CentOS 7 and centos

CentOS 7 and centos
1. Install the 4.1.1 Kernel

1. Install software
Compile and install the new kernel, depending on the development environment and development library
# Yum grouplist // check the installed and uninstalled Software Package groups to determine whether the corresponding development environment and development library are installed;
# Yum groupinstall "Development Tools" // usually install these two software packages. This will ensure that you have all the Tools required for compilation.
# Yum install ncurses-devel // You must execute this command to make * config correctly.
# Yum install qt-devel // if you do not have an X environment, you do not need to use this one.
# Yum install hmaccalc zlib-devel binutils-devel elfutils-libelf-devel

For systems installed in development mode, these packages should be installed.

2 unzip the kernel to the/usr/src/kernels directory and rename it as: linux-4.1.1

The reason is that after the installation is as follows:

ls /usr/lib/modules/4.1.1/build -lhlrwxrwxrwx. 1 root root 28 Jul 10 16:41 /usr/lib/modules/4.1.1/build -> /usr/src/kernels/linux-4.1.1

cp /boot/config-3.10.0-229.7.2.el7.x86_64 ./config<pre name="code" class="python"># sh -c 'yes "" | make oldconfig'

Make oldconfig reads the. config file in the current directory. If no options are found in the. config file, the system prompts the user to fill in. Some documents introduce the use of make memuconfig

Make-j8 bzImage // generate the Kernel File <pre name = "code" class = "python"> make-j4 modules // compile the module make-j4 modules_install // compile and install the module

-The number after j is the number of threads used to speed up compilation. Generally, the logic CPU is used to enter that number. For example, if there is 8 cores, it is-j8. 3. Install the kernel:

# Make install

2. Install the google Browser

First go to the official website to download google-chrome-stable_current_x86_64.rpm

Rpm-ivh installation error lsb> = 4.0

Find the installation method online:

Sudo yum localinstall google-chrome-stable_current_x86_64.rpm

3. Add unofficial sources

http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmhttp://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpmhttp://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

You can directly use yum to install vlc and other software.

4. Delete the old Kernel

Rpm-qa | grep kenrl

Run:

Sudo yum remove kernel-3.10.0-123.8.1.el7.x86_64
Sudo yum remove kernel-devel-3.10.0-123.8.1.el7.x86_64

5. Install google earth

$ cd -$ wget https://dl.google.com/dl/earth/client/current/google-earth-stable_current_x86_64.rpm$ rpm2cpio google-earth-stable_current_x86_64.rpm | cpio -div$ sudo cp -r opt/google/earth /opt/google/$ sudo cp etc/cron.daily/google-earth /etc/cron.daily/$ rm -rf usr opt etc$ sudo ln -s /opt/google/earth/free/googleearth /usr/bin/google-earth

Go to/opt/google/earth/free/googleearth and execute:

sudo cp product_logo_128.png /usr/share/icons/hicolor/128x128/apps/google-earth.pngsudo cp product_logo_16.png /usr/share/icons/hicolor/16x16/apps/google-earth.pngsudo cp product_logo_24.png /usr/share/icons/hicolor/24x24/apps/google-earth.pngsudo cp product_logo_256.png /usr/share/icons/hicolor/256x256/apps/google-earth.pngsudo cp product_logo_32.png /usr/share/icons/hicolor/32x32/apps/google-earth.pngsudo cp product_logo_48.png /usr/share/icons/hicolor/48x48/apps/google-earth.pngsudo cp product_logo_64.png /usr/share/icons/hicolor/64x64/apps/google-earth.pngsudo cp google-earth.desktop /usr/share/applications/

Install the Nvidia driver

To the official website to find a model download: NVIDIA-Linux-x86_64-352.21.run

The location of blacklist. conf is in/usr/lib/modprobe. d/dist-blacklist.conf

Add at the end:

blacklist nouveauoptions nouveau modeset=0

Comment out: # blacklist nvidiafb

Rebuilding initramfs image:

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bakdracut /boot/initramfs-$(uname -r).img $(uname -r)

Systemctl isolate multi-user.target switch to three-mode installation

Check whether nouveau is disabled
Ls mod | grep nouveau

If no relevant content is displayed, it indicates that it is disabled.

Enter the directory where the downloaded driver is located
Chmod + xNVIDIA-Linux-x86_64-352.21.run
/NVIDIA-Linux-x86_64-352.21.run

During installation, Select accept
If you are prompted to modify xorg. conf, select yes

If the resolution is only 800x640 after the restart, You need to modify the resolution.
