I have written a module that is refusing point blank to create the tables within my mysql4-install-1.0.0.php file....but only on the live server.
The funny thing is that on my local machine (which is a mirror of the live server (i.e. identical file structure etc)) the install runs correctly and the table is created.
So based on the fact that the files are the same can I assume that it is a server configuration and or permissions problem? I have looked everywhere and I can find no problems in any of the log files (PHP, MySQL, Apache, Magento).
I can create tables ok in test scripts (using core_read/write).
Anyone see this before?
Thanks
** EDIT ** One main difference between the 2 environments is that on the live server the MySQL is remote (not localhost). The dev server is localhost. Could that cause issues?
Is the module which your install script is a part of installed on the live server? (XML file in app/etc/modules/, Module List Module for debugging.)
Is there already a record in the core_resource table for your module? If so, remove it to set your script to re-run.
If you file named correctly? The _modifyResourceDb method in app/code/core/Mage/Core/Model/Resource/Setup.php is where this file is include/run from. Read more here
Probably a permissions issue - a MySQL account used by public-facing code should have as few permissions as possible that still let it get the job done, which generally does NOT allow for creating/altering/dropping tables.
Take whatever username you're connecting to mysql with, and do:
SELECT User, Host
FROM mysql.user
WHERE User='your username here';
This will show you the user#host combos available for that particular username, then you can get actual permissions with
show grants for username#host;
Do this for the two accounts on the live and devlopment server, which will show you what permissions are missing from the live system.
In the Admin->System->Advanced section is your module present and enabled?
Did you actually unpack your module to the right space, e.g. app/code/local/yourcompany/yourmodule ?
Do you have app/etc/modules/yourmodule.xml - I believe that this could be the overlooked file giving rise to your problem.
the cache could be the culprit, if you manually deleted the core_resource row for your module in order to make the setup sql run again, you have to also flush the cache
probably a difference between dev and production servers is cache settings, that would explain why you only see this in production
For me, the issue appeared using Windows for development. Linux system is case sensitive. In my config.xml the setup section was named camelCase while the folder was named all-lowercase. Making them the same made the script run.

tried to serach in documentation but I have a lot of doubts...
I'm running ejabberd version 2.1.9 on an old debian server (5.0.8) with more than 500 users...
Now I was asked to update to the latest version, but I need some advice;
in the documentation I saw there are specific upgrade instructions between versions also from 2.1.x to 16.02
if I upgrade to 16 version can I jump directly to 22.10 or I have to upgrade to every intermediate releases?
or as an alternative, is possible to export users, passowrds, shared rooster ecc..and restore them on a fresh installed 22.10 ?

Thank you very much for detailed info :-)
but I'm stuck with backup database... If I use the plain text backup "ejabberdctl dump" give me errors importing table "pubsub_node" on the new server

any Suggestion?
with more than 500 users
An ejabberd server with around 500 online users? That's a small server, I guess you don't even use SQL database, so that's one less thing to worry about.
An ejabberd deployment is composed of:
the code (source or binary)
configuration file (or files)
mnesia internal database, that is stored in the mnesia spool dir (see system install)
SQL database (if you configure it)
log files (only useful for your interest and consult)
When upgrading ejabberd code, it is usual that the release notes mention some changes in the configuration, and some changes in SQL schemas. The changes in the mnesia internal database are implemented inside ejabberd and applied automatically when needed.
I have to upgrade to every intermediate releases?
In general no need. In general when jumping a few releases, you just read the release notes and apply the configuration and SQL schema changes of all the intermediate releases.
But in your case... as it's a big jump, I recommend you to not touch the production server yet. First test the upgrade in another machine (your personal machine, or other unused server, or a laptop, or a docker container...), so you learn how to do it perfectly without annoying the users.
There are many ways; but I were you, or if I were sitting in a chair next to you, this is how I would do it. I would be optimistic and try to jump from from 2.1.9 to 22.10, but slowly, and using a temporary server for testing the process and learning:
In a testing machine install the desired ejabberd version (22.10 or whatever). It should work perfectly, as it's empty and has default configuration. Notice most XMPP clients allow you to login to an account whatever#example.com specifying the IP address and port of the server: in your case you will have to specify the IP address of the new ejabberd server, as the XMPP domain it doesn't match the DNS name.
Obviously, the configuration in the new server will lack customizations that are essential for you (the served domain, what accounts are admins, certificate files, port numbers, custom modules...)
