NAME
mysql_ssl_rsa_setup - create SSL/RSA files
SYNOPSIS
mysql_ssl_rsa_setup [options]
DESCRIPTION
This program creates the SSL certificate and key files and RSA key-pair
files required to support secure connections using SSL and secure
password exchange using RSA over unencrypted connections, if those
files are missing. mysql_ssl_rsa_setup can also be used to create new
SSL files if the existing ones have expired.
Note
mysql_ssl_rsa_setup uses the openssl command, so its use is
contingent on having OpenSSL installed on your machine.
Another way to generate SSL and RSA files, for MySQL distributions
compiled using OpenSSL, is to have the server generated them
automatically. See Section 7.4.6.1, "Creating SSL and RSA
Certificates and Keys using MySQL".
Important
mysql_ssl_rsa_setup helps lower the barrier to using SSL by making
it easier to generate the required files. However, certificates
generated by mysql_ssl_rsa_setup are self-signed, which is not very
secure. After you gain experience using the files created by
mysql_ssl_rsa_setup, consider obtaining a CA certificate from a
registered certificate authority.
Invoke mysql_ssl_rsa_setup like this:
shell> mysql_ssl_rsa_setup [options]
Typical options are --datadir to specify where to create the files, and
--verbose to see the openssl commands that mysql_ssl_rsa_setup
executes.
mysql_ssl_rsa_setup attempts to create SSL and RSA files using a
default set of file names. It works as follows:
1. mysql_ssl_rsa_setup checks for the openssl binary at the locations
specified by the PATH environment variable. If openssl is not
found, mysql_ssl_rsa_setup does nothing. If openssl is present,
mysql_ssl_rsa_setup looks for default SSL and RSA files in the
MySQL data directory specified by the --datadir option, or the
compiled-in data directory if that option is not given.
2. mysql_ssl_rsa_setup checks the data directory for SSL files with
the following names:
ca.pem
server-cert.pem
server-key.pem
3. If any of those files are present, mysql_ssl_rsa_setup creates no
SSL files. Otherwise, it invokes openssl to create them, plus some
additional files:
ca.pem Self-signed CA certificate
ca-key.pem CA private key
server-cert.pem Server certificate
server-key.pem Server private key
client-cert.pem Client certificate
client-key.pem Client private key
These files enable secure client connections using SSL; see
Section 7.4.4, "Configuring MySQL to Use Secure Connections".
4. mysql_ssl_rsa_setup checks the data directory for RSA files with
the following names:
private_key.pem Private member of private/public key pair
public_key.pem Public member of private/public key pair
5. If any of these files are present, mysql_ssl_rsa_setup creates no
RSA files. Otherwise, it invokes openssl to create them. These
files enable secure password exchange using RSA over unencrypted
connections for accounts authenticated by the sha256_password
plugin; see Section 7.5.1.4, "The SHA-256 Authentication Plugin".
For information about the characteristics of files created by
mysql_ssl_rsa_setup, see Section 7.4.6.1, "Creating SSL and RSA
Certificates and Keys using MySQL".
At startup, the MySQL server automatically uses the SSL files created
by mysql_ssl_rsa_setup to enable SSL if no explicit SSL options are
given other than --ssl. If you prefer to designate the files
explicitly, use the --ssl-ca, --ssl-cert, and --ssl-key options at
startup to name the ca.pem, server-cert.pem, and server-key.pem files,
respectively.
The server also automatically uses the RSA files created by
mysql_ssl_rsa_setup to enable RSA if no explicit RSA options are given.
If the server is SSL-enabled, clients need only use --ssl on the
command line to use SSL for the connection. To specify certificate and
key files explicitly, use the --ssl-ca, --ssl-cert, and --ssl-key
options to name the ca.pem, client-cert.pem, and client-key.pem files,
respectively. However, some additional client setup may be required
first because mysql_ssl_rsa_setup by default creates those files in the
data directory. The permissions for the data directory normally enable
access only to the system account that runs the MySQL server, so client
programs cannot use files located there. To make the files available,
copy them to a directory that is readable (but not writable) by
clients:
o For local clients, the MySQL installation directory can be used.
For example, if the data directory is a subdirectory of the
installation directory and your current location is the data
directory, you can copy the files like this:
shell> cp ca.pem client-cert.pem client-key.pem ..
o For remote clients, distribute the files using a secure channel to
ensure they are not tampered with during transit.
If the SSL files used for a MySQL installation have expired, you can
use mysql_ssl_rsa_setup to create new ones:
1. Stop the server.
2. Rename or remove the existing SSL files. You may wish to make a
backup of them first. (The RSA files do not expire, so you need not
remove them. mysql_ssl_rsa_setup will see that they exist and not
overwrite them.)
3. Run mysql_ssl_rsa_setup with the --datadir option to specify where
to create the new files.
4. Restart the server.
mysql_ssl_rsa_setup supports the following command-line options, which
can be specified on the command line or in the [mysql_ssl_rsa_setup],
[mysql_install_db], and [mysqld] groups of an option file. For
information about option files used by MySQL programs, see
Section 5.2.6, "Using Option Files".
o --help, ?
Display a help message and exit.
o --datadir=dir_name
The path to the directory that mysql_ssl_rsa_setup should check for
default SSL and RSA files and in which it should create files if
they are missing. The default is the compiled-in data directory.
o --suffix=str
The suffix for the Common Name attribute in X509 certificates. The
suffix value is limited to 17 characters. The default is based on
the MySQL version number.
o --uid=name, -v
The name of the user who should be the owner of any created files.
The value is a user name, not a numeric user ID. In the absence of
this option, files created by mysql_ssl_rsa_setup are owned by the
user who executes it. This option is valid only if you execute the
program as root on a system that supports the chown() system call.
This option was added in MySQL 5.7.8.
o --verbose, -v
Verbose mode. Produce more output about what the program does. For
example, the program shows the openssl commands it runs, and
produces output to indicate whether it skips SSL or RSA file
creation because some default file already exists.
o --version, -V
Display version information and exit.
