This article mainly introduces what the common methods of ansible have related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will have some gains after reading this article on common methods of ansible, let's take a look at it.

1. Ansible has many modules and many ways to write playbook, but I personally feel that there is no need to be so troublesome. As long as I master the following modules, it will be enough.

First, take a look at the common host list configuration:

[wangsn@m-ubonex-jenkins] $ansible-I / etc/ansible/hosts twm-m shell-a "ls-l / opt"-- sudo-k

Parameter description:

-I: specify the location of the host manifest file

-m: specify the name of the module. Commonly used modules include shell module, copy module, cron module, etc.

-a: specify the parameters of the module

2. Copy module

Purpose: copy files to a remote host

Example:

[wangsn@m-ubonex-jenkins ~] $ansible-I / etc/ansible/hosts twm-m script-a'/ home/wangsn/useradd.sh'-- sudo-k [wangsn@m-ubonex-jenkins ~] $ansible-I / etc/ansible/hosts twm-m cron-a 'name= "test" minute= "0" hour= "5L2" job= "ls-alh > / dev/null"-sudo-k [wangsn@m-ubonex-jenkins ~] $ansible-I / etc/ Ansible/hosts twm-m cron-a 'name= "test" state=absent'-- sudo-k-Delete scheduled tasks

5. Fetch module (pull files)

Function: the file pull module mainly copies the files from the remote host to the local machine, which is the opposite of the function of the copy module.

Example:

[wangsn@m-ubonex-jenkins] $ansible-I / etc/ansible/hosts twm-m fetch-a "src=/opt/apache-tomcat-8.0.27 dest=/home/wangsn"-- sudo-k

Parameter description:

Src represents the file path that needs to be transferred on the remote host

Dest is represented as a path on the local machine.

The files transferred are classified according to the IP address, and then the path is the path of the source file.

Note: when pulling files, you must pull files, not folders.
