知识点:使用module command或者shell或者raw都能调用对象机器上的某条指令或者某个可执行文件。
使用方法
[root@host31 ~]# ansible localhost -m command -a "echo hello"localhost | SUCCESS | rc=0 >>hello[root@host31 ~]# ansible localhost -m shell -a "echo hello"localhost | SUCCESS | rc=0 >>hello[root@host31 ~]# ansible localhost -m raw -a "echo hello"localhost | SUCCESS | rc=0 >>hello[root@host31 ~]#

是否支持管道
module | 是否支持管道 |
---|---|
command | 不支持管道 |
shell | 支持管道 |
raw | 支持管道 |
[root@host31 ~]# ansible localhost -m command -a "ps -ef |wc -l"localhost | FAILED | rc=1 >>error: garbage optionUsage: ps [options] Try 'ps --help <simple|list|output|threads|misc|all>' or 'ps --help <s|l|o|t|m|a>' for additional help text.For more details see ps(1).[root@host31 ~]# ansible localhost -m shell -a "ps -ef |wc -l"localhost | SUCCESS | rc=0 >>448[root@host31 ~]# ansible localhost -m raw -a "ps -ef |wc -l"localhost | SUCCESS | rc=0 >>445[root@host31 ~]#

直接执行某个文件
[root@host31 ~]# ansible host32 -m command -a "/tmp/ttt.sh"host32 | SUCCESS | rc=0 >>hello world[root@host31 ~]# ansible host32 -m raw -a "/tmp/ttt.sh"host32 | SUCCESS | rc=0 >>hello world[root@host31 ~]# ansible host32 -m shell -a "/tmp/ttt.sh"host32 | SUCCESS | rc=0 >>hello world[root@host31 ~]#

都是支持的,但是需要注意/tmp/ttt.sh应该有执行权限
ansible-doc -s取得更详细信息
希望知道更加详细的module的信息,最好的方法是使用ansible自带的ansible-doc的-s选项
[root@host31 ~]# ansible-doc -s raw- name: Executes a low-down and dirty SSH command action: raw executable # change the shell used to execute the command. Should be an absolute path to the executable. free_form= # the raw module takes a free form command to run[root@host31 ~]#[root@host31 ~]# ansible-doc -s shell- name: Execute commands in nodes. action: shell chdir # cd into this directory before running the command creates # a filename, when it already exists, this step will *not* be run. executable # change the shell used to execute the command.