Copy the old configuration file to the new server. Notice they use different formats (ejabberd.cfg in erlang format... and ejabberd.yml in YAML format).
Manually and slowly apply one of your customizations in the new configuration file. Restart ejabberd, check it starts and works correctly, and then repeat with another customization.
Now you have a new ejabberd server running, with all (or most) of your desired configuration. Two things are lacking: the users data, and of course replacing the old ejabberd with the new ejabberd.
In the production ejabberd server, export the mnesia database using "ejabberdctl backup" and "ejabberdctl dump" (better to have two alternatives, in case one doesn't work). Copy those files to the machine that has the new ejabberd server.
In the new ejabberd, run restore specifying the binary backup
(or load specifying the text dump). With some luck, this will end correctly.
Restart ejabberd. It will notice that the mnesia tables use very old schemas, and will automatically update them. This may take a while. With some luck it will end correctly.
If steps 7 or 8 fail, and you are lucky to know what username or what data is problematic, you can try to delete or "fix" that in the text dump file before loading it).
Once you are happy with the new ejabberd server (the new configuration looks great, has all your customizations, and all the users are correctly imported), then it's time to replace the old ejabberd with the new one.
Alternatively, you can try to upgrade from 2.1.9 to 16.02, and later from 16.02 to 22.10
In any case, general recommendations:
take it slowly because there are many steps
be patient because you may face small problems that require fixing before continuing to the next step
be kind to yourself because you never did this
annotate every major problem you face, and how you fixed it (in case you find this problem again this day or in the next days, or eventually somebody else in your organization)
be sure this can be done (in the worst case, with a progressive upgrade from one version to the next :)
Back in september '17 I installed an ejabberd-instance on a (debian 9-)server my dad still pays for, but is no longer using. The small circle of friends that initially used it, quickly grew and now there's a few hundred of us chatting away.
Time has come to update the ejabberd (I installed 16.09-4) because we want to stay secure and be able to enjoy all the latest whistles and bells. I thought some simple 'apt-get upgrade'-magic would do the trick, but boy, was I wrong.
I looked at the docs (Specific version upgrade notes) and tried to update to 17.03, by following the steps described there.
These updates fail miserably (missing links to /usr/sbin/ causing failure to to restart server after update. Adding symlinks does not help. I believe I chose to install to /opt/ last year, which would explain why).
Since I have some experience with MySQL and none whatsoever with Mnesia, I also decided in the beginning to add "default_db : SQL" in my ejabberd.yml file. I (wrongly) assumed all data would be stored in a MySQL-DB, and no longer in the Mnesia. This does not seem to be the case: I see all of the registered users in Mnesia (using ejabberdctl) but only part of the complete list in MySQL.
I guess my question is twofold:
What would be the most efficient way to update from 16.09-4 to the latest version ? (I am aiming for a solution without having to install a new ejabberd-instance on a different server and simply backing up and migrating the MySQL)
How can I avoid using Mnesia completely and only use MySQL ? And, related: How can I push all existing Mnesia-data into MySQL ?
What would be the most efficient way to update from 16.09-4 to the latest version ?
As you have some kind of confusion about what and where is installed, problems in links, paths, etc, I propose as "the most efficient" a solution that has many many steps, but at least will work whatever you have:
First handle the old one:
Find your config dir and mnesia spool (try 'ejabberdctl help')
Stop ejabberd
Move to a safe location your config dir and mnesia spool
Uninstall ejabberd and all ejabberd related files and dirs
Now comes the new one:
Install ejabberd in the way you prefer: Debian package, source, whatever
Let it start, so it creates default config files and minimal mnesia spool
You can even register an account, login, check it runs correctly
Find the new config dir and mnesia spool (maybe they are different paths due to different install process)
Stop ejabberd
And now recover your old information
Replace the new config dir with old one, and the new mnesia spool with your old one
Start ejabberd again, with old config and old mnesia. It may complain about useless or unknown options, it may also report it's updating the database schema.
If it at least starts, check you have all the users, and also update the config file in case there were renamed options...
Of course, there are easier and faster ways to update, but your special case requires special steps.
How can I avoid using Mnesia completely and only use MySQL ?
Why exactly do you want to avoid it at all costs? It's required for some stuff in ejabberd, like client sessions, internal routes, commands... Other stuff can be moved to MySQL, like roster, passwd, MUC, vcards...
And, related: How can I push all existing Mnesia-data into MySQL ?
