44d5d40a 70#### 1.3.c. FreeBSD 10
3425beb7 71There are 3 different ways how you can install RackTables and its dependencies on FreeBSD.
72
44d5d40a 73######A. use pkg (Binary Package Management) (not always the newest version)
3425beb7 74```
75# pkg install racktables
76# pkg install mod_php56 mysql56-server
77```
44d5d40a 78As of March 2017 this will install RackTables Version 0.20.11 and its dependencies (php 5.6, mysql-server 5.6 and apache 2.4).
3425beb7 79
44d5d40a 80######B. use the ports system (possibly more recent than pkg)
3425beb7 81```
82# cd /usr/ports/sysutils/racktables
83# make install
84# pkg install mod_php56 mysql56-server
85```
44d5d40a 86As of March 2017 this will install RackTables Version 0.20.11 and build and install its dependencies (php 5.6, mysql-server 5.6 and apache 2.4).
3425beb7 87
44d5d40a 88######C. manual (newest version)
3425beb7 89Install dependencies with pkg:
90```
91# pkg install php70-bcmath php70-curl php70-filter php70-gd php70-gmp php70-json php70-mbstring php70-openssl php70-pdo php70-pdo_mysql php70-session php70-simplexml php70-snmp php70-sockets
510ae82b 92# pkg install mod_php70 mysql56-server
3425beb7 93```
94
44d5d40a 95unpack tar.gz/zip archive to `/usr/local/www`
3425beb7 96
22b1da4a 97symlink racktables dir
3425beb7 98```
99# cd /usr/local/www
100# ln -s RackTables-0.20.xx racktables
101```
102
103##### Common install steps
104Apache users should create a racktables.conf file under their apache
105Includes directory with the following contents:
106```
107AddType application/x-httpd-php .php
108AddType application/x-httpd-php-source .phps
109
110<Directory /usr/local/www/racktables/wwwroot>
111 DirectoryIndex index.php
112 Require all granted
113</Directory>
114Alias /racktables /usr/local/www/racktables/wwwroot
115```
116
117Start services:
118```
119#echo 'apache24_enable="YES"' >> /etc/rc.conf
120#service apache24 start
121
122#echo 'mysql_enable="YES"' >> /etc/rc.conf
123#service mysql-server start
124```
125
0ed66a4d 126Browse to http://address.to.your.server/racktables/index.php and follow the instructions.
3425beb7 127
44d5d40a 128Note: set `secret.php` permissions when prompted.
3425beb7 129```
130# chown www:www /usr/local/www/racktables/wwwroot/inc/secret.php
131# chmod 400 /usr/local/www/racktables/wwwroot/inc/secret.php
132```
133
134
fde823aa 135## 2. Copy the files
2797f2c7
DO
136Unpack the tar.gz/zip archive to a directory of your choice and configure Apache
137httpd to use `wwwroot` subdirectory as a new DocumentRoot. Alternatively,
138symlinks to `wwwroot` or even to `index.php` from an existing DocumentRoot are
35d895be 139also possible and often advisable (see `README.Fedora`).
2797f2c7 140
fde823aa 141## 3. Run the installer
2797f2c7
DO
142Open the configured RackTables URL and you will be prompted to configure
143and initialize the application.

2797f2c7
DO
154
1550. **Backup your database** and check the release notes below before actually
156 starting the upgrade.
1571. Remove all existing files except configuration (the `inc/secret.php` file)
158 and local plugins (in the `plugins/` directory).
1592. Put the contents of the new tar.gz/zip archive into the place.
1603. Open the RackTables page in a browser. The software will detect version
161 mismatch and display a message telling to log in as admin to finish
162 the upgrade.
1634. Do that and report any errors to the bug tracker or the mailing list.

178
d40d136a 179New `IPV4_TREE_SHOW_UNALLOCATED` configuration option introduced to disable
c5c39ee5 180dsplaying unallocated networks in IPv4 space tree. Setting it also disables
e1e193fe 181the "knight" feature.
c5c39ee5 182

DO
183### Upgrading to 0.20.7
184
185From now on the minimum (oldest) release of PHP that can run RackTables is
1865.2.10. In particular, to continue running RackTables on CentOS 5 it is
187necessary to replace its php* RPM packages with respective php53* packages
188before the upgrade (except the JSON package, which PHP 5.3 provides internally).
