# ansible 192.168.2.9 -m ping -u root 192.168.2.9 | success >> { "changed": false, "ping": "pong" }
使用通配符
# ansible 192.168.2.? -m ping -u root 192.168.2.9 | success >> { "changed": false, "ping": "pong" } # ansible 192.168.2.* -m ping -u root 192.168.2.12 | success >> { "changed": false, "ping": "pong" } 192.168.2.15 | success >> { "changed": false, "ping": "pong" } 192.168.2.9 | success >> { "changed": false, "ping": "pong" } 192.168.2.11 | success >> { "changed": false, "ping": "pong" }
制定一個hosts檔案
# echo '192.168.6.10' >> hosts # cat hosts 192.168.6.10 # ansible all -a 'echo hello' -i hosts -u root 192.168.6.10 | success | rc=0 >> hello
