nginx配置ssl双向验证的方法

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/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)
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
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;
