nginx配置ssl双向验证－龍之家族

引用網址：http://www.zhengdazhi.com/archives/865

通过ssl加密nginx除了可以搭建https的站点之外还可以使用对某些非完全公开的web站点做基于证书验证的通信，例如将公司的OA发布在公网上，用于个出差或在家里办公的用户使用，可以针对这些用户颁发证书，只有获得证书的用户才能对网站进行访问。

1、安装nginx略

2、使用openssl实现证书中心

由于是使用openssl架设私有证书中心，因此要保证以下字段在证书中心的证书、服务端证书、客户端证书中都相同
Country Name
State or Province Name
Locality Name
Organization Name
Organizational Unit Name

编辑证书中心配置文件

vim /etc/pki/tls/openssl.cnf
[ CA_default ]
dir             = /etc/pki/
certs           = $dir/certs            # Where the issued certs are kept
crl_dir         = $dir/crl              # Where the issued crl are kept
database        = $dir/index.txt        # database index file.
#unique_subject = no                    # Set to 'no' to allow creation of<br />                                        # several ctificates with same subject.
new_certs_dir   = $dir/newcerts         # default place for new certs.
certificate     = $dir/cacert.pem       # The CA certificate
serial          = $dir/serial           # The current serial number
crlnumber       = $dir/crlnumber        # the current crl number       # must be commented out to leave a V1 CRL
crl             = $dir/crl.pem          # The current CRL
private_key     = $dir/private/cakey.pem# The private key
RANDFILE        = $dir/private/.rand    # private random number file
[ 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     = FJ
localityName                    = Locality Name (eg, city)
localityName_default            = FZ
0.organizationName              = Organization Name (eg, company)
0.organizationName_default      = zdz
organizationalUnitName          = Organizational Unit Name (eg, section)
organizationalUnitName_default  = zdz

创建证书私钥

cd /etc/pki/CA/
(umask 077;openssl genrsa -out cakey.pem 2048)

生成自签证书

cd /etc/pki/CA/
openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days=3655

3、创建服务器证书

mkdir /usr/local/nginx/ssl
cd /usr/local/nginx/ssl
(umask 077;openssl genrsa -out nginx.key 1024)
openssl req -new -key nginx.key -out nginx.csr
openssl ca -in nginx.csr -out nginx.crt -days=3650

4、创建客户端浏览器证书

(umask 077;openssl genrsa -out client.key 1024)
openssl req -new -key client.key -out client.csr
openssl ca -in client.csr -out client.crt -days=3650

5、将文本格式的证书转换成可以导入浏览器的证书

openssl pkcs12 -export -clcerts -in client.crt -inkey client.key -out client.p12

6、配置nginx服务器验证

vim /usr/local/nginx/conf/nginx.conf
 ssl on;
 ssl_certificate         /usr/local/nginx/ssl/nginx.crt;
 ssl_certificate_key     /usr/local/nginx/ssl/nginx.key;
 ssl_client_certificate  /usr/local/nginx/ssl/cacert.pem;
 ssl_session_timeout     5m;
 #ssl_verify_client       on;                         服务器验证客户端，暂时不开启，让没有证书的客户端可以访问，先完成单向验证
 ssl_protocols           SSLv2 SSLv3 TLSv1;
