安装好系统之后#xff0c;检查gcc和make是否已经安装

$ apt install gcc
$ apt install mak… ubuntu 18.04网络问题汇总 准备工作一、有线网卡不可用二、无法访问外网 准备工作
安装好系统之后检查gcc和make是否已经安装
$ which gcc
/usr/bin/gcc
$ which make
/usr/bin/make如果未安装则安装gcc和make
$ apt install gcc
$ apt install make安装openssh-server
$ apt install openssh-server安装网络工具和防火墙
$ apt install net-tools
$ apt install ufw开通端口
$ ufw allow 22一、有线网卡不可用
准备设置静态IP时发现没有有线网卡无法正常插网线进行联网。 执行ipconfig 查看网卡配置是否有ethxx或者enxx也没有则说明有线网卡的驱动需要更新。
前往Intel官网下载驱动 , 选择3.8.4版本下载, 然后将下载的软件e1000e-3.8.4.tar.gz通过U盘拷贝到服务器。
解压e1000e-3.8.4.tar.gz安装包文件
$ tar -zxvf e1000e-3.8.4.tar.gz或者
$ gunzip e1000e-3.8.4.tar.gz
$ tar xvf e1000e-3.8.4.ta编译有线网卡驱动
$ cd e1000e-3.8.4/src
$ sudo make
*** disabled for this build.
make[1]: Entering directory /usr/src/linux-headers-4.15.0-142-genericBuilding modules, stage 2.MODPOST 1 modules
make[1]: Leaving directory /usr/src/linux-headers-4.15.0-142-generic安装有线网卡驱动
$ sudo make install
*** The target kernel has CONFIG_MODULE_SIG_ALL enabled, but
*** the signing key cannot be found. Module signing has been
make[1]: Leaving directory /usr/src/linux-headers-4.15.0-142-generic
Running depmod...启用有线网卡启动如果没有报错正常情况下可以看到有线网卡已经正常可用了。
$ sudo modprobe e1000e如果遇到modprobe: ERROR: could not insert ‘e1000e’: Required key not available这是因为从内核4.4.0-20 开始启用EFI_SECURE_BOOT_SIG_ENFORCE编译选项如果启用UEFI Secure Boot将禁止加载未签名的第三方驱动。 重启电脑按ESC进Blos--secuity--secure boot--enabled重新进入系统以太网正常连接。
二、无法访问外网
服务器上部署了docker镜像后调用接口提示无法访问外网去服务器上查看确实无法ping通百度。
$ ping www.baidu.com
ping: www.baidu.com: 未知的名称或服务修改并应用网口信息并重启网络
$ vim /etc/network/interfaces
$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopbackauto eno1
iface eno1 inet static
address 192.168.248.142
gateway 192.168.248.254
netmask 255.255.255.0
dns-nameserver 192.168.42.161
dns-nameserver 8.8.8.8$ netplan apply
$ systemctl restart networking再次ping百度还是不同
$ ping www.baidu.com
ping: www.baidu.com: 未知的名称或服务查看域名解析配置文件发现里面的nameserver和我们的dns配置不一致。
$ cat /etc/resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run systemd-resolve --status to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
nameserver 127.0.0.53
options edns0修改域名解析配置文件如下保存并退出
$ vim /etc/resolv.conf
nameserver 192.168.42.161
options eno1再次ping百度成功。
