Typically, you can set the following settings

Mysql> flush Privileges;
Mysql> exit

# Getsebool-a | grep httpd

# setsebool Httpd_can_network_connect 1

3. Re-verify Httpd_can_network_connect
# Getsebool-a | grep httpd

4. Restart the HTTP
#/etc/init.d/httpd restart

5. Enter the client to restart login verification
