在nginx中启用ssl安全认证连接，即访问可以以https开头的形式进行访问，如何来实现呢？
配置环境：
centos 6.5
nginx 1.6.2（安装通过yum安装，添加源，stable`稳定版本`，http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm）
二，nginx配置文件
nginx配置文件位置:
> /etc/nginx/conf.d/example_ssl.conf
修改/etc/nginx/conf.d/example_ssl.conf
注：
/etc/nginx/conf.d/example_ssl.conf是被/etc/nginx/nginx.conf包含到自身的一个文件。
修改为：
复制代码 代码示例:
#HTTP-SERVER
server {
listen 443;
server_name localhost;
ssi on;
ssi_silent_errors on;
ssi_types text/shtml;
ssl on;
ssl_certificate /etc/nginx/ca/server/server.crt;
ssl_certificate_key /etc/nginx/ca/server/server.key;
ssl_client_certificate /etc/nginx/ca/private/ca.crt;
ssl_session_timeout 5m;
ssl_verify_client on;
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
ssl_prefer_server_ciphers on;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
}
二，签发证书
创建配置文件/etc/nginx/ca/conf/openssl.conf
复制代码 代码示例:
[ ca ]
default_ca = foo # The default ca section
[ foo ]
dir = /etc/nginx/ca # top dir
database = /etc/nginx/ca/index.txt # index file.
new_certs_dir = /etc/nginx/ca/newcerts # new certs dir
certificate = /etc/nginx/ca/private/ca.crt # The CA cert
serial = /etc/nginx/ca/serial # serial no file
private_key = /etc/nginx/ca/private/ca.key # CA private key
RANDFILE = /etc/nginx/ca/private/.rand # random number file
default_days = 365 # how long to certify for
default_crl_days= 30 # how long before next CRL
default_md = md5 # message digest method to use
unique_subject = no # Set to 'no' to allow creation of
# several ctificates with same subject.
policy = policy_any # default policy
[ policy_any ]
countryName = match
stateOrProvinceName = match
organizationName = match
organizationalUnitName = match
localityName = match
commonName = match
emailAddress = match
在/etc/niginx/ca 下 创建文件new_ca.sh ,执行生成根证书
复制代码 代码示例:
#!/bin/sh
# Generate the key.
openssl genrsa -out private/ca.key
# Generate a certificate request.
openssl req -new -key private/ca.key -out private/ca.csr
# Self signing key is bad... this could work with a third party signed key... registeryfly has them on for $16 but I'm too cheap lazy to get one on a lark.
# I'm also not 100% sure if any old certificate will work or if you have to buy a special one that you can sign with. I could investigate further but since this
# service will never see the light of an unencrypted Internet see the cheap and lazy remark.
# So self sign our root key.
openssl x509 -req -days 365 -in private/ca.csr -signkey private/ca.key -out private/ca.crt
# Setup the first serial number for our keys... can be any 4 digit hex string... not sure if there are broader bounds but everything I've seen uses 4 digits.
echo FACE > serial
# Create the CA's key database.
touch index.txt
# Create a Certificate Revocation list for removing 'user certificates.'
openssl ca -gencrl -out /etc/nginx/ca/private/ca.crl -crldays 7 -config "/etc/nginx/ca/conf/openssl.conf"
在/etc/niginx/ca 下 创建文件new_server.sh，执行生成服务器证书：
复制代码 代码示例:
# Create us a key. Don't bother putting a password on it since you will need it to start
apache. If you have a better work around I'd love to hear it.
openssl genrsa -out server/server.key
# Take our key and create a Certificate Signing Request for it.
openssl req -new -key server/server.key -out server/server.csr
# Sign this bastard key with our bastard CA key.
openssl ca -in server/server.csr -cert private/ca.crt -keyfile private/ca.key -out server/server.crt -config "/etc/nginx/ca/conf/openssl.conf"
在/etc/niginx/ca 下 创建文件new_user.sh，执行生成客户端证书：
复制代码 代码示例:
#!/bin/sh
# The base of where our SSL stuff lives.
base="/etc/nginx/ca"
# Were we would like to store keys... in this case we take the username given to us and store everything there.
mkdir -p $base/users/
# Let's create us a key for this user... yeah not sure why people want to use DES3 but at least let's make us a nice big key.
openssl genrsa -des3 -out $base/users/client.key 1024
# Create a Certificate Signing Request for said key.
openssl req -new -key $base/users/client.key -out $base/users/client.csr
# Sign the key with our CA's key and cert and create the user's certificate out of it.
openssl ca -in $base/users/client.csr -cert $base/private/ca.crt -keyfile $base/private/ca.key -out $base/users/client.crt -config "/etc/nginx/ca/conf/openssl.conf"
# This is the tricky bit... convert the certificate into a form that most browsers will understand PKCS12 to be specific.
# The export password is the password u
sed for the browser to extract the bits it needs and insert the key into the user's keychain.
# Take the same precaution with the export password that would take with any other password based authentication scheme.
openssl pkcs12 -export -clcerts -in $base/users/client.crt -inkey $base/users/client.key -out $base/users/client.p12
然后，只需把/etc.nginx/ca/user/client.p12文件导入到浏览器中就可以了。
