【负载均衡】揭开F5 BIG-IP的神秘面纱(一)

本文涉及的产品
云数据库 RDS MySQL Serverless,0.5-2RCU 50GB
简介:

负载均衡的门槛越来越低,能够制造与生产厂商也越来越多。

 

这里不谈性能评测,只谈实现方式。其实他们的性能越来越接近,差距也在逐渐缩短。

时间服务器:ntpd -u ntp:ntp -p /var/run/ntpd.pid -g

WebAccelerator是apache二次开发: /usr/sbin/httpd -DTrafficShield -DWebAccelerator -DSAM

F5的WEb UI管理界面是一个Tomcat 进程,似乎不是Java写的是Jython写的

 

/usr/lib/jvm/jre/bin/java -Dpython.cachedir=/var/tmp -Djava.library.path=/usr/lib -Xmx120m -classpath :/usr/share/tomcat/bin/bootstrap.jar:/u

 

 

在看看进程的关系
