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.keyGenerating 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 key2.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.csrYou are about to be asked to enter information that will be incorporatedinto 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 blankFor 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' attributesto be sent with your certificate requestA 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 oksubject=/C=CN/ST=Xinjiang/L=Shihezi/O=www.51cto.com/emailAddress=xiandian@qq.comGetting Private keyEnter 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 charactersEnter pass phrase for server.key:[root@controller ~]# chmod 400 server.* //修改权限为4004.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ⅤdocumentRoot "/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：
