Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

1.10. Linux 虛​​​​​​​擬​​​​​​​伺​​​​​​​服​​​​​​​器​​​​​​​管​​​​​​​理​​​​​​​圖​​​​​​​形​​​​​​​介​​​​​​​面​​​​​​​

本​​​​​​​節​​​​​​​提​​​​​​​供​​​​​​​了​​​​​​​Red Hat Cluster Suite 的​​​​​​​ LVS 設​​​​​​​定​​​​​​​工​​​​​​​具​​​​​​​之​​​​​​​簡​​​​​​​介​​​​​​​ — Piranha Configuration Tool。​​​​​​​Piranha Configuration Tool 是​​​​​​​網​​​​​​​頁​​​​​​​圖​​​​​​​形​​​​​​​使​​​​​​​用​​​​​​​者​​​​​​​介​​​​​​​面​​​​​​​,提​​​​​​​供​​​​​​​結​​​​​​​構​​​​​​​化​​​​​​​的​​​​​​​方​​​​​​​法​​​​​​​來​​​​​​​建​​​​​​​立​​​​​​​ LVS 的​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​ — /etc/sysconfig/ha/lvs.cf。​​​​​​​
要​​​​​​​存​​​​​​​取​​​​​​​ Piranha Configuration Tool,您​​​​​​​需​​​​​​​要​​​​​​​在​​​​​​​已​​​​​​​啟​​​​​​​用​​​​​​​的​​​​​​​ LVS 路​​​​​​​由​​​​​​​器​​​​​​​上​​​​​​​,執​​​​​​​行​​​​​​​ piranha-gui 服​​​​​​​務​​​​​​​。​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​用​​​​​​​瀏​​​​​​​覽​​​​​​​器​​​​​​​從​​​​​​​本​​​​​​​地​​​​​​​或​​​​​​​遠​​​​​​​端​​​​​​​存​​​​​​​取​​​​​​​ Piranha Configuration Tool。​​​​​​​本​​​​​​​機​​​​​​​的​​​​​​​網​​​​​​​址​​​​​​​是​​​​​​​ http://localhost:3636http://localhost;遠​​​​​​​端​​​​​​​的​​​​​​​則​​​​​​​是​​​​​​​主​​​​​​​機​​​​​​​名​​​​​​​稱​​​​​​​或​​​​​​​實​​​​​​​際​​​​​​​的​​​​​​​ IP 位​​​​​​​址​​​​​​​,之​​​​​​​後​​​​​​​再​​​​​​​加​​​​​​​上​​​​​​​:3636。​​​​​​​如​​​​​​​果​​​​​​​您​​​​​​​想​​​​​​​要​​​​​​​從​​​​​​​遠​​​​​​​端​​​​​​​存​​​​​​​取​​​​​​​ Piranha Configuration Tool,您​​​​​​​需​​​​​​​要​​​​​​​以​​​​​​​ root 身​​​​​​​份​​​​​​​用​​​​​​​ ssh 連​​​​​​​到​​​​​​​已​​​​​​​啟​​​​​​​用​​​​​​​的​​​​​​​ LVS 路​​​​​​​由​​​​​​​器​​​​​​​。​​​​​​​
Starting the Piranha Configuration Tool causes the Piranha Configuration Tool welcome page to be displayed (refer to 圖形 1.29, “The Welcome Panel”). Logging in to the welcome page provides access to the four main screens or panels: CONTROL/MONITORING, GLOBAL SETTINGS, REDUNDANCY, and VIRTUAL SERVERS. In addition, the VIRTUAL SERVERS panel contains four subsections. The CONTROL/MONITORING panel is the first panel displayed after you log in at the welcome screen.

以​​​​​​​下​​​​​​​幾​​​​​​​節​​​​​​​將​​​​​​​簡​​​​​​​述​​​​​​​ Piranha Configuration Tool 設​​​​​​​定​​​​​​​頁​​​​​​​。​​​​​​​

1.10.1. CONTROL/MONITORING

CONTROL/MONITORING(控​​​​​​​制​​​​​​​ / 監​​​​​​​控​​​​​​​)面​​​​​​​板​​​​​​​會​​​​​​​顯​​​​​​​示​​​​​​​執​​​​​​​行​​​​​​​時​​​​​​​的​​​​​​​狀​​​​​​​態​​​​​​​,包​​​​​​​括​​​​​​​ pulse 系​​​​​​​統​​​​​​​程​​​​​​​式​​​​​​​的​​​​​​​狀​​​​​​​態​​​​​​​、​​​​​​​LVS 的​​​​​​​路​​​​​​​由​​​​​​​表​​​​​​​、​​​​​​​以​​​​​​​及​​​​​​​ LVS 衍​​​​​​​生​​​​​​​的​​​​​​​ nanny 程​​​​​​​序​​​​​​​。​​​​​​​

Auto update
讓​​​​​​​狀​​​​​​​態​​​​​​​可​​​​​​​以​​​​​​​自​​​​​​​動​​​​​​​更​​​​​​​新​​​​​​​,更​​​​​​​新​​​​​​​頻​​​​​​​率​​​​​​​是​​​​​​​使​​​​​​​用​​​​​​​者​​​​​​​在​​​​​​​Update frequency in seconds(更​​​​​​​新​​​​​​​頻​​​​​​​率​​​​​​​,單​​​​​​​位​​​​​​​為​​​​​​​秒​​​​​​​)文​​​​​​​字​​​​​​​框​​​​​​​輸​​​​​​​入​​​​​​​的​​​​​​​值​​​​​​​(預​​​​​​​設​​​​​​​值​​​​​​​是​​​​​​​ 10 秒​​​​​​​)。​​​​​​​
我​​​​​​​們​​​​​​​不​​​​​​​建​​​​​​​議​​​​​​​您​​​​​​​把​​​​​​​這​​​​​​​間​​​​​​​隔​​​​​​​設​​​​​​​定​​​​​​​設​​​​​​​成​​​​​​​低​​​​​​​於​​​​​​​十​​​​​​​秒​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​低​​​​​​​於​​​​​​​十​​​​​​​秒​​​​​​​的​​​​​​​話​​​​​​​,頁​​​​​​​面​​​​​​​更​​​​​​​新​​​​​​​會​​​​​​​很​​​​​​​頻​​​​​​​繁​​​​​​​,那​​​​​​​麼​​​​​​​要​​​​​​​再​​​​​​​重​​​​​​​新​​​​​​​設​​​​​​​定​​​​​​​ Auto update 的​​​​​​​間​​​​​​​隔​​​​​​​就​​​​​​​會​​​​​​​有​​​​​​​困​​​​​​​難​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​您​​​​​​​遇​​​​​​​到​​​​​​​這​​​​​​​個​​​​​​​問​​​​​​​題​​​​​​​,只​​​​​​​要​​​​​​​按​​​​​​​下​​​​​​​另​​​​​​​一​​​​​​​個​​​​​​​面​​​​​​​板​​​​​​​,再​​​​​​​回​​​​​​​到​​​​​​​ CONTROL/MONITORING 即​​​​​​​可​​​​​​​。​​​​​​​
