億速云負(fù)載均衡(Cloud Load Balancer)是對(duì)多臺(tái)云服務(wù)器進(jìn)行流量分發(fā)的服務(wù)。億速云負(fù)載均衡可以通過(guò)流量分發(fā)擴(kuò)展應(yīng)用系統(tǒng)對(duì)外的服務(wù)能力，通過(guò)消除單點(diǎn)故障提升應(yīng)用系統(tǒng)的可用性。億速云負(fù)載均衡服務(wù)通過(guò)設(shè)置虛擬服務(wù)地址(VIP)，將位于同一地域的多臺(tái)云服務(wù)器資源虛擬成一個(gè)高性能、高可用的應(yīng)用服務(wù)池。根據(jù)應(yīng)用指定的方式，將來(lái)自客戶(hù)端的網(wǎng)絡(luò)請(qǐng)求分發(fā)到云服務(wù)器池中。億速云負(fù)載均衡服務(wù)會(huì)檢查云服務(wù)器池中云服務(wù)器實(shí)例的健康狀態(tài)，自動(dòng)隔離異常狀態(tài)的實(shí)例，從而解決了云服務(wù)器的單點(diǎn)問(wèn)題，同時(shí)提高了應(yīng)用的整體服務(wù)能力。今天億速云給大家介紹下實(shí)現(xiàn)Web服務(wù)器之間使用同一個(gè)MYSQL和相同的網(wǎng)頁(yè)配置文件的方法
前言：
用NFS、LAMP、BIND結(jié)合的方法，應(yīng)對(duì)網(wǎng)絡(luò)中訪問(wèn)量增大而導(dǎo)致云服務(wù)器負(fù)載運(yùn)行的情況。以實(shí)現(xiàn)Web服務(wù)器之間使用同一個(gè)MYSQL和相同的網(wǎng)頁(yè)配置文件。
實(shí)驗(yàn)環(huán)境：
HostNameIP規(guī)劃
nfs.preferred.com192.168.1.6NFS
ns.preferred.com192.168.1.5
mysql.preferred.com192.168.1.4MYSQL

www.preferred.com192.168.1.2WEB
實(shí)驗(yàn)拓?fù)?#xff1a;
實(shí)驗(yàn)步驟：
一、搭建NFS以下操作在nfs.preferred.com服務(wù)器上實(shí)現(xiàn)[root@localhost?~]#?yum?install?nfs-utils?-y????
[root@localhost?~]#?rpm?-qa?|?grep?nfs-utils?--color
nfs-utils-1.2.3-39.el6.x86_64
創(chuàng)建共享目錄并配置nfs文件[root@localhost~]#?mkdir?/mydata

[root@localhost?~]#?service?rpcbind?start
注：rpcbind是一個(gè)RPC服務(wù)，主要是在nfs共享的時(shí)候負(fù)責(zé)通知客戶(hù)端、服務(wù)器nfs端口號(hào)。

二、搭建DNS以下操作在ns.preferred.com服務(wù)器上實(shí)現(xiàn)[root@localhost?~]#?yum?install?bind?-y?|?tail?-n?5

三、搭建MYSQL以下操作在mysql.preferred.com服務(wù)器上實(shí)現(xiàn)[root@localhost?~]#?mkdir?/mydata/
[root@localhost?~]#?mount?-t?nfs?192.168.1.6:/mydata/?/mydata/????

注：嘗試登陸MYSQL卻報(bào)錯(cuò)，不要緊張。這是因?yàn)?usr/local/bin目錄下確實(shí)mysql導(dǎo)致，只需要建立一個(gè)軟連接即可解決。
