ansible基本应用

1. ansible特性：

• ansible糅合了很多老牌运维东西的优点，根本上pubbet和saltstack能结束的功能悉数能结束。
• 安置简略：不需求在被管控主机上设备任何客户端，操作客户端时直接作业指令。
• 依据python言语结束，有Paramiko, PyYAML和Jinja2三个要害模块。
• 模块化：调用特定模块结束特定使命。可运用任意言语开发模块，且支撑自界说模块。
• 运用yaml言语定制剧本playbook。
• 依据SSH作

2. ansibl线程e的模块

• connection plugins：联接插件，经过ssh办法
• host inventory：主机清单，要处理的主机
• playbooks：剧本，yaml格局的配备文件线程撕裂者
• core modules：核NPM心模块
• custom modules：自界说模http 302块
• plugins：插件
  – emailhttps认证：发送邮件。
  – loggings：记录日志

4. ansible指令的运用：https和http的差异

[root@nfs ~]# ansible -h
Usage: ansible <host-pattern> [opti线程池面试题ons]
Option线程和进程的差异是什么s:
-a MODULE_ARGS, --args=MO线程安全DULE_A线程安全RGS
module arguments   模块参数
-C, --check           don't make any changes; instead, try to predict some

-b, --become          run operations withhttps域名 become (does not imply password prompting)

5. 界说主机列表：

示例1. 经过直接指定主机名或IP地址界说主https和http的差异机列表。

# Ex 1: Ungrouped线程安全 hosts, specify before any gro女配没有求生欲up headers.

## green.examphttpclientle.com
## blue.example.com
## 192.168.100.1
## 192.168.100.10

示例2. 先界说组名，再在线程池面试题组下填入主机名或IP地址

# Ex 2: A collection of hosts belonging to the 'webser男配每天都在体内成果vers' group

## [webse女配没有求生欲rvers]
## alpha.example.org
## bethttp://www.baidu.coma.example.org
## 192.168.1.100
## 192.168.1.110

# If you have multiple hosts following a pattern you can specify
# them like this:
# 假定有多个接连主机，也可用如下办法指http署理定主机。

#女配每天都在为国争光# www[001:006].example.com

示例3.

# Ex 3: A coll缓存视频怎样转入本地视频ection of database servers in the 'dbservers' group

## [dbserhttps认证vhttpwatcher缓存视频怎样下载到手机相册s]

## db01.intranet.mydomain.net
## db02.intranet.mydo缓存视频怎样转入相册main.net
## 10.25.1.56缓存视频在手机哪里找
## 10.25.1.57

# Here's another example of host ranges,https协议 this time th线程池的七个参数ere are no
# leading 0s:

## db-[99:101]-no缓存的视频怎样保存到本地de.example.com
## 以上写法可扩展为如下主机：
## db-99-nod.example.com
## db-100-nod.example.com
## db-101-nod.example.com

6.1 ping模块：勘探长途主机

[root@nfs ~]# ansible-doc -s ping
- name: Trhttps域名y to connect to host, verify a usable python and return `pong' on success
# 测验联接主机，若方针主机可用，就回应一个'pong'
ping:
data:           # Data to return for the `pinhttp 404g' return value. If this parameter is set to `cras线程和进程的差异是什么h', the module will cause an exception.

**示例1：**向悉数可控主机主张ping线程池的七个参数操作

[root@n线程和进程的差异是什么fs ~]# ansible all -m ping
np2女配每天都在为国争光.lxk.com | SUCCESS => {

6.2 command模块：在长途主机缓存数据能够铲除吗上作业指令

模块用法：
关于command来说，要运用哪个指令，运用-a选项，直接给出指令本身即可。

例1：创立临时文件

[root@nfs ~]http://www.baidu.com# ansible all -m command -a "mktemp /tmp/abc.XXXX"
nfs.lxk.com | SUCCESS | rc=0 >>
/tmp/abc.Xyz7
np2.lxk.com | SUCCESS | rc=0 >>
/tm缓存视频怎样下载到手机相册p/abc.lwqo
np1.lxk.com | SUCCESS | rc=0 >>
/tmp/abc.jjHW

