14 <h2>Basic info for the guest VM</h2>
16 <li>hostname: cakelampvm.com</li>
17 <li>local IP address: 10.28.42.20</li>
18 <li>services: DNS (bind9), apache2, fluxbox X windowing system, gnome
20 <li>main user: developer (password distributed separately)</li>
21 <li>mysql root password: (password distributed separately)</li>
23 <h2>How to set up virtualbox for your host PC</h2>
25 <li>Download and install virtualbox:
26 https://www.virtualbox.org/wiki/Downloads</li>
27 <li>Install the extension pack for virtualbox: This provides USB drivers
28 and other features. This is installed on virtualbox itself, not on
31 <li>Download the extension pack at
32 https://www.virtualbox.org/wiki/Downloads</li>
33 <li>Stop any running virtualbox vms.</li>
34 <li>Close virtualbox control panel.</li>
35 <li>Double-click on the downloaded extensions package (in a file
36 explorer) and virtualbox should install it.</li>
38 <li>Run the virtualbox control panel.</li>
39 <li>Download the cakelampvm guest vm package and unzip it. Store the
40 unzipped version in some appropriate place where you want the virtual
41 machine to reside on your host's hard drive.</li>
42 <li>Add the guest VM to your list of VMs. From the virtualbox menus,
43 choose the "Machine" menu and select "Add". Point the selector
44 dialog at the cakelampvm folder you created above and open the
45 cakelampvm.vbox file.</li>
46 <li>Now the cakelampvm should show up in the list of virtual
47 machines. Before starting it, perform the following network
48 configuration sections.</li>
50 <h3>Configure the Host-Only network on virtualbox</h3>
51 <p>Configuring host-only networking for the VM makes the VM completely local
52 to your machine. The cakelampvm will not be accessible on the
53 internet or from the LAN, and can only be accessed by your host PC.</p>
55 <li> Go to virtual box "Preferences" (global preferences, not for a
57 <li> Click on the "Network" tab.</li>
58 <li> Choose the "Host-only Networks" tab from within "Network".</li>
59 <li> Click the plus icon to add a new host-only network, or if there is
60 already a Host-only network, then edit it.</li>
61 <li>Set the "Adapter" parameters:<br>
62 IPv4 Address: 10.28.42.1<br>
63 IPv4 Network Mask: 255.255.255.0<br>
64 IPv6 Address: (leave blank)<br>
65 IPv6 Prefix Length: 0<br>
66 Virtualbox will fill in the other details like so:<br>
67 <p><img alt="host only network adapter" src="images/host_only_network_adapter.png"></p>
69 <li>Set the "DHCP Server Settings" to disabled, e.g.<br>
70 <img alt="host only dhcp" src="images/host_only_adapter_dhcp_server.png"><br>
71 This is disabled because we will be using statically assigned addresses
72 for convenience and stability.</li>
74 <p>Additional information on host-only (and other) network adapter types is
75 at: https://www.virtualbox.org/manual/ch06.html#network_nat_service<br>
77 <h3>Configure the Nat Network on virtualbox</h3>
79 <li> Go to virtual box "Preferences" (global preferences, not for a
81 <li> Click on the "Network" tab.</li>
82 <li> Choose the "Nat Networks" tab from within "Network".</li>
83 <li> Click the plus icon to add a new host-only network.</li>
84 <li>Set the "NAT Network Details" parameters:<br>
85 Network Name: NatNetwork<br>
86 Network CIDR: 10.0.2.0/24<br>
87 Supports DHCP: checked<br>
88 Supports IPv6: optionally checked<br>
89 These are my settings, with IPv6 left disabled:<br>
90 <img alt="nat net config" src="images/nat_network_config.png"></li>
92 <h2>Start up the VM</h2>
93 <p>Using the virtualbox interface, you should now be able to start your
94 virtual machine. Virtualbox will complain if it detects any
95 remaining configuration problems in the VM, but it should start
96 normally. The Linux boot sequence will show many lines of text,
97 before bringing up a black console window with a login dialog.</p>
98 <p>You can log in directly on the VM console with the developer account, but
99 it is generally more useful to connect to the cakelampvm over ssh.
