I'm installing ruby from source and using template to export path. My code looks like this:
- name: clone rbenv
git: repo=git://github.com/sstephenson/rbenv.git dest=/usr/local/rbenv
become: yes
- template: src=templates/rbenv.sh.j2 dest=/etc/profile.d/rbenv.sh
become: true
- name: clone ruby-build repo
git: repo=git://github.com/sstephenson/ruby-build.git dest=~/ruby-build
- name: Install ruby-build
shell: ./ruby-build/install.sh
become: yes
- name: install jruby
shell: . /etc/profile.d/rbenv.sh && rbenv install jruby-9.0.5.0
become: yes
I want to use command "rbenv",
this works but in this way I have to source profile with every command.
Is there any way to source profile once in ansible.config file or something else and use it in the whole project without sourcing profile again.
Either add path in .bashrc
or
- name: install jruby
shell: . /etc/profile.d/rbenv.sh && rbenv install jruby-9.0.5.0
become: yes
args:
executable: /bin/bash -l
/bin/bash -l behaves as login shell

I'm looking for a way to install a given version of node via ansible and nvm, the installation of nvm is working as expected because if I connect with the root user, I can execute the command nvm install 8.11.3 but this same command doesn't work with Ansible, I don't understand why.

It's okay, here's the configuration that works
- name: Install node and set version
become: yes
become_user: root
shell: "source /root/.nvm/nvm.sh && nvm install 8.11.3"
args:
executable: /bin/bash
I think the clue in the output you need is:
"/bin/sh: 1: nvm: not found"
To run a command without including the full path to that command (i.e. nvm rather than /the/dir/nvm/is/installed/in/nvm), then the directory that contains the command, must be in the $PATH environment variable for the shell that runs the command.
In this case it looks like that is not present for the shell that Ansible spawns, versus the shell your interactive commands run in. Change:
- name: Install node and set version
become: yes
become_user: root
shell: nvm install 8.11.3
to
- name: Install node and set version
become: yes
become_user: root
shell: /full/path/to/nvm install 8.11.3
If you don't know what to put in place of '/full/path/to', try either:
which nvm
or
find / -name nvm
I will just post under here, because there are hundreds of these posts.
- name: Install node
become: true
become_user: root
shell: "source /root/.nvm/nvm.sh && nvm install {{ personal_node_version }} && nvm alias default {{ personal_node_version }}"
args:
executable: /bin/bash
worked for me.
This worked for me on Ubuntu 20.04 using nvm version 0.39.1:
- name: Install NVM
shell: >
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
args:
creates: "/root/.nvm/nvm.sh"
- name: Install Node Versions
shell: ". /root/.bashrc && nvm install {{item}}"
with_items:
- 'v10.24.1'
- 'v16.17.0'
- '--lts'
- 'node'
Based on all the posts found on stack and tweaked a little for my own needs - I found this solution worked perfectly for both installing NVM (the easy part) and creating a loop that allows you to insert 1 or many versions of Node as needed
# test if nvm has been installed by the user desired
- stat:
path: /home/yournonrootuser/.nvm
register: nvm_path

I am working on Ansible playbook to execute some of my tasks. In one of my tasks, I need to switch to particular directory and then execute a command using sudo but I need to do all these things by switching to root user first otherwise it won't work. So in general this is what I do without ansible:
david#machineA:/tmp/parallel-20140422$ sudo su
root#machineA:/tmp/parallel-20140422# sudo ./configure && make && make install
After above steps, I see GNU parallel library is installed in my system correctly. But with the below steps using Ansible, I don't see my GNU library getting installed at all.
- name: install gnu parallel
command: chdir=/tmp/parallel-20140422 sudo ./configure && make && make install
Now my question is how can I switch to root user and execute a particular command. I am running Ansible 1.5.4 and looks like I cannot upgrade. I even tried with below but still it doesn't work:
- name: install gnu parallel
command: chdir=/tmp/parallel-20140422 sudo ./configure && make && make install
sudo: true
sudo_user: root
I am running my playbook using below command:
ansible-playbook -e 'host_key_checking=False' setup.yml -u david --ask-pass --sudo -U root --ask-sudo-pass
You need the become directive.
For example, to start a service as root:
- name: Ensure the httpd service is running
service:
name: httpd
state: started
become: true
you can also become another user, such as the apache user:
- name: Run a command as the apache user
command: somecommand
become: true
become_user: apache
For your case, it will be:
- name: install gnu parallel
command: chdir=/tmp/parallel-20140422 sudo ./configure && make && make install
become: true
From your comment:
I know command module is working fine bcoz I verified for other tasks and they work fine.
command module might be working for other commands, but in this example you use a shell syntax (&&) to execute multiple commands. This syntax will not work in the command module (because this module runs commands directly from Python and does not support combined commands).
You need to use the shell module in this case.
- name: install gnu parallel
shell: ./configure && make && make install
args:
chdir=/tmp/parallel-20140422
sudo: true
sudo_user: root
I am using the apt-get install the pure-ftp on ubuntu server 14.04.4
sudo apt-get install pure-ftpd
sudo pure-uploadscript -B -r /home/john/hello.sh
the hell.sh file, and it's able to run.
#!/bin/sh
echo "hello"
Then, I use FileZilla to upload the file. I can upload the file, but the script is not called. please help;
official doc
If you install the pure-ftpd server by apt-get, it may not give you the feature that you want to use. I checked the /var/run folder, some file are missing there. I complied the code with --with-uploadscript, it's working now.
I had to also compile from source, fortunately the install is not too heavy. It may be worth uploading the compiled files from your system to your mirror and just downloading and running make install. On the other hand, this works as well:
- name: install pure-ftpd from source
block:
- name: create required pure-ftpd dirs

