by Hi, Dear Joern Staudt
Thank you for your kindness help .
According to your suggestion, I should divide my Question
into two parts :
1. repllicates data to various servers
A. for Static content for web request
Yes , IF Apache runs as NFS client to access the data on NFS
Server, there will be a bottleneck problem. For every user hits will
leads to 2 requests , 1 from user to apache server, 2 from apache
server to nfs server, agree ? I have thought of using reverse proxy
caching server (Squid) to solve the problem, this can reduce the
requests , right ? but how to acheive it using Squid ? i just can use
ipmasqadm to redirect the request to my squid port , have no idea to
any further solution on squid , can you help me ?
B. for dynamic data generated by CGI or Script
using Reverse Proxy is not a good solution, right ? any
better solutions ?
2. Request Distribution
using Round-robin DNS query is no what i want , because it only
randomly deliver data request not according to the weight of web
server , that is , intelligent distribution. if using ipmasqadm to
redirect the request to serveral internal web servers , how can i
change the rules in ipmasqadm accroding to the weight of web server ?
that is , how let one web server automatically reponse user click when
she know that the weight of another one's is overload ? which software
can i use to monitor the performance of web servers ?
i just told i can use lvs daemon ("linux vitual server") to acheive
it , is it right ?
maybe i asked too lot , but i do need your great help .
Thank you , thanks a lot