You can configure many modules to use sql instead of mnesia, and then run the export2sql command that produces a *.sql file that you will import into your new MySQL database. After that, you can delete content of mnesia tables using the WebAdmin.
I'm having this issue listed here and I was recently told that it is impossible to resolve this issue -- so I had the idea of running phpMyAdmin on its own user (other than Apache's user). I'm running Ubuntu with Apache, is this possible?
Thanks!
It's not possible because phpMyAdmin is not a process, it's a series of scripts interpreted by a process (either by mod_php running inside Apache or a separate PHP process like php-fpm).
First ever Stack Overflow post, thanks for your time. Any constructive criticism on how to post better, please just let me know. I have done a search on my query and have found similar posts, but I was unable to use the information within them to resolve my problem.
I have created a mysql database using the terminal window in my Ubuntu system (which I am also new to, having been a lifelong windows user). I used the following code in the terminal window:
$ mysql -u root -p
Then once in mysql, I did the following
CREATE DATABASE securities_master;
USE securities_master;
I created a user and tables in the database using some other code, that doesn't seem relevant here, so I won't bother posting. However, I then decided I would like to take a look at the tables in the database, so I downloaded an SQLite browser. It was at this point that I realized I could not find my database file.
I tried to find the answer on previous stack overflow posts, and tried the suggestions of:
locate sqlite
locate .db
locate .sqlite
locate securities_master
But unfortunately, none of these showed the file I was looking for. The only place I can think of would be what is called the 'root' directory in my computer, but the Ubuntu file manager system won't let me view it because it says I don't have permissions. Is this where it might be?
Could someone shed some light on where I might be able to find this file/database? I know it is definitely there because if I try to CREATE it again, I get the message that it can't because it already exists.
Thanks again.
sqlite and mysql are two different databases. You can't use sqlite on a mysql database. sqlite is a single-file database, in which users just open the file and read and write to it, while mysql is a more traditional relational database system with a server and a client, where the server manages the database (which is generally in a directory of files), while the client just connects to the server.
Where the mysql database is located my depend on your system, but it's usually in /var/lib/mysql. You can look in /etc/mysql/my.cnf for the configuration file, which should have a datadir option that refers to where the actual data for the database is stored.
You can check my.ini file to see where the data folder is located.
Usually there is a folder {mysqlDirectory}/data
MySQL data storage:
Commands.frm
Commands.myd
Commands.myi
The *.frm files contain the table definitions. Your *.myi files are MyISAM index files. Your *.myd files contain the table data.
as mentioned in the answer before mine, mysql and sqlite are two different systems.
You mention you used the cmd line mysql to create the database and then wanted to view the tables. If you're simply trying to see which table are created, in the same command line you used to Create the database you can run show tables;
If you're after a GUI for this, we'd need a bit more context. Is this ubuntu system a remote server, or are you using the desktop version?
You say you're a long time windows user, If you're using windows locally, I personally like SQLWorkbench for accessing my remote mysql servers.
EDIT: I just re-read your post and realised you're using local ubuntu desktop so me mentioning remote was silly, my bad! However, SQLWorkbench does have a ubuntu version at https://dev.mysql.com/downloads/workbench/
I'm trying to migrate a web site to friend's server. The site uses MySQL, but he didn't previously have it set up. He's installed the package now and suggested that I could run my own instance of it. I'm at a loss for how to do so. Is it even possible? If so, how?
Some relevant information:
The OS in use is CentOS 5.9
Using MySQL 5.0.95
I only need the DB to be read locally via PHP when serving my site.
I have no root privileges on this system (although a full shell), but am close friends with the owner/administrator if that's necessary.
To clarify:
It's the daemon that I want to run my own instance of. So I guess what I want to know is if it's possible to have multiple users on the system running their own instances of mysqld containing different databases.
All I need this for is serving a web page. If I have to break down and switch to a pseudo-database using CSV files I will, but I'd much rather stick to MySQL if I can.
If MYSQL is setup on that machine yes you can run your own instance of it.
You can have it set up and your site given its on Database within that MYSQL instance and that specific MYSQL account can be used to access the tables etc. involved with your website.
Now if he is only putting MYSQL on the machine then having you set everything up you will just need an account for MYSQL and from ther eyou can get in and just create all the needed items that will allow your site to fully function.
EDIT
In response to your comment. You can you just can't clog the same port or have configurations that conflict each other. As long as it won't be to much of a performance hit and you configure a different user to start each instance you should be able to do Something like this.
