定制centos7.7安装镜像默认内核5.5去除默认3.10内核
nanshan 2024-10-13 03:48 23 浏览 0 评论
镜像定制内容：
- 定制镜像内容
- 基于官方镜像minimal版定制
- 禁用自带的 nouveau nvidia驱动(Linux安装显卡驱动免重启即时生效),为自动化部署脚本提供便携.
检查方式:
[root@localhost ~]# cat /etc/modprobe.d/blacklist.conf
blacklist nouveau
[root@localhost ~]#
- 内置5.5.7-1.el7.elrepo.x86_64 内核,去除官方默认自带3.10.0-957.el7.x86_64内核.
- 内置ntfs-3g插件(支持直接插ntfs格式的u盘拷贝)
- 以内置以下常用命令/开发调试工具包
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
优化Centos系统
- 更换yum源默认为 阿里源，增加docker-ce国内源CentOS-Base.repo docker-ce.repo epel.repo
- /etc/rc.local默认给执行权限
- 优化sshd----------->>> UseDNS no
- 关闭firewalld防火墙
- 关闭Selinux开机自启
- 默认开启命令行tab键补齐功能
- 内核参数优化如下
准备环境
yum install createrepo genisoimage -y第一：准备完整的安装镜像CentOS-7，挂载到虚拟机，并同时创建一个用于编辑存放的目录centos7
mkdir -p /home/centos7
mount /dev/cdrom /mnt
cd /mnt && ls -l第二：复制光盘文件到可编辑目录centos7
cp -rfv /mnt/* /home/centos7 第三：编辑bios引导文件
[root@localhost ~]# cat /home/centos7/isolinux/isolinux.cfg
