年底了写一篇小程序环境搭建的文章, 主要是怎么搭建一个线上环境以及怎么不改动原有http Api的情况

一、程序演示

弄个websocket远程播放音乐的案例

1、准备工作

域名一个

免费证书(推荐: 腾讯云、阿里云、便宜ssl 都是免费的 配置好后先将证书下载下来)

Centos服务器一台

nginx 1.10.2

2、 安装nginx

安装教程

注意安装的时候 编译 --with-stream --with-stream_ssl_module 两个模块

如果启动nginx报错看下图解决

3、 配置nginx实现ssl反向代理

将下载好的证书根据自己的服务器选择证书这里选择nginx证书

主要用到server.crt以及server.key两个证书上传到服务器

这里我们直接上传到nginx目录的conf下了

修改nginx.conf(有注释的地方改 其他的保持原样就行了)

``` #user nobody; 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; 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; server { listen 8090; #这里将原来的80端口改成8090 server_name xxx.xxx.xxx; #这里就写你自己的域名就行了 #charset koi8-r; #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ .php$ { # proxy_pass ; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ .php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} include /usr/nginx/conf/wss.conf;# 这里我们将反向代理新建一个文件引入进来 client_max_body_size 3m;# 上传大小单位M 微信小程序上传大图片时可能需要设置 }  

新建wss.conf

#主要是配置原来的ws 和 http 接口 upstream websocket { server 10.5.11.xxx:8283;# 远程websocket服务器地址 } upstream web{ server ;# 远程http接口 } # 通过下面的反向代理到上面的接口去 server { listen 443;#默认https和wss协议端口 ssl on; ssl_certificate /usr/nginx/conf/server.crt;#你的上传到服务器的证书位置 ssl_certificate_key /usr/nginx/conf/server.key;#你的上传到服务器的证书位置 ssl_session_timeout 5m; ssl_session_cache shared:SSL:50m; ssl_protocols SSLv3 SSLv2 TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; underscores_in_headers on;#开启自定义头信息的下划线 #wss协议转发 小程序里面要访问的链接 location /wss { proxy_pass ;#代理到上面的地址去 proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "Upgrade"; } #https协议转发 小程序里面要访问的链接 location /{ proxy_pass ;#代理到原有的http的地址去 proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; add_header Access-Control-Allow-Origin *;#跨域访问设置 } } ```
