i'm trying to install Docker-compose on my Raspberry Pi 3+ which installed Raspbian buster.
I followed instruction on docker.com. After I entered command : sudo curl -L https://github.com/docker/compose/releases/download/1.20.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose.
It show a table for downloading
Result
It seems nothing downloaded, just have a file docker-compose saved in /usr/local/bin/docker-compose. When I opened it, it empty. Then I enter command docker-compose -v, it displayed error /usr/local/bin/docker-compose : line 1: Not: command not found.
Anyone have solution?
UPDATE:
Added the following command to my answer to download the LATEST version without specifying any version number at all so the download can be scripted.
curl -L "https://github.com/docker/compose/releases/download/$(curl https://github.com/docker/compose/releases | grep -m1 '<a href="/docker/compose/releases/download/' | grep -o 'v[0-9:].[0-9].[0-9]')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
It's a bit untidy, but it works. If you have a more elegant way than mine, ping it to me in the comments and I'll update my answer.
Just need to set the perms on the file:
chmod +x /usr/local/bin/docker-compose
Use the file command to validate that you pulled the correct arch for your system.
Intro:
Although docker-compose can be installed from a repo per the accepted answer, apt-cache show docker-compose reveals that as of 20211201 the repo version is only v1.25; about 2 years behind the current v2.1.1 release. In order to take advantage of more modern docker file versions, I needed to get the Github download working.
Short Answer:
The Docker documentation for Docker-Compose is WRONG. They forgot to preface the version number in the command with a "v"; consequently the download fails. Apparently this has been wrong for ages...
Longer Answer:
I ran the below command from the Docker-Compose documentation, and substituted the version "2.1.1" for "1.29.1" per Docker's guidance:
To install a different version of Compose, substitute 1.29.2 with the
version of Compose you want to use.
sudo curl -L "https://github.com/docker/compose/releases/download/2.1.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
The resulting download was 9 KB for a 23 MB binary. Clearly the link was bogus. So I went to the root of the address used in the command "https://github.com/docker/compose/releases" and right-clicked on the version of Docker-Compose that I wanted and chose "Copy Link Address"
This revealed the link Docker was telling folks to use didn't have a "v" prefaced before the version number in the https:// address part of the command.
Solution:
Preface a "v" before the version number you want in the link as below and the command executes successfully:
sudo curl -L "https://github.com/docker/compose/releases/download/v2.1.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
BTW, I too was downloading docker-compose for a Raspberry Pi using the aarch64 binary for Ubuntu 20.04 LTS. However, the missing "v" fix for the broken download address should work for any platform.
This is because on a raspberry pi the url part of the command results in
https://github.com/docker/compose/releases/download/1.24.1/docker-compose-Linux-armv7l
Looking at the latest stable release at https://github.com/docker/compose/releases/tag/1.24.1 you can see there is no download for the armv7l architecture so the file is empty because there is nothing to download.
Will update answer once I figured out how to install docker-compose on Raspian.
Edit:
Via apt-get. Note: Currently (Nov. 8 2019) this installs version 1.21 which is not the latest available.
sudo apt-get install docker-compose
Via pip3. (Installs latest)
sudo apt-get install python3-pip
sudo pip3 install docker-compose
And then restart your system with
sudo shutdown -r
I am trying to install the matlab on my ubuntu 14.04. I have downloaded the student trial version from mathworks. I downloaded a zip file. The other resources are telling me to unzip it and the open the installer. I did that but I cannot find the installer. if i click on install it opens some text file which has some shell programming in it
Please help me to get out of this problem.
You will need to use ISO images:
Assuming that image is named R2015b_glnxa64.iso, simply mount ISO:
sudo mkdir -p /media/iso sudo mount -o ro,loop ./R2015b_glnxa64.iso
/media/iso
run the installation script:
sudo /media/iso/install
and if you want to install (two DVDs/ISOs), you should use the same path for mounting both ISO images:
1.
mount DVD1 sudo mount -o ro,loop /media/data/R2017a_glnxa64_dvd1.iso /media/iso,
2.
install sudo /media/iso/install and wait for a pop-up window to change the disk,
3.
mount DVD2 sudo mount -o ro,loop /media/data/R2017a_glnxa64_dvd2.iso /media/iso
and finally unmount image:
You can just install matlab with this one line command.
sudo apt-get install matlab-gdf dynare-matlab libpdl-io-matlab-perl matlab-support matlab-support-dev matlab2tikz
I went through fair amount of google search to install ack-grep on CentOS but I didn't find anything help. I also looked for the source codes but couldn't find it neither. Does anyone know how to install it on the OS?
