Cobbler自动化工具实践

释放双眼,带上耳机,听听看~!

1.Cobbler Install 安装前准备  关闭SELinux

cat /etc/redhat-release
setenforce 0 
getenforce //得到的结果需要是:Permissive

 

如果不是,执行两步:

sed -i \"s#SELINUX=enforcing#SELINUX=disabled#g\" /etc/selinux/config
setenforce 0
reboot

关闭防火墙:

systemctl stop firewalld

开机不启用防火墙:

systemctl disable firewalld

安装wget

yum -y install wget

 

添加一个epel源:

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum -y install cobbler cobbler-web pykickstart httpd dhcp tftp xinetd

 

启动:

systemctl start httpd
systemctl start cobblerd

 

设置cobbler和httpd为开机自启动:

systemctl enable httpd
systemctl enable cobblerd

 

查看cobblerd的启动状态:

netstat -lntup //查看已经启动的端口

检查:

cobbler check

 

对报错进行修复:

vim /etc/cobbler/settings

 

修改 【384行 server: 127.0.0.1为384 server: 本机的ip地址】【272行 next_server: 127.0.0.1为272 next_server: 本机的ip地址】   sed -i \"s#server: 127.0.0.1#server: `ip addr|grep inet|grep brd|awk \'{ print $2 }\'|awk -F/ \'{ print $1 }\'`#g\" /etc/cobbler/settings   2.编辑/etc/xinetd.d/tftp vim /etc/xinetd.d/tftp   修改“    disable                 = yes\"为\"    disable                 = no\" 用sed工具修改: sed -i \'14s/^.*$/    disable            = no/\'  /etc/xinetd.d/tftp   3.执行一条命令: cobbler get-loaders   4.启动rsyncd服务并添加为开机启动项: systemctl start rsyncd.service systemctl enable rsyncd.service   查看启动状态: systemctl status rsyncd.service   systemctl restart xinetd systemctl enable xinetd         5.设置密码: openssl passwd -1 -salt \'cobbler\' \'cobbler\' 执行结果:$1$cobbler$M6SE55xZodWc9.vAKLJs6.   复制此结果到: /etc/cobbler/settings 中       vim /etc/cobbler/settings: 101行 替换 default_password_crypted: \"$1$mF86/UHC$WvcIcX2t6crBz2onWxyac.\" 为 default_password_crypted: \"$1$cobbler$M6SE55xZodWc9.vAKLJs6.\"   sed实现: sed -i \'s#default_password_crypted: \"$1$mF86/UHC$WvcIcX2t6crBz2onWxyac.\"#default_password_crypted: \"$1$cobbler$M6SE55xZodWc9.vAKLJs6.\"#g\' /etc/cobbler/settings   安装其它两个模块: yum -y install fence-agents debmirror   6.重启cobbler服务: systemctl restart cobblerd   7.用cobbler sync同步一下 cobbler sync         再次执行: cobbler check   vim /etc/debmirror.conf   修改@dists=\"sid\";为#@dists=\"sid\"; //*其实就是注释掉这一行 修改@arches=\"i386\";为#@arches=\"i386\";//*其实就是注释掉这一行   sed -i \'s/@dists=\\\"sid\\\";/#@dists=\\\"sid\\\";/g\' /etc/debmirror.conf sed -i \'s/@arches=\\\"i386\\\";/#@arches=\\\"i386\\\";/g\' /etc/debmirror.conf   reboot   systemctl restart cobblerd   systemctl restart httpd   cobbler check   管理dhcp服务: vim /etc/cobbler/settings   修改:242 manage_dhcp: 0为242manage_dhcp: 1 sed -i \'s#manage_dhcp: 0#manage_dhcp: 1#g\' /etc/cobbler/settings   cobbler自带dhcp配置文件: /etc/cobbler/modules.conf   查看dhcp的模板文件: vim /etc/cobbler/dhcp.template   修改部分: subnet 192.168.2.0 netmask 255.255.255.0 {        option routers             192.168.2.1;        option domain-name-servers 8.8.8.8;        option subnet-mask         255.255.255.0;        range dynamic-bootp        192.168.2.100 192.168.2.254;        default-lease-time         21600;        max-lease-time             43200;        next-server                $next_server;   systemctl restart cobblerd   cobbler sync     到此为止:cobbler装完了也配置好了;   distro发行版:centos6/7 1.