安装系统

Centos7和Redhat7同版本之间是兼容的，但是不确定Centos7.4和Centos7.7之间是否兼容，而目前国内的源上已经无法下载老版本的Centos7只有最新的CentOS-7-x86_64-DVD-1908.iso或者Centos8。Centos7.4的版本号，我安装的时候选择的是开发版本，

$ uname -a
Linux localhost.localdomain 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

内核

下载对应内核源码3.10.0-693.el7.x86_64，所有包的源码包rpm路径为http://vault.centos.org/centos/7.4.1708/os/Source/SPackages/。
下载Centos8内核源码，https://vault.centos.org/8.3.2011/BaseOS/Source/SPackages/kernel-4.18.0-193.el8.src.rpm

安装，在/root/rpmbuild/SOURCES有一个压缩包linux-4.18.0-240.el8.tar.xz即为内核源码包，

# groupadd mockbuild
# useradd mockbuild -g mockbuild

安装软件

中文输入法
可挂载ntfs格式文件系统

中文输入法用于百度搜索，ntfs挂载后可以把rhel的iso烤出来，下一步配置本地软件源。

$ ./configure
$ make && make install
$ mkdir zc
$ mount -t ntfs-3g /dev/sdb1 ./zc
$ cp rhel-server-7.4-x86_64-dvd.iso  ../
$ mkdir rhel-7.4-yum
$ mount rhel-server-7.4-x86_64-dvd.iso ./rhel-7.4-yum
$ ls /etc/yum.repos.d/
$ sudo mkdir /etc/yum.repos.d/backup
$ sudo mv /etc/yum.repos.d/*.repo backup
$ vim /etc/yum.repos.d/yum.repo
$ cat /etc/yum.repos.d/yum.repo
[centos7.4]
name=centos7.4
baseurl="file:///run/media/qe/CentOS 7 x86_64" #cdrom
gpgcheck=0
$ yum clean all
$ yum makecache
$ yum repolist
$ sudo yum install ftp
$ yum install minicom
$ yum install wireshark
$ yum install wireshark-gnome
$ wireshark

编译驱动，其实下面的已经安装了，

yum install gcc kernel-headers kernel-devel

可直接执行编译，

#ccflags-y += -Wno-error=date-timeifneq ($(KERNELRELEASE),)
obj-m:=pcie_ep.o
else
KERNELDIR:=/lib/modules/`uname -r`/build
PWD:=$(shell pwd)modules:$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
modules_install:$(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install.PHONY: clean
clean:rm -rf *.o *.mod.c *.mod.o *.ko *.order *symvers .*.cmd
endif

网卡驱动从centos7.4迁移到centos7.6报错初始值设置项里有未知的字段ndo_change_mtu，修改ndo_change_mtu为ndo_change_mtu_rh74。

配置阿里源

epel企业源，

# yum install epel-release
# cp bak/CentOS-Linux-PowerTools.repo .
[root@localhost yum.repos.d]# vim CentOS-Linux-PowerTools.repo
# CentOS-Linux-PowerTools.repo
#
# The mirrorlist system uses the connecting IP address of the client and the
# update status of each mirror to pick current mirrors that are geographically
# close to the client.  You should use this for CentOS updates unless you are
# manually picking other mirrors.
#
# If the mirrorlist does not work for you, you can try the commented out
# baseurl line instead.[powertools]

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=PowerTools&infra=$infra

gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

离线安装rpm

rpm -ivh *.rpm

开机自启动

由于/etc/rc.local是/etc/rc.d/rc.local的软连接，所以必须确保/etc/rc.local和/etc/rc.d/rc.local都有可执行权限，

$ ls -l /etc/rc.local
lrwxrwxrwx 1 root root 13  1月 21  2021 /etc/rc.local -> rc.d/rc.local
$ sudo chmod a+x /etc/rc.local
$ sudo chmod a+x /etc/rc.d/rc.local
systemctl enable rc-local
systemctl start rc-local

脚本中所有的路径都必须使用绝对路径，添加[Install]字段，

[storage@localhost ~]$ cat /etc/rc.d/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this#
# In contrast to previous versions due to parallel execution during boot

关闭防火墙

$ firewall-cmd --state
$ systemctl stop firewalld.service

本地源

可以从光盘内copy目录结构，由于我的repomd.xml抱错，使用命令重新建立repo，

$ cp /run/media/qe/CentOS 7 x86_64/* iso
$ creatrepo iso

配置网络

$ sudo vi /etc/sysconfig/network-scripts/ifcfg-enaphyt4i0

# The vncserver service unit file
#
# Quick HowTo:

# 2. Replace <USER> with the actual user name and edit vncserver
#    parameters appropriately
#    (ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
#     PIDFile=/home/<USER>/.vnc/%H%i.pid)
# 3. Run `systemctl daemon-reload`
# 4. Run `systemctl enable vncserver@:<display>.service`
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, you should
# limit connections to the local host and then tunnel from
# the machine you want to view VNC on (host A) to the machine
# whose VNC output you want to view (host B)
#
# [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB
#
# this will open a connection on port 590N of your hostA to hostB's port 590M
# (in fact, it ssh-connects to hostB and then connects to localhost (on hostB).
# See the ssh man page for details on port forwarding)
#
# You can then point a VNC client on hostA at vncdisplay N of localhost and with
# the help of ssh, you end up seeing what hostB makes available on port 590M
#
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
#
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.  See the "-via" option in the
# `man vncviewer' manual page.[Unit]