Thanks a lot.
Could be essentially the same as https://stackoverflow.com/a/23155007/35946 but on CentOS 6.7 the answer is:
# yum install epel-release
# yum install ack
if you don't have the root permission, you can do as follows:
$ curl https://beyondgrep.com/ack-2.22-single-file > ~/bin/ack && chmod 0755 !#:3
or you can change to root user:
$ sudo su
# curl https://beyondgrep.com/ack-2.22-single-file > /bin/ack && chmod 0755 !#:3
You can get it from the EPEL software repository.
From the EPEL FAQ:
For EL5:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
...
su -c 'yum install ack'
For EL6:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'
...
su -c 'yum install ack'
Go to Beyond Grep and look at the section titled
Install The ack executeable
curl http://beyondgrep.com/ack-2.14-single-file > ~/bin/ack && chmod 0755 !#:3
And replace ack.2.14 with the current version of ack.
You may need to create the directory mkdir ~/bin/ first. You may
also need to modify ~/.bashrc to include this new path E.G.:
PATH=$PATH:$HOME/bin
Then reload ~/.bashrc
source ~/.bashrc
Test the installation by running ack:
rpm -qa | ack s
This should display any installed packages containing the letter s. (some linux distributions may use ack-grep as the command.
How did you try installing it? Are you using yum? The package is probably not called "ack-grep", but just "ack".
The name "ack-grep" is a Debian-specific thing because there was already a package called "ack", so they called it "ack-grep" instead. That was years ago and now they're dropping the original "ack" package and renaming "ack-grep" to "ack".
For RedHat Enterprise just do sudo yum install ack
I am trying to dump a Postgresql database using the pg_dump tool.
$ pg_dump books > books.out
How ever i am getting this error.
pg_dump: server version: 9.2.1; pg_dump version: 9.1.6
pg_dump: aborting because of server version mismatch
The --ignore-version option is now deprecated and really would not be a a solution to my issue even if it had worked.
How can I upgrade pg_dump to resolve this issue?
Check the installed version(s) of pg_dump:
find / -name pg_dump -type f 2>/dev/null
My output was:
/usr/pgsql-9.3/bin/pg_dump
/usr/bin/pg_dump
There are two versions installed. To update pg_dump with the newer version:
sudo ln -s /usr/pgsql-9.3/bin/pg_dump /usr/bin/pg_dump --force
This will create the symlink to the newer version.
I encountered this while using Heroku on Ubuntu, and here's how I fixed it:
Add the PostgreSQL apt repository as described at "Linux downloads (Ubuntu)
". (There are similar pages for other operating systems.)
Upgrade to the latest version (9.3 for me) with:
sudo apt-get install postgresql
Recreate the symbolic link in /usr/bin with:
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_dump /usr/bin/pg_dump --force
The version number in the /usr/lib/postgresql/... path above should match the server version number in the error you received. So if your error says, pg_dump: server version: 9.9, then link to /usr/lib/postgresql/9.9/....
Macs have a builtin /usr/bin/pg_dump command that is used as default.
With the postgresql install you get another binary at /Library/PostgreSQL/<version>/bin/pg_dump
You can just locate pg_dump and use the full path in command
locate pg_dump
/usr/bin/pg_dump
/usr/bin/pg_dumpall
/usr/lib/postgresql/9.3/bin/pg_dump
/usr/lib/postgresql/9.3/bin/pg_dumpall
/usr/lib/postgresql/9.6/bin/pg_dump
/usr/lib/postgresql/9.6/bin/pg_dumpall
Now just use the path of the desired version in the command
/usr/lib/postgresql/9.6/bin/pg_dump books > books.out
You can either install PostgreSQL 9.2.1 in the pg_dump client machine or just copy the $PGHOME from the PostgreSQL server machine to the client machine. Note that there is no need to initdb a new cluster in the client machine.
After you have finished installing the 9.2.1 software, remember to edit some environment variables in your .bash_profile file.