100 If the networking has been established properly, you should be able to do
102 <pre>ssh developer@cakelampvm.com (or equivalent with your ssh client)</pre>
103 <p>And then provide the password to log in.</p>
104 <p>A feature called "X forwarding" is enabled, so if you start graphical
105 applications on the VM, you can display them from an appropriately
106 configured host. (If you're running Linux as the host for the VM,
107 you can definitely run remote windows. Windows may not support
109 <p>#### check this!!!</p>
110 <h2>Using the guest VM's DNS services</h2>
111 <p>The cakelampvm has been set up to provide a DNS server which will answer
112 name requests for all of the sites that the VM hosts.</p>
113 <p>To use the cakelampvm DNS, modify your host operating system network
114 configuration by adding or changing the DNS server to use the guest VM's
115 DNS service. This is available at the local address
116 10.28.42.20. The DNS server can be tested with nslookup, dig and
118 <p>Note that the cakelampvm DNS should be listed first, if one intends to
119 override any DNS names that actually exist out on the internet.</p>
120 <p>If the DNS server is properly set up, then these ping commands should get
121 answering responses:</p>
122 <pre>ping cakelampvm.com</pre>
123 <pre>ping defaultcake.cakelampvm.com</pre>
124 <pre>ping mapsdemo.cakelampvm.com</pre>
125 <h3>Setting up DNS on Windows</h3>
126 <p>The ipconfig tool will provide helpful information about your current
127 networking and DNS configuration:</p>
128 <pre>ipconfig --all</pre>
129 <p>The DNS configuration on Windows is somewhat byzantine. The pipe
130 characters ('|') below are used to separate the menus or tabs or dialogs
131 to traverse. Follow this path to get to the DNS config:</p>
132 <pre>Control Panel | Network & Sharing | click WiFI or Ethernet link near top right | click Adapter Settings on left | click on specific network device to modify | select Properties</pre>
139 <h2>Editing files on the guest VM from the host</h2>
140 <p>On the host computer, look for the guest vm as a networked computer
141 called cakelampvm. This should provide some network shares using
142 Microsoft SMB protocol, and they can be attached to using the "developer"
143 user and its password.</p>
144 <p>On windows, one may want to mount this network location as a drive letter
145 for easier access.</p>
146 <p>Currently, the root of all web servers is exposed as "www". Editing
147 the files in those folders requires ownership by the developer user.
148 Currently the defaultcake server is owned by developer.</p>
149 <p>One should be able to create a new directory in the www folder owned by
150 the developer user over the network also, which can be used for creating
151 new projects. However, there is a config issue in the current vm
152 (v001) about this; to fix, run this command on the guest vm as the
154 <pre>sudo chmod g+w /var/www</pre>
155 <p>Afterwards, the www folder should allow the developer user to create new
157 <h2>Accessing files on the host PC from the guest VM</h2>
158 <p>If you want to share a folder from the host to the guest, perhaps for
159 driver updates or other conveniences, then make the share with these
162 <li>Create a folder on the host that is to be shared.</li>
163 <li>Right-click on the vm in virtualbox manager and choose "Settings".</li>
164 <li>In the "Shared Folders" tab of the settings, go to "Machine Folders".</li>
165 <li>Click the folder plus icon to create a new share.</li>
166 <li>Fill in the "Folder Path" on the host PC to the folder that will be
167 shared, and give it a name for the guest. We assume the folder
168 name will be "myshare".</li>
169 <li>On the guest vm, run the following commands to mount the share:<br>
