5.5.2. Configuring Booleans

Run the setsebool utility in the setsebool boolean_name on/off form to enable or disable Booleans.
The following example demonstrates configuring the httpd_can_network_connect_db Boolean:
  1. By default, the httpd_can_network_connect_db Boolean is off, preventing Apache HTTP Server scripts and modules from connecting to database servers: 
    ~]$ getsebool httpd_can_network_connect_db
httpd_can_network_connect_db --> off
    Copy to Clipboard Toggle word wrap
  2. To temporarily enable Apache HTTP Server scripts and modules to connect to database servers, run the setsebool httpd_can_network_connect_db on command as the Linux root user.
  3. Use the getsebool httpd_can_network_connect_db command to verify the Boolean is enabled: 
    ~]$ getsebool httpd_can_network_connect_db
httpd_can_network_connect_db --> on
    Copy to Clipboard Toggle word wrap
    This allows Apache HTTP Server scripts and modules to connect to database servers.
  4. This change is not persistent across reboots. To make changes persistent across reboots, run the setsebool -P boolean-name on command as the Linux root user:[7] 
    ~]# setsebool -P httpd_can_network_connect_db on
    Copy to Clipboard Toggle word wrap

[7] To temporarily revert to the default behavior, as the Linux root user, run the setsebool httpd_can_network_connect_db off command. For changes that persist across reboots, run the setsebool -P httpd_can_network_connect_db off command.
