為了加快網(wǎng)站的解析速度，可以把動(dòng)態(tài)頁(yè)面和靜態(tài)頁(yè)面由不同的服務(wù)器來(lái)解析，加快解析速度。降低原來(lái)單個(gè)服務(wù)器的壓力。 在動(dòng)靜分離的tomcat的時(shí)候比較明顯，因?yàn)閠omcat解析靜態(tài)很慢，其實(shí)這些原理的話(huà)都很好理解，簡(jiǎn)單來(lái)說(shuō)，就是使用正則表達(dá)式匹配過(guò)濾，然后交個(gè)不同的服務(wù)器。

動(dòng)靜分離

實(shí)質(zhì)?：使用正則表達(dá)式，匹配過(guò)濾，交給不同的服務(wù)器

優(yōu)點(diǎn)?：把動(dòng)態(tài)頁(yè)面和靜態(tài)頁(yè)面分別由不同的服務(wù)器來(lái)解析，加快解析速度，降低單個(gè)服務(wù)器的壓力

yum安裝nginx

訪(fǎng)問(wèn)nginx的網(wǎng)站，nginx.org  進(jìn)去找到nginx的yum源
在命令行輸入echo '
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
