route -n
netstat -r

1 2	route -n netstat -r

3. 防火墙开启/关闭

ufw enable
ufw disable

1 2	ufw enable ufw disable

//下面这个css和插件后台设置的主题有关系，如果需要换样式，则需要修改以下CSS名称
