File and Folder permissions

If your server is unhappy with Tiki file and folder permissions (this is dependent on server configuration), you may get an error message or blank pages. These failed attempts are typically in the error log (ask your web host to know where they are as it's different depending of your setup)

Too few permissions
If a message appears indicating that specific directories are not writable, you will need to change the permissions on the indicated directories. Tiki will attempt to verify that it can read (and write) to all necessary directories. This error message will include instructions about how to resolve the issue.

Too many permissions
If you are getting Internal Server Error 500, blank pages or similar, it could be that the permissions on the files are not appropriate for your webhost.

If your permissions are currently at "777", use your FTP client to change the files to "755". If Tiki is installed in a directory, make sure to also change the permission of the folder which contains the tiki files.

If you have shell access, you can run:

sh setup.sh

and answer any questions. If you don't know what to answer, just click "enter" to keep the defaults.

root@yourserver:/var/www/tiki# sh setup.sh

 Tiki setup.sh - your options
 ============================

Composer: If you are installing via a released Tiki package (zip, tar.gz, tar.bz2, 7z), you can and should skip using Composer. If you are installing and upgrading via SVN, you need to run Composer after 'svn checkout' and 'svn upgrade'. More info at https://dev.tiki.org/Composer
  
 c run composer and exit (recommended to be done first)

For all Tiki instances (via SVN or via a released package):

 f fix file & directory permissions (classic default)          o open file and directory permissions (classic option)
 S clear screen

Your choice [f]?


The option preselected in "Our choice" will initially be "c", to run "composer" script and get the required php dependencies for you. and in a second step, it will suggest "f", to fix file and directory permissions (classic default option). You can choose at any time the letter that best suits your needs, among the options offered.

If "sh setup.sh" doesn't work for you, you may try, in your ./tiki/ directory

chmod -R 777 ./db ./dump ./img/wiki ./img/wiki_up ./img/trackers ./modules/cache ./temp ./temp/cache ./temp/templates_c ./templates ./styles ./whelp/

Another way is to set permissions for all directories and then set permissions for all files. For example, to set the permissions for all directories to 777 and the permissions for all files to 644, use the following separate commands through shell access:

find [YOURDIR] -type d -exec chmod 777 {} \;

find [YOURDIR] -type f -exec chmod 644 {} \;

After correcting any directory or file permission problems, visit tiki-install.php to continue.

SuPHP Problems

Systems with SuPHP need permissions 755 at maximum. Group must not be allowed to write. This includes the complete path in the filesystem, not only document root of the webserver. Wrong permissions may lead to 500 Internal Server Error here. On the other hand less permissions (namely 750 without x/execute/subdir entry for webserver) may lead to 403 Forbidden Error.

1.1.3. Permission Matrix

Several usecases and minimum to maximum permissions you may try if something doesn't work properly. Permissions refer to data directly accessed by the webserver (files included by Tiki itself may and should have less permissions):

Ownership
username:groupname
no SuPHP
files / subdirectories
with SuPHP
files / subdirectories
webserver:webserver
600 - 666 / 700 - 777
?
user:user
604 - 666 / 705 - 777
600 - 644 / 701 - 755
user:webserver
660 - 666 / 770 - 777
?
webserver:user
660 - 666 / 770 - 777
?

1.1.3.1. Option

For your consideration
find . -type d -exec chmod 755 {} \; ; chmod 755 . ; find . -type f -exec chmod 755 {} \; ; chmod 751 db/local.php

1.1.3.2. Option

The following commands might be useful. In particular, it might help you use an IDE (PhpStorm), etc:

For your consideration
$ export PathToTiki="/var/www/tiki"
$ export WebServerOwner="www-data"
$ sudo usermod -aG ${WebServerOwner} $(whoami)
$ sudo chown -R ${WebServerOwner}: ${PathToTiki}
$ sudo chmod -R g+rw ${PathToTiki}

In English, the above code adds you to the web-server group; forces the tiki tree to be owned by the web-server user and group; and then makes sure the tiki tree is readable and writable by the web-server group (you). Suggestions welcome!
