Ansible 安裝完且 SSH 環境準備好後就可以開始使用 Ansible CLI 去使用 Ansible。
Ansible CLI 的使用方式如下：
Usage: ansible [options]
Options: -a MODULE_ARGS, –args=MODULE_ARGS module arguments -k, –ask-pass ask for SSH password -K, –ask-sudo-pass ask for sudo password -B SECONDS, –background=SECONDS run asynchronously, failing after X seconds (default=N/A) -C, –check don’t make any changes; instead, try to predict some of the changes that may occur -c CONNECTION, –connection=CONNECTION connection type to use (default=smart) -f FORKS, –forks=FORKS specify number of parallel processes to use (default=5) -h, –help show this help message and exit -i INVENTORY, –inventory-file=INVENTORY specify inventory host file (default=/etc/ansible/hosts) -l SUBSET, –limit=SUBSET further limit selected hosts to an additional pattern –list-hosts outputs a list of matching hosts; does not execute anything else -m MODULE_NAME, –module-name=MODULE_NAME module name to execute (default=command) -M MODULE_PATH, –module-path=MODULE_PATH specify path(s) to module library (default=/usr/share/ansible) -o, –one-line condense output -P POLL_INTERVAL, –poll=POLL_INTERVAL set the poll interval if using -B (default=15) –private-key=PRIVATE_KEY_FILE use this file to authenticate the connection
-s, –sudo run operations with sudo (nopasswd) -U SUDO_USER, –sudo-user=SUDO_USER desired sudo user (default=root) -T TIMEOUT, –timeout=TIMEOUT override the SSH timeout in seconds (default=10) -t TREE, –tree=TREE log output to this directory -u REMOTE_USER, –user=REMOTE_USER connect as this user (default=vagrant) -v, –verbose verbose mode (-vvv for more, -vvvv to enable
connection debugging) –version show program’s version number and exit
比較常用的參數有 -i、-m、-a、-s，-i 用來指定 inventory file 或是管理機的位置，-m 用來指定要使用的模組，-a 用來指定模組所需要的參數，-s 用來指定需要用 sudo 運行。
像是用 IP 指定電腦去運行指定模組的動作，可以像這樣調用。
ansible -i , -m -a ""
要用 Inventory file 指定電腦去運行指定模組的動作，可以像這樣調用。
ansible -i , -m -a ""
可加上 -s 指定使用 sudo 運行。
ansible -i , -m -a "" -s
