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_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  ;   ssl_certificate  ssl/.crt;  ssl_certificate_key ssl/.key;  ssl_prefer_server_ciphers on;  keepalive_timeout 60; ssl_session_cache shared:SSL:10m;  ssl_session_timeout 10m;   location / {   proxy_pass //;   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
