linux 升级系统内核

一、下载linux内核安装包

这里下载的是linux-4.10版本的内核

下载地址：https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.10.tar.gz

wget -O /usr/local/src/linux-4.10.tar.gz ' https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.10.tar.gz'--no-check-certificate

二、安装内核

yum -y install openldap openldap-clients openldap-developenldap-servers gcc gcc-c++ glibc automake autoconf libtool makelibmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpnglibpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-develglibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-develcurl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-developenssl openssl-devel

 

tar -zxf /usr/local/src/linux-4.10.tar.gz -C/usr/src/kernels/

cd /usr/src/kernels/linux-4.10/

 

#配置内核并安装

make mrproper                        #清除环境变量，即清除配置文件

make menuconfig                     #在菜单模式下选择需要编译的内核模块

 

make                 #约50分钟

make all

make modules_install

make install

三、修改内核配置

sed -i '/^default=/c\default=0' /boot/grub/grub.conf

sed -i '/^default=/c\default=0' /etc/grub.conf

四、重启系统

reboot

五、检查系统内核

uname-r

4.10.0
