5 | This distribution allows installing XWiki and every component needed for a production instance automatically. | ||
6 | |||
7 | This method works for all Debian-based linux distribution. Feel free to use [[the User Forum>>dev:Community.Discuss]] to report issues, or discuss about it. | ||
8 | |||
9 | Before you start, make sure you've checked the [[System Requirements>>platform:AdminGuide.Installation||anchor="HPrerequisites"]]. The most important step is to have a Java JRE installed. | ||
10 | |||
11 | = APT Configuration = | ||
12 | |||
13 | First, you have to configure your package manager in order to use xwiki's repository. This can be done simply, using this command: | ||
14 | |||
15 | {{code language="bash"}} | ||
16 | wget -q "https://maven.xwiki.org/public.gpg" -O- | sudo apt-key add - | ||
17 | sudo wget "https://maven.xwiki.org/stable/xwiki-stable.list" -P /etc/apt/sources.list.d/ | ||
18 | {{/code}} | ||
19 | |||
20 | {{info}} | ||
21 | Note that there is several repositories you can choose (as alternatives to the stable one you have in the previous example): | ||
22 | |||
23 | * [[https://maven.xwiki.org/releases/xwiki-releases.list]]: all released versions including milestones and release candidates (beta) | ||
24 | * [[https://maven.xwiki.org/stable/xwiki-stable.list]]: all released versions excluding milestones and release candidates (stable) | ||
25 | * [[https://maven.xwiki.org/lts/xwiki-lts.list]]: the current "long term support" branch versions as defined in [[Support page>>xwiki:Main.Support]] | ||
26 | {{/info}} | ||
27 | |||
28 | Now you can update the packages database to read the data from this repository. | ||
29 | |||
30 | {{code language="bash"}} | ||
31 | sudo apt-get update | ||
32 | {{/code}} | ||
33 | |||
34 | {{info}} | ||
35 | I'll assume you're using APT tools. You can use Aptitude as well. | ||
36 | {{/info}} | ||
37 | |||
38 | Now you can make a little search to see what this repo offers. | ||
39 | |||
40 | {{code language="bash"}} | ||
41 | apt-cache search xwiki | ||
42 | {{/code}} | ||
43 | |||
44 | It shows the following packages (the exact list depends on the version the repository contains): | ||
45 | |||
46 | * xwiki-common - XWiki, you can install this if you want to take care yourself of the database and application server | ||
47 | * xwiki-mysql-common - XWiki MySQL common package, you can install this if you want to take care yourself of the application server | ||
48 | * xwiki-pgsql-common - XWiki PostgreSQL common package, you can install this if you want to take care yourself of the application server | ||
49 | * xwiki-tomcat7-common - XWiki Tomcat 7 common package, you can install this if you want to take care yourself of the database link | ||
50 | * xwiki-tomcat8-common - XWiki Tomcat 8 common package, you can install this if you want to take care yourself of the database link | ||
51 | * xwiki-tomcat9-common - XWiki Tomcat 9 common package, you can install this if you want to take care yourself of the database link | ||
52 | * xwiki-tomcat7-mysql - XWiki Tomcat 7/MySQL based package | ||
53 | * xwiki-tomcat8-mysql - XWiki Tomcat 8/MySQL based package | ||
54 | * xwiki-tomcat9-mysql - XWiki Tomcat 9/MySQL based package | ||
55 | * xwiki-tomcat7-pgsql - XWiki Tomcat 7/PostgreSQL | ||
56 | * xwiki-tomcat8-pgsql - XWiki Tomcat 8/PostgreSQL | ||
57 | * xwiki-tomcat9-pgsql - XWiki Tomcat 9/PostgreSQL | ||
58 | * xwiki-solr-data - A pre configured Solr core to be used to setup a standalone instance of Solr for XWiki | ||
59 | |||
60 | Plus legacy packages from older versions of XWiki like xwiki-enterprise-* packages. | ||
61 | |||
62 | {{error}} | ||
63 | xwiki-enterprise-* packages were deprecated as of 9.4. Installations requiring those packages will appear to have stopped updating at version 9.4. Install the corresponding xwiki-* package to update to the latest version. (For example, if you were relying on the xwiki-enterprise-tomcat8-mysql package, you will now need to install the xwiki-tomcat8-mysql package.) | ||
64 | {{/error}} | ||
65 | |||
66 | {{info}} | ||
