nginx配置ssl双向验证 nginx https ssl证书配置

1、安装nginx

参考《nginx安装》：http://www.ttlsa.com/nginx/nginx-install-on-linux/

如果你想在单IP/服务器上配置多个https，请看《nginx 同一个IP上配置多个HTTPS主机》

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

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/CA
 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
 # 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

vim /etc/pki/tls/openssl.cnf

[ CA_default ]

dir = /etc/pki/CA

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

# 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/private
 (umask 077;openssl genrsa -out cakey.pem 2048)

1 2	cd /etc/pki/CA/private (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

1 2	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

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
 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

(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

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

5、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;
