常用參數： chdir 運行command命令前先cd到這個目錄 creates 當指定的這個參數對應的文件存在，就不行command命令，如果不存在，那么就運行command命令 案例： ~~~ [admin@node1 ~]$ ansible webserver -m command -a "chdir=/tmp touch aa01.txt" [WARNING]: Consider using file module with state=touch rather than running touch 192.168.52.130 | SUCCESS | rc=0 >> 192.168.52.132 | SUCCESS | rc=0 >> 192.168.52.131 | SUCCESS | rc=0 >> ~~~ ~~~ [admin@node1 ~]$ ansible webserver -m command -a "chdir=/tmp touch testfile.txt creates=/tmp/aa01.txt" 192.168.52.130 | SUCCESS | rc=0 >> skipped, since /tmp/aa01.txt exists 192.168.52.132 | SUCCESS | rc=0 >> skipped, since /tmp/aa01.txt exists 192.168.52.131 | SUCCESS | rc=0 >> skipped, since /tmp/aa01.txt exists ~~~
