Problems installing TANGO on Ubuntu 14.04

The following issue started as an email exchange :

Dear Andy.

Thanks for tube link. I watched the video 3 or 4 times.

After many-many times trying to install Tango, last night it successfully running. But, when I restart my computer, same error of the db server occur and occur again. last installation of the Tango was on fresh Ubuntu 14.04 LTS.
trying to solve with:

export TANGO_HOST=rifai-System-Product-Name:10000

the error remains. Do you have any solver for this problem?.

with best regards,
Rifai

Dear Rifai,

how are you installing TANGO? Do you use the Ubuntu packages to do this? Have you checked out this video (French with English sub-titles):

https://youtu.be/f903EIbiv6w

It is very simple using the Ubuntu packaging system. If you have a question you can always post to the forum or mailing list.

Kind regards

Andy

Dear Rifai,

Welcome in the community!
I asked you some details because your email yahoo.com doesn't give any indication on your affiliation and we worry about false requests.
The problem you described may be due to the TANGO_HOST environment variable or the database server. Have you started the database server on your PC, on which port?
Have you set the TANGO_HOST environment variable to your_database_hostname:10000

Cheers
Jean-Michel

Dear RIfai,

the problem could be due to a number of reasons e.g. network setup, mysql installation, tango installation.

In order to understand we need to know what you have done and what the error is. Could you please check the following:

(1) Have you installed the tango packages as described in the instructions here:

http://www.tango-controls.org/downloads/binary/

(2) Have you installed mysql-server? Can you run mysql tango? What password has been configured?

(3) Check the user+password in /var/lib/tango/.my.cnf are the same as the one you have configured for mysql (you need to be root to do this)

(4) What is in /etc/tangorc

(5) What is your network configuration? You can check by running ifconfig

Send us your results so we can help you solve this problem.

Kind regards

Andy
Dear Andy,

Last installation was follow instruction on tube link. it perfect work just after installation.

following is the result when running your suggestion:

# if it is omitted.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# changes in this file to the variable values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>

# Make the slave read-only. Only users with the SUPER privilege and the

# the slave instead of the master

#*** MyISAM Specific options

# MyISAM uses special tree-like cache to make bulk inserts (that is,

# INFILE) faster. This variable limits the size of the cache tree in
# bytes per thread. Setting it to 0 will disable this optimisation. Do
# not set it larger than "key_buffer_size" for optimal performance.

# large tables to use the slower key cache method to create the index.
#myisam_max_extra_sort_file_size = 10G

Hi

We are facing problems while installing tango on the Ubuntu 14.04 (i.e. Ubuntu trusty).
We have followed the steps mentioned in the video on given link(https://youtu.be/f903EIbiv6w).

We are facing some dependency problems during installation,
In the end of installation it says,
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libtango8-dev : Depends: libcos4-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

We tried to fix the broken dependency with 'sudo apt-get -f install' ,but it shows everything clean.
:~$ sudo apt-get -f install
Reading package lists… Done
Building dependency tree
Reading state information… Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

We also tried to install libcos4-dev manually (sudo apt-get install libcos4-dev). But it also gives the another dependency problem.

Please guide us to resolve these issues.

Thanks & Regards

Strange. I did not have any issues on my recent installs on Ubuntu 15.04. I will try to find a 14.04 version to see if I can reproduce your problem. What hardware platform are you running on - Intel / ARM ?

Andy
Hi, I did not either have any issue of this kind during installation and following steps given in the video.
I will make some tests to check. Perhaps this could be linked to some choices before installation, or apt-get update ?
- Philippe
Can you do the following:

apt-cache policy libtango8-dev
apt-cache show libtango8-dev