67 | According to selection, package manager will install all necessary dependencies (application server, database, Java runtime). If you haven't installed these packages before, package manager can ask additional info from you. | ||
68 | {{/info}} | ||
69 | |||
70 | {{warning}} | ||
71 | On Ubuntu you will need [[##universe## repository>>https://help.ubuntu.com/community/Repositories/CommandLine]] to install Tomcat packages. It's generally enabled by default. | ||
72 | {{/warning}} | ||
73 | |||
74 | = Java 8 = | ||
75 | |||
76 | XWiki require Java 8 since XWiki 8.1, **OpenJDK 8** will be automatically installed as dependency on recent distributions. | ||
77 | |||
78 | {{warning}} | ||
79 | In some cases Java 11 might be installed and activated by default. If you have both Java version (8 and 11) in your distribution, you can modify ##/etc/default/tomcat8## to point to a java8 JAVA_HOME | ||
80 | {{/warning}} | ||
81 | |||
82 | For some older distributions the problem is that Ubuntu and Debian did not bothered put OpenJDK 8 on older but still supported distributions default repositories (for example Ubuntu 14.04 or Debian Wheezy/Jessie). For those you will have to make sure there is some repository with it so that Java 8 is installed as a package so that XWiki find it as dependency. | ||
83 | |||
84 | Also if you have several versions of Java installed you might need to explicitly tell Tomcat which one to use after the install. See [[Tomcat Usability section>>||anchor="HJavaVersion"]]. | ||
85 | |||
86 | Here is a few helpers for specific distributions: | ||
87 | |||
88 | == Ubuntu 14.04 (Trusty Tahr), Debian < 9 == | ||
89 | |||
90 | * AdoptOpenJDK provide a Debian repository to install OpenJDK, see https://adoptopenjdk.net/installation.html#linux-pkg | ||
91 | |||
92 | = Complete Installation = | ||
93 | |||
94 | {{warning}} | ||
95 | Most Debian distributions provide a Tomcat package with a pretty low Memory setting by default (128MB) and this need to be increased for XWiki to fully work. See [[Tomcat Usability section>>||anchor="HTomcatUsability"]] for more details. | ||
96 | {{/warning}} | ||
97 | |||
98 | == Using MySQL == | ||
99 | |||
100 | You only have to run this command to install all the interesting components. | ||
101 | |||
102 | {{code language="bash"}} | ||
103 | sudo apt-get install xwiki-tomcat9-mysql | ||
104 | {{/code}} | ||
105 | |||
106 | This package depends on xwiki-common, xwiki-tomcat9-common, xwiki-mysql-common, mysql-server, tomcat9 and libmysql-java. You might have to select a different version of Tomcat depending on what's available in your system repository. | ||
107 | |||
108 | During the installation, you may have some questions from dbconfig, in charge of the configuration of the database. Don't confuse it with the MySQL root password prompt, which beg you to put a password for the superuser. | ||
109 | DBconfig prompt is about the configuration of xwiki and mysql. If you haven't any mysql already installed and you aren't familiar with it, you should let dbconfig handle this. | ||
110 | |||
111 | DBconfig is then asking you for the mysql root password (you may have entered before). Then, you can choose the password for the "xwiki" mysql user. This user will be used to connect from XWiki application. Choose it wisely, but you don't have to pay a lot of attention to it, because after that, dbconfig is configuring XWiki automatically with these credentials. | ||
112 | |||
113 | The installation now ends, with the automatic start of tomcat daemon ("Starting Tomcat servlet engine tomcat9 [OK]"). | ||
114 | |||
115 | {{warning}} | ||
116 | Note that your wiki is absolutely empty, like a WAR installation. Distribution Wizard will take care of the rest. | ||
117 | {{/warning}} | ||
118 | |||
119 | == Using PostgreSQL == | ||
120 | |||
121 | It's as simple as the MySQL installation, you only need to choose the right virtual package. | ||
122 | |||
123 | {{code language="bash"}} | ||
124 | sudo apt-get install xwiki-tomcat8-pgsql | ||
125 | {{/code}} | ||
126 | |||
127 | After you've made sure to update the memory settings (see below), you can now point your favorite browser to the following URL to use your wiki: ##http:~/~/localhost:8080/xwiki## | ||