例2：创立用户

[root@nfs ~]# ansible all -m command -a "useradd user1"     # 第一次创立成功
nfs.lxk.com | SUCCESS | rc线程池创立的四种=0 >>
np1.lxk.com | SUCCESS | rc=0 >>
np2.lxk.com | SUCCESS | rc=0 >>
[rhttpwatchoot@nfs ~]# ansible all -m commanhttpclientdhttp协议 -a "useradd user1"        #第2次创立相同用http 302户失利
nfs.https认证lxk.com | FAILED | rc=9 >>
useradd: user 'user1' already existsnon-zero return code
np1.lxk.com | FAILED | rc=9 >>
useradd: user 'user1' already existsnon-zero return code
np2.lxk.女配美炸天com | FAILED | rc=9 >>
useraddhttp 302: ushttp协议er 'user1' already existsnon-zero return code

用加条件判别创立用户失利缓存视频兼并，因||是直接发给方针主机内核作业，不是经由shell作业，而||是shhttp协议ell的内置指令。

[root@nfs ~]# ansible all -m command -a "id user1 || useradd user1"
nfs.lxk.com | FAILED | rc=1 >>
id: extra operand ‘||’
Try 'id --help' for more information.non-zero retur女配满眼都是钱n code
np1.lxk.com缓存视频兼并 | FAILED |线程和进程的差异是什么 rc=1 >>
id: extra op女配没有求生欲erand ‘||’
Try 'id --help' for more information.non-zero return code
np2.lxk.com | FAILED | rc=1 >&http://www.baidu.comgt;
id: extra operand ‘||’
Try 'id --help' for mor缓存视频兼并e information.non-zero return code

6.3 shell模块：在节点中履行指令

与c线程撕裂者ommand模块很类似，所不同处是它是在shell下作业的。还可运用executable切换至指女配没有求生欲藤萝为枝定node下作业指令。
**例：**加条件判别创立用户

[root@nfs ~]# ansible all -m shell -a "id user1 || useradd user1"
np2.lxk.com | SU女配没有求生欲晋江CCESS | rc=0 >>httpclient
uid=1001(uhttpwatchser1) gid=1001(user1) groups=1001(user1)
nfs.lxk.com | SUCCESS | rc=0 >>
uid=1000(user1) gid=1000(user1) groups=1000(user1)
np1.lxk.com | SUCCESS | rc=0 >>
uid=1000(user1) gid=1000(user1) groups=1000(user1)

6.4 group模块：增加或删去组

group模块用法：

[root@nfs ~]# ansible-doc -s group
- name: Add or remove groups
group:
gid:                   # Op线程池原理tional `GID' to set fo线程池的七个参数r the group.是否运用自界说httpwatch的id号
name:                  # (required) Name of the group to女配每天都在抱大腿我要成仙 manage. 要处理的组名，必需求界说的。
state:                 # Whether the group should be present or not on the remote host.  状况信息，决定是删去仍是增加。创立:present，删去：absent
system:                # If `yehttp协议s', indicates that the group created is a system group缓存.   是否创立体系用户

**示例：**创立一个体系组

[root@nfs ~女配满眼都是钱]# ansible np1.lxk.com -女配每天都在抱大腿我要成仙m group -a 'name=mygrp gid=200 system=yes'
np1.lxk.com | SUCCESS => {
"changed": true,        #改动：成功
"gid": 200,             #自界说组ID：200
"name": "mygrp",        #组名：mygrp
"state缓存视频怎样下载到手机相册": "present"线程池原理,     #状况：增加
"system": true          #是否为体系用户：是
}

**示例：**删去组

[root@nfs ~]# ansible np1.lxk.com -m group -a 'name=女配没有求生欲晋江mygrp state=absent'
np1.lxk.com | SUCCESS => {
"changed": true,
"nahttp协议me": "mygrp",
"state": "absent"
}

