篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Linux应用:配制SSL站点相关的知识,希望对你有一定的参考价值。

配制一个SSL站点

1、自建CA签证服务器IP:192.168.1.5  电脑名称:jacktest (Linux5.4-32b)

2、http服务器IP:192.168.1.3  电脑名称:test (Linux5.4-32b)

3、测试服务器IP:  192.168.1.19  电脑名称:test2 (winXP)

4、站点名称与证书站点名称一定要一致,否则有警告;

5、一个IP地址只能建立一个SSL虚拟主机;


一、安装SSL环境

[[email protected] conf.d]# yum install mod_ssl

Installed:
  mod_ssl.i386 1:2.2.3-31.el5
Dependency Installed:
  distcache.i386 0:1.4.5-14.1

[[email protected] conf.d]# rpm -ql mod_ssl
/etc/httpd/conf.d/ssl.conf         #ssl配制文件
/usr/lib/httpd/modules/mod_ssl.so  #ssl模块
/var/cache/mod_ssl         #ssl缓存目录
/var/cache/mod_ssl/scache.dir
/var/cache/mod_ssl/scache.pag
/var/cache/mod_ssl/scache.sem


二、设置CA服务器

[[email protected] ~]# cd /etc/pki/CA   #CA服务器192.168.1.5
[[email protected] CA]# (umask 077; openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
......+++
........................................................................................+++
e is 65537 (0x10001)
[[email protected] CA]# ll private/
total 4
-rw------- 1 root root 1679 Dec 28 08:56 cakey.pem
[[email protected] CA]#  vi ../tls/openssl.cnf

[ CA_default ]
dir        = /etc/pki/CA   # Where everything is kept

certs      = $dir/certs    # Where the issued certs are kept签发的证书位置
crl_dir    = $dir/crl     # Where the issued crl are kept吊销的证书位置
database   = $dir/index.txt    # database index file颁发过的证书索引文件
#unique_subject = no      # Set to ‘no‘ to allow creation of
         # several ctificates with same subject.
new_certs_dir   = $dir/newcerts   # default place for new certs.

certificate   = $dir/cacert.pem   # The CA certificate指明CA的自签证书
serial  = $dir/serial  # The current serial number 指明当前证书序列号,第一次要指定

...

[ req_distinguished_name ]
countryName        = Country Name (2 letter code)
countryName_default     = CN
countryName_min      = 2
countryName_max     = 2

stateOrProvinceName    = State or Province Name (full name)
stateOrProvinceName_default     = Jiansu

localityName       = Locality Name (eg, city)
localityName_default         = Suzhou

0.organizationName    = Organization Name (eg, company)
0.organizationName_default      = jacktest

# we can do this but it is not needed normally :-)
#1.organizationName       = Second Organization Name (eg, company)
#1.organizationName_default    = World Wide Web Pty Ltd

organizationalUnitName    = Organizational Unit Name (eg, section)
#organizationalUnitName_default =
organizationalUnitName_default  = Tech

[[email protected] CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3655 
You are about to be asked to enter information that will be incorporated  #生成自签证书
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) [CN]:
State or Province Name (full name) [Jiansu]:
Locality Name (eg, city) [Suzhou]:
Organization Name (eg, company) [jacktest]:
Organizational Unit Name (eg, section) [Tech]:
Common Name (eg, your name or your server‘s hostname) []:ca.jacktest.com

[[email protected] CA]# mkdir certs crl newcerts
[[email protected] CA]# touch index.txt
[[email protected] CA]# echo 01 > serial
[[email protected] CA]# ls
certs  crl  index.txt  newcerts  private  serial


三、设置服务器申请证书

[[email protected] ssl]# (umask 077; openssl genrsa 1024 > httpd.key)
Generating RSA private key, 1024 bit long modulus
.....................................................++++++
....................................++++++
e is 65537 (0x10001)
[[email protected] ssl]# ll
total 8
-rw------- 1 root root  887 Dec 28 09:40 httpd.key

[[email protected] ssl]# openssl req -new -key httpd.key  -out http.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) [CN]:
State or Province Name (full name) [Jiangsu]:
Locality Name (eg, city) [Kunshan]:
Organization Name (eg, company) [Fox]:jacktest  #此项要与服务方一致,否则签证不成功
Organizational Unit Name (eg, section) [Tech]:
Common Name (eg, your name or your server‘s hostname) []:hello.jacktest.com
Email Address []:[email protected]
          #hello.jacktest.com站点名称与证书站点名称一定要一致,否则有警告 
Please enter the following ‘extra‘ attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[[email protected] ssl]# ll
total 12
-rw-r--r-- 1 root root  704 Dec 28 09:45 http.csr
-rw------- 1 root root  887 Dec 28 09:40 httpd.key
[[email protected] ssl]# scp http.csr 192.168.1.5:/tmp

[[email protected] ssl]#


四、CA服务器收到后签署申请的证书

[[email protected] CA]# ll /tmp/http.csr
-rw-r--r-- 1 root root 708 Dec 28 10:05 /tmp/http.csr
[[email protected] CA]# openssl ca -in /tmp/http.csr -out /tmp/http.crt -days 3650

[email protected]‘s password:
http.crt      100%  3885    3.8KB/s   00:00    
[[email protected] tmp]#  rm -f http.*


[[email protected] ssl]# ll     #服务器192.168.1.3
total 16
-rw-r--r-- 1 root root  708 Dec 28 09:59 http.csr
-rw-r--r-- 1 root root 3885 Dec 28 10:25 http.crt
-rw------- 1 root root  887 Dec 28 09:57 httpd.key


五、CA服务器收到后签署申请的证书

[[email protected] conf.d]# vi ssl.conf

<VirtualHost 192.168.1.3:443>
# General setup for the virtual host, inherited from global configuration
#DocumentRoot "/var/www/html"
ServerName www.jacktest.com:443
DocumentRoot "/www/jacktest.com"

# Use separate log files for the SSL virtual host; note that LogLevel
# is not inherited from httpd.conf.
ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn

#   SSL Engine Switch:
#   Enable/Disable SSL for this virtual host.
SSLEngine on

#   SSL Protocol support:
# List the enable protocol levels with which clients will be able to
# connect.  Disable SSLv2 access by default:
SSLProtocol all -SSLv2  #除V2以外

#   Server Certificate:
# Point SSLCertificateFile at a PEM encoded certificate.  If
# the certificate is encrypted, then you will be prompted for a
# pass phrase.  Note that a kill -HUP will prompt again.  A new
# certificate can be generated using the genkey(1) command.
SSLCertificateFile /etc/httpd/ssl/httpd.crt

#   Server Private Key:
#   If the key is not combined with the certificate, use this
#   directive to point at the key file.  Keep in mind that if
#   you‘ve both a RSA and a DSA private key you can configure
#   both in parallel (to also allow the use of DSA ciphers, etc.)
SSLCertificateKeyFile /etc/httpd/ssl/httpd.key

[[email protected] conf.d]# ll /etc/httpd/ssl/http.crt
-rw-r--r-- 1 root root 3885 Dec 28 11:31 /etc/httpd/ssl/http.crt
[[email protected] conf.d]# httpd -t
Syntax OK
[[email protected] conf.d]# service httpd restart
Stopping httpd:                 [FAILED]
Starting httpd:                  [  OK  ]
[[email protected] conf.d]# netstat  -tnlp |grep :443
