5.5.7.3 Configurer les certificats SSL pour MySQL

Voici un exemple de configuration de certificats SSL pour MySQL :

DIR=`pwd`/openssl
PRIV=$DIR/private

mkdir $DIR $PRIV $DIR/newcerts
cp /usr/share/ssl/openssl.cnf $DIR
replace ./demoCA $DIR -- $DIR/openssl.cnf

# Créez les dossiers nécessaires : $database, $serial et $new_certs_dir
# optionnel

touch $DIR/index.txt
echo "01" > $DIR/serial

#
# Génération du cerificat d'autorité (CA)
#

openssl req -new -x509 -keyout $PRIV/cakey.pem -out $DIR/cacert.pem \
    -config $DIR/openssl.cnf

# Exemple de résultat :

# 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

cnf=""
cnf="$cnf [client]"
cnf="$cnf ssl-ca=$DIR/cacert.pem"
cnf="$cnf ssl-cert=$DIR/client-cert.pem"
cnf="$cnf ssl-key=$DIR/client-key.pem"
cnf="$cnf [mysqld]"
cnf="$cnf ssl-ca=$DIR/cacert.pem"
cnf="$cnf ssl-cert=$DIR/server-cert.pem"
cnf="$cnf ssl-key=$DIR/server-key.pem"
echo $cnf | replace " " '
' > $DIR/my.cnf

#
# To test MySQL

mysqld --defaults-file=$DIR/my.cnf &

mysql --defaults-file=$DIR/my.cnf
Pour tester les connexions SSL, lancez le serveur comme ceci, où $DIR est le dossier où le fichier de configuration my.cnf est situé :

shell> mysqld --defaults-file=$DIR/my.cnf &
Puis, lancez le programme client en utilisant le même fichier d'options :

shell> mysql --defaults-file=$DIR/my.cnf
Si vous avez une distribution source MySQL, vous pouvez aussi tester votre configuration en modifiant le fichier my.cnf précédent, pour utiliser les certificats et fichiers de clé SSL de la distribution.
