1. The previously exposed interface address is http://192.168.2.246
Because the domain name is mapped, it needs to be upgraded to https. Since it is accessed by IP address, generate a self-signed certificate and set nginx
2. Create a new_cert directory under the home directory to store certificates and related files
[root@localhost home]# mkdir new_cert
3. Use openssl to generate the public key and private key of the server and client respectively
1. Generate server private key
(base) [root@localhost ~]# mkdir new_cert
(base) [root@localhost ~]# cd new_cert/
(base) [root@localhost new_cert]# openssl genrsa -out server.key 1024
Generating RSA private key, 1024 bit long modulus (2 primes)
.......................+++++
............+++++
e is 65537 (0x010001)
2. Generate server public key
(base) [root@localhost new_cert]# openssl rsa -in server.key -pubout -out server.pem
writing RSA key
(base) [root@localhost new_cert]# openssl genrsa -out client.key 1024
Generating RSA private key, 1024 bit long modulus (2 primes)
.........................+++++
..........+++++
e is 65537 (0x010001)
3. Generate client private key
(base) [root@localhost new_cert]# openssl rsa -in client.key -pubout -out client.pem
writing RSA key
4. Generate client public key
(base) [root@localhost new_cert]# ll
total 16
-rw------- 1 root root 887 Apr 6 14:44 client.key
-rw-r--r-- 1 root root 272 Apr 6 14:44 client.pem
-rw------- 1 root root 887 Apr 6 14:43 server.key
-rw-r--r-- 1 root root 272 Apr 6 14:44 server.pem
(base) [root@localhost new_cert]#
4. Generate CA certificate
1. Generate CA private key
(base) [root@localhost new_cert]# openssl genrsa -out ca.key 1024
Generating RSA private key, 1024 bit long modulus (2 primes)
..........+++++
.........................+++++
e is 65537 (0x010001)
(base) [root@localhost new_cert]#
2. Generate CA certificate signing request file CSR
(base) [root@localhost new_cert]# openssl req -new -key ca.key -out ca.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) [AU]:cn
State or Province Name (full name) [Some-State]:beijing
Locality Name (eg, city) []:chaoyang
Organization Name (eg, company) [Internet Widgits Pty Ltd]:hlhk_ca
Organizational Unit Name (eg, section) []:hlhk_sms_ca
Common Name (e.g. server FQDN or YOUR name) []:192.168.2.246
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:123456
An optional company name []:192.168.2.246
(base) [root@localhost new_cert]#
3. Use the private key KEY file and CSR file signature to generate a CRT certificate
(base) [root@localhost new_cert]# openssl x509 -req -in ca.csr -signkey ca.key -out ca.crt
Signature ok
subject=C = cn, ST = beijing, L = chaoyang, O = hlhk_ca, OU = hlhk_sms_ca, CN = 192.168.2.246
Getting Private key
(base) [root@localhost new_cert]#
5. Generate server-side and client-side CRT certificates
1. Generate server signature request CSR file
(base) [root@localhost new_cert]# openssl req -new -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) [AU]:cn
State or Province Name (full name) [Some-State]:beijing
Locality Name (eg, city) []:chaoyang
Organization Name (eg, company) [Internet Widgits Pty Ltd]:hlhk_serve
Organizational Unit Name (eg, section) []:hlhk_sms_serve
Common Name (e.g. server FQDN or YOUR name) []:192.168.2.246
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:192.168.2.246
(base) [root@localhost new_cert]#
2. Generate client signature request CSR file
(base) [root@localhost new_cert]# openssl req -new -key client.key -out client.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) [AU]:cn
State or Province Name (full name) [Some-State]:beijing
Locality Name (eg, city) []:chaoyang
Organization Name (eg, company) [Internet Widgits Pty Ltd]:hlhk_client
Organizational Unit Name (eg, section) []:hlhk_sms_client
Common Name (e.g. server FQDN or YOUR name) []:192.168.2.246
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:123456
An optional company name []:192.168.2.246
(base) [root@localhost new_cert]#
Here, the Organization Name (eg, company) and Organizational Unit Name of the server and client must be different from those of the CA.
3. Apply for a signed CRT certificate (server and client) from your own CA organization just generated
(base) [root@localhost new_cert]# openssl x509 -req -CA ca.crt -CAkey ca.key -CAcreateserial -in server.csr -out server.crt
Signature ok
subject=C = cn, ST = beijing, L = chaoyang, O = hlhk_serve, OU = hlhk_sms_serve, CN = 192.168.2.246
Getting CA Private Key
(base) [root@localhost new_cert]# openssl x509 -req -CA ca.crt -CAkey ca.key -CAcreateserial -in client.csr -out client.crt
Signature ok
subject=C = cn, ST = beijing, L = chaoyang, O = hlhk_client, OU = hlhk_sms_client, CN = 192.168.2.246
Getting CA Private Key
(base) [root@localhost new_cert]#

-rw-r--r-- 1 root root 272 Apr 6 14:44 server.pem
(base) [root@localhost new_cert]#
6. Finally generate the required key and crt files
(base) [root@localhost new_cert]# openssl rsa -in server.key -out server_nginx.key
writing RSA key
(base) [root@localhost new_cert]# openssl x509 -req -days 3650 -in server.csr -signkey server_nginx.key -out server_nginx.crt