128 | |||
129 | PostgreSQL is slightly different than MySQL in the handling of databases and in the manual configuration, but everything should work on the first try. | ||
130 | |||
131 | == Security settings == | ||
132 | |||
133 | 1. ((( | ||
134 | Open ##/etc/xwiki/xwiki.cfg## file and change lines: | ||
135 | |||
136 | {{code language="none"}} | ||
137 | ... | ||
138 | #-# Cookie encryption keys. You SHOULD replace these values with any random string, | ||
139 | #-# as long as the length is the same. | ||
140 | xwiki.authentication.validationKey=your1stkeyhere | ||
141 | xwiki.authentication.encryptionKey=your2ndkeyhere | ||
142 | ... | ||
143 | {{/code}} | ||
144 | ))) | ||
145 | 1. ((( | ||
146 | If you need, add password to the built-in superadmin account, by changing line: | ||
147 | |||
148 | {{code language="none"}} | ||
149 | ... | ||
150 | #-# Enable to allow superadmin. It is disabled by default as this could be a | ||
151 | #-# security breach if it were set and you forgot about it. Should only be enabled | ||
152 | #-# for recovering the Wiki when the rights are completely messed. | ||
153 | xwiki.superadminpassword=yourpassword | ||
154 | ... | ||
155 | {{/code}} | ||
156 | ))) | ||
157 | |||
158 | == Tomcat Usability == | ||
159 | |||
160 | You can find various generic advices and troubleshooting related to Tomcat on https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/InstallationWAR/InstallationTomcat/. | ||
161 | |||
162 | === Java Version === | ||
163 | |||
164 | Make sure Tomcat is executed with the right [[Java version>>platform:AdminGuide.Installation||anchor="HHardwareandSoftwarerequirements"]]. | ||
165 | |||
166 | This is usually indicated in the file ##/etc/default/tomcat8## (or ##/etc/default/tomcat7## for Tomcat 7, etc). | ||
167 | |||
168 | === Memory === | ||
169 | |||
170 | The default Tomcat memory setup is too low for XWiki's needs. | ||
171 | |||
172 | You can change it in the file ##/etc/default/tomcat8## (or ##/etc/default/tomcat7## for Tomcat 7, etc). | ||
173 | |||
174 | Modify the property ##JAVA_OPTS##. For example: | ||
175 | |||
176 | {{code language="none"}} | ||
177 | JAVA_OPTS="-Djava.awt.headless=true -Xmx1024m" | ||
178 | {{/code}} | ||
179 | |||
180 | You should [[check the Memory settings we recommend>>platform:AdminGuide.Performances||anchor="HMemory"]]. | ||
181 | |||
182 | === /dev/urandom === | ||
183 | |||
184 | In most Debian-based systems the default random implementation is ##/dev/random## which can be very slow. ##/dev/urandom## is much faster and it's fine for XWiki's needs so you should use it when possible: | ||
185 | |||
186 | * edit ##/etc/default/tomcat8## file and add | ||
187 | |||
188 | {{code language="bash"}} | ||
189 | JAVA_OPTS="${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom" | ||
190 | {{/code}} | ||
191 | |||
192 | = Concluding Step = | ||
193 | |||
194 | {{include reference="Documentation.AdminGuide.Installation.InstallationConcludingSteps.WebHome"/}} | ||
195 | |||
196 | = Uninstallation = | ||
197 | |||
198 | If you want to remove XWiki from your system, you only have to uninstall the package you've installed at the beginning of this documentation. For example: | ||
199 | |||
200 | {{code language="bash"}} | ||
201 | sudo apt-get --purge remove xwiki-common | ||
202 | {{/code}} | ||
203 | |||
204 | Attention, these commands do not remove MySQL/PostgreSQL nor Tomcat from your system. To do so, if you don't use these applications for another purpose, you can make some cleaning with | ||
205 | |||
206 | {{code language="bash"}} | ||
207 | sudo apt-get --purge autoremove | ||
208 | {{/code}} | ||
209 | |||
210 | = Troubleshooting = | ||
211 | |||
212 | == Tomcat == | ||
213 | |||
214 | See [[Tomcat Installation>>platform:AdminGuide.InstallationTomcat||anchor="HTroubleshooting"]] for generic Tomcat related issues. | ||
215 | |||
216 | === Ubuntu 16.04 (Xenial Xerus) === | ||
217 | |||
218 | At time of writing the version of Tomcat provide by Ubuntu 16.04 repository has a serious classloader related bug which makes impossible to use code macro or write Python scripts in XWiki. See https://bugs.launchpad.net/ubuntu/+source/tomcat8/+bug/1644144 and https://forum.xwiki.org/t/code-macro-requirements/909/20 for some more detailed explanations and workarounds. | ||
