离线安装cobbler

1. 将打包好的cobbler压缩包传入机器（需要手动上传镜像包和离线安装包）

2. 解压offline-cobbler.tar.gz
setenforce 0
systemctl stop firewalld
tar -xvf /tmp/offline-cobbler.tar.gz -C /tmp/

3. 备份现有yum源，需要上传iso镜像
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak

4.编写本地yum源
$ vi /etc/yum.repos.d/cobbler.repo
[cobbler]
name=cobbler local repo
baseurl=file:///tmp/offline-cobbler/
gpgcheck=0
enalbed=1

# 本机镜像源
$ vi /etc/yum.repos.d/Centos.repo
[centos]
name=centos
baseurl=file:///mnt/
gpgcheck=0
enalbed=1

5. 生成yum缓存
yum clean all
yum makecache

6. 安装cobbler
# 关闭selinux和防火墙
# -i 直接修改文件
# s 查找替换
# g 完成所有匹配值的替换
$ sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
$ setenforce 0
$ systemctl disable firewalld.service
$ systemctl stop firewalld.service
# 安装cobbler
$ yum install cobbler -y

7. 移除cobbler yum源之后安装

rm -f /etc/yum.repos.d/cobbler.repo

yum install dhcp httpd -y

8. 启动服务

systemctl enable httpd.service tftp.socket cobblerd.service
systemctl start httpd.service tftp.socket cobblerd.service

9. 检查cobbler

cobbler check

10.自动修复cobbler问题

#!/bin/bash
localIp=192.168.87.204
cp /etc/cobbler/settings{,.bak}
sed -i "s/server: 127.0.0.1/server: $localIp/" /etc/cobbler/settings
# 修改/etc/cobbler/settings文件中的next_server参数的值为提供PXE服务的主机相应的IP地址，如next_server: 192.168.222.129
sed -i "s/next_server: 127.0.0.1/next_server: $localIp/" /etc/cobbler/settings

# 修改/etc/xinetd.d/tftp文件中的disable参数修改为 disable = no
# 备份源文件
cp /etc/xinetd.d/tftp{,.bak}
sed -i 's/disable.*= yes/disable = no/g' /etc/xinetd.d/tftp
# 执行 cobbler get-loaders 命令即可；否则，需要安装syslinux程序包，而后复制/usr/share/syslinux/{pxelinux.,memu.c32}等文件至/var/lib/cobbler/loaders/目录中
#cobbler get-loaders
# 密码加密
newpasswd=`openssl passwd -1 123456`
sed -i s/"default_password_crypted:.*"/"default_password_crypted: "$newpasswd""/g /etc/cobbler/settings

# 配置dhcp服务
cat > /etc/dhcp/dhcpd.conf <<EOF
