ansible hosts文件編寫，簡單使用測試（普通用戶、sudo用戶、root用戶登錄權限測試）

一、配置文件修改：

1、備份原配置文件：

cp /etc/ansible/hosts /etc/ansible/hosts.bak

2、修改hosts配置文件：

cat <<EOF>>/etc/ansible/hosts
[test]
10.10.10.1
10.10.10.2
10.10.10.3
[test1]
10.10.10.11
10.10.10.12
[test:vars]
ansible_ssh_user=test
ansible_ssh_pass=111111
ansible_su_pass=111111
ansible_sudo_user=test
ansible_sudo_pass=111111
[all:vars]
ansible_ssh_user=test
ansible_ssh_pass=123456
ansible_su_pass=123456
ansible_sudo_user=test
ansible_sudo_pass=123456

EOF

注：

1、可以不設置免密碼登錄，配置好ansible_ssh_user和ansible_ssh_pass即可

2、若想用登錄用戶test啟用sudo權限，登錄目標服務器：

執行visudo命令，最后一行加入 'test ALL=(ALL) ALL'即可。

或

echo 'test ALL=(ALL)       ALL' >>/etc/sudoers

( 不建議echo 'test ALL=(ALL)       NOPASSWD: ALL' >>/etc/sudoers ; sudo免密碼，普通用戶權限過大，有安全隱患)

二、測試

1、登錄用戶測試

[root@localhost vmuser]# ansible test -m ping
10.10.10.1 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
10.10.10.2 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
10.10.10.3 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

 

2、sudo權限測試

[root@localhost vmuser]# ansible test1 -m shell -a "fdisk -l |head -n2" -s 
10.10.10.11 | SUCCESS | rc=0 >>

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

10.10.10.12 | SUCCESS | rc=0 >>

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

 

3、su權限測試：

[root@localhost vmuser]# ansible all -S -R root -m shell -a "/sbin/fdisk -l |head -n2"
[DEPRECATION WARNING]: The su command line option has been deprecated in favor of the "become" command line arguments. This feature will be removed in version 2.6. 
Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
10.10.10.1 | SUCCESS | rc=0 >>

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

10.10.10.2 | SUCCESS | rc=0 >>

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

10.10.10.3 | SUCCESS | rc=0 >>

10.10.10.11 | SUCCESS | rc=0 >>

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

10.10.10.12 | SUCCESS | rc=0 >>