170 <pre>mkdir ~/shared # for the guest's version of the shared folder</pre>
171 <pre>sudo mount -t vboxsf myshare ~/shared # mount the vm's share name onto the folder on the vm.</pre>
174 <h2>Adding a new website and domain on the guest VM</h2>
175 <p>To add a new website, you will need to pick one of the DNS options below
176 (A or B) depending on how you want to name the site. After the DNS
177 is updated, then follow the section after for creating a new apache conf
179 <p>Assuming one has created a new folder in "www" called "greatsite", then
180 the new web site can be brought online on the vm with one of the following
182 <h3>DNS Option A: Using a sub-domain in the cakelampvm.com domain</h3>
183 Connect to the cakelampvm via ssh as the developer user, e.g.: ssh
184 developer@cakelampvm.com
185 <p>Execute the following command to edit the DNS file for the cakelampvm
187 <pre>sudo vi /etc/bind/cakelampvm.com.conf</pre>
188 <p>Add a stanza for the new site at the end of this file:</p>
189 <pre>greatsite.cakelampvm.com IN A 10.28.42.20<br> IN HINFO "linux server" "ubuntu"</pre>
190 <p>Restart the DNS server: sudo service bind9 restart</p>
191 <p>Afterwards, pinging greatsite.cakelampvm.com should work from either the
192 guest or the host.</p>
193 <h3>DNS Option B: Using an entirely new domain for the site</h3>
194 <p>Similar procedure to above, but we will create a new file for the new
195 domain and add it to the bind directory. For this example, we will
196 create a file called /etc/bind/greatsite.tv.conf for our new domain
197 greatsite.tv with these contents:</p>
198 <pre>$TTL 1W<br>@ IN SOA @ fred.cakelampvm.com. (<br> 2017100801 ; serial<br> 2H ; refresh<br> 8M ; retry<br> 14D ; expiry<br> 6H ) ; minimum<br><br> IN NS ns.cakelampvm.com.<br> IN MX 10 mail.cakelampvm.com.<br><br># main domain for machine.<br>greatsite.tv. IN A 10.28.42.20<br> IN HINFO "linux server" "ubuntu"</pre>
199 The gnarly prefix stuff above the "greatsite.tv." listing establishes
200 configuration info for the new domain. This file relies on the
201 existing cakelampvm.com infrastructure in DNS, such as the "ns" host, which
202 is the domain's name server.
203 <p>Now that the config file is in place, edit "named.conf.local" to add the
204 new file by adding this bit of configuration at the end:</p>
205 <pre>zone "greatsite.tv" in {<br> file "/etc/bind/greatsite.tv.conf";<br> type master;<br> allow-query { any; };<br>};</pre>
206 <p>Restart the DNS server: sudo service bind9 restart</p>
207 <p>Afterwards, pinging greatsite.tv should work from either the guest or the
209 <h3>Create a new apache configuration file and load it</h3>
210 <p>Start with the following template file for the new website, and modify it
211 for the appropriate host name:</p>
212 <pre><VirtualHost *:80><br> ServerName greatsite.cakelampvm.com<br> ServerAlias greatsite.cakelampvm.com *.greatsite.cakelampvm.com<br> DocumentRoot /var/www/greatsite<br> ErrorLog ${APACHE_LOG_DIR}/greatsite.cakelampvm.com-error.log<br> CustomLog ${APACHE_LOG_DIR}/greatsite.cakelampvm.com-access.log combined<br> Alias /statistics "/var/www/webwork.repository/webwork/maps_demo/webroot/statistics"<br> Include /etc/apache2/conf-library/basic-options.conf<br> Include /etc/apache2/conf-library/rewrite-enabling.conf<br></VirtualHost></pre>
213 <p>The above example is pre-modified for DNS Option A above, the
214 greatsite.cakelampvm.com name. Switching all of those to
215 "greatsite.tv" instead would support DNS option B.</p>
216 <p>Copy that file into /etc/apache/available-sites under an appropriate
217 name, which here we will call "greatsite.conf".</p>
218 <p>Tell apache to use the new file:</p>
