nginx 实现动静分离

在生产环境中，nginx的图片相关的静态信息是存放在专用的存储服务器上，然后通过挂载让nginx来读取文件。

server	IP
nginx	172.20.27.10
http1	172.20.27.20
http2	172.20.27.21
nfs	172.20.27.22

---

nginx 服务器做为反向代理来实现动静分离

nginx服务器配置

1.配置反向代理

[[email protected] ~]# mkdir /apps/nginx/conf/servers
[[email protected] ~]# vim /apps/nginx/conf/servers/http_proxy.conf
upstream app 
    server 172.20.27.20:80 weight=1 max_fails=3 fail_timeout=5s;
    server 172.20.27.21:80 weight=1 max_fails=3 fail_timeout=5s;


server 
    server_name www.mylinuxops.com;
    listen 80;
    location / 
        root /data/www;
        index index.html;
    
    location /app 
        proxy_pass http://app;
    
    location ~* \.(gif|jpg|jpeg|bmp|png|tiff|tif|ico|wmf|js)$ 
        root /data/static;
        index index.html;
    

~    

2.将反向代理的配置导入主配置文件

http 
    ......
    include /apps/nginx/conf/servers/*.conf;

3.启动服务

[[email protected] ~]# nginx

apache服务器配置

1.分别在两台服务器上安装httpd并创建站点目录

yum install httpd -y
mkdir /var/www/html/app

2.分别创建测试文件

[[email protected] ~]# echo test1 > /var/www/html/app/index.html

[[email protected] ~]# echo test2 > /var/www/html/app/index.html

3.启动服务

systemctl start httpd

4.在客户端测试反向代理能否使用

[[email protected] ~]# curl www.mylinuxops.com/app/
test1
[[email protected] ~]# curl www.mylinuxops.com/app/
test2

nfs配置

1.创建出需要共享出去的目录

[[email protected] ~]# mkdir /data/static

2.配置nfs文件

[[email protected] ~]# vim /etc/exports
/data/static *(rw,no_root_squash)

3.启动nfs服务

[[email protected] ~]# systemctl start nfs

4.在nginx上挂在nfs文件系统

[[email protected] ~]# vim /etc/fstab 
172.20.27.22:/data/static /data/static  nfs     defaults,_netdev 0 0
#使用nfs挂载时需要加上参数_netdev，否则服务器重启时可能会卡住无法启动
[[email protected] ~]# mount -a
