1.10. Linux 虚​​​​​​​拟​​​​​​​服​​​​​​​务​​​​​​​器​​​​​​​管​​​​​​​理​​​​​​​图​​​​​​​形​​​​​​​用​​​​​​​户​​​​​​​界​​​​​​​面​​​​​​​

本​​​​​​​节​​​​​​​提​​​​​​​供​​​​​​​对​​​​​​​ Red Hat Cluster Suite 里​​​​​​​可​​​​​​​用​​​​​​​的​​​​​​​ LVS 配​​​​​​​置​​​​​​​工​​​​​​​具​​​​​​​的​​​​​​​概​​​​​​​述​​​​​​​ — Piranha Configuration Tool。​​​​​​​Piranha Configuration Tool 是​​​​​​​一​​​​​​​个​​​​​​​ web 浏​​​​​​​览​​​​​​​器​​​​​​​图​​​​​​​形​​​​​​​用​​​​​​​户​​​​​​​界​​​​​​​面​​​​​​​(GUI),它​​​​​​​提​​​​​​​供​​​​​​​结​​​​​​​构​​​​​​​化​​​​​​​的​​​​​​​方​​​​​​​法​​​​​​​来​​​​​​​创​​​​​​​建​​​​​​​ LVS 配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​ — /etc/sysconfig/ha/lvs.cf。​​​​​​​
要​​​​​​​访​​​​​​​问​​​​​​​ Piranha Configuration Tool,您​​​​​​​需​​​​​​​要​​​​​​​在​​​​​​​活​​​​​​​动​​​​​​​的​​​​​​​ LVS 路​​​​​​​由​​​​​​​器​​​​​​​上​​​​​​​运​​​​​​​行​​​​​​​ piranha-gui 服​​​​​​​务​​​​​​​。​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​在​​​​​​​本​​​​​​​地​​​​​​​访​​​​​​​问​​​​​​​ Piranha Configuration Tool 或​​​​​​​通​​​​​​​过​​​​​​​ web 浏​​​​​​​览​​​​​​​器​​​​​​​进​​​​​​​行​​​​​​​远​​​​​​​程​​​​​​​访​​​​​​​问​​​​​​​。​​​​​​​本​​​​​​​地​​​​​​​访​​​​​​​问​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​使​​​​​​​用​​​​​​​这​​​​​​​个​​​​​​​链​​​​​​​接​​​​​​​: http://localhost:3636。​​​​​​​如​​​​​​​果​​​​​​​要​​​​​​​从​​​​​​​远​​​​​​​程​​​​​​​访​​​​​​​问​​​​​​​,您​​​​​​​可​​​​​​​以​​​​​​​用​​​​​​​主​​​​​​​机​​​​​​​名​​​​​​​或​​​​​​​者​​​​​​​真​​​​​​​实​​​​​​​的​​​​​​​ IP 地​​​​​​​址​​​​​​​后​​​​​​​面​​​​​​​接​​​​​​​着​​​​​​​ :3636。​​​​​​​如​​​​​​​果​​​​​​​您​​​​​​​从​​​​​​​远​​​​​​​程​​​​​​​访​​​​​​​问​​​​​​​ Piranha Configuration Tool,您​​​​​​​需​​​​​​​要​​​​​​​以​​​​​​​根​​​​​​​用​​​​​​​户​​​​​​​身​​​​​​​份​​​​​​​用​​​​​​​ ssh 连​​​​​​​接​​​​​​​活​​​​​​​动​​​​​​​ LVS 路​​​​​​​由​​​​​​​器​​​​​​​。​​​​​​​
Starting the Piranha Configuration Tool causes the Piranha Configuration Tool welcome page to be displayed (refer to 图 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.

下​​​​​​​面​​​​​​​的​​​​​​​内​​​​​​​容​​​​​​​提​​​​​​​供​​​​​​​了​​​​​​​对​​​​​​​ Piranha Configuration Tool 配​​​​​​​置​​​​​​​页​​​​​​​面​​​​​​​的​​​​​​​简​​​​​​​短​​​​​​​描​​​​​​​述​​​​​​​。​​​​​​​

1.10.1. CONTROL/MONITORING

「​​​​​​​CONTROL/MONITORING」​​​​​​​面​​​​​​​板​​​​​​​显​​​​​​​示​​​​​​​运​​​​​​​行​​​​​​​状​​​​​​​态​​​​​​​。​​​​​​​它​​​​​​​显​​​​​​​示​​​​​​​ pulse 守​​​​​​​护​​​​​​​进​​​​​​​程​​​​​​​、​​​​​​​LVS 路​​​​​​​由​​​​​​​表​​​​​​​以​​​​​​​及​​​​​​​ LVS 所​​​​​​​产​​​​​​​生​​​​​​​的​​​​​​​ nanny 进​​​​​​​程​​​​​​​的​​​​​​​状​​​​​​​态​​​​​​​。​​​​​​​

Auto update
让​​​​​​​状​​​​​​​态​​​​​​​显​​​​​​​示​​​​​​​按​​​​​​​照​​​​​​​「​​​​​​​Update frequency in seconds」​​​​​​​文​​​​​​​本​​​​​​​框​​​​​​​里​​​​​​​设​​​​​​​置​​​​​​​时​​​​​​​间​​​​​​​间​​​​​​​隔​​​​​​​(缺​​​​​​​省​​​​​​​为​​​​​​​ 10 秒​​​​​​​)自​​​​​​​动​​​​​​​进​​​​​​​行​​​​​​​更​​​​​​​新​​​​​​​。​​​​​​​
我​​​​​​​们​​​​​​​不​​​​​​​推​​​​​​​荐​​​​​​​将​​​​​​​自​​​​​​​动​​​​​​​更​​​​​​​新​​​​​​​的​​​​​​​时​​​​​​​间​​​​​​​间​​​​​​​隔​​​​​​​设​​​​​​​置​​​​​​​为​​​​​​​少​​​​​​​于​​​​​​​ 10 秒​​​​​​​。​​​​​​​这​​​​​​​样​​​​​​​使​​​​​​​重​​​​​​​新​​​​​​​配​​​​​​​置​​​​​​​「​​​​​​​Auto update」​​​​​​​时​​​​​​​间​​​​​​​间​​​​​​​隔​​​​​​​变​​​​​​​得​​​​​​​困​​​​​​​难​​​​​​​,因​​​​​​​为​​​​​​​页​​​​​​​面​​​​​​​会​​​​​​​过​​​​​​​于​​​​​​​频​​​​​​​繁​​​​​​​地​​​​​​​更​​​​​​​新​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​您​​​​​​​遇​​​​​​​到​​​​​​​这​​​​​​​个​​​​​​​问​​​​​​​题​​​​​​​,只​​​​​​​要​​​​​​​简​​​​​​​单​​​​​​​地​​​​​​​点​​​​​​​击​​​​​​​另​​​​​​​外​​​​​​​一​​​​​​​个​​​​​​​面​​​​​​​板​​​​​​​并​​​​​​​回​​​​​​​到​​​​​​​「​​​​​​​CONTROL/MONITORING」​​​​​​​就​​​​​​​可​​​​​​​以​​​​​​​了​​​​​​​。​​​​​​​
