How to configure ezeelogin jump server to use SSL for MySQL database connections on centos ?

Mysql-SSL setup on Centos 7,mysql server 5.5 version

1. Check the Current SSL/TLS Status

Log into a MySQL session

root@gateway:~# mysql -u root -p -h 127.0.0.1

Show the state of the SSL/TLS variables by typing:

mysql> SHOW VARIABLES LIKE '%ssl%';
Output
+---------------+----------+
| Variable_name | Value    |
+---------------+----------+
| have_openssl  | DISABLED |
| have_ssl      | DISABLED |
| ssl_ca        |          |
| ssl_capath    |          |
| ssl_cert      |          |
| ssl_cipher    |          |
| ssl_crl       |          |
| ssl_crlpath   |          |
| ssl_key       |          |
+---------------+----------+
9 rows in set (0.01 sec)
 

The have_openssl and have_ssl variables are both marked as DISABLED. This means that SSL functionality has been compiled into the server, but that it is not yet enabled.

2. Generate SSL/TLS Certificates and Keys

Create clean environment

root@gateway:~# mkdir /etc/certs && cd /etc/certs

Create CA certificate

root@gateway:~#openssl genrsa 2048 > ca-key.pem

root@gateway:~#openssl req -new -x509 -nodes -days 3600 \
-key ca-key.pem -out ca.pem

Create server certificate, remove passphrase, and sign it

root@gateway:~#openssl req -newkey rsa:2048 -days 3600 \
-nodes -keyout server-key.pem -out server-req.pem

root@gateway:~#openssl rsa -in server-key.pem -out server-key.pem

root@gateway:~#openssl x509 -req -in server-req.pem -days 3600 \
-CA ca.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem

Create client certificate, remove passphrase, and sign it

root@gateway:~#openssl req -newkey rsa:2048 -days 3600 \
-nodes -keyout client-key.pem -out client-req.pem

root@gateway:~#openssl rsa -in client-key.pem -out client-key.pem

root@gateway:~#openssl x509 -req -in client-req.pem -days 3600 \
-CA ca.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem

After generating the certificates, verify them:

root@gateway:~# openssl verify -CAfile ca.pem server-cert.pem client-cert.pem

output

server-cert.pem: OK
client-cert.pem: Ok

Enable SSL for MySQL

We have to edit the MySQL configuration file '/etc/my.cnf'

In the '[mysqld]' section, paste the configuration below.

root@gateway:~# vi /etc/my.cnf

ssl-ca=/etc/certs/ca.pem

ssl-cert=/etc/certs/server-cert.pem

ssl-key=/etc/certs/server-key.pem

Restart the MySQL service

root@gateway:~# systemctl restart mysql

After restarting, open up a new MySQL session using the same command as before.

root@gateway:~# mysql -u root -p -h 127.0.0.1

Check state of the SSL/TLS variables by typing:

mysql> SHOW VARIABLES LIKE '%ssl%';
Output
+---------------+----------------+
| Variable_name | Value          |
+---------------+----------------+
| have_openssl  | YES            |
| have_ssl      | YES            |
| ssl_ca        | Ca.pem         |
| ssl_capath    |                |
| ssl_cert      | server-cert.pem|
| ssl_cipher    |                |
| ssl_crl       |                |
| ssl_crlpath   |                |
| ssl_key       | server-key.pem |
+---------------+----------------+
9 rows in set (0.01 sec)
 

The have_openssl and have_ssl variables read "YES" instead of "DISABLED" this time.

Check the connection details by the following command :

[root@localhost ~]# mysql -u ezlogin_database_username -p -h hostname or ip --ssl-ca=/etc/certs/ca.pem --ssl-cert=/etc/certs/client-cert.pem --ssl-key=/etc/certs/client-key.pem

example :

[root@localhost ~]# mysql -u ezlogin_xxxx -p -h 10.11.1.11 --ssl-ca=/etc/certs/ca.pem --ssl-cert=/etc/certs/client-cert.pem --ssl-key=/etc/certs/client-key.pem

mysql> \s
--------------- 
. . .
SSL: Cipher in use is DHE-RSA-AES256-SHA
. . .
Connection: 127.0.0.1 via TCP/IP
. . .
---------------- 

SSL cipher is displayed, indicating that SSL is being used to secure our connection.

3. Configure ezeelogin jump server to use SSL for Mysql 5.5

Add mysql_ssl_key,mysql_ssl_cert,mysql_ssl_ca to /usr/local/etc/ezlogin/ez.conf

Edit the /usr/local/etc/ezlogin/ez.conf file add the following

root@gateway:~# vi /usr/local/etc/ezlogin/ez.conf
#Add the following system_folder /var/www/ezlogin/
force_https no
uri_path /ezlogin/
db_host 10.10.1.11
db_port 3306
db_name ezlogin_qzms
db_user ezlogin_edcjwz
db_pass dsH)$s5xAE[QgFms
db_prefix aqvo_
cookie_encryption_key ASvs8^pnu^^X9
cookie_name lcrrfs
cookie_path /ezlogin/
www_folder /var/www/html/ezlogin/
admin_user admin
mysql_encrypt yes
mysql_ssl_key /etc/certs/client-key.pem
mysql_ssl_cert /etc/certs/client-cert.pem
mysql_ssl_ca /etc/certs/ca.pem
mysql_ssl_capath /etc/certs/
mysql_ssl_cipher DHE-RSA-AES256-SHA
mysql_ssl_verify no

Make sure that you have changed db_port to 3306 & db_host to IP Address of your host

4. Change the bind-address & allow the ezeelogin jump server user to access the database.

Edit the /etc/mysql/mysql.conf.d/mysqld.cnf & change bind-address

root@gateway:~# vi /etc/mysql/mysql.conf.d/mysqld.cnf
 
Change bind-address to host ip(server ip)
bind-address x.x.x.x (Host ip)

Restart the MySQL service

root@gateway:~# systemctl restart mariadb

you can find out ezeelogin jump server dbname and ezeelogin mysql username from the ez.conf file

root@gateway:~# cat /usr/local/etc/ezlogin/ez.conf

system_folder /var/www/ezlogin/
force_https no
uri_path /ezlogin/
db_host 10.10.1.11
db_port 3306
db_name ezlogin_qzms
db_user ezlogin_edcjwz
db_pass dsH)$s5xAE[QgFms
db_prefix aqvo_
cookie_encryption_key ASvs8^pnu^^X9
cookie_name lcrrfs
cookie_path /ezlogin/
www_folder /var/www/html/ezlogin/
admin_user admin
mysql_encrypt yes
mysql_ssl_key /etc/certs/client-key.pem
mysql_ssl_cert /etc/certs/client-cert.pem
mysql_ssl_ca /etc/certs/ca.pem
mysql_ssl_capath /etc/certs/
mysql_ssl_cipher DHE-RSA-AES256-SHA
mysql_ssl_verify no

root@gateway:~# mysql -u root -p 
[Enter password]
mysql> grant all on ezlogin_databasename.* to 'mysql_username'@'%' identified by 'password';
example : mysql > grant all on ezlogin_xxx.* to 'ezlogin_xxxx'@'%' identified by 'dsH)$s5xAE[QgFmfsfgg';
mysql > flush privileges;
mysql > exit 

Check if you can login to mysql using ezeelogin databases

root@gateway:~# mysql -u ezeelogin_databasename_username -h 10.11.1.11 -p
Enter Password:
mysql >
mysql > exit
