-## Configuration - -Edit the `python.d/mysql.conf` configuration file using `edit-config` from the Netdata [config -directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`. - -```bash -cd /etc/netdata # Replace this path with your Netdata config directory, if different -sudo ./edit-config python.d/mysql.conf -``` - -You can provide, per server, the following: - -1. username which have access to database (defaults to 'root') -2. password (defaults to none) -3. mysql my.cnf configuration file -4. mysql socket (optional) -5. mysql host (ip or hostname) -6. mysql port (defaults to 3306) -7. ssl connection parameters - - - key: the path name of the client private key file. - - cert: the path name of the client public key certificate file. - - ca: the path name of the Certificate Authority (CA) certificate file. This option, if used, must specify the - same certificate used by the server. - - capath: the path name of the directory that contains trusted SSL CA certificate files. - - cipher: the list of permitted ciphers for SSL encryption. - -Here is an example for 3 servers: - -```yaml -update_every : 10 -priority : 90100 - -local: - 'my.cnf' : '/etc/mysql/my.cnf' - priority : 90000 - -local_2: - user : 'root' - pass : 'blablablabla' - socket : '/var/run/mysqld/mysqld.sock' - update_every : 1 - -remote: - user : 'admin' - pass : 'bla' - host : 'example.org' - port : 9000 -``` - -If no configuration is given, the module will attempt to connect to MySQL server via a unix socket at -`/var/run/mysqld/mysqld.sock` without password and with username `root` or `netdata` (you granted permissions for `netdata` user in the Requirements section of this document). - -`userstats` graph works only if you enable the plugin in MariaDB server and set proper MySQL privileges (SUPER or -PROCESS).
