新聞資訊

    像定制內容：

    • 定制鏡像內容
    • 基于官方鏡像minimal版定制
    • 禁用自帶的 nouveau nvidia驅動(Linux安裝顯卡驅動免重啟即時生效),為自動化部署腳本提供便攜.

    檢查方式:

    [root@localhost ~]# cat /etc/modprobe.d/blacklist.conf

    blacklist nouveau

    [root@localhost ~]#

    • 內置5.5.7-1.el7.elrepo.x86_64 內核,去除官方默認自帶3.10.0-957.el7.x86_64內核.
    • 內置ntfs-3g插件(支持直接插ntfs格式的u盤拷貝)
    • 以內置以下常用命令/開發(fā)調試工具包

    telnet,lrzsz,htop,iftop,git,vim,tree,wget,gcc-c++,openssl-devel,expect,rpm,ntpdate,nmap-ncat,net-tools,unzip,yum-utils,device-mapper-persistent-data,bash-completion,bash-completion-extras,libcurl,openssl,ncurses-devel,gcc,kernel-ml,kernel-ml-devel,kernel-ml-headers,kernel-ml-tools-libs,kernel-ml-tool,kernel-ml-tools-libs-devel

    優(yōu)化Centos系統(tǒng)

    1. 更換yum源默認為 阿里源，增加docker-ce國內源CentOS-Base.repo docker-ce.repo epel.repo
    2. /etc/rc.local默認給執(zhí)行權限
    3. 優(yōu)化sshd----------->>> UseDNS no
    4. 關閉firewalld防火墻
    5. 關閉Selinux開機自啟
    6. 默認開啟命令行tab鍵補齊功能
    7. 內核參數優(yōu)化如下


    準備環(huán)境

    yum install  createrepo  genisoimage   -y

    第一：準備完整的安裝鏡像CentOS-7，掛載到虛擬機，并同時創(chuàng)建一個用于編輯存放的目錄centos7

    	mkdir -p /home/centos7
	mount /dev/cdrom /mnt
	
	cd /mnt && ls -l

    第二：復制光盤文件到可編輯目錄centos7

    cp -rfv /mnt/* /home/centos7

    第三：編輯bios引導文件

    [root@localhost ~]# cat  /home/centos7/isolinux/isolinux.cfg

    第六：把準備好的 rpm包拷貝到/home/centos7/Packages/

    提取rpm包不下載用以下命令

    yum install --downloadonly    wget
find  /var/cache/  -name  "*.rpm"  -exec  \cp -av  {}  /root/kernel-5.5/  \;
    
\cp -rav /root/kernel-5.5/*  /home/centos7/Packages/

    第六：生成iso鏡像,在當前目錄下

    cd /home/centos7/
createrepo  -g  comps.xml   ./
genisoimage -joliet-long -V CentOS7 -o CentOS-7.7-kernel-5.5.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -cache-inodes -T -eltorito-alt-boot -e images/efiboot.img -no-emul-boot /home/centos7


    效果

    PXE-E61：Media test failure, check cable

    PXE-M0F：Exiting Intel Boot Agent.

    翻譯：

    PXE-E61：介質測試失敗，檢查電纜

    PXE-M0F：退出英特爾啟動代理。


    嘗試以下方法：

    1、測試網線水晶頭是否正常，對換網線水晶頭測試；

    2、開機時拔掉手機的USB連接線；

    3、開機時拔掉USB存儲設備，比如U盤；

    4、桌面開關USB口、USB鍵鼠和USB耳機故障也會引起；

    5、重置BIOS默認設置，重新配置網絡PXE IPV4啟動，或者更改為UEFI PXE啟動模式；

    6、網卡PNP使用當前最新，關閉網卡節(jié)能環(huán)保選項；

    7、云更新無盤系統(tǒng)編輯有問題客戶機列表，修改傳輸模式UDP；


    有其他解決方法請留言分享，謝謝
