11.1.2 Testing Apache apr-util-ldap.s390x 0:1.3.9-3.el6 httpd-tools.s390x 0:2.2.15-5.el6 Complete! ► Verify that the RPMs were installed # rpm -qa | grep httpd httpd-tools-2.2.15-5.el6.s390x httpd-manual-2.2.15-5.el6.noarch httpd-2.2.15-5.el6.s390x ► Before starting the Apache Web server, use the chkconfig command to set the service to start at boot time: # chkconfig --list httpd httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off # chkconfig httpd on # chkconfig --list httpd httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off Start the Apache Web server to verify it is installed successfully. # service httpd start Starting httpd: [ OK ] To verify that Apache is installed correctly, after it’s been started, bring up a Web browser and point it to the server. For example, the virtual server running on LINUX01 can be reached with the following URL: http://9.60.18.224/ You should see the following test page to verify the Web server is working: 170 The Virtualization Cookbook for RHEL 6
Figure 11-1 Apache test page If you get an error in starting Apache, look in the log file /var/log/httpd/error-log for clues. If Apache started successfully but you can’t reach the test page from a browser, try accessing it using the IP address rather than the DNS name. 11.1.3 Turning on a firewall RHEL 6 comes with an IP tables firewall. In section 8.2.3, “Turning off unneeded services” on page 140, it was recommended that you turn off the iptables service. If you did this on the golden image, the firewall is turned off on this clone. This section describes how to quickly enable an IP tables firewall and configure it to allow Web traffic through. Perform the following steps: ► Verify that the firewall is off with the chkconfig --list command. The service name is iptables: # chkconfig --list iptables iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off ► Turn on the firewall at boot time with the chkconfig command, and for this session with the service command: # chkconfig iptables on # service iptables start Applying iptables firewall rules: [ OK ] Loading additional iptables modules: ip_conntrack_netbios_ns [ OK ] ► Go back to your browser and click refresh. You should get an error that the server is not responding (or Unable to connect). This is because packets for ports for http: and https: (80 and 443) are dropped by default. Chapter 11.
