cobbler安装报错——Exception occured: <class 'cobbler.ce

研究自动化安装cobbler，在进行同步cobbler配置时出现报错

cobbler sync               //同步生成dhcp配置文件

dhcpd -t Failed
Exception occured: <class 'cobbler.cexceptions.CX'>
Exception value: 'cobbler trigger Failed: cobbler.modules.sync_post_restart_services'

看报错是与dhcp服务有关，说明可能是dhcp模板配置错误，进入配置文件中查看，看到果然是地址池配置错误

vi /etc/cobbler/dhcp.template
subnet 192.168.109.0 netmask 255.255.255.0 {
     option routers             192.168.109.1;
     option domain-name-servers 8.8.8.8;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.1.100 192.168.1.254;       //地址池未进行修改
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

subnet 192.168.109.0 netmask 255.255.255.0 {
     option routers             192.168.109.1;
     option domain-name-servers 8.8.8.8;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.109.100 192.168.109.254;               //将地址池做修改
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

注意dhcp模板中要修改的地方：subnet、option routers、dns、range dynamic-bootp

修改后重新加载服务，服务成功！