219 | |||
220 | {{code language="bash"}} | ||
221 | sudo add-apt-repository ppa:nacc/tomcat8v2 | ||
222 | sudo apt-get update | ||
223 | sudo apt-get install tomcat8=8.0.32-1ubuntu1.3~ppa2 | ||
224 | sudo apt-get install tomcat8-common=8.0.32-1ubuntu1.3~ppa2 | ||
225 | sudo apt-get install libtomcat8-java=8.0.32-1ubuntu1.3~ppa2 | ||
226 | sudo service tomcat8 restart | ||
227 | {{/code}} | ||
228 | |||
229 | Don't hesitate to click on "This bug affects me" on launchpad page if it's still not fixed, might help speeding up things... | ||
230 | |||
231 | == MySQL == | ||
232 | |||
233 | See [[MySQL Installation>>platform:AdminGuide.InstallationMySQL||anchor="HTroubleshooting"]] for generic MySQL related issues. | ||
234 | |||
235 | == PostgreSQL == | ||
236 | |||
237 | See [[PostgreSQL Installation>>platform:AdminGuide.InstallationPostgreSQL||anchor="HTroubleshooting"]] for generic PostgreSQL related issues. | ||
238 | |||
239 | === Bad version of PostgreSQL driver on Debian Wheezy === | ||
240 | |||
241 | The version of the PostgreSQL driver on Debian Wheezy is the 9.1 (at least when writing those lines) which does not work well with XWiki. You will have to upgrade it. | ||
242 | |||
243 | The latest JDBC postgres driver is available at https://jdbc.postgresql.org/download.html , at the time of this writing, the latest version is postgresql-9.4-1201.jdbc41.jar (which works fine with xwiki), you need to download the driver to your server, a good place is where the other drivers are: /usr/share/java, then remove the symlink postgresql-jdbc4.jar and replace it by one to the new driver: | ||
244 | |||
245 | {{code}} | ||
246 | wget -O /usr/share/java/postgresql-9.4-1201.jdbc41.jar https://jdbc.postgresql.org/download/postgresql-9.4-1201.jdbc41.jar | ||
247 | rm /usr/share/java/postgresql-jdbc4.jar | ||
248 | ln -s /usr/share/java/postgresql-9.4-1201.jdbc41.jar /usr/share/java/postgresql-jdbc4.jar | ||
249 | {{/code}} | ||
250 | |||
251 | Restart tomcat and you will not have any issue with the JDBC driver. | ||
252 | |||
253 | == XWiki won't start and I get Solr related error(s) in the log == | ||
254 | |||
255 | There is no automatic migration of Solr schema and it changes from time to time. The simplest fix in such case is usually to stop Tomcat, delete the folder ##/var/lib/xwiki/data/solr## and restart Tomcat. XWiki will automatically create a new one and start indexing the wiki. | ||
256 | |||
257 | {{code language="bash"}} | ||
258 | sudo /etc/init.d/tomcat8 stop | ||
259 | rm -rf /var/lib/xwiki/data/solr | ||
260 | sudo /etc/init.d/tomcat8 start | ||
261 | {{/code}} | ||
262 | |||
263 | = Other useful info = | ||
264 | |||
265 | == XWiki as root webapp (short URLs) == | ||
266 | |||
267 | {{warning}} | ||
268 | When doing it make sure to check after upgrade if all is OK in /etc/tomcat8/Catalina/localhost folder (xwiki.xml might be restored). | ||
269 | {{/warning}} | ||
270 | |||
271 | * Rename file ##/etc/tomcat7/Catalina/localhost/xwiki.xml## into ##/etc/tomcat8/Catalina/localhost/ROOT.xml## | ||
272 | * Edit file ##/etc/xwiki/xwiki-tomcat8.xml## (or ##/etc/xwiki/xwiki-tomcat7.xml## depending on your tomcat version) and modify ##Context## XML element path from ##/xwiki## to ##/## as in moving from((( | ||
273 | {{code language="xml"}} | ||

289 | * Edit file ##/etc/xwiki/xwiki.cfg## and uncomment {{code language="properties"}}xwiki.webapppath={{/code}} | ||
290 | |||
291 | Note that this is only the part of Short URL which is specific to the Debian setup, for the rest you will have to look at [[the generic documentation>>doc:Documentation.AdminGuide.ShortURLs.WebHome]]. | ||
292 | |||
293 | == Integrate with LibreOffice == | ||
294 | |||
295 | Install libreoffice with {{code language="none"}}sudo apt-get install libreoffice{{/code}}. | ||
296 | |||
297 | And setup XWiki to automatically start and access libreoffice in ##/etc/xwiki/xwiki.properties##: | ||
298 | |||
299 | {{code language="properties"}} | ||
300 | openoffice.autoStart=true | ||
