让CentOS服务器支持https(安全http协议)

分类:CentOS运维 阅读:77586 次

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。
