部署Centos7

挂载和导入镜像

mount /dev/cdrom /media

ll /media/

cobbler import --path=/media --name=centos7.4 --arch=x86_64

cobbler distro list                 //查看镜像列表

说明：cobber把镜像导入到该目录下：/var/www/cobbler/ks_mirror/

配置centos7的ks文件

cd /var/lib/cobbler/kickstarts

vim centos7.ks

install

text

keyboard us

lang en_US

timezone Asia/ShangHai

$SNIPPET('cobbler_register')

# Enable post-install boot notification

$SNIPPET('post_anamon')

# Start final steps

$SNIPPET('kickstart_done')

# End final steps

sed -ri "/^#UseDNS/c\UseDNS no" /etc/ssh/sshd_config

sed -ri "/^GSSAPIAuthentication/c\GSSAPIAuthentication no" /etc/ssh/sshd_config

systemctl enable httpd

%end

镜像和ks文件关联

cobbler profile list                    //查看导入的镜像名称,profile包含ks文件和镜像

cobbler profile edit --name=centos7.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7.ks

cobbler profile report

修改C7的网卡为eth0，可以省略

cobbler profile edit --name=centos7.4-x86_64 --kopts='net.ifnames=0 biosdevname=0'

检测ks文件是否有语法错误

cobbler validateks

额外知识：添加一个profile

cp centos7.ks centos7-webserver.ks

cobbler profile add --name=centos7.4-web-server-x86_64 --distro="centos7.4-x86_64" --kickstart=/var/lib/cobbler/kickstarts/centos7.ks  --kopts='net.ifnames=0 biosdevname=0'

cobbler profile report

报错：虚拟机上安装报错：no space left on device，

解决方案虚拟内存不足，调整内存到2G
