Production Practice:
Use shell scripts to call ansible to perform batch operations

Study skills:
Shell script calls ansible, Ansible common modules use

Script content:
If there is no platform support in production, it is very common to operate remote hosts in batches in the central control. It is very convenient to use pssh if you have done ssh mutual trust authentication. mixed. pssh, ansible, saltstack, script, whichever is more applicable, or a combination. The following are several shell scripts that call ansible 2.9.25 to perform batch operations, which can be optimized as you like.
ansilbe_shell.sh : Use the ansible shell module to execute commands in batches
#!/bin/bash
#set -x
set -e
if [ $# -lt 2 ]; then
echo "Usage: ansible_shell <host1,hosts2,hostgroup> <commands>"
exit
the fi
hosts="*$1"
shift 1
commands="$*"
#commands=${*:2}
# ansible_sudo_pass can also be written in the ansible host configuration file, there is no need to add -e to write if [ -n "${commands}" ]; then
ansible $hosts -m shell -a "$commands;echo ' '" -e "ansible_sudo_pass=xxx" 2>/dev/null
the fi
exit
ansible_sync.sh : Use the ansible synchronize module to push files or folders to remote hosts in batches, or pull remote files back to the local
#!/bin/bash