path: /etc/pure-ftpd

I want to install python3.x by use pyenv with ansible.
- name: install pyenv
git: >
repo=https://github.com/pyenv/pyenv.git
dest=/home/www/.pyenv
accept_hostkey=yes
become: yes
become_user: www
- name: enable pyenv
shell: |
echo 'export PYENV_ROOT="/home/www/.pyenv"' >> /home/www/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> /home/www/.bashrc
echo 'eval "$(pyenv init -)"' >> /home/www/.bashrc
- name: install python
shell: pyenv install 3.4.3
How to install python3.x with ansible?
So here is what worked for me well to get any version of python installed with ansible and make it an alternative installation. I first ran configure and make, later compressed the result since this takes a while, then re-distributed the file using a mirror so I can run make altinstall on its own. Here is the recipe:
---
# Check the alt python3 version
- name: check alt python version
shell: /usr/local/bin/python3.6 --version
register: python3_version
ignore_errors: yes # If not installed
tags:
- python-alt
# Stuff I did manually to compile everything first by hand
# Python3 alt-install - steps to create binary:
# wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz
# tar xf Python-3.6.4.tgz
# mv Python-3.6.4 Python-3.6.4-binary && cd Python-3.6.4-binary
# ./configure --prefix=/usr/local --enable-optimizations
# cd .. && tar -zcvf Python-3.6.4-binary.tar.gz Python-3.6.4-binary (upload to mirror servers)
# make && sudo make altinstall UNINST=1
- name: download and unpack alternative python3
unarchive:
src: http://www.yourmirror.com/centos/python/Python-3.6.4-binary.tar.gz dest=/tmp/Python-3.6.4-binary.tar.gz
dest: /tmp
remote_src: yes
keep_newer: yes
when: python3_version['stderr'] != 'Python 3.6.4'
tags:
- python-alt
# Its possible to install (instead of altinstall) python3 here
- name: make install alt python3
make:
chdir: /tmp/Python-3.6.4-binary
target: altinstall
params:
UNINST: 1 # Replace
when: python3_version['stderr'] != 'Python 3.6.4'
become: yes
tags:
- python-alt
- name: download get-pip.py
get_url:
url: https://bootstrap.pypa.io/get-pip.py
dest: /tmp/get-pip.py
mode: 0664
tags:
- python-alt
- name: install pip for python3
shell: /usr/local/bin/python3.6 /tmp/get-pip.py
become: yes
tags:
- python-alt
# We need virtualenv installed under py3 for the virtualenv command to work
- pip:
name: virtualenv
executable: /usr/local/bin/pip3.6
become: True
tags:
- python-alt
If you want to compile everything on your server you could do the following before the altinstall step and also download the source code package instead of the pre-compiled tar. I don't recommend doing it this way because it does take up resources and you don't want to be doing it in prod. Using Python2.7.14 as an example:
---
# Build the default target
- debug:
var: python2_version
tags:
- python_alt
- make:
chdir: /tmp/Python-2.7.14-binary
when: python2_version['stderr'] != 'Python 2.7.14'
tags:
- python_alt
- name: configure target command
command: ./configure --prefix=/usr/local --enable-optimizations chdir=/tmp/Python-2.7.14-binary
when: python2_version['stderr'] != alt_python_version
tags:
- python_alt
Rather than using the shell module to set environment variables on the remote host, Ansible has the environment keyword, which can set per task or even per playbook.
Assuming the www user already exists I managed to get this working with some more specific path setting:
- name: enable pyenv and install python
shell: /home/www/.pyenv/bin/pyenv init - && /home/www/.pyenv/bin/pyenv install 3.4.3 chdir=/home/www
environment:
pyenv_root: /home/www/.pyenv
path: "{{ pyenv_root }}/bin:$PATH"
become: yes
become_user: www
You will need to run the playbook with:
ansible-playbook --ask-become-pass <playbook-name>
and supply the password for the www user on request.
If that doesn't work, you might have to post the whole playbook here for us to look at :)
I haven't used Ansible before, does anyone know how to write a simple playbook that uninstalls nano and installs vim on a Linux server? I would imagine you would need to include an option to configure which text editor preference you want after doing the above.
Cheers
edit
This is what I've got so far...
---
# Playbook to uninstall nano and install vim
- hosts: all
remote_user: luca
sudo: yes
tasks:
- name: uninstall nano
action: command: sudo apt-get purge nano
- name: Install vim
action: command: sudo apt-get install vim
tmp.yml
---
- hosts: all
tasks:
- name: nano remove
apt: name=nano state=absent
- name: vim install
apt: name=vim state=present
ansible-playbook tmp.yml
http://docs.ansible.com/apt_module.html
If you are working on fedora/centos/rhel:
---
- hosts: all
tasks:
- name: nano remove
yum: name=nano state=absent
- name: vim install
yum: name=vim state=latest
Refer to doc of yum module . Set proper args for "state": install (present or installed, latest), or remove (absent or removed) a package.
If you want to remove and install with command, you must write without 'action', like this:
tasks:
- name: uninstall nano
command: sudo apt-get purge nano
- name: Install vim
command: sudo apt-get install vim
But it is not recommended, it is better doing with 'absent'.
And I am not sure if can put sudo, so you can connect directly with your root user.
- hosts: all
remote_user: root
sudo: True
I personally find it cleaner with a loop for the installs. For the uninstall just change the "state"
hosts: desktop-linux
tasks:
- name: Install Desktop packages
apt: name={{item}} state=installed
with_items:
- meld
- synergy
- retext
- pidgin
- steam
- ubuntu-restricted-extras
- nautilus-admin
- unity-tweak-tool
- vlc
