微信小程序开发在Centos 6.8下使用letsencrypt.sh脚本为nginx设置免费https证书步骤

wx.request(OBJECT)

wx.request发起的是 HTTPS 请求。

于是开始了在Centos 6.8下利用letsencrypt.sh脚本为nginx 配置免费https（Let's Encrypt SSL证书）的路程。

1、下载letsencrypt.sh

# wget https://raw.githubusercontent.com/xdtianyu/scripts/master/lets-encrypt/letsencrypt.conf
# wget https://raw.githubusercontent.com/xdtianyu/scripts/master/lets-encrypt/letsencrypt.sh

2、修改letsencrypt.conf文件的参数

# vim letsencrypt.conf
 
# only modify the values, key files will be generated automaticly.
ACCOUNT_KEY="letsencrypt-account.key" 
DOMAIN_KEY="mtian.net.key"
DOMAIN_DIR="/usr/local/nginx/html"  #网站的根目录
DOMAINS="DNS:mtian.net,DNS:www.mtian.net" #你的网站域名，多个域名用,号分隔
#ECC=TRUE
#LIGHTTPD=TRUE

3、执行文件，生成https所需要的ssl证书文件

添加执行权限并执行
# chmod +x letsencrypt.sh   
# ./letsencrypt.sh letsencrypt.conf  
 
运行完成后会在当前目录生成如下文件
letsencrypt-account.key  lets-encrypt-x3-cross-signed.pem  mtian.csr
letsencrypt.conf         mtian.chained.crt                 mtian.net.key
letsencrypt.sh           mtian.crt

5、修改nginx配置文件，加入https

# vim /usr/local/nginx/conf/nginx.conf
 
 
    
    server {
        listen       443 ssl;
        server_name  www.mtian.net;
 
        ssl on;
         
        ssl_certificate /usr/local/nginx/conf/mtian.chained.crt;
        ssl_certificate_key /usr/local/nginx/conf/mtian.net.key;
 
 
        location / {
            root   html;
            index  index.html index.htm;
        }
    }

6、复制letsencrypt.sh生成的mtian.chained.crt和mtian.net.key 件到 nginx.conf中指定的目录/usr/local/nginx/conf/

# cp  mtian.chained.crt /usr/local/nginx/conf/
# cp  mtian.net.key  /usr/local/nginx/conf/

7、重启nginx

# service nginx restart
 
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]

8、打开浏览器访问https://www.mtian.net/，火狐和谷歌都可以正常访问并且有绿色的锁，https配置完成。
