A, ansible optimization
/etc/ansible/ansible.cfg Vim host_key_checking # = False not validated log_path = /var/log/ansible.log # open log
Based ssh
vim /etc/ssh/sshd_config UseDNS no #重启sshd # systemctl restart sshd
Second, the common module
1, coyp module
ansible date -m copy -a 'src=/etc/selinux/config dest=/etc/selinux/confi
2, fetch fetch files from the client module
ansible date -m fetch -a "src=/var/log/cron dest=/data/"
3, shell module (Run, or remote script execution), and so instead of file module
ansible date -m shell -a 'cat /etc/selinux/config'
4, script module (not need to have remote script, the control terminal can have)
ansible date -m script -a "/root/scripts/test.sh" [root@linux-node1 scripts]# cat /root/scripts/test.sh #!/bin/bash hostname