189
190Database triggers are used for some data consistency measures. The database
191user account must have the 'TRIGGER' privilege, which was introduced in
192MySQL 5.1.7.
193
d32264dc 194The `IPV4OBJ_LISTSRC` configuration option is reset to an expression that enables
2797f2c7
DO
195the IP addressing feature for all object types except those listed.
196
197Tags could now be assigned on the Edit/Properties tab using a text input with
198auto-completion. Type a star '*' to view full tag tree in auto-complete menu.
199It is worth to add the following line to the permissions script if the
200old-fashioned 'Tags' tab is not needed any more:
201```
202 deny {$tab_tags} # this hides 'Tags' tab
203```
204
205This release converts collation of all DB fields to the `utf8_unicode_ci`. This
206procedure may take some time, and could fail if there are rows that differ only
207by letter case. If this happen, you'll see the failed SQL query in upgrade report
208with the "Duplicate entry" error message. Feel free to continue using your
209installation. If desired so, you could eliminate the case-duplicating rows
210and re-apply the failed query.
211
212### Upgrading to 0.20.6
213
214New `MGMT_PROTOS` configuration option replaces the `TELNET_OBJS_LISTSRC`,
215`SSH_OBJS_LISTSRC` and `RDP_OBJS_LISTSRC` options (converting existing settings as
216necessary). `MGMT_PROTOS` allows to specify any management protocol for a
217particular device list using a RackCode filter. The default value
218(`ssh: {$typeid_4}, telnet: {$typeid_8}`) produces `ssh://server.fqdn` for
219servers and `telnet://switch.fqdn` for network switches.
220
221### Upgrading to 0.20.5
222
223This release introduces the VS groups feature. VS groups is a new way to store
224and display virtual services configuration. There is a new "ipvs" (VS group)
225realm. All previously existing VS configuration remains functional and user
226is free to convert it to the new format, which displays it in a more natural way
227and allows to generate virtual_server_group keepalived configs. To convert a
228virtual service to the new format, it is necessary to manually create a VS group
229object and assign IP addresses to it. The VS group will display a "Migrate" tab
230to convert the old-style VS objects, which can be removed after a successful
231conversion.
232
233The old-style VS configuration becomes **deprecated**. Its support will be removed
234in a future major release. So it is strongly recommended to convert it to the
235new format.
236
237### Upgrading to 0.20.4
238
239Please note that some dictionary items of Cisco Catalyst 2960 series switches
240were renamed to meet official Cisco classification:
241
242old name | new name
243------------|---------
2442960-48TT | 2960-48TT-L
2452960-24TC | 2960-24TC-L

251C2960-24 | C2960-24-S
252C2960G-24PC | C2960-24PC-L
253
254The `DATETIME_FORMAT` configuration option used in setting date and time output
255format now uses a [different](http://php.net/manual/en/function.strftime.php)
256syntax. During upgrade the option is reset to
257the default value, which is now %Y-%m-%d (YYYY-MM-DD) per ISO 8601.
258
259This release intoduces two new configuration options:
260`REVERSED_RACKS_LISTSRC` and `NEAREST_RACKS_CHECKBOX`.
261
262### Upgrading to 0.20.1
263
d32264dc 264The 0.20.0 release includes a bug that breaks IP networks' capacity displaying on
2797f2c7
DO
26532-bit architecture machines. To fix this, this release makes use of PHP's BC
266Math module. It is a new reqiurement. Most PHP distributions have this module
267already enabled, but if yours does not - you need yo recompile PHP.
