2. Sequential Execution: The Shell module executes multiple commands sequentially, ensuring that dependencies between commands are maintained. This is particularly useful when there is a need to run commands in a specific order or when the output of one command is required as input for another comm...
此外,shell模块还可以利用 shell 的其他特性,如条件判断和循环。例如,以下是一个使用条件判断的示例: - name: Conditional execution in shell shell: | if [ -f /path/to/file ]; then echo "File exists" else echo "File does not exist" fi 在这个例子中,shell模块使用了 shell 的条件判断语句来检查...
1.2.1 shell和command 默认ansible使用的模块是command,即可以执行一些shell命令。shell和command的用法基本一样,实际上shell模块执行命令的方式是在远程使用/bin/sh来执行的,如/bin/sh ping。 command不能解析变量(如$HOME)和某些操作符(“<“, “>”, “|”, “;”以及”&”),所以明确要使用这些不可解析的...
-m 在Ansible中有用到模块(module)的概念,用-m参数来指定。默认是command模块。如果被ansible访问的设备本身已经安装并支持python, 那么就可以使用command或者shell这两个模块来管理该设备,如果被访问的设备没有安装python,比如老旧的思科2960,3750等交换机,这时就必须用raw这个模块来访问该设备。更多关于Ansible模块的信...
Multiple path globs can be specified and are separated by :. Currently only used for remote coverage on PowerShell modules. This is for internal use only. Type: str Default: * Version Added: 2.9 Environment: Variable: _ANSIBLE_COVERAGE_REMOTE_PATH_FILTER DEFAULT_ACTION_PLUGIN_PATH ...
shell: 为指定的用户指定一个默认登录shell; 示例: [root@3 ~]# ansible all -m user -a "name=testuser02 system=yes uid=333 create_home=no shell=/sbin/nologin state=present" [root@3 ~]# ansible all -m user -a "name=testuser01 state=absent remove=yes" 4.group模块: Add or remove ...
#module_name = command # use this shell for commands executed under sudo # you may need to change this to bin/bash in rare instances # if sudo is constrained #executable = /bin/sh # if inventory variables overlap, does the higher precedence one win ...
匹配模式:即哪些机器生效 (可以是某一台, 或某一组, 或all) , 默认模块为 command , 执行常规的shell命令. -a MODULE_ARGS #模块的参数,如果执行默认COMMAND的模块,即是命令参数,如: “date”,“pwd”等等 -k,--ask-pass #ask for SSH password。登录密码,提示输入SSH密码而不是假设基于密钥的验证 -...
-a MODULE_ARGS --args=MODULE_ARGS 传递参数给模块 --ask-vault-pass 询问vault的密码 -B SECONDS --background=SECONDS 异步后台方式执行任务,并在指定的秒数后超时,超时会杀掉任务的进程。默认是同步,即保持长连接,它会等待所有执行完毕(即阻塞模式)。但有时候是没必要这样的,比如某些命令的执行时间比ssh的...
Choosing Command or Shell Thewin_shellandwin_commandmodules can both be used to execute a command or commands. Thewin_shellmodule is run within a shell-like process likePowerShellorcmd, so it has access to shell operators like<,>,|,;,&&, and||. Multi-lined commands can also be run...
