nginx配置ssl验证

在上一篇博客中，我们只是通过nginx搭建了反向代理服务，由于需要在小程序中使用https服务，所以需要申请安全证书。

1.在所购买的域名商那申请免费的ssl证书，我买的是阿里的，所以直接在阿里上申请，并下载下来。具体申请方法可以参考：https://yq.aliyun.com/articles/637307，https://yq.aliyun.com/articles/641517?spm=a2c4e.11153940.blogcont637307.20.577e259d9An8Dk。

2.下载ssl的时候选择nginx，下载后解压会看到一个.key和.pem的文件，然后在服务器/etc/nginx/目录下，创建ssl文件夹，然后将这两个文件放入。

3.在nginx.conf中配置，一般默认会在/etc/nginx/nginx.conf，配置如下：

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;

        }
server{
                listen 80;
                server_name xxxxx.com;
                rewrite ^(.*)$ https://$host$1 permanent; # 把http的域名请求转成https

        }
}
#mail {
#       # See sample authentication script at:
#       # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
#       # auth_http localhost/auth.php;
#       # pop3_capabilities "TOP" "USER";
#       # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
#       server {
#               listen     localhost:110;
#               protocol   pop3;
#               proxy      on;
#       }
#
#       server {
#               listen     localhost:143;
#               protocol   imap;
#               proxy      on;
#       }
#}

这样配置就成功，小程序就可以正常访问了。
