006-Cobbler批量自动化部署CentOS/Ubuntu/Windows

这是坚持技术写作计划(含翻译)的第6篇,定个小目标999,每周最少2篇。

本文主要讲解通过CentOS7.6 Minimal + Cobbler 自动化安装CentOS,Ubuntu,Windows

准备

从阿里镜像站,下载 CentOS-7-x86_64-Minimal-1810.iso 和 ubuntu-16.04.5-desktop-amd64.iso ,使用VMware创建一台CentOS7的虚拟机。

环境初始化

1.改为阿里源

# yum源
# 备份系统默认源
[root@localhost ~]# mkdir /etc/yum.repos.d/old && mv /etc/yum.repos.d/C* /etc/yum.repos.d/old/
[root@localhost ~]# yum clean all
# 设置阿里yum源
[root@localhost ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@localhost ~]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

# pip源(2.8.4的bug)
[root@localhost ~]# mkdir ~/.pip
[root@localhost ~]# cat > ~/.pip/pip.conf << EOF
[global]
trusted-host=mirrors.aliyun.com
index-url=https://mirrors.aliyun.com/pypi/simple/
EOF
复制代码

2.配置ssh

默认ssh_config启用了DNS解析,导致每次远程ssh时都特别慢

[root@localhost ~]# sed -i 's%#UseDNS yes%UseDNS no%' /etc/ssh/sshd_config 
复制代码

3.配置SElinux
如果要在Centos上开启Cobbler的支持,需要用root用户运行 setsebool ,注意 -P 参数确保重启仍然生效。
同时需要配置SELinux上下文规则(CentOS 7 Minimal默认不安装 semanage ),用于提供引导镜像。
按照红帽的5.4的教程,设置不生效,所以,禁用SELinux

#//.. setsebool -P httpd_can_network_connect true
#//.. yum provides semanage
#//.. yum -y install policycoreutils-python.x86_64
#//.. semanage fcontext -a -t public_content_t "/var/lib/tftpboot/.*"
[root@localhost ~]# sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config  
[root@localhost ~]# setenforce 0
复制代码

4.配置防火墙

# TFTP
[root@localhost ~]# firewall-cmd --zone=public --add-port=69/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=69/udp --permanent

# HTTPD
[root@localhost ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=443/tcp --permanent

# Cobbler
[root@localhost ~]# firewall-cmd --zone=public --add-port=25150/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=25150/udp --permanent

# Koan 如果未用到,可以不开放
[root@localhost ~]# firewall-cmd --zone=public --add-port=25151/tcp --permanent

# samba window安装需要用到samba,否则可以不开放
[root@localhost ~]# firewall-cmd --zone=public --add-port=139/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=445/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=137/udp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=138/udp --permanent

# 更新防火墙规则
[root@localhost ~]# firewall-cmd --reload

# 查看所有打开的端口
[root@localhost ~]# firewall-cmd --zone=public --list-ports
复制代码

安装Cobbler

安装依赖软件

[root@localhost ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd xinetd
复制代码

设置开机自启动

[root@localhost ~]# systemctl enable httpd
[root@localhost ~]# systemctl enable xinetd
[root@localhost ~]# systemctl enable rsyncd
[root@localhost ~]# systemctl enable tftp
[root@localhost ~]# systemctl enable cobblerd
复制代码

启动服务

[root@localhost ~]# systemctl start httpd
[root@localhost ~]# systemctl start xinetd
[root@localhost ~]# systemctl start tftp
[root@localhost ~]# systemctl start cobblerd
复制代码

检查配置

[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
    https://github.com/cobbler/cobbler/wiki/Selinux
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
5 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.
复制代码

1,2:
cobbler_ip 为cobbler主机ip
next_server 是dhcp主机ip,但是本实验dhcp和cobbler是一台

[root@localhost ~]# export cobbler_ip=192.168.0.12
[root@localhost ~]# sed -i "s%^server: 127.0.0.1%server: ${cobbler_ip}%g" /etc/cobbler/settings
[root@localhost ~]# sed -i "s%^next_server: 127.0.0.1%next_server: ${cobbler_ip}%g" /etc/cobbler/settings
复制代码

3: 可以忽略,因为已经配置SELinux和防火墙了

4:开启tftp功能

[root@localhost ~]# sed -i '/disable\>/s/\<yes\>/no/' /etc/xinetd.d/tftp
复制代码

5:下载bootload

[root@localhost ~]# cobbler get-loaders
复制代码

6:下载ubuntu本地包镜像(不装ubuntu的,可以不用改)

[root@localhost ~]# yum install -y debmirror
[root@localhost ~]# sed -i 's%^@dists="sid"%#@dists="sid"%g;s%@arches="i386"%#@arches="i386"%g' /etc/debmirror.conf
复制代码

7:设置安装系统后的root密码

[root@localhost ~]# export root_pwd=$(openssl passwd -1 -salt `openssl rand 15 -base64` 'Abcd1234!@#$')
[root@localhost ~]# sed -i "s%^default_password_crypted.*%default_password_crypted: \"${root_pwd}\"%g" /etc/cobbler/settings
复制代码