219 <pre>a2ensite greatsite.conf</pre>
220 <p>Finally, restart apache to get it to begin serving the site:</p>
221 <pre>sudo service apache2 restart</pre>
222 <h3>Test the new web site</h3>
223 <p>Given the configuration above, your host PC should now be able to access
225 <p>To test this, first try pinging the hostname, e.g.: ping
226 greatsite.cakelampvm.com or ping greatsite.tv</p>
227 <p>Then, if there are responses to the ping, it means the DNS is
228 working. If there are no responses, check the instructions in the
229 above DNS option section.</p>
230 <p>Once the DNS is working, one can try browsing to the site at:
231 http://greatsite.cakelampvm.com or http://greatsite.tv (depending on the
232 DNS option chosen).</p>
233 <p>If the site is not showing up properly, try examining the apache logs for
234 error messages that can be corrected. The log files are stored in
235 /var/log/apache2 and are generally named after the website.</p>
236 <h2>Configuring the guest VM</h2>
237 <p>The guest VM should already be set up appropriately. These steps
238 are provided for reference and updates.</p>
239 <h3>Set up virtualbox guest additions for the VM</h3>
240 <p>** note for v001 of cakelampvm: the below steps are still needed on the
242 <p>This procedure is needed if the guest provides an older or incompatible
243 version of the guest additions (which have already been installed on the
244 guest vm). It may also be necessary when a new version of the guest
245 additions becomes available.</p>
247 <li>To install the guest additions, open the guest VM and have its window
249 <li>Choose the "Devices" menu and select "Insert Guest Additions CD
250 Image". This will mount the CD's ISO image on the VM.</li>
251 <li>On the guest VM, it may be necessary to mount the CD image that's now
253 sudo mount /dev/sr0 /media/cdrom</li>
254 <li>Since the VM currently has no windowing system installed, one must
255 start the Guest Additions install manually:<br>
257 sudo sh VBoxLinuxAdditions.run</li>
258 <li>This should install the guest additions.</li>
260 <h3>Set up network adapters on guest VM</h3>
261 <p>The network interfaces should already be configured on the guest within
262 the virtualbox configuration. This is available by clicking on the
263 VM in the virtualbox manager and selecting "Settings". These are the
264 configuration settings used:</p>
266 Attached to: Host-only Adapter<br>
267 Name: vboxnet0 <br>
269 Attached to: Nat Network<br>
270 Name: NatNetwork</p>
271 <p>On the guest VM itself, the network settings are specified in a file
272 called /etc/network/interfaces. Here are the current contents of
274 <pre>source /etc/network/interfaces.d/*<br><br>auto lo<br>iface lo inet loopback<br><br>auto enp0s3<br>iface enp0s3 inet static<br> address 10.28.42.20<br> netmask 255.255.255.0<br> network 10.28.42.0<br> broadcast 10.28.42.255<br> dns-domain cakelampvm.com<br> dns-search cakelampvm.com<br> dns-nameservers 127.0.0.1 8.8.8.8</pre>
275 <pre>auto enp0s8</pre>
276 <pre>iface enp0s8 inet dhcp</pre>
278 <h2>Handy Techniques</h2>
279 <h3>Get the network address on the guest vm</h3>
280 <p>Run this command: ifconfig</p>
281 <p>In the results, look for "inet addr". There may be more than one,
282 if there are multiple network interfaces.</p>
283 <h3>How to cleanly reboot or shut down the guest VM</h3>
284 <p>When you've got the DNS and everything integrated, these commands will
285 manage the vm's state:</p>
286 <p>First, log into the guest VM: ssh developer@cakelampvm.com</p>
287 <p>Then, reboot the guest VM: sudo reboot</p>
288 <p>Or, halt the guest VM: sudo shutdown -h now</p>
289 <p>Using these commands is better than just cycling the power from the
290 virtualbox control panel.</p>
