服务器进程依赖关系

服务器进程之间的依赖关系即服务器进程的启动顺序，由管理服务器进程来协调它们之间的启动。假如A依赖于B，那么B应该先启动，如果B尚未启动，那么A应该暂停启动流程，等待B启动。B在启动的时候会通知管理服务器，管理服务器再向A通知B进程已经启动，A收到消息后继续启动流程。

一般来说服务器进程之间的依赖关系(->)如下:

sessionserver -> recordserver

sceneserver -> recordserver, sessionserver, functionserver, mailserver

gatewayserver -> recordserver, sessionserver, sceneserver, functionserver, mailserver

functionserver -> recordserver, sessionserver, mailserver

mailserver -> sessionserver

voiceserver -> sessionserver

spaceserver -> sessionserver

imageserver -> sessionserver

所以启动脚本中启动顺序如下:

server/superserver
sleep 15

server/recordserver
sleep 8

server/sessionserver
sleep 8

server/mailserver
server/spaceserver
sleep 8

server/voiceserver
server/imageserver
sleep 8

server/functionserver
sleep 8

server/sceneserver
sleep 8

server/sceneserver

server/gatewayserver
sleep 5