If you're on Ubuntu, you might have an old version of postgresql-client installed. Based on the versions in your error message, the solution would be the following:
sudo apt-get remove postgresql-client-9.1
sudo apt-get install postgresql-client-9.2
If you have docker installed you can do something like:
$ docker run postgres:9.2 pg_dump books > books.out
That will download the Docker container with Postgres 9.2 in it, run pg_dump inside of the container, and write the output.
On Ubuntu you can simply add the most recent Apt repository and then run:
sudo apt-get install postgresql-client-11
Every time you upgrade or re install a new version of PostgreSQL, a latest version of pg_dump is installed.
There must be a PostgreSQL/bin directory somewhere on your system, under the latest version of PostgreSQL that you've installed ( 9.2.1 is latest) and try running the
pg_dump from in there.
For those running Postgres.app:
Add the following code to your .bash_profile:
export PATH=/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH
Restart terminal.
For Macs with Homebrew. I had this problem when fetching the db from Heroku. I've fixed it just running:
brew upgrade postgresql
For mac users
put to the top of .profile file.
export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
then run
. ~/.profile
An alternative answer that I don't think anyone else has covered.
If you have multiple PG clusters installed (as I do), then you can view those using pg_lsclusters.
You should be able to see the version and cluster from the list displayed.
From there, you can then do this:
pg_dump --cluster=9.6/main books > books.out
Obviously, replace the version and cluster name with the appropriate one for your circumstances from what is returned by pg_lsclusters separating the version and cluster with a /. This targets the specific cluster you wish to run against.
For me the issue was updating psql apt-get wasn't resolving newer versions, even after update. The following worked.
Ubuntu
Start with the import of the GPG key for PostgreSQL packages.
sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
Now add the repository to your system.
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
Install PostgreSQL on Ubuntu
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib
https://www.postgresql.org/download/linux/ubuntu/
As explained, this is because your postgresql is in old version -> update it
For Mac via homebrew:
brew tap petere/postgresql,
brew install <formula> (eg: brew install petere/postgresql/postgresql-9.6)
Remove old postgre:
brew unlink postgresql
brew link -f postgresql-9.6
If any error happen, don't forget to read and follow brew instruction in each step.
Check this out for more: https://github.com/petere/homebrew-postgresql
The answer sounds silly but if you get the above error and wanna run the pg_dump for earlier version go to bin directory of postgres and type
./pg_dump servername > out.sql ./ ignores the root and looks for pg_dump in current directory
I had same error and this is how I solved it in my case.
This means your postgresql version is 9.2.1 but you have started postgresql service of 9.1.6.
If you run psql postgres you will see:
psql (9.2.1, server 9.1.6)
What I did to solve this problem is:
brew services stop postgresql#9.1.6
brew services restart postgresql#9.2.1
Now run psql postgres and you should have: psql (9.2.1)
You can also run brew services list to see the status of your postgres.
This worked for me, a collection of solutions from above and other sites. If you specified a version like postgressql-client-11 before then you need to remove that version first.
sudo apt-get remove -y postgresql-client
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install -y postgresql-client-12
I was facing the same issue. I used docker instead of upgrading pg_dump.
run following command to create a Docker container of postgres 14.2, or any other version as you like.
sudo docker run --name mac_postgres -p 5444:5432 -e POSTGRES_PASSWORD=password -d postgres:14.2
Then take dump using following command. Note: you should change the host, port, username and password according to your actual database credentials.
sudo docker exec -it mac_postgres pg_dump --host=xxxxx0.b.db.ondigitalocean.com --port=250xx --username=doadmin --dbname=test --password > out.sql
After entering password. Your dump will be ready in out.sql file. Then you can delete the docker-container.
sudo docker stop mac_postgres
sudo docker rm mac_postgres
If you're using Heroku's Postgres.app the pg_dump (along with all the other binaries) is in /Applications/Postgres.app/Contents/MacOS/bin/
so in that case it's
ln -s /Applications/Postgres.app/Contents/MacOS/bin/pg_dump /usr/local/bin/pg_dump
or
ln -s /Applications/Postgres.app/Contents/MacOS/bin/* /usr/local/bin/.
to just grab them all
** after install postgres version is match(9.2)
Create a symbolic link or new shortcut
**- on '/usr/bin'
syntag is = sudo ln -s [path for use] [new shortcut name]
example
sudo ln -s /usr/lib/postgresql/9.2/bin/pg_dump new_pg_dump
-- how to call : new_pg_dump -h 192.168.9.88 -U postgres database
Try that:
export PATH=/usr/local/bin:$PATH
If the database is installed on a different machine it has probably correct version of pg_dump installed. This means that you can execute pg_dump command remotely with SSH:
ssh username#dbserver pg_dump books > books.out
You can also use public key authentication for passwordless execution. Steps to achieve that:
Generate (if not yet done) a pair of keys with ssh-keygen command.