268
269Security context of 'ipaddress' page now includes tags from the network
270containing an IP address. This means that you should audit your permission rules
271to check there is no unintended allows of changing IPs based on network's
272tagset. Example:
273```
274 allow {client network} and {New York}
275```
276This rule now not only allows any operation on NY client networks, but also any
277operation with IP addresses included in those networks. To fix this, you should
278change the rule this way:
279```
280 allow {client network} and {New York} and not {$page_ipaddress}
281```
282
283### Upgrading to 0.20.0
284
285WARNING: This release have too many internal changes, some of them were waiting
286more than a year to be released. So this release is considered "BETA" and is
287recommended only to curiuos users, who agree to sacrifice the stability to the
288progress.
289
290Racks and Rows are now stored in the database as Objects. The RackObject table
291was renamed to Object. SQL views were created to ease the migration of custom
292reports and scripts.
293
294New plugins engine instead of `local.php` file. To make your own code stored in
295`local.php` work, you must move the `local.php` file into the `plugins/` directory.
296The name of this file does not matter any more. You also can store multiple
297files in that dir, separate your plugins by features, share them and try the
298plugins from other people just placing them into `plugins/` dir, no more merging.
299
300* `$path_to_local_php` variable has no special meaning any more.
301* `$racktables_confdir` variable is now used only to search for `secret.php` file.
302* `$racktables_plugins_dir` is a new overridable special variable pointing to `plugins/` directory.
303
304Beginning with this version it is possible to delete IP prefixes, VLANs, Virtual
305services and RS pools from within theirs properties tab. So please inspect your
306permissions rules to assure there are no undesired allows for deletion of these
307objects. To ensure this, you could try this code in the beginning of permissions
308script:
309```
310allow {userid_1} and {$op_del}
311deny {$op_del} and ({$tab_edit} or {$tab_properties})
312```
313
314Hardware gateways engine was rewritten in this version of RackTables. This means
315that the file `gateways/deviceconfig/switch.secrets.php` is not used any more. To
316get information about configuring connection properties and credentials in a new
317way please read [this](http://wiki.racktables.org/index.php/Gateways).
318
319This also means that recently added features based on old API (D-Link switches
320and Linux gateway support contributed by Ilya Evseev) are not working any more
321and waiting to be forward-ported to new gateways API. Sorry for that.
322
323Two new config variables appeared in this version:
d32264dc 324 - `SEARCH_DOMAINS`. Comma-separated list of DNS domains that are considered
2797f2c7 325 "base" for your network. If RackTables search engine finds multiple objects
d32264dc 326 based on your search input, but there is only one that has FQDN consisting of
2797f2c7
DO
327 your input and one of these search domains, you will be redirected to this
328 object and other results will be discarded. Such behavior was unconditional
329 since 0.19.3, which caused many objections from users. So welcome this
330 config var.
331 - `QUICK_LINK_PAGES`. Comma-separated list of RackTables pages to display links
332 to them on top. Each user could have his own list.
333
334Also some of config variables have changed their default values in this version.
335This means that upgrade script will change their values if you have them in
336previous default state. This could be inconvenient, but it is the most effective
337way to encourage users to use new features. If this behavior is not what you
338want, simply revert these variables' values:
339
340variable | old | new | comment
341------------------------|-------------|-------|--------
342`SHOW_LAST_TAB` | no | yes
343`IPV4_TREE_SHOW_USAGE` | yes | no | Networks' usage is still available by click.
344`IPV4LB_LISTSRC` | {$typeid_4} | false
345`FILTER_DEFAULT_ANDOR` | or | and | This implicitly enables the feature of dynamic tree shrinking.
346`FILTER_SUGGEST_EXTRA` | no | yes | Yes, we have extra logical filters!
347`IPV4_TREE_RTR_AS_CELL` | yes | no | Display routers as simple text, not cell.
348
349Also please note that variable `IPV4_TREE_RTR_AS_CELL` now has third special value
350besides 'yes' and 'no': 'none'. Use 'none' value if you are experiencing low
351performance on IP tree page. It will completely disable IP ranges scan for
352used/spare IPs and the speed of IP tree will increase radically. The price is
353you will not see the routers in IP tree at all.
