让CentOS服务器支持https（安全http协议）,centoshttps在一些比较正式的网站

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

Organization Name (eg, company) [My Company Ltd]:www.51cto.com← 输入组织名（任意）

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

[root@300second certs]#openssl x509 -in server.csr -out server.pem -req -signkey server.key -days 365← 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。
