完毕！

HTTP 服务器上配置mod_ssl

1.建立服务器密钥

[root@controller ~]#  cd /etc/pki/tls/certs/　   //进入HTTP服务器配置文件所在目录
[root@controller ~]#  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@controller ~]#  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@controller ~]#  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]:Xinjiang     //输入省名

Locality Name (eg, city) [Newbury]:Shihezi　             //输入城市名

Organization Name (eg, company) [My Company Ltd]:www.msdn.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.msdn.com　 ← 输入通称（任意）

Email Address []:zq@qq.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@controller ~]#  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=Xinjiang/L=Shihezi/O=www.51cto.com/emailAddress=xiandian@qq.com
Getting Private key
Enter pass phrase for server.key:
140645233670048:error:28069065:lib(40):UI_set_result:result too small:ui_lib.c:869:You must type in 4 to 8191 characters
Enter pass phrase for server.key:
[root@controller ~]#  chmod 400 server.*        //修改权限为400

4.设置SSL

[root@controller ~]#  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
Ⅴ
DocumentRoot "/var/www/html"　       //变为此状态

5.重新启动HTTP服务，让SSL生效

[root@controller]#  systemctl restart httpd.service　    //重新启动HTTP服务器

本地配置文件/etc/httpd/conf.d/ssl_saturn.conf：

Listen 443 https
SSLPassPhraseDialog exec:/usr/libexec/httpd-ssl-pass-dialog
SSLSessionCache         shmcb:/run/httpd/sslcache(512000)
SSLSessionCacheTimeout  300
SSLRandomSeed startup file:/dev/urandom  256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin

DocumentRoot "/var/www/html"
ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn
SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5:!SEED:!IDEA
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

    SSLOptions +StdEnvVars

    SSLOptions +StdEnvVars

BrowserMatch "MSIE [2-5]"          nokeepalive ssl-unclean-shutdown          downgrade-1.0 force-response-1.0
CustomLog logs/ssl_request_log           "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

完成 keystone 证书加密的 HTTPS 服务提升