8:电源管理模块(非必选),cman和ence-agents二选一即可,此处忽略

其余修改:

[root@localhost ~]# sed -i "s%manage_dhcp: 0%manage_dhcp: 1%g" /etc/cobbler/settings
[root@localhost ~]# sed -i "s%pxe_just_once: 0%pxe_just_once: 1%g" /etc/cobbler/settings
复制代码

修改dhcp

[root@localhost ~]# vim /etc/cobbler/dhcp.template
\#仅列出修改过的部分
\......
subnet 192.168.0.0 netmask 255.255.255.0 {
     option routers             192.168.0.1;
     option domain-name-servers 192.168.0.1;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.0.100 192.168.0.200;
\......
复制代码

重启服务

[root@localhost ~]# systemctl restart httpd
[root@localhost ~]# systemctl restart xinetd
[root@localhost ~]# systemctl restart tftp
[root@localhost ~]# systemctl restart cobblerd
复制代码

再次校验,发现只有两条信息了,忽略即可。

[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
    https://github.com/cobbler/cobbler/wiki/Selinux
2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.
复制代码

执行 cobbler sync 同步信息

[root@localhost ~]# cobbler sync
task started: 2019-02-22_184309_sync
task started (id=Sync, time=Fri Feb 22 18:43:09 2019)
running pre-sync triggers
# ....忽略
running python trigger cobbler.modules.scm_track
running shell triggers from /var/lib/cobbler/triggers/change/*
*** TASK COMPLETE ***
复制代码

cobbler-web

修复2.8.4 bug

打开 https://${cobbler_ip}/cobbler_web 注意是 https 但是2.8.4有个bug,会导致打开后报500 Internal Server Error 错误 ,是因为  django 版本太高了 (参加 cobbler 2.8.4/2.8.0 on centos 7 error )

[root@localhost ~]# yum install -y python-pip
[root@localhost ~]# pip2.7 install -U django==1.9.13
[root@localhost ~]# systemctl restart cobblerd
复制代码

设置用户名密码

默认用户名密码是 cobbler/cobbler

[root@localhost ~]# htdigest -c /etc/cobbler/users.digest Cobbler cobbler # 后边这个是用户名
[root@localhost ~]# systemctl restart cobblerd
复制代码

再次打开 https://${cobbler_ip}/cobbler_web

挂载镜像

通过 winscp,mobaxterm等将ubuntu和centos镜像上传到Cobbler服务器上的 /tmp/ 目录下,其中 net.ifnames=0 biosdevname=0 noipv6 是让网卡统一命名成 eth0

[root@localhost ~]# mount -t iso9660 -o loop /tmp/CentOS-7-x86_64-Minimal-1810.iso /mnt/
[root@localhost ~]# cobbler import --name=CentOS-7.6.1810-x86_64 --path=/mnt/ --arch=x86_64
[root@localhost ~]# cobbler profile edit --name=CentOS-7.6.1810-x86_64 --kopts='net.ifnames=0 biosdevname=0'
[root@localhost ~]# mount -t iso9660 -o loop /tmp/ubuntu-16.04.5-server-amd64.iso /mnt/
[root@localhost ~]# cobbler import --name=ubuntu-16.04.5-server-x86_64 --path=/mnt/ --arch=x86_64
复制代码

测试PXE安装系统

在vmware创建两个虚拟机(选择空白盘),内存2G,CPU2核,磁盘20G,创建完后,记得打个快照,后边做实验失败后,直接恢复即可。

选择CentOS,然后回车,系统将自动安装

优化配置

CentOS ks

[root@localhost ~]# cobbler profile report --name CentOS-7.6.1810-x86_64
Name                           : CentOS-7.6.1810-x86_64
#//...忽略
Kickstart                      : /var/lib/cobbler/kickstarts/sample_end.ks
#//...忽略
#//复制一份ks,并且进行修改
[root@localhost ~]# cp /var/lib/cobbler/kickstarts/sample_end.ks /var/lib/cobbler/kickstarts/centos-7-6.ks
[root@localhost ~]# cobbler profile edit --name CentOS-7.6.1810-x86_64  --kickstart=/var/lib/cobbler/kickstarts/centos-7-6.ks
[root@localhost ~]# cp /var/lib/cobbler/kickstarts/sample.seed /var/lib/cobbler/kickstarts/ubuntu-16-4-5.seed
[root@localhost ~]# cobbler profile edit --name ubuntu-16.04.5-server-x86_64  --kickstart=/var/lib/cobbler/kickstarts/ubuntu-16-4-5.seed 
复制代码

具体CentOS的ks语法可以参考这里:KICKSTART 语法参考。另外可以参考 运维工作笔记-Cobbler 配置文件
具体Ubuntu的Preseed可以参考这里:Preseed语法参考


吐槽一下,cobbler代码中检测到是ubuntu时,会自动将ks换成url(强制走preseed),而用惯了ks的,用preseed还是很不习惯的,可以看一下 Support selection of automatic installation file format in distros which allow it (Debian/Ubuntu allows kickstart and preseed) 和 Problems Provisioning Ubuntu with Cobbler and Kickstart Profiles
