Nginx服务器SSL证书
生成pass key
下面的命令用于生成一个2048bit的pass key, -passout pass:111111 用于避免交互式输入密码
| 1 2 3 4 5 |
[tomcat@a02 tmp]$ openssl genrsa -aes256 -passout pass:111111 -out server.pass.key 2048
Generating RSA private key, 2048 bit long modulus

生成key
下面的命令用于生成私钥, -passin pass:111111是和pass key的密码对应的, 用于避免交互式输入密码
| 1 2 |
[tomcat@a02 tmp]$ openssl rsa -passin pass:111111 -in server.pass.key -out server.key

生成证书签发请求文件(CSR)
下面的命令用于生成csr文件, 这里需要填写机构相关信息. 其中CN务必填写为对应的服务器域名. 最后那个challenge password, 是这个csr的password
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
[tomcat@a02 tmp]$ openssl req -new -sha256 -key server.key -out server.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:Beijing
Locality Name (eg, city) [Default City]:Chaoyang
Organization Name (eg, company) [Default Company Ltd]:HenSomeone
Organizational Unit Name (eg, section) []:iSomeone
Common Name (eg, your name or your server's hostname) []:internal.someone.com
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:222222
An optional company name []:

发送CSR文件给CA服务商签发证书
如果是购买的CA服务商的SSL证书服务, 这一步把CSR发给服务商就可以了. 收到证书后将内容写入到 server.pem 文件
在Nginx上这样配置
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
server {
listen 443;
server_name www.example.com;
ssl on;
ssl_certificate /path/to/ssl/server.pem;
ssl_certificate_key /path/to/ssl/server.key;
ssl_protocols TLSv1.2 TLSv1.1 TLSv1;
ssl_session_cache shared:ssl_www_example_com:5m;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:ECDHE-ECDSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:DES-CBC3-SHA;

制作自签名证书
如果是打算制作自签名证书, 则进行如下的操作生成pem证书
| 1 2 3 4 |
[tomcat@a02 tmp]$ openssl x509 -req -sha256 -days 3655 -in server.csr -signkey server.key -out server.pem
Signature ok
subject=/C=CN/ST=Beijing/L=Chaoyang/O=HenSomeone/OU=iSomeone/CN=internal.someone.com

Nginx客户端验证证书
Nginx客户端验证证书和服务端SSL证书其实是没关系的, 你可以一边使用CA签发的证书, 一边使用自己制作的客户端验证证书.
生成服务器端私钥
| 1 2 3 4 5 6 7 8 |
[tomcat@a02 tmp]$ openssl genrsa -aes256 -passout pass:201906 -out ca.pass.key 2048
Generating RSA private key, 2048 bit long modulus
...............................................................................................................+++

[tomcat@a02 tmp]$ openssl rsa -passin pass:201906 -in ca.pass.key -out ca.key

生成服务器端证书
下面的命令会生成服务器证书ca.pem, 用于配制到nginx.
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
[tomcat@a02 tmp]$ openssl req -new -x509 -days 3655 -key ca.key -out ca.pem

签发客户端证书
下面的命令, 用服务端的私钥和服务端的证书, 对客户端的CSR进行签发, 生成服务端证书. 这里有一个 -set_serial 01 的参数, 如果签发多个客户端证书, 这个数字不能重复
| 1 2 3 4 |
[tomcat@a02 tmp]$ openssl x509 -req -days 3655 -in client_01.csr -CA ca.pem -CAkey ca.key -set_serial 01 -out client_01.pem
Signature ok
subject=/C=CN/ST=Beijing/L=Chaoyang/O=HenSomeone/OU=Staff/CN=Staff
Getting CA Private Key
|
客户端证书格式转换
前面生成的证书, 不能直接用于常见的应用, 需要转换成应用需要的格式
Full PEM:
| 1 |
[tomcat@a02 tmp]$ cat client_01.key client_01.pem ca.pem > client_01.full.pem
|
PFX - 这里输入的export password, 就是应用导入PFX证书时需要输入的密码.
| 1 2 3 |
[tomcat@a02 tmp]$ openssl pkcs12 -export -out client_01.full.pfx -inkey client_01.key -in client_01.pem -certfile ca.pem
Enter Export Password:
Verifying - Enter Export Password:

配置Nginx的客户端验证证书

ssl_client_certificate /path/to/ca.pem;
ssl_verify_client optional; # or `on` if you require client key
