Ubunt 安装相关#

如果是Vmware安装后先禁用intel的一个驱动,否则可能会导致启动失败,系统崩溃#

mount -o remount,rw /
vi /etc/modprobe.d/blacklist.conf


# 在最后添加下面两行

blacklist intel_powerclamp
blacklist i2c_piix4


# 重做引导
update-initramfs -u -k all

#重启后  
lsmod | grep i2c_piix4
# grep不到东西说明就禁用了

设置代理#

• 系统UI网络处设置代理

• 命令行设置代理:

  • gedit  ~/.bashrc
    
    http_proxy=http://yourproxyaddress:proxyport
    export http_proxy
    https_proxy=http://yourproxyaddress:proxyport
    export https_proxy
    
    
    HTTP_PROXY=http://yourproxyaddress:proxyport
    export HTTP_PROXY
    HTTPS_PROXY=http://yourproxyaddress:proxyport
    export HTTPS_PROXY
    
    no_proxy=localhost,127.0.0.0/8,::1,192.0.0.0/8,10.0.0.0/8
    export no_proxy
    
    source ~/.bashrc
      - 
    
    - apt设置代理:
    
      - `sudo gedit /etc/apt/apt.conf.d/10proxy`在您的apt.conf文件中加入下面这行
    
      - ```
        Acquire::http::Proxy “http://proxyusr:password@yourproxyaddress:proxyport”;
        Acquire::ftp::proxy "ftp:/host:port/";
        Acquire::https::proxy "https://host:port/";
    
    

• docker代理设置

  • # ~/.docker/config.json
    
    {
     "proxies":
     {
       "default":
       {
         "httpProxy": "http://192.168.1.12:3128",
         "httpsProxy": "http://192.168.1.12:3128",
         "noProxy": "*.test.example.com,.example2.com,127.0.0.0/8"
       }
     }
    }
    <!--code2-->
    
    

apt加速#

mv /etc/apt/sources.list   /etc/apt/sources.list.bak
sudo rm -rf /var/lib/apt/lists/*

sudo gedit /etc/apt/sources.list


# 访问 https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/   选择版本,复制进来保存



sudo apt-get update

Vmtools#

最简单可行的方法:

sudo apt install open-vm-tools-desktop
sudo reboot

再不行就给虚拟机CD/ROM 加载VMware安装目录下的linux.iso,然后启动后从机器CDROM复制tar包解压到某个目录,执行安装命令
