闭关苦炼内功2024-01-27 16:03

date: 2024-01-18, 2024-01-26

原 OS Kernel 3.10

升级至 4.19

1.检查默认内核

  • 检查 vmlinuz 版本

    [root@localhost ~]# grubby --default-kernel
    /boot/vmlinuz-3.10.0-1160.105.1.el7.x86_64
    [root@localhost ~]#

  • 检查 Linux 内核版本

    [root@localhost ~]# uname -a
    Linux localhost.localdomain 3.10.0-1160.105.1.el7.x86_64 #1 SMP Thu Dec 7 15:39:45 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
    [root@localhost ~]#

2.配置 yum 源

  • 备份原 repo 源文件

    [root@localhost ~]# cd /etc/yum.repos.d/
    [root@localhost yum.repos.d]# mkdir bak;mv ./* bak
    mv: cannot move './bak' to a subdirectory of itself, 'bak/bak'
    [root@localhost yum.repos.d]# ll
    total 0
    drwxr-xr-x 2 root root 220 Jan 25 20:24 bak
    [root@localhost yum.repos.d]#

  • 下载阿里云 CentOS7 repo 源

    [root@localhost yum.repos.d]# curl -o CentOS-Ali.repo https://mirrors.aliyun.com/repo/Centos-7.repo
    % Total % Received % Xferd Average Speed Time Time Time Current
    Dload Upload Total Spent Left Speed
    100 2523 100 2523 0 0 2789 0 --:--:-- --:--:-- --:--:-- 2787
    [root@localhost yum.repos.d]#
    [root@localhost yum.repos.d]# ll
    total 4
    drwxr-xr-x 2 root root 220 Jan 25 20:24 bak
    -rw-r--r-- 1 root root 2523 Jan 25 20:25 CentOS-Ali.repo
    [root@localhost yum.repos.d]#

  • 更新本地 repo 源

    [root@localhost yum.repos.d]# yum clean all
    [root@localhost yum.repos.d]# yum makecache fast
    Loaded plugins: fastestmirror
    Repository base is listed more than once in the configuration
    Repository updates is listed more than once in the configuration

    updates | 2.9 kB 00:00:00
    Metadata Cache Created
    [root@localhost ~]#

  • 查看 repo 源

    [root@localhost ~]# yum repolist

3.下载内核离线包

复制代码 
cd /opt
wget http://193.49.22.109/elrepo/kernel/el7/x86_64/RPMS/kernel-ml-4.19.12-1.el7.elrepo.x86_64.rpm
wget http://193.49.22.109/elrepo/kernel/el7/x86_64/RPMS/kernel-ml-devel-4.19.12-1.el7.elrepo.x86_64.rpm

4.安装内核

复制代码 
[root@localhost ~]# cd /opt/
[root@localhost opt]# ll

[root@localhost opt]#

5.更改内核启动顺序

复制代码 
[root@localhost ~]# grub2-set-default 0
[root@localhost ~]# grub2-mkconfig -o /etc/grub2.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-4.19.12-1.el7.elrepo.x86_64

done
[root@localhost ~]#
[root@localhost ~]# grubby --args="user_namespace.enable=1" --update-kernel="$(grubby --default-kernel)"
[root@localhost ~]#

6.检查内核版本

复制代码 
[root@localhost ~]# grubby --default-kernel
/boot/vmlinuz-4.19.12-1.el7.elrepo.x86_64
[root@localhost ~]#

7.重启

复制代码 
[root@localhost ~]# reboot

8.再次检查内核版本

复制代码 
[root@localhost ~]# uname -a
Linux localhost.localdomain 4.19.12-1.el7.elrepo.x86_64 #1 SMP Fri Dec 21 11:06:36 EST 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]#

9.修改启动界面显示的内核顺序

  • 注释掉 3.10 内核

    [root@localhost ~]# vim /etc/grub2.cfg
