**1**、查看Ubuntu现有的内核版本（），可以看到现在的内核版本是5.0.0

uname -a

![20200110155227347.png][]  
**2**、前往官网[https://www.kernel.org/][https_www.kernel.org]，下载内核源码，我下载的是目前最新版的5.4.10版本

**3**、我将下载到的文件存放在Ubuntu桌面上，如下图

**4**、打开终端进入桌面目录，解压

sudo tar -xavf linux-4.18.14.tar.xz

**5**、安装各种依赖

sudo apt install build-essential 
    sudo apt install gcc 
    sudo apt install make 
    sudo apt install openssl 
    sudo apt install pkg-config 
    sudo apt install libssl-dev 
    sudo apt install libncurses5-dev 
    sudo apt install libc6-dev 
    sudo apt install libelf-dev
    sudo apt install bison
    sudo apt install flex

**6**、进入linux-5.4.10/目录， 准备编译动作：

cd linux-5.4.10/
    sudo cp /boot/config-4.15.0-20-generic .config
    sudo make menuconfig

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hwZjI0Nw_size_16_color_FFFFFF_t_70 2][]  
出现窗口，选择Exit退出（即默认所有选项设置设置）：  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hwZjI0Nw_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hwZjI0Nw_size_16_color_FFFFFF_t_70 4][]

**7**、开始编译：

sudo make
    sudo make modules_install

**8**、进行安装：

cd ..
    sudo mv  linux-5.4.10/  /usr/src/
    cd /usr/src/linux-5.4.10/
    sudo make install
    sudo mkinitramfs -o /boot/initrd.img-5.4.10 
    sudo update-initramfs -c -k 5.4.10				
    sudo update-grub2

**9**、重启后查看内核版本：

sudo shutdown -r now
    uname -a
