Lamp+nfs Load Balancing

1. Experimental Requirements:
1) NFS Server Export/data/application/web, in the directory to provide WordPress;
(2) NFS Client Mounts NFS Server exported file system to/var/www/html;
(3) the client (lamp) to deploy WordPress, and let its normal access, to ensure that the normal post, upload pictures;
(4) Client 2 (lamp), Mount NFS server exported file system to/var/www/html, check that its WordPress can be accessed, to ensure that the normal post, upload pictures;

2. Experimental environment:
1) Server Environment
Linux Server OS version: CentOS release 6.7 (Final)
DNS) ip:172.16.66.50
Lamp) ip:172.16.66.60
Lamp) ip:172.16.66.70
NFS) ip:172.16.66.80

2) test environment
WIN7 system client): ip:172.16.66.100

3, the experimental premise:
1) Turn off firewall and SELinux
~]# Service Iptables Stop
~]# sed-i s/selinux=enforcing/selinux=disabled/g/etc/selinux/config

4, the experimental process:



The first part:
Deploying Hosts ip:172.16.66.50
1. Install the DNS server

1.1 Installing the DNS service side
# yum Install Bind-y

1.2 Editing the Master profile/etc/named.conf
Options {
Listen-on Port 53 {172.16.66.50;};
allow-query {localhost;};
Dnssec-enable No;
Dnssec-validation No;

1.3 Edit/etc/named.rfc1912.zones
# sed-n ' 43,46p '/etc/named.rfc1912.zones
Zone "Yang.com" in {
Type master;
File "Yang.com.zone";
};


1.4 Create the corresponding zone resolution library file (the primary record is a or AAAA record) forward
# Cat/var/named/yang.com.zone
$TTL 3600
@ in SOA ns1.yang.com. Dnsadmin.yang.com. (
20160721
1D
10M
3H
)
In NS ns1
NS1 in A 172.16.66.50
www in A 172.16.66.60
WWW1 in CNAME www
www in A 172.16.66.70
WWW2 in CNAME www

1.5 Checking the configuration file for errors
# named-checkconf

Fifth part

1. Testing

1.1 Access a host: 172.16.66.60
http://www.yang.com/wordpress/index.php
