这一次要做企业网站怎么获得安全的数字证书，没有数字证书的话，在浏览器访问网站的时候会跳出不安全界面，而且钓鱼网站也会让用户进去个假网站，一般企业可以去阿里云去买数字证书，买好之后浏览器便会加载这个数字证书，用户便能安全访问。若出现钓鱼网站，浏览器会检测出来，提醒用户这是个钓鱼网站，不要进入。接下来做一个测试环境的测试，在测试环境下自己可以CA机构，颁发CA证书，操作步骤如下
环境准备：源码安装好了nginx，且已经设置好了nginxctl的控制命令，不知道的可以看之前的文章，做一个脚本，就不需要用绝对路径的方式去启动nginx命令
[root@nginx /]# mkdir certificate #创造一个存放证书的目录
[root@nginx /]# cd certificate/
[root@nginx /]# yum -y install openssl openssl-devel #安装ssl的包，这样就可以生成
证书
[root@nginx certificate]# openssl req #申请颁发数字证书
> -newkey rsa:4096 -nodes -sha256 -keyout ca.key
> -x509 -days 365 -out ca.crt
Generating a 4096 bit RSA private key

writing new private key to 'ca.key'
-----
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]:CN
State or Province Name (full name) []:GD
Locality Name (eg, city) [Default City]:SZ
Organization Name (eg, company) [Default Company Ltd]:QF
Organizational Unit Name (eg, section) []:pycloud
Common Name (eg, your name or your server's hostname) []:www.qffcc.com
Email Address []:1442693983@qq.com
[root@nginx certificate]#openssl req #CA颁发证书，CA机构就会把用户申请的信息加载到存放数字证书的数据库里，跟上述步骤一样就不做演示
> -newkey rsa:4096 -nodes -sha256 -keyout qffcc.com.key
> -out qffcc.com.csr
[root@nginx certificate]#openssl x509 -req -days 365 -in qffcc.com.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out qffcc.com.crt#把签好的证书和密钥发送给浏览器，出现以下结果代表成功
Signature ok
subject=/C=CN/ST=GD/L=SZ/O=QF/OU=qfcloud/CN=www.qffcc.vom/emailAddress=1442693983@qq.com
Getting CA Private Key
[root@nginx certificate]# ls #下面这些文件就是获得证书之后得到的，主要需要qffcc.com.crt qffcc.com.key放到nginx的配置文件里
ca.crt ca.srl -out qffcc.com.csr -x509
ca.key -newkey qffcc.com.crt qffcc.com.key

#上面就已经全部配置完成了，这时候你需要修改mac或者你windows的hosts配置文件，设置域名解析，把虚拟机的nginx服务器的ip 和域名对应上，mac的是在/etc/hosts里。由于它设置了权限，所以需要使用授权，sudo vim /etc/hosts 增加192.168.86.138 www.qffcc.com 保存退出之后，使用本机的浏览器去访问这个www.qffcc.com这个域名就可以访问到了，不过会提示安全问题，强行还是可以进去的。