Copy the public key to the database server, usually ~/.ssh/authorized_keys.
Test if the connection works with ssh command.
Well, I had the same issue as I have two postgress versions installed.
Just use the proper pg_dump and you don't need to change anything, in your case:
$> /usr/lib/postgresql/9.2/bin/pg_dump books > books.out
For macs, use find / -name pg_dump -type f 2>/dev/null find the location of pg_dump
For me, I have following results:
Applications/Postgres.app/Contents/Versions/9.5/bin/pg_dump
/usr/local/Cellar/postgresql/9.4.5_2/bin/pg_dump
If you don't want to use sudo ln -s new_pg_dump old_pg_dump --force, just use:
Applications/Postgres.app/Contents/Versions/9.5/bin/pg_dump to replace with pg_dump in your terminal
For example:
Applications/Postgres.app/Contents/Versions/9.5/bin/pg_dump books > books.out
It works for me!
On my scenario the production version was 12, and my development version was 11, upgrading the package postgresql-client-xx was enough to solve my incident.
Reference web page : https://www.postgresql.org/download/linux/ubuntu/
sudo apt-get update && sudo apt-get -y upgrade postgresql-client
One interest thing to point out is that after the upgrade the previous version kept installed :
mlazo#mlazo-pc:~$ dpkg -l |grep -i postgresql-client
ii postgresql-client-11 11.8-1.pgdg18.04+1 amd64 front-end programs for PostgreSQL 11
ii postgresql-client-12 12.4-1.pgdg18.04+1 amd64 front-end programs for PostgreSQL 12
Hope my experience would be helpful to someone.
Greetings,
I had the same message, for me it was that I had to adjust the following:
export LD_LIBRARY_PATH=/usr/pgsql-12/lib:....
export LD_RUN_PATH=/usr/pgsql-12/lib:.....
First step: see if postgres has a repository with prebuilt binaries for the version you want for your OS: https://www.postgresql.org/download/
If that doesn't work (for instance if your distro is there but is no longer supported, so correct binaries aren't provided for it), or if you just want to go straight or the source and not have to worry about adding remote repo's, etc.
What I did is download the raw source of postgres for the desired version.
Untar it, cd into it, build it ./configure && make, then:
postgresql-12.3 $ find . -name pg_dump
./src/bin/pg_dump/pg_dump
$ ./src/bin/pg_dump/pg_dump
unable to load libpg.so.5 # if it says this...
$ find . -name libpg.so.5
$ export LD_LIBRARY_PATH=/your/path/to/the/shared/dir/of/above/file
$ ./src/bin/pg_dump/pg_dump # works now
Now you have access to any version that builds on your box. Which should be any.
Full steps tutorial
Your local version needs to match the one used by AWS on the remote server.
Unfortunately, apt-get install will lag behind the official release.
So you need to proceed the following way:
sudo apt-get remove postgresql
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
Then check your error message should be something like
pg_dump: server version: 12.3; pg_dump version: 10.16 (Ubuntu 10.16-0ubuntu0.18.04.1)
So it means you want version 12 (and not 13), for the install of the matching version by specifying the version number (without minor) during your fresh install:
sudo apt-get -y install postgresql-12
Now it works:
pg_dump -h {{endpoint}} -U {{username}} -f dump.sql {{tablename}}
NB: You get the endpoint in Connectivity & security go to https://us-east-2.console.aws.amazon.com/rds/home?region=us-east-2 and click on your DB instance
For Ubuntu 20.04 with the "official" postgresql repo, moving from pg12 to pg13, I had to do this:
sudo apt purge postgresql-12
This was very hard for me to pinpoint. I had played with a variety of these packages:
postgresql-client
postgresql-client-common
postgresql-##
postgresql-client-##
postgresql-server-dev-##
pgadmin
