How to realize the efficient application of HTTPD service and the unified management of resources

High-efficiency application of HTTPD service and integrated resource management for front-end httpd+heepalived plus back-end HEARTBEAT+NFS+DRBD

This article four machines: Centos6.0

LV1, Lv2 Two machines do httpd front-end, use keepalived do high availability, virtual out a VIP for client access.

Node1, Node2 application DRBD technology to achieve file image storage, virtual out a VIP do nfsserver_ip for httpd service, convenient configuration, the unified management of data;

involving applied technology; httpd, keepalived, DRBD, NFS, Heartbeat

As shown in figure:

lv1:192.168.182.130

lv2:192.168.182.129 vip:192.168.182.200 the VIP for client access

node1:192.168.182.133

node2:192.168.182.134 vip:192.168.182.150 The VIP acts as a nfsserver to mount

First shut down the SELinux, iptables; Of course, the real environment is not the case, we do separate configuration can

First, start configuration, LV1, LV2; test front-end is normal

1, respectively implementation: Yum install-y httpd ipvsadm keepalived

In order to separate out LV1, lv2 page differences, respectively, in the page identification Lv1, LV2
