# Linux Kernel 升级 | ||
|
||
k8s,docker,cilium等很多功能、特性需要较新的linux内核支持,所以有必要在集群部署前对内核进行升级;CentOS7 和 Ubuntu16.04可以很方便的完成内核升级。 | ||
|
||
## CentOS7 | ||
|
||
``` bash | ||
# 载入公钥 | ||
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org | ||
# 安装ELRepo | ||
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm | ||
# 载入elrepo-kernel元数据 | ||
yum --disablerepo=\* --enablerepo=elrepo-kernel repolist | ||
# 查看可用的rpm包 | ||
yum --disablerepo=\* --enablerepo=elrepo-kernel list kernel* | ||
# 安装最新版本的kernel | ||
yum --disablerepo=\* --enablerepo=elrepo-kernel install -y kernel-ml.x86_64 | ||
# 删除旧版本工具包 | ||
yum remove kernel-tools-libs.x86_64 kernel-tools.x86_64 -y | ||
# 安装新版本工具包 | ||
yum --disablerepo=\* --enablerepo=elrepo-kernel install -y kernel-ml-tools.x86_64 | ||
|
||
#查看默认启动顺序 | ||
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg | ||
CentOS Linux (4.4.4-1.el7.elrepo.x86_64) 7 (Core) | ||
CentOS Linux (3.10.0-327.10.1.el7.x86_64) 7 (Core) | ||
CentOS Linux (0-rescue-c52097a1078c403da03b8eddeac5080b) 7 (Core) | ||
#默认启动的顺序是从0开始,新内核是从头插入(目前位置在0,而4.4.4的是在1),所以需要选择0。 | ||
grub2-set-default 0 | ||
#重启并检查 | ||
reboot | ||
``` | ||
|
||
## Ubuntu16.04 | ||
|
||
``` bash | ||
打开 http://kernel.ubuntu.com/~kernel-ppa/mainline/ 并选择列表中选择你需要的版本(以4.16.3为例)。 | ||
接下来,根据你的系统架构下载 如下.deb 文件: | ||
Build for amd64 succeeded (see BUILD.LOG.amd64): | ||
linux-headers-4.16.3-041603_4.16.3-041603.201804190730_all.deb | ||
linux-headers-4.16.3-041603-generic_4.16.3-041603.201804190730_amd64.deb | ||
linux-image-4.16.3-041603-generic_4.16.3-041603.201804190730_amd64.deb | ||
#安装后重启即可 | ||
$ sudo dpkg -i *.deb | ||
``` |
