Initial installation

Concerns

  • Media Wiki 1.6.6
  • Mysql 4.0.15
  • SuSE 9.0 on vserver

Patches

There are some major problems concerning the installation of media wiki on SuSE 9.0 on a vserver:

  1. Mysql is only version 4.0.15
  2. PHP is per default limited in memory

You will get an error during installation.

Because of a bug in php you should do 3 things:

1. php.ini

First edit /etc/php.ini an change the memory limit from 8 to 50MB:

memory_limit = 50M      ; Maximum amount of memory a script may consume (8MB)

2. tables.sql

Second due to a bug in older mysql versions you have to change two installation files of the media wiki.

At the end of the file

/srv/www/PathToMediaWiki/maintenance/mysql5/tables.sql

Change

KEY (job_cmd, job_namespace, job_title)
) TYPE=InnoDB, DEFAULT CHARSET=utf8;

to

KEY (job_cmd(255), job_namespace, job_title(255))
) TYPE=InnoDB, DEFAULT CHARSET=utf8;

3. patch-job.sql

(!) The same (!) like for tables.sql you have to do in file maintenance/archives/patch-job.sql

Database related

Alter user groups in the database

Also see the MediaWiki Manual pages: User_rights

Edit your mysql database:

mysql -u root -p
mysql> use YourMediawikiDBName

Show the actual user settings:

mysql> select user_id,user_name from user;
+---------+-----------+
| user_id | user_name |
+---------+-----------+
|       1 | aUsername |
|       2 | WikiSysOp |
+---------+-----------+
2 rows in set (0.00 sec)

Show the actual usergoups assigned to what users:

mysql> select * from user_groups;
+---------+------------+
| ug_user | ug_group   |
+---------+------------+
|       1 | bureaucrat |
|       1 | sysop      |
|       2 | sysop      |
+---------+------------+
3 rows in set (0.00 sec)

Delete a row:

mysql> DELETE from  user_groups where  ug_group='aGroup' and ug_user='####';

Assign a user to a group:

mysql> INSERT INTO user_groups (ug_user, ug_group) VALUES ('####', 'aGroup');

... where '####' is the user_id of the appropriate user.

Localsettings.php
