章 7. 實​​​作​​​ Kickstart

很​​​明​​​顯​​​的​​​，最​​​適​​​合​​​為​​​一​​​部​​​系​​​統​​​進​​​行​​​配​​​置​​​變​​​更​​​的​​​時​​​機​​​，即​​​為​​​該​​​系​​​統​​​一​​​開​​​始​​​建​​​立​​​時​​​。​​​對​​​於​​​早​​​已​​​有​​​效​​​使​​​用​​​ kickstart 的​​​客​​​戶​​​來​​​說​​​，bootstrapping script 是​​​項​​​作​​​為​​​此​​​程​​​序​​​的​​​理​​​想​​​功​​​能​​​。​​​
一​​​旦​​​所​​​有​​​的​​​配​​​置​​​問​​​題​​​皆​​​解​​​決​​​之​​​後​​​，系​​​統​​​亦​​​可​​​透​​​過​​​使​​​用​​​與​​​ up2date 和​​​ rhn_register RPM 附​​​加​​​在​​​一​​​起​​​的​​​ rhnreg_ks 工​​​具​​​程​​​式​​​，來​​​與​​​本​​​地​​​的​​​ Red Hat Network 伺​​​服​​​器​​​進​​​行​​​註​​​冊​​​。​​​此​​​章​​​節​​​討​​​論​​​了​​​如​​​何​​​正​​​確​​​地​​​使​​​用​​​ rhnreg_ks，以​​​註​​​冊​​​系​​​統​​​。​​​
rhnreg_ks 工​​​具​​​程​​​式​​​使​​​用​​​了​​​啟​​​動​​​金​​​鑰​​​，來​​​一​​​次​​​性​​​地​​​讓​​​系​​​統​​​順​​​利​​​註​​​冊​​​、​​​授​​​予​​​，以​​​及​​​訂​​​閱​​​特​​​定​​​頻​​​道​​​。​​​若​​​要​​​取​​​得​​​更​​​多​​​有​​​關​​​於​​​啟​​​動​​​金​​​鑰​​​的​​​相​​​關​​​資​​​訊​​​，請​​​參​​​閱​​​ Red Hat Network Management 參​​​考​​​指​​​南​​​的​​​ Red Hat Update Agent 與​​​ RHN 的​​​網​​​站​​​章​​​節​​​。​​​
下​​​列​​​註​​​解​​​的​​​ kickstart 檔​​​案​​​，是​​​個​​​如​​​何​​​透​​​過​​​使​​​用​​​ Red Hat Network，以​​​從​​​頭​​​到​​​尾​​​配​​​置​​​系​​​統​​​的​​​理​​​想​​​範​​​本​​​。​​​

( # Note that we run the entire %post section as a subshell for logging.

# Remember that nifty one-line command for the bootstrap script that we
# went through? This is an ideal place for it. And assuming that the
# script has been properly configured, it should prepare the system
# fully for usage of local Red Hat Network Servers.

# The following is an example of the usage of rhnreg_ks, the kickstart
# utility for rhn_register. This demonstrates the usage of the 
# --activationkey flag, which describes an activation key. For example,
# this activation key could be set up in the Web interface to join this 
# system to the "Laptops" group and the local Widgetco "Laptop Software" 
# channel. Note that this section applies only to Proxy users, as this 
# step is handled by the Satellite bootstrap script. 
#
# For more information about activation keys, consult the Red Hat Network
# Management Reference Guide.

# End the subshell and capture any output to a post-install log file.
