centos7实战k8s

vm14+CentOS-7-x86_64-DVD-1804.iso，安装的sh时候注意选项，最后选带个桌面感觉稍微好些，不然都是命令行。

/var/run/yum.pid 已被锁定sha\'杀了那个pid完事

先装vmtools把安装包从虚拟磁盘拷贝到当前目录，解压执行

想先装vmtools的，后面发现它要求装gcc/g++

使用yum安装gcc：yum install gcc即可。

使用：which gcc 查看是否安装成功

使用yum安装g++：yum install gcc-c++   即可。

使用：which g++  查看是否安装成功

gdb安装 使用yum安装：yum install gdb即可。

使用：which gdb  查看是否安装成功

Searching for GCC...
Detected GCC binary at \"/bin/gcc\".
The path \"/bin/gcc\" appears to be a valid path to the gcc binary.
Would you like to change it? [no] 
这个安装gcc就行
Searching for a valid kernel header path...
Detected the kernel headers at 
\"/lib/modules/3.10.0-229.4.2.el7.x86_64/build/include\".
The path \"/lib/modules/3.10.0-229.4.2.el7.x86_64/build/include\" appears to be a
valid path to the 3.10.0-229.4.2.el7.x86_64 kernel headers.
Would you like to change it? [no] 

这个我先

我装时INPUT: [/usr/src/kernels/3.10.0-957.1.3.el7.x86_64]要求这个路径

uname -r 显示3.10.0-862.el7.x86_64，第一次运行是空,不知道怎么回事

lixl@localhost ~]$ rpm -qa|grep kernel
kernel-tools-3.10.0-957.1.3.el7.x86_64

综合上面几位来讲确保Kernel、Kernel-devel、Kernel-headers版本一致

检查/usr/src/kernel确实是yum是空就yum -y install kernel-devel 

yum -y update比较靠谱，reboot完

uname -r
3.10.0-957.1.3.el7.x86_64

终于提示ok