挂载CentOS7系统ISO光盘 mount /dev/cdrom /mnt/   2.import导入系统镜像 cobbler import --path=/mnt/ --name=CentOS-7-x86-64 --arch=x86_64   --path 镜像路径 --name 安装源定义名称 --arch 制动操作系统平台是32/64位 镜像存放目录,cobbler会将所有的安装文件拷贝到本地一份,放在/var/www/cobbler/ks_mirrors   cobbler profile edit --name=CentOS-7-64-x86_64 --kopts=\'net.ifnames=0 biosdevname=0\'   vim /var/lib/cobbler/kickstarts/centos7-x86-64.cfg   lang en_US keyboard us timezone Asia/Shanghai rootpw --iscrypted $default_password_crypted text install url --url=$tree bootloader --location=mbr zerombr clearpart --all --initlabel part /boot --fstype xfs --size 1024 --ondisk sda part swap --size 16384 --ondisk sda part / --fstype xfs --size 1 --grow  --ondisk sda auth --useshadow --enablemd5 $SNIPPET(\'network_config\') reboot firewall --disabled selinux --disabled skipx   %pre $SNIPPET(\'log_ks_pre\') $SNIPPET(\'kickstart_start\') $SNIPPET(\'pre_install_network_config\') $SNIPPET(\'pre_anamon\') %end   %packages @base @core sysstat iptraf ntp lrzsz ncurses-devel openssl-devel zlib-devel OpenIPMI-tools tree nmap screen %end   %post systemctl disable postfix.service %end   cobbler profile edit --name=CentOS-7-64-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7-x86-64.cfg   cobbler profile report   挂上配置文件 cobbler profile edit --name=CentOS-7-64-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7-x86-64.cfg     再挂载一块Centos6的ISO映像文件 先解除CentOS7的挂载: umount /dev/cdrom   挂载Centos6镜像文件 mount /dev/cdrom /mnt/   import导入系统镜像 cobbler import --path=/mnt/ --name=CentOS-6-x86_64 --arch=x86_64   vim /var/lib/cobbler/kickstarts/centos6-x86_64.cfg   auth --useshadow --enablemd5 bootloader --location=mbr clearpart --all --initlabel part /boot --fstype ext4 --size 1024 --ondisk sda part swap --size 1 --grow --ondisk sda part / --fstype ext4 --size 1 --grow --ondisk sda text firewall --disable firstboot --disable keyboard us lang en_US url --url=$tree $yum_repo_stanza $SNIPPET(\'network_config\') reboot rootpw --iscrypted $default_password_crypted selinux --disabled skipx timezone Asia/Shanghai install   zerombr %packages @base @compat-libraries @debugging @development tree nmap sysstat lrzsz dos2unix telnet %pre $SNIPPET(\'log_ks_pre\') $SNIPPET(\'kickstart_start\') $SNIPPET(\'pre_install_network_config\') $SNIPPET(\'pre_anamon\') %post %end   先查看: cobbler profile list     CentOS-6-64-x86_64    CentOS-7-64-x86_64    所以下面的--name=后面应该写入CentOS-6-64-x86_64   cobbler profile edit --name=CentOS-6-64-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6-x86_64.cfg   systemctl restart dhcpd systemctl enable dhcpd   添加epel源: curl -o /etc/yum.repos.d/epel.repo
http://mirrors.aliyun.com/repo/epel-6.repo yum makecache   Cobbler自定义重装 yum -y install koan   指定重装的系统[先在cobbler服务端用Cobbler profile list查看一下] koan --server=192.168.2.13 --profile=CentOS-7-64-x86_64 --display koan --server=192.168.2.13 --profile=CentOS-7-64-x86_64 --r //koan写入,只有写入后重启才会生效   Cobbler自定义仓库:   1.添加repo: cobbler repo add --name=zabbix3.4 --mirror=
