一、简介
二、安装配置

  1. 将Yum源改为国内源并安装EPEL源

    1. 删除/etc/yum.repos.d/目录下的所有文件，

      1. rm -rf /etc/yum.repos.d/*

    2. 新建一个名为Centos-Base.repo的文件，文件内容如下 ```

      CentOS-Base.repo

      #

      The mirror system uses the connecting IP address of the client and the

      update status of each mirror to pick mirrors that are updated to and

      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, as a fall back you can try the

      remarked out baseurl= line instead.

      # #

[base] name=CentOS-$releasever - Base baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/

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

gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

released updates

[updates] name=CentOS-$releasever - Updates baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/updates/$basearch/

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

gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

additional packages that may be useful

[extras] name=CentOS-$releasever - Extras baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/extras/$basearch/

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

gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

additional packages that extend functionality of existing packages

[centosplus] name=CentOS-$releasever - Plus baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/centosplus/$basearch/

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

gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

  2.        c. 清空并重新生成缓存

yum clean all yum makecache

  2. d. 安装epel源
  5. yum -y install httpd dhcp tftp cobbler cobbler-web pykickstart xinetd
  7. systemctl start httpd<br />systemctl start cobblerd
  9. systemctl start cobblerd<br />systemctl stop firewalld<br />setenforce 0<br />vi /etc/sysconfig/selinux  <br />cobbler check
  12. vi /etc/cobbler/settings<br />#修改278行和390行为本地的IP地址
  14. vi /etc/xinetd.d/tftp<br />disable                 = no
  16. cobbler get-loaders
  18. openssl    passwd  -1 -salt 'cobbler' 'cobbler'
  20. vi /etc/cobbler/settings<br />default_password_crypted: "$1$cobbler$M6SE55xZodWc9.vAKLJs6."<br />manage_dhcp: 1  #242行
  22. vi /etc/cobbler/dhcp.template
