nginx配置CDN和自签名SSL

nginx自签证书

[root@Mike-VM-Node-172_31_225_214 ~]# openssl genrsa -des3 -out tmp.key 2048

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Country Name (2 letter code) [XX]:
State or Province Name (full name) []:
Locality Name (eg, city) [Default City]:
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@Mike-VM-Node-172_31_225_214 ~]# openssl x509 -req -days 365 -in chao.csr -signkey chao.key -out chao.crt

第一步和第二步都需要输入一个自定义密码，然后三四步是替换有密码的证书操作

会得到四个配置文件其中 chao.crt 和 chao.key 两个证书配置到nginx上就可以

   If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save some latency.

虚拟主机配置

https证书配置

其中 172.18.18.50 是后端代理核心ip，这样就可以隐藏真实源ip

不带https证书配置

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]# cat ops.com.conf
upstream ops {
    server 172.18.18.51:80 max_fails=3 fail_timeout=1s weight=1;
}
server {
    listen     80;
    server_name  ops.com;
    #include    conf.d/ops;
    index index.html index.htm index.jsp index.php;
    access_log /data/logs/ops.log upstream2;

    server_tokens off;
    keepalive_timeout   70;

    if ( $query_string ~* ".*[;'<>].*" ){ return 404; }

    location / {
        proxy_pass http://ops;
    }
}
[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]# 

这是不带https的配置，如果域名多可以使用 include 配置到一个文件里写多个域名

nginx反向代理配置

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]# vim abc.com.conf

server
    {
        listen 80;
        server_name abc.com;
        index index.html index.php index.htm default.html default.htm default.php;
        root  /www/wwwtest;


        location ~* .(eot|otf|ttf|woff|woff2|svg)$ {
        add_header Access-Control-Allow-Origin *;
        }


        location /user {
                proxy_set_header Cookie $http_cookie;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr;
                proxy_pass http://127.0.0.1:8080;
   
        }


        location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

        location ~ .*.(js|css)?$
        {
            expires      12h;
        }

        location ~ /.well-known {
            allow all;
        }

        location ~ /.
        {
            deny all;
        }


    }

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]#

这里反向代理的意思是 访问 abc.com/user 域名就是访问  http://127.0.0.1:8080端口的内容

负载均衡

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]# vim test.conf
upstream aaa {
    server 172.18.18.60:80 max_fails=3 fail_timeout=1s weight=1;
    server 172.18.18.61:80 max_fails=3 fail_timeout=1s weight=1;
}

server
    {
        listen 80;
        server_name test.com;
        index index.html index.php index.htm;

  
        location / {
        proxy_set_header Cookie $http_cookie;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_pass http://aaa;
        }


    }

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]#

上面的意思就是    访问 test.com 就是访问 172.18.18.60:80和172.18.18.61:80 里面的内容
