（1）列出 ansible 支援的子產品
（2）檢視該子產品的幫助資訊
以下實驗均是在 IP 位址為： 192.168.91.128 的虛拟機上操作的。
/etc/ansible/hosts 檔案中配置如下：
# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
# - Comments begin with the '#' character
# - Blank lines are ignored
# - Groups of hosts are delimited by [header] elements
# - You can enter hostnames or ip addresses
# - A hostname/ip can be a member of multiple groups
# Ex 1: Ungrouped hosts, specify before any group headers.
## green.example.com
## blue.example.com
## 192.168.100.1
## 192.168.100.10
[Client]
# Ex 2: A collection of hosts belonging to the 'webservers' group
## [webservers]
## alpha.example.org
## beta.example.org
## 192.168.1.100
## 192.168.1.110
# If you have multiple hosts following a pattern you can specify
# them like this:
## www[001:006].example.com
# Ex 3: A collection of database servers in the 'dbservers' group
## [dbservers]
##
## db01.intranet.mydomain.net
## db02.intranet.mydomain.net
## 10.25.1.56
## 10.25.1.57
# Here's another example of host ranges, this time there are no
# leading 0s:
## db-[99:101]-node.example.com
常用子產品示例
ping 子產品
檢查指定節點機器能否連通，如果主機線上，則回複pong。
例如：
[root@xdhuxc ~]# ansible Client -m ping
| SUCCESS => {
"changed": false,
"ping": "pong"
}
[root@xdhuxc ~]#
遠端指令子產品（command、script、shell）
command 作為 ansible 的預設子產品，可以運作遠端權限範圍所有的 shell 指令，不支援管道符。
例如：
執行結果為：
[root@xdhuxc ~]# ansible Client -m command -a "free -h"
.91.130 | SUCCESS | rc= >>
total used free shared buff/cache available
Mem: M M M M M M
Swap: G B G
script 的功能是在遠端主機執行主要端存儲的 shell 腳本檔案，相當于 scp + shell 組合。
例如：
xdhuxc.sh 腳本的内容為：
[[email protected] ~]# pwd
/root
[[email protected] ~]# ls
xdhuxc.sh
[[email protected] ~]# cat xdhuxc.sh
#!/usr/bin/env bash
echo "Hello Shell."
echo $1
echo $2 >> /root/abc.sh
執行結果為：
[root@xdhuxc ~]# ansible Client -m script -a "/root/xdhuxc.sh string buffer"
| SUCCESS => {
"changed": true,
"rc": ,
"stderr": "Shared connection to 192.168.91.130 closed.\r\n",
"stdout": "Hello Shell.\r\nstring\r\n",
"stdout_lines": [
"Hello Shell.",
"string"
]
}
在 192.168.91.130上，在 root 目錄下，會産生 abc.sh 檔案。
[root@xdhuxc ~]# pwd
/root
[root@xdhuxc ~]# ls
abc.sh anaconda-ks.cfg ~None
[root@xdhuxc ~]# cat abc.sh
buffer
[root@xdhuxc ~]#
~None 目錄下
[root@xdhuxc ~None]# pwd
/root/~None
[root@xdhuxc ~None]# tree -a
.
└── .ansible
└── tmp
directories, files
shell 的功能是執行遠端主機上的 shell 腳本檔案，支援管道符。
例如：
在 root 目錄下建立 xdhuxc.sh 檔案，
[[email protected] ~]# pwd
/root
[[email protected] ~]# ll
total
-rw-r--r-- root root Jun : abc.sh
-rw-------. root root Apr : anaconda-ks.cfg
drwx------ root root Jun : ~None
-rw-r--r-- root root Jun : xdhuxc.sh # xdhuxc.sh 沒有執行權限。
[[email protected] ~]# cat xdhuxc.sh
#!/usr/bin/env bash
echo -n "Hello World!"
在 xdhuxc.sh 沒有被賦予執行權限時，執行 ansible 指令。
[root@xdhuxc ~]# ansible Client -m shell -a "/root/xdhuxc.sh"
. | FAILED | rc= >>
/bin/sh: /root/xdhuxc.sh: Permission deniednon-zero return code
很明顯，xdhuxc.sh 沒有可執行權限導緻的，修改該指令，重新執行，指令執行成功。
[[email protected] ~]# ansible Client -m shell -a "chmod +x /root/xdhuxc.sh ; /root/xdhuxc.sh"
[WARNING]: Consider using the file module with mode rather than running chmod. If you need to use command because
file is insufficient you can add warn=False to this command task or set command_warnings=False in ansible.cfg to
get rid of this message.
| SUCCESS | rc= >>
Hello World!
copy 子產品
copy 子產品用于實作主要端向目标機器複制檔案，類似于 scp 功能。
例如：
執行結果如下：
[root@xdhuxc ~]# pwd
/root
[root@xdhuxc ~]# ls
xdhuxc.sh
[root@xdhuxc ~]# ansible Client -m copy -a "src=/root/xdhuxc.sh dest=/tmp/ owner=root group=root mode=0755"
| SUCCESS => {
"changed": true,

directories, files
[root@xdhuxc ~None]# ls /tmp
xdhuxc.sh
stat 子產品
stat 子產品用于擷取遠端檔案狀态資訊，atime/ctime/mtime/md5/uid/gid等資訊。
例如：
執行結果如下：
[root@xdhuxc ~]# ansible Client -m stat -a "path=/etc/resolv.conf"
| SUCCESS => {
"changed": false,
"stat": {
"atime": ,
"attr_flags": "",
"attributes": [],
"block_size": ,

}
}
顯示了 /etc/sysctl.conf 檔案的所有狀态資訊。

例如：
執行指令的結果為：
[root@xdhuxc ~]# ansible Client -m get_url -a "url=http://www.baidu.com dest=/tmp/index.html mode=0440 force=yes"
| SUCCESS => {

user 子產品
user 子產品用來進行遠端主機使用者的管理。
例如：
ansible Client -m user -a "name=wang comment='user wang'" # 建立使用者 wang
ansible Client -m user -a "name=wang state=absent remove=yes" # 删除使用者 wang
執行指令結果如下：
[root@xdhuxc ~]# cat /etc/passwd | grep wang
[root@xdhuxc ~]# ansible Client -m user -a "name=wang comment='user wang'" # 建立使用者 wang
| SUCCESS => {
"changed": true,
"comment": "user wang",
"create_home": true,
"group": ,
"home": "/home/wang",
"name": "wang",
"shell": "/bin/bash",
"state": "present",
"system": false,
"uid":
}
[root@xdhuxc ~]# cat /etc/passwd | grep wang

[root@xdhuxc ~]# ansible Client -m user -a "name=wang state=absent remove=yes" # 删除使用者 wang
