让CentOS服务器支持https（安全http协议）

野性酷女 2022-08-06 15:20 194阅读 0赞

我们通常用“http://”这样的方式来访问网站，而此时传输的内容是可能被别人截获的，因为其内容是通过明文传输，所以在传递一些隐私、以及密码相关的信息时，就显得非常的不安全。在一些比较正式的网站、以及一些银行相关的网站中，一些需要提交隐私或者重要级别比较高的密码时，都采用“https://”的方式，来将传输内容加密，从而保证用户安全和避免隐私的泄漏。  
  
今天在这里，我就通过mod\_ssl来使我们的服务器也支持https。（环境：centos 5.5）  
  
**1、安装mod\_ssl  
  
通过yum来在线安装mod\_ssl**  
  
\[root@300second ~\]\# yum -y install mod\_ssl  ← 在线安装mod\_ssl

**2、HTTP 服务器上配置mod\_ssl**  
  
\[1\] 建立服务器密钥  
  
\[root@300second ~\]\# cd /etc/pki/tls/certs/　 ← 进入HTTP服务器配置文件所在目录  
  
\[root@300second certs\]\# make server.key　 ← 建立服务器密钥  
umask 77 ; \\  
/usr/bin/openssl genrsa -des3 1024 > server.key  
Generating RSA private key, 1024 bit long modulus  
................++++++  
......++++++  
e is 65537 (0x10001)  
Enter pass phrase:　 ← 在这里输入口令  
Verifying - Enter pass phrase:　  ← 确认口令，再次输入  
  
\[root@300second certs\]\# openssl rsa -in server.key -out server.key　 ← 从密钥中删除密码（以避免系统启动后被询问口令）  
  
Enter pass phrase for server.key:　  ← 输入口令  
writing RSA key  
  
\[2\] 建立服务器公钥  
  
\[root@300second certs\]\# make server.csr　 ← 建立服务器密钥  
  
umask 77 ; \\  
/usr/bin/openssl req -utf8 -new -key server.key -out server.csr  
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) \[GB\]:CN　  ← 输入国名  
State or Province Name (full name) \[Berkshire\]:Fujian　 ← 输入省名  
Locality Name (eg, city) \[Newbury\]:Quanzhou　  ← 输入城市名

Organizational Unit Name (eg, section) \[\]:　 ← 不输入，直接回车  
Common Name (eg, your name or your server's hostname) \[\]:www.51cto.com　 ← 输入通称（任意）  
Email Address \[\]:300second@163.com 　  ← 输入电子邮箱地址  
  
Please enter the following 'extra' attributes  
to be sent with your certificate request  
A challenge password \[\]:　  ← 不输入，直接回车  
An optional company name \[\]: 　  ← 不输入，直接回车  
  
\[3\] 建立服务器证书

Signature ok  
subject=/C=CN/ST=Fujian/L=Quanzhou/O=www.51cto.com/CN=www.51cto.com/emailAddress=300second@163.com  
Getting Private key  
  
\[root@300second certs\]\# chmod 400 server.\*  ← 修改权限为400  
  
\[4\] 设置SSL  
  
\[root@300second certs\]\# vi /etc/httpd/conf.d/ssl.conf　 ← 修改SSL的设置文件  
  
\#DocumentRoot "/var/www/html"　  ← 找到这一行，将行首的“\#”去掉  
　↓  
DocumentRoot "/var/www/html"　 ← 变为此状态  
  
\[5\] 重新启动HTTP服务，让SSL生效  
  
\[root@300second certs\]\# /etc/rc.d/init.d/httpd restart 　← 重新启动HTTP服务器  
  
停止 httpd: 　　　　　　　　　　　　　 \[ 确定 \]  
启动 httpd:　　　　　　　　　　　　　　\[ 确定\]  
  
**3、测试SSL**  
  
**打开浏览器，在地址栏输入“https://服务器IP地址”或者“https://你的域名”后，如果出现提示安装服务器安全证书的窗口（如下所示），说明服务器已经支持SSL。**
