We can verify in the MySQL server with the following commands: This role supports enabling MySQL slow query log, we can define the location of the log file as well as the slow query time. For example, on the Ansible host, retrieve the public key content: Connect to the target host and paste the Ansible's host public key into ~/.ssh/authorized_keys: You may now try to run a remote command from Ansible host to verify and you should not be prompted with any password. remi,epel). Drupal is a popular CMS whose installation is time-consuming, but easy to automate. The author of this role has created a number of MySQL related variables that can be represented with Ansible role variables. The mysql_replication_user uses the same keys as individual list items in mysql_users, and is created on master servers, and used to replicate on all the slaves. We can then verify if the new configuration options are loaded correctly: Ansible can be used to automate the database deployment and configuration management with a little knowledge of scripting. Ansible Mysql Hardening. Work fast with our official CLI. # ansible-galaxy search For example to search for a role named mysql run. Rollenabhängigkeiten ; Trennen von verteilungsspezifischen Aufgaben und Variablen innerhalb einer Rolle Meanwhile. The default values are tuned for a server where MySQL can consume ~512 MB RAM, so you should consider adjusting them to suit your particular server better. http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm. Voraussetzung für dieses Tutorial ist eine Funktionsfähige Ansible Installation sowie eine ssh Zugriff auf das Zielsystem mit Ansible. To install it use: ansible-galaxy collection install community.mysql. To tell Ansible what to deploy, we need to define the deployment steps in a YML formatted file called playbook. Roles can be dropped into Ansible PlayBooks and immediately put to work. mysql_replication_master needs to resolve to an IP or a hostname which is accessable to the Slaves (this could be a /etc/hosts injection or some other means), otherwise the slaves cannot communicate to the master. mysql_query: runs SQL queries against MySQL. We will start with a simple standalone MySQL deployment, as illustrated in the following high-level diagram: For this walkthrough, we need to have at least two hosts - One host is for Ansible (you could use a workstation instead of a server) and another one is the target host that we want to deploy a MySQL server. mysql_replication: configures and operates asynchronous replication.

Set this to python-mysqldb if using older distributions running Python 2. Create a directory and a simple MySQL configuration file: Let's say we have another configuration file specifically for mysqldump configuration: To import these configuration files into our deployment, define them in the mysql_config_include_files array in vars/main.yml file: Note that /root/custom-config/mysqld-severalnines.cnf and /root/custom-config/mysqldump.cnf exist inside the Ansible host. Next, we define the location of variables file (var_files) located at vars/main.yml, relative to the playbook path. Another technology we’ve been leveraging for automation for MySQL and other database technologies is Ansible. Using the ansible-galaxy command line tool that comes bundled with Ansible, you can create a role with the init command. To run the role on my server, I add the entry gerlingguy.docker to the array roles in the happy1.yml file, which I created in the previous article in the series. community.mysql.mysql_user. Suppose we want to install MySQL from another vendor, we can extend the playbook with pre_tasks, a task which Ansible executes before executing any tasks mentioned in any .yml file, as shown in the following example: The above will install MySQL from Oracle repository instead. ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password='test'; Solution 1: However, Ansible, as of version 2.0.2 didn't account for this. Notes.

Since you're going to need a simple Ansible playbook and inventory file to test your role, you can create both inside a new 'tests' directory in your Ansible role: Inside the inventoryfile, add: We just want to tell Ansible to run commands on the local machine (we'll use the --connection=localoption when running the test playbook). mysql_replication: configures and operates asynchronous replication. Ansible MySQL role – creating databases and users 7 April 2017 / by Author Emil. Let's create the variable directory and file and specify the following line: For more information check out the Role Variables section in the Readme file of this role.

Commit Score: This score is calculated by counting number of weeks with non-zero commits in the last 1 year period. The simplest definition in playbook gives us a very basic installation and uses all default configuration options. mysql_user: creates, modifies and deletes MySQL users. At this point, our passwordless SSH is configured. To secure this user as part of an idempotent playbook, you must create at least two tasks: the first must change the root user’s password, without providing any login_user/login_password details. Firstly, generate a SSH key on the Ansible host: You should get at least the following files generated: To allow passwordless SSH, we need to copy the SSH public key (id_rsa.pub) to the remote host that we want to access. (Ubuntu/Debian only) If you need to explicitly override the MySQL Python package, you can set it here. Each item in the array requires a "src" parameter which is a path to a file. $ cd roles $ ansible-galaxy init server $ ansible-galaxy init php $ ansible-galaxy init mysql $ ansible-galaxy init wordpress This brings in template configurations for individual components from ansible-galaxy which is a repository for many standard ansible configurations. (RedHat/CentOS only) If you have enabled any additional repositories (might I suggest geerlingguy.repo-epel or geerlingguy.repo-remi), those repositories can be listed under this variable (e.g. Slow query log settings. mysqldump reference Set mysql_server_id and mysql_replication_role by server (e.g. A list of files that should override the default global my.cnf.
