为了加快网站的解析速度,可以把动态页面和静态页面由不同的服务器来解析,加快解析速度。降低原来单个服务器的压力。 在动静分离的tomcat的时候比较明显,因为tomcat解析静态很慢,其实这些原理的话都很好理解,简单来说,就是使用正则表达式匹配过滤,然后交个不同的服务器。
实质 :使用正则表达式,匹配过滤,交给不同的服务器
优点 :把动态页面和静态页面分别由不同的服务器来解析,加快解析速度,降低单个服务器的压力
静态资源配置(10.36.192.169)
yum安装nginx
- 访问nginx的网站,nginx.org 进去找到nginx的yum源
- 在命令行输入
-
- 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
- module_hotfixes=true
-
- [nginx-mainline]
- name=nginx mainline repo
- baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
- gpgcheck=1
- enabled=0
- gpgkey=https://nginx.org/keys/nginx_signing.key
- module_hotfixes=true ' > /etc/yum.repos.d/nginx.repo
- 清理缓存,生成自己缓存,列出yum仓库
- yum clean all
- yum makecache
- yum repolist
- yum install yum-utils
- yum -y install nginx
- vim /etc/nginx/conf.d/default.conf
- server {
- listen 80;
- server_name localhost;
-
- location ~ \.(html|jpg|png|js|css|gif|bmp|jpeg) {
- root /usr/share/nginx/html;
- }
- }
- nginx -t #检查配置的语法有无问题
- nginx -s reload #重载配置
- rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
- rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
- yum install php71w-xsl php71w php71w-ldap php71w-cli php71w-common php71w-devel php71w-gd php71w-pdo php71w-mysql php71w-mbstring php71w-bcmath php71w-mcrypt -y
- yum install -y php71w-fpm
- systemctl start php-fpm
- systemctl enable php-fpm
yum 安装nginx方法如上
- vim /etc/nginx/conf.d/default.conf
- server {
- listen 80;
- server_name localhost;
- location ~ \.php$ {
- root /usr/local/nginx/html; #指定网站目录
- fastcgi_pass 127.0.0.1:9000; #指定访问地址
- fastcgi_index index.php; #指定默认文件
- fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; #站点根目录,取决于root配置项
- include fastcgi_params; #包含nginx常量定义
- }
- }
- nginx -t
- nginx -s reload
- vim /etc/nginx/conf.d/default.conf
- upstream static {
- server 10.36.192.169 weight=1 max_fails=2 fail_timeout=2s;
- }
- upstream php {
- server 192.168.20.135 weight=2 max_fails=2 fail_timeout=2s;
- }
-
- server {
-
- listen 80;
- server_name localhost;
- location ~ \.php$ {
- proxy_pass http://php;
- proxy_set_header Host $host:$server_port;
- proxy_set_header X-Real-IP $remote_addr;
- proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
- }
- location ~ .*\.(html|gif|jpg|png|bmp|swf|css|js)$ {
- proxy_pass http://static;
- proxy_set_header Host $host:$server_port;
- proxy_set_header X-Real-IP $remote_addr;
- proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-
- }
- }
- nginx -t
- nginx -s reload
当访问静态页面的时候location 匹配到 (html|jpg|png|js|css|gif|bmp|jpeg) 通过转发到静态服务器,静态服务通过location的正则匹配来处理请求。
当访问动态页面时location匹配到 .php 结尾的文件转发到后端php服务处理请求。
