Thomas Mortagne 120.1 9 = APT Configuration =
Guillaume Fenollar 1.1 10
Thomas Mortagne 196.3 11 First, you have to configure your package manager in order to use XWiki's repository. This can be done simply, using this command:
Guillaume Fenollar 1.1 12
Thomas Mortagne 18.1 13 {{code language="bash"}}
Thomas Mortagne 209.1 14 sudo wget https://maven.xwiki.org/xwiki-keyring.gpg -O /usr/share/keyrings/xwiki-keyring.gpg
15 sudo wget "https://maven.xwiki.org/stable/xwiki-stable.list" -O /etc/apt/sources.list.d/xwiki-stable.list
Guillaume Fenollar 1.1 16 {{/code}}
17
Thomas Mortagne 44.1 18 {{info}}
19 Note that there is several repositories you can choose (as alternatives to the stable one you have in the previous example):
Thomas Mortagne 112.1 20
Jean-Sébastien Dennebouy 198.1 21 * [[https:~~/~~/maven.xwiki.org/releases/xwiki-releases.list>>https://maven.xwiki.org/releases/xwiki-releases.list]]: all released versions including milestones and release candidates (beta)
22 * [[https:~~/~~/maven.xwiki.org/stable/xwiki-stable.list>>https://maven.xwiki.org/stable/xwiki-stable.list]]: all released versions excluding milestones and release candidates (stable)
23 * [[https:~~/~~/maven.xwiki.org/lts/xwiki-lts.list>>https://maven.xwiki.org/lts/xwiki-lts.list]]: the current "long term support" branch versions as defined in [[Support page>>xwiki:Main.Support]]
Thomas Mortagne 44.1 24 {{/info}}
25
Guillaume Fenollar 1.1 26 Now you can update the packages database to read the data from this repository.
27
Thomas Mortagne 18.1 28 {{code language="bash"}}
29 sudo apt-get update
30 {{/code}}
31
Guillaume Fenollar 1.1 32 Now you can make a little search to see what this repo offers.

Thomas Mortagne 18.1 34 {{code language="bash"}}
Guillaume Fenollar 1.1 35 apt-cache search xwiki
36 {{/code}}
37
Thomas Mortagne 54.1 38 It shows the following packages (the exact list depends on the version the repository contains):
Guillaume Fenollar 2.1 39

Craig Wright 117.1 59 {{error}}
Thomas Mortagne 207.1 60 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.)

Guillaume Fenollar 1.1 72
Thomas Mortagne 64.1 73 {{warning}}
Thomas Mortagne 89.1 74 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.

Thomas Mortagne 190.1 77 == Using MariaDB ==
Guillaume Fenollar 1.1 78
Thomas Mortagne 188.1 79 {{warning}}
Thomas Mortagne 199.1 80 Note that XWiki require at least MariaDB 10.2. If your Debian distribution provide an older version (like Debian Stretch/9) you can use the one from the repositories provided by the MariaDB project to get a more recent version on https://downloads.mariadb.org/mariadb/repositories/.
Thomas Mortagne 188.1 81 {{/warning}}
Thomas Mortagne 185.1 82
Thomas Mortagne 196.4 83 The following will install everything you need to run XWiki with MariaDB and Tomcat 9:
Guillaume Fenollar 1.2 84
Thomas Mortagne 18.1 85 {{code language="bash"}}
Thomas Mortagne 190.1 86 sudo apt-get install xwiki-tomcat9-mariadb
Thomas Mortagne 18.1 87 {{/code}}
88
Thomas Mortagne 190.1 89 This package depends on xwiki-common, xwiki-tomcat9-common, xwiki-mariadb-common, mariadb-server and tomcat9. You might have to select a different version of Tomcat depending on what's available in your system repository.
Guillaume Fenollar 1.2 90
Thomas Mortagne 190.1 91 During the installation, you may have some questions from dbconfig, in charge of the configuration of the database. Don't confuse it with the MariaDB root password prompt, which beg you to put a password for the superuser.
92 DBconfig prompt is about the configuration of xwiki and mariadb. If you haven't any mariadb already installed and you aren't familiar with it, you should let dbconfig handle this.
Guillaume Fenollar 3.1 93
Thomas Mortagne 190.1 94 DBconfig is then asking you for the mariadb root password (you may have entered before). Then, you can choose the password for the "xwiki" mariadb 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.
Guillaume Fenollar 1.2 95
Thomas Mortagne 149.1 96 The installation now ends, with the automatic start of tomcat daemon ("Starting Tomcat servlet engine tomcat9 [OK]").
Guillaume Fenollar 2.1 97
Guillaume Fenollar 3.1 98 {{warning}}

Thomas Mortagne 190.1 105 Note that XWiki require at least MySQL 5.7. This package also works with MariaDB (in which case you need at least MariaDB 10.2).

Thomas Mortagne 169.1 112 {{/code}}
113
Thomas Mortagne 190.1 114 This package depends on xwiki-common, xwiki-tomcat9-common, xwiki-mysql-common, mysql-server and tomcat9. You might have to select a different version of Tomcat depending on what's available in your system repository.

Thomas Mortagne 142.1 169
Thomas Mortagne 78.1 170 === Java Version ===
171
Vincent Massol 105.3 172 Make sure Tomcat is executed with the right [[Java version>>platform:AdminGuide.Installation||anchor="HHardwareandSoftwarerequirements"]].
Thomas Mortagne 78.1 173
Thomas Mortagne 172.1 174 This is usually indicated in the file ##/etc/default/tomcat9## (or ##/etc/default/tomcat8## for Tomcat 8, etc).
Thomas Mortagne 78.1 175
176 === Memory ===
177
Vincent Massol 119.2 178 The default Tomcat memory setup is too low for XWiki's needs.
Guillaume Fenollar 11.1 179
Thomas Mortagne 172.1 180 You can change it in the file ##/etc/default/tomcat9## (or ##/etc/default/tomcat8## for Tomcat 8, etc).
Guillaume Fenollar 11.1 181
Thomas Mortagne 71.1 182 Modify the property ##JAVA_OPTS##. For example:
Thomas Mortagne 18.1 183
Thomas Steinbach 25.1 184 {{code language="none"}}
Thomas Mortagne 94.1 185 JAVA_OPTS="-Djava.awt.headless=true -Xmx1024m"

191
Thomas Mortagne 144.1 192 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:

Guillaume Fenollar 4.1 205
Guillaume Fenollar 10.1 206 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:

Jean-Sébastien Dennebouy 198.1 222 == No package can be found for Java ==
Thomas Mortagne 196.3 223
Thomas Mortagne 208.1 224 XWiki require at least Java 8 since XWiki 8.1 and Java 11 since XWiki 14.0, **OpenJDK 11** (the recommended version) will be automatically installed as dependency on recent distributions.

Thomas Mortagne 126.1 235
Thomas Mortagne 205.1 236 In some Debian/Ubuntu versions a broken accessibility option is enabled by default on Java 8 and it's what is causing this error. See https://jira.xwiki.org/browse/XWIKI-16993 and https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/935296 for more details.