上面指令重复履行时，changed状况为false。

[root@nfs ~]# ansible np1.lxk.com -m group -a 'name=mygrp state=absent'
np1.lxk.com | SUCCESS => {
"changedhttp 302": false,
"name": "mygrp",
"state": "absent"
}

6.5 user模块：处理用户帐户

模块内置指令一堆，请自行检查，根本见名知意。
**示例：**创立一个用户，姓名为tom，用户ID为2000，组名为mygrp，shell类型为/bin/bash，状况为增加。

[root@nfs ~]# ansible np1.lxk.com -m user -a 'name=tom state=present uid=2000 groups=mygrp shellNPM=/bihttpwatchn/bash'
np1.lxk.com | SUCCESS => {
"changed": true,
"comment": "",
"create_home": true,
"group": 2000,
"groups": "m线程池ygrp",
"home": "/home/tom",
"name": "tom线程和进程的差异是什么",
"shell"http 302: "/bin/bash",
"state": "presenthttp署理",
"system": false女配没有求生欲藤萝为枝,
"uid": 2000
}

**示例：**修改tom用户的ID为2020，shell类型为/bin/t缓存视频怎样转入本地视频csh

[root@nfs ~]# ansible np1.lxk.com -m user -a 'name=tom state=prese线程撕裂者nt uid=2020 groups=mygrp shell=/bhttps域名in/tcsh'
np1.lxk.com | SUCCESS => {
"append": f女配没有求生欲晋江alse,
"changed": true,
"comment": "",
"gr女配没有求生欲藤萝为枝oup": 2000,
"groups": "mygrp",线程的几种状况
"home": "/home/tom",
"move_home": false,
"nhttp://192.168.1.1登录ame": "tom",
"shell": "/bin/tcsh",
"state": "present",
"uid": 2020
}

6.线程池面试题6 copy模块

[root@nfs ~]# ansible-doc -s copy
- name: Copies files to remote locations        #复制一个或多个文件至长途主机
copy:
dest:                  # (required) Remote absolute path where线程池面试题 the file shou缓存视频在手机哪里找ld be co线程是什么意思pied to. If `src' is a directory, this must be a directory too. If `dest女配没有求生欲藤萝为枝' is a nonexistent path and if eithttp 404her `deshttps安全问题t' ends with "/" ohttps和http的差异r `src' is a线程池原理 dirhttp 302ectory, `dest' is created.

#复制指定文件至方针长途需求是肯缓存视频兼并app下载定途径。假定src是目录，dest也有必要是目录。假定dest是一个不存在的途径，并且dest不以/结束或许src是个目录，dest会自动创立。假定src和dest都是多个文件，dest的父目录没创立，复制就女排名单会失利。
src:                   # Local path to a file to copy to the remote server; can be absolu线程是什么意思te or relative.httpwatch If path is a directory, it is copied recursively.

Otherwise, if it does女配美炸天 not end with "/", thttp://192.168.1.1登录he directory itself with all contents is copied. This behavior is similar to Rsync.
#本线程撕裂者地需求复制到长途主机的文件的途径。可所以必定途径，也可所以相对途径。假定途径是个目录，则递归复制。假定途径以/https认证结束，只复制目录下的文件至方针女配美炸天途径。假定不http署理以/结束，则会把目录以及其下的内容都复制至方针主机。这种行为类似于rsync。
conten女配每天都在抱大腿我要成仙t:               # When used instead of `src', sets the contents of a file directly to the specified value. For anything advance女配没有求生欲txtd or with formatt缓存视频兼并app下载ing also look at the template module.女配美炸天
#假定不运用src而运用content，把文件内容直接指定为content所指定的内容。然后剩余的懒得翻译了。
owner:                 # Name of the user tha女配没有求生欲txtt should own the file/directory, as would be fed to `chown'.

检查方针主机上的http协议文件：http署理

6.7 fetch模块

[root@nfs ~]# ansible-doc -s fetch
