MySQL Enterprise Firewall installation is a one-time operation that installs the components described in Section 126.96.36.199, “MySQL Enterprise Firewall Components”. Installation can be performed using a graphical interface or manually:
On Windows, MySQL Installer includes an option to enable MySQL Enterprise Firewall for you.
MySQL Workbench 6.3.4 or higher can install MySQL Enterprise Firewall, enable or disable an installed firewall, or uninstall the firewall.
Manual MySQL Enterprise Firewall installation involves running a script located in the
sharedirectory of your MySQL installation.
If installed, MySQL Enterprise Firewall involves some minimal overhead even when disabled. To avoid this overhead, do not install the firewall unless you plan to use it.
MySQL Enterprise Firewall does not work together with the query cache. If the query cache is enabled, disable it before installing the firewall (see Section 188.8.131.52, “Query Cache Configuration”).
For usage instructions, see Section 184.108.40.206, “Using MySQL Enterprise Firewall”. For reference information, see Section 220.127.116.11, “MySQL Enterprise Firewall Reference”.
If MySQL Enterprise Firewall is already installed from an older version of MySQL, uninstall it using the instructions given later in this section and then restart your server before installing the current version. In this case, it is also necessary to register your configuration again.
On Windows, you can use MySQL Installer to install MySQL Enterprise Firewall, as shown in Figure 6.2, “MySQL Enterprise Firewall Installation on Windows”. Check the Enable Enterprise Firewall checkbox. (Open Firewall port for network access has a different purpose. It refers to Windows Firewall and controls whether Windows blocks the TCP/IP port on which the MySQL server listens for client connections.)
To install MySQL Enterprise Firewall using MySQL Workbench 6.3.4 or higher, see MySQL Enterprise Firewall Interface.
To install MySQL Enterprise Firewall manually, look in the
share directory of your MySQL
installation and choose the script that is appropriate for
your platform. The available scripts differ in the suffix used
to refer to the plugin library file:
win_install_firewall.sql: Choose this script for Windows systems that use
.dllas the file name suffix.
linux_install_firewall.sql: Choose this script for Linux and similar systems that use
.soas the file name suffix.
The installation script creates stored procedures in the
default database, so choose a database to use. Then run the
script as follows, naming the chosen database on the command
line. The example here uses the
database and the Linux installation script. Make the
appropriate substitutions for your system.
shell> mysql -u root -p mysql < linux_install_firewall.sql Enter password: (enter root password here)
As of MySQL 5.7.21, for a new installation of MySQL Enterprise Firewall,
InnoDB is used instead of
MyISAM for the firewall tables. For
upgrades to an installation for which MySQL Enterprise Firewall is already
installed, it is recommended that you alter the firewall
tables to use
ALTER TABLE mysql.firewall_users ENGINE=InnoDB; ALTER TABLE mysql.firewall_whitelist ENGINE=InnoDB;
Installing MySQL Enterprise Firewall either using a graphical interface or manually should enable the firewall. To verify that, connect to the server and execute this statement:
mysql> SHOW GLOBAL VARIABLES LIKE 'mysql_firewall_mode'; +---------------------+-------+ | Variable_name | Value | +---------------------+-------+ | mysql_firewall_mode | ON | +---------------------+-------+
MySQL Enterprise Firewall can be uninstalled using MySQL Workbench or manually.
To uninstall MySQL Enterprise Firewall using MySQL Workbench 6.3.4 or higher, see MySQL Enterprise Firewall Interface.
To uninstall MySQL Enterprise Firewall manually, execute the following
statements. It is assumed that the stored procedures were
created in the
mysql database. Adjust the
DROP PROCEDURE statements
appropriately if the procedures were created in a different
DROP TABLE mysql.firewall_whitelist; DROP TABLE mysql.firewall_users; UNINSTALL PLUGIN mysql_firewall; UNINSTALL PLUGIN mysql_firewall_whitelist; UNINSTALL PLUGIN mysql_firewall_users; DROP FUNCTION set_firewall_mode; DROP FUNCTION normalize_statement; DROP FUNCTION read_firewall_whitelist; DROP FUNCTION read_firewall_users; DROP FUNCTION mysql_firewall_flush_status; DROP PROCEDURE mysql.sp_set_firewall_mode; DROP PROCEDURE mysql.sp_reload_firewall_rules;
