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 NameCountry 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_timeout5m; #ssl_verify_clienton; 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_namewww.jb51.net; ssl_certificatessl/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_headerAccept-Encoding ""; proxy_set_headerHost $host; proxy_set_headerX-Real-IP$remote_addr; proxy_set_headerX-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_headerX-Forwarded-Proto $scheme; add_headerFront-End-Https on; proxy_redirectoff;}}

2.重启服务

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