ubuntu装cobbler

 安装cobbler

1、Cobbler 2.9新增uefi支持
2、Cobbler 2.9依赖syslinux 6.x版本支持

apt-get install apache2 libapache2-mod-wsgi python-cheetah python-netaddr python-simplejson python-urlgrabber python-yaml python-django make gcc git automake python-pip
apt-get install tftpd-hpa
apt-get install nasm uuid-dev
wget https://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-6.03.tar.gz
tar zxfv syslinux-6.03.tar.gz
cd syslinux-6.03
pip3 install future distro coverage
make && make install
git clone https://github.com/cobbler/cobbler.git
cd cobbler
pip3 install future distro coverage netaddr simplejson pyyaml Cheetah3
make
make install
ln -s /etc/apache2/conf-available/cobbler.conf /etc/apache2/conf-enabled/
root@ubuntu_18_1:/etc/apache2# cp mods-available/proxy_http.load mods-enabled/
root@ubuntu_18_1:/etc/apache2# cp mods-available/proxy.load mods-enabled/
systemctl start apache2.service
pip3 install netaddr simplejson pyyaml Cheetah3
cp /etc/cobbler/cobblerd.service /lib/systemd/system/cobbler.service
systemctl start cobbler

1.apache启动报错：Invalid command 'ProxyRequests', perhaps misspelled or defined by a module not included in the server configuration

解决方法：必须禁用代理模块。使用以下命令启用它

# a2enmod proxy

2.通过cobbler命令进行环境监测，问题如下：

[root@linux-cobbler ~]# cobbler check
4.1 : 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.
解决办法：
# sed -i 's/server: 127.0.0.1/server: 192.168.56.11/' /etc/cobbler/settings #改为本机的IP地址
或通过vim 打开/etc/cobbler/settings进行修改
4.2 : 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.
解决办法：
# sed -i 's/next_server: 127.0.0.1/next_server: 192.168.56.11/' /etc/cobbler/settings #改为本机的IP地址
或通过vim 更改为本机IP地址
4.3 : change 'disable' to 'no' in /etc/xinetd.d/tftp
解决办法：
# vim /etc/xinetd.d/tftp
将disable = yes 改为disable = no
# systemctl  restart xinetd
4.4 : 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.
解决办法：
# cobbler get-loaders #会下载相关的启动文件 

4.5 : enable and start rsyncd.service with systemctl
解决办法：
# systemctl  enable rsyncd && systemctl  start rsyncd

4.6 : debmirror package is not installed, it will be required to manage debian deployments and repositories  #安装debmirror 包
# yum install debmirror
vim /etc/debmirror.conf #将23和25行注释掉
28 #@dists="sid";
30 #@arches="i386";

4.7 : 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
解决办法：
# openssl passwd -1 -salt "随机短语"  "密码"
# openssl passwd -1 -salt 'suijishu' '123456'
$1$suijishu$pCi13H6xgVMoQBkitx4rg/  #将生成的密码添加到到/etc/cobbler/settings
# vim /etc/cobbler/settings  #替换默认密码
101 default_password_crypted: "$1$suijishu$pCi13H6xgVMoQBkitx4rg/"
[root@linux-node1 ~]# systemctl  restart cobblerd  #更改配置文件要重启服务

4.8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them   #fence设备，电源管理
# yum install cman  fence-agents 

4.9：重启cobblerd再次检查： [root@linux-cobbler ~]# systemctl  restart cobblerd
[root@linux-cobbler ~]# cobbler check
No configuration problems found.  All systems go. #确认检查没有遇到任何问题，如果有问题按照提示处理

a2enmod rewrite
a2enmod proxy
a2enmod python
a2enmod proxy_http
a2enmod proxy_connect
a2enmod wsgi
a2enmod version
