1.nginx配置文件

1)上传证书文件到/usr/local/nginx/sslkey/目录下，没有可以自己新建目录。

2)新建nginx.conf，其配置如下：

user  root;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;

    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 16k;
    gzip_http_version 1.1;
    gzip_comp_level 9;
    gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php application/javascript application/json;
    gzip_disable "MSIE [1-6]\.";
    gzip_vary on;


    server {
        listen       80;
        server_name  zomem.com;
        rewrite ^(.*) https://$server_name$1 permanent;

        location /bidu {
            proxy_pass http://127.0.0.1:6000/;
        }
    }


}

其中，

ssl_certificate /usr/local/nginx/sslkey/zomem.com.pem;
ssl_certificate_key /usr/local/nginx/sslkey/zomem.com.key;

是加载ssl证书文件的，路径就是之前上传的地方。

location /api/bidu/ {
    proxy_pass http://127.0.0.1:3000/;
}

是api的地址，服务器对应端口3000，请求地址为:https://zomem.com/api/bidu。

location /bidu {
    proxy_pass http://127.0.0.1:6000/;
}

是文件的地址，对应服务器端口6000，文件地址为:https://file.zomem.com/bidu。

编辑保存后，覆盖服务配置文件：/usr/local/nginx/conf/nginx.conf，然后重启nginx。

2.启动服务器

修改server/.env里面的STATIC_URL=https://file.zomem.com/bidu，以及对应的数据库账号密码等配置，然后将后台项目server里的内容，上传到服务器/root/bidu/server里面，再npm install。
启动服务器后台运行：

cd ~/bidu/server
pm2 start ./bin/www --name biduApi

启动图片服务器：

pm2 serve static 6000 --name biduImg --spa
# 在文件目录static下，启动一个6000端口的服务

这样，cdn的地址https://file.zomem.com/bidu，就会通过nginx转发到本地6000端口的地址了，即static目录。
验证cdn是否成功：直接输入图片地址到浏览器，如https://file.zomem.com/bidu/articles/1.jpg，查看network,如果图片的ip不是服务器ip，说明是用的cdn的ip。如果显示HIT，则是cdn成功了，如果MISS则是失败。

这个时候，在小程序的app.js配置里，换一下对应的接口和图片地址，就可以使用了，之后就是上传审核，然后上线。没想像的那么难吧~哈哈~

/* 更换线上地址 */
/*
config: {
    api: 'http://localhost:3000',
    file: 'http://localhost:3000',
}
*/
config: {
    api: 'https://zomem.com/api/bidu',
    file: 'https://file.zomem.com/bidu',
}

3.系统防火墙问题

如果你在阿里云的后台，开启了80，443端口，还是不能访问，很大可能是centos的系统防火墙没开启这两个端口，可能进行如下操作排查：

查看防火墙状态

firewall-cmd --state

停止firewall

systemctl stop firewalld.service

//临时关闭防火墙,重启后会重新自动打开
systemctl restart firewalld
//检查防火墙状态
firewall-cmd --state
firewall-cmd --list-all
//Disable firewall
systemctl disable firewalld
systemctl stop firewalld
systemctl status firewalld
//Enable firewall
systemctl enable firewalld
systemctl start firewalld
systemctl status firewalld

禁止firewall开机启动

systemctl disable firewalld.service

开启端口(白名单)

firewall-cmd --zone=public --add-port=80/tcp --permanent

命令含义：
--zone #作用域
--add-port=80/tcp #添加端口，格式为：端口/通讯协议
--permanent #永久生效，没有此参数重启后失效

删除白名单

firewall-cmd --permanent --zone=public --remove-port=80/tcp

重启防火墙

firewall-cmd --reload

查新的防火墙规则

firewall-cmd --list-all
