Nginx服务器的SSL证书配置以及对SSL的反向代理配置

Nginx的SSL证书配置
1、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

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

2、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

3、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

4、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;

SSL反向代理
1.修改nginx.conf配置

server {
  listen   443 ssl;
  server_name  www.jb51.net;
 
  ssl_certificate  ssl/www.jb51.net.crt;
  ssl_certificate_key ssl/www.jb51.net.key;
  ssl_prefer_server_ciphers on;
  keepalive_timeout 60;
 ssl_session_cache shared:SSL:10m;
  ssl_session_timeout 10m;
 
  location / {
   proxy_pass http://www.jb51.net;
   proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    proxy_set_header  Accept-Encoding "";
   proxy_set_header  Host   $host;
   proxy_set_header  X-Real-IP  $remote_addr;
   proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header  X-Forwarded-Proto $scheme;
 add_header    Front-End-Https on;
   proxy_redirect  off;
  }
}

2.重启服务

# /usr/local/nginx/sbin/nginx -t
# /usr/local/nginx/sbin/nginx -s reload
