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！
