Linux学习-Nginx学习实现https

Posted 2022-05-03 丢爸

本实例基于在服务器自已颁发证书，自己生成私钥，自己实现证书的签发

1. 建立CA

[root@nginx01 ~]# cd /etc/pki/CA
[root@nginx01 CA]# ls
certs  crl  newcerts  private
[root@nginx01 CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
....................................+++
.......................+++
e is 65537 (0x10001)
[root@nginx01 CA]# ls -l private/
total 4
-rw------- 1 root root 1675 Apr 29 19:48 cakey.pem

2. 创建自签证书

[root@nginx01 CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3655
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) []:HN
Locality Name (eg, city) [Default City]:ZZ
Organization Name (eg, company) [Default Company Ltd]:tye
Organizational Unit Name (eg, section) []:ops
Common Name (eg, your name or your server's hostname) []:ca.tye.com
Email Address []:[e-mail]
[root@nginx01 CA]# ls
cacert.pem  certs  crl  newcerts  private
[root@nginx01 CA]# touch serial index.txt
[root@nginx01 CA]# echo 01 > serial 

3. 创建密钥文件

[root@nginx01 CA]# cd /etc/nginx/
[root@nginx01 nginx]# mkdir ssl
[root@nginx01 nginx]# cd ssl
[root@nginx01 ssl]# (umask 077;openssl genrsa -out nginx.key 1024)
Generating RSA private key, 1024 bit long modulus
.................................++++++
.......................................++++++
e is 65537 (0x10001)
[root@nginx01 ssl]# ll
total 4
-rw------- 1 root root 887 Apr 29 19:52 nginx.key

4. 生成证书签发请求

[root@nginx01 ssl]# openssl req -new -key nginx.key -out nginx.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) []:HN
Locality Name (eg, city) [Default City]:ZZ
Organization Name (eg, company) [Default Company Ltd]:tye
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:www.tye.com
Email Address []:[e-mail]

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

5. 签发证书

[root@nginx01 ssl]# openssl ca -in nginx.csr -out nginx.crt -days 3655
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok
