Ansible之常用模块（二）
1、hostname：此模块的主要作用是管理远端节点主机名
模块帮助：
root@localhost ~]# ansible-doc -s hostname
- name: Manage hostname
hostname:
name: # (required) Name of the host
[root@localhost ~]#
说明：通常我们使用这个模块是在playbook里使用，通过一些变量的控制，给定不同的主机以不同的主机名。
常用参数说明：
name：指定远端节点主机名称
[root@localhost ~]# ansible 192.168.0.99 -m shell -a 'hostname'
192.168.0.99 | SUCCESS | rc=0 >>
docker [root@localhost ~]# ansible 192.168.0.99 -m hostname -a 'name=test'
192.168.0.99 | SUCCESS => {
"ansible_facts": {
"ansible_domain": "",
"ansible_fqdn": "test",
"ansible_hostname": "test",
"ansible_nodename": "test"
},
"changed": true,
"name": "test"
}
[root@localhost ~]# ansible 192.168.0.99 -m shell -a 'hostname'
192.168.0.99 | SUCCESS | rc=0 >>
test [root@localhost ~]#
说明：以上命令是给192.168.0.99这台主机更改主机名
2、cron：此模块的主要作用是管理计划任务
模块帮助：
[root@localhost ~]# ansible-doc -s cron
- name: Manage cron.d and crontab entries.
cron:
backup: # If set, create a backup of the crontab before it is modified. The location of the backup is returned in
the `backup_file' variable by this module.
cron_file: # If specified, uses this file instead of an individual user's crontab. If this is a relative path, it is
interpreted with respect to /etc/cron.d. (If it is absolute, it will
typically be /etc/crontab). Many linux distros expect (and some require)
the filename portion to consist solely of upper- and lower-case letters,
digits, underscores, and hyphens. To use the `cron_file' parameter you
must specify the `user' as well.
day: # Day of the month the job should run ( 1-31, *, */2, etc )
disabled: # If the job should be disabled (commented out) in the crontab. Only has effect if state=present
env: # If set, manages a crontab's environment variable. New variables are added on top of crontab. "name" and
"value" parameters are the name and the value of environment variable.
hour: # Hour when the job should run ( 0-23, *, */2, etc )
insertafter: # Used with `state=present' and `env'. If specified, the environment variable will be inserted after the
declaration of specified environment variable.
insertbefore: # Used with `state=present' and `env'. If specified, the environment variable will be inserted before the
declaration of specified environment variable.
job: # The command to execute or, if env is set, the value of environment variable. The command should not
contain line breaks. Required if state=present.
minute: # Minute when the job should run ( 0-59, *, */2, etc )
month: # Month of the year the job should run ( 1-12, *, */2, etc )
name: # Description of a crontab entry or, if env is set, the name of environment variable. Required if
state=absent. Note that if name is not set and state=present, then a new
crontab entry will always be created, regardless of existing ones.
reboot: # If the job should be run at reboot. This option is deprecated. Users should use special_time.
special_time: # Special time specification nickname.
state: # Whether to ensure the job or environment variable is present or absent.
user: # The specific user whose crontab should be modified.
weekday: # Day of the week that the job should run ( 0-6 for Sunday-Saturday, *, etc )
[root@localhost ~]#
常用参数说明：
backup:是否备份之前的计划任务，默认为no

说明：state=absent是从用户的计划任务列表中删除计划任务，它不是把计划任务给注释掉，而是删除。删除计划任务只需指定计划任务名称以及用户就可以，若没有指定用户，它默认是root用户。
disabled：是否禁用计划任务（被注释），此选项只能在state=present的时候才有效

说明：此选项必须指定以那个用户创建的计划任务。
3、yum：此模块主要功能是使用“yum”包管理器管理包
模块帮助：
[root@localhost ~]# ansible-doc -s yum
- name: Manages packages with the `yum' package manager
yum:
allow_downgrade: # Specify if the named package and version is allowed to downgrade a maybe already installed higher version of
that package. Note that setting allow_downgrade=True can make this module
behave in a non-idempotent way. The task could end up with a set of packages
that does not match the complete list of specified packages to install
(because dependencies between the downgraded package and others can cause
changes to the packages which were in the earlier transaction).
conf_file: # The remote yum configuration file to use for the transaction.
disable_gpg_check: # Whether to disable the GPG checking of signatures of packages being installed. Has an effect only if state is
`present' or `latest'.
disablerepo: # `Repoid' of repositories to disable for the install/update operation. These repos will not persist beyond the
`present' or `latest'.
disablerepo: # `Repoid' of repositories to disable for the install/update operation. These repos will not persist beyond the
transaction. When specifying multiple repos, separate them with a ",".
enablerepo: # `Repoid' of repositories to enable for the install/update operation. These repos will not persist beyond the
transaction. When specifying multiple repos, separate them with a ",".
exclude: # Package name(s) to exclude when state=present, or latest
installroot: # Specifies an alternative installroot, relative to which all packages will be installed.
list: # Package name to run the equivalent of yum list <package> against.
name: # (required) Package name, or package specifier with version, like `name-1.0'. If a previous version is
specified, the task also needs to turn `allow_downgrade' on. See the
`allow_downgrade' documentation for caveats with downgrading packages. When
using state=latest, this can be '*' which means run `yum -y update'. You can
also pass a url or a local path to a rpm file (using state=present). To
operate on several packages this can accept a comma separated list of packages
or (as of 2.0) a list of packages.
security: # If set to `yes', and `state=latest' then only installs updates that have been marked security related.
skip_broken: # Resolve depsolve problems by removing packages that are causing problems from the trans‐ action.
state: # Whether to install (`present' or `installed', `latest'), or remove (`absent' or `removed') a package.
update_cache: # Force yum to check if cache is out of date and redownload if needed. Has an effect only if state is `present'
or `latest'.
validate_certs: # This only applies if using a https url as the source of the rpm. e.g. for localinstall. If set to `no', the
SSL certificates will not be validated. This should only set to `no' used on
personally controlled sites using self-signed certificates as it avoids
verifying the source site. Prior to 2.1 the code worked as if this was set to
`yes'.
[root@localhost ~]#
常用参数说明：
name:指定包的名称
state:指定是对包的操作，present或者installed或者latest 都表示安装，latest表示安装最新版本的包；absent或者removed表示删除，卸载，默认是present
list:类似yum list 包名 这条命令

说明：安装包可以不用跟后面的state=present，因为我们不写默认就是present；安装包的时候name也可以指定从远程仓库里安装某一个包，比如name=https://xxx/包名.rpm。也可以从本地光盘安装，比如name=/file/to/package.rpm;同时也可以指定安装某个包组的包，比如name="@Development tools"；当然这个模块只能用于支持yum包管理的Linux系统（redhat系列），ubuntu需要用apt这个模块进行包的管理，用法同yum类似。

4、service：此模块主要功能是管理服务
模块帮助：
[root@localhost ~]# ansible-doc -s service
- name: Manage services.
service:
arguments: # Additional arguments provided on the command line
enabled: # Whether the service should start on boot. *At least one of state and enabled are required.*
name: # (required) Name of the service.
pattern: # If the service does not respond to the status command, name a substring to look for as would be found in the
output of the `ps' command as a stand-in for a status result. If the string
is found, the service will be assumed to be running.
runlevel: # For OpenRC init scripts (ex: Gentoo) only. The runlevel that this service belongs to.
sleep: # If the service is being `restarted' then sleep this many seconds between the stop and start command. This
helps to workaround badly behaving init scripts that exit immediately after
signaling a process to stop.
state: # `started'/`stopped' are idempotent actions that will not run commands unless necessary. `restarted' will
always bounce the service. `reloaded' will always reload. *At least one of
state and enabled are required.* Note that reloaded will start the service if
it is not already started, even if your chosen init system wouldn't normally.
use: # The service module actually uses system specific modules, normally through auto detection, this setting can
force a specific module. Normally it uses the value of the
'ansible_service_mgr' fact and falls back to the old 'service' module when
none matching is found.

常用参数说明：
enabled:是否开机启动
name:指定服务名称
state：指定对服务的操作，started表示启动服务，stopped表示停止服务，restarted表示重启服务，reloaded表示重新加载配置文件，切记没有status这个值
1）启动httpd服务

说明：本人测试是一台centos6和一台centos7，两个系统查询开机启动的命令不同。所以分两次来查看不同系统的服务开机启动是否设置成功，重启服务和重读配置文件的参数同启动服务，停止服务用法一样，只需要在state后面指定它的动作。
5、user：此模块主要功能是管理用户
模块帮助：
[root@localhost ~]# ansible-doc -s user
- name: Manage user accounts
user:
append: # If `yes', will only add groups, not set them to just the list in `groups'.
comment: # Optionally sets the description (aka `GECOS') of user account.
createhome: # Unless set to `no', a home directory will be made for the user when the account is created or if the home
directory does not exist.
expires: # An expiry time for the user in epoch, it will be ignored on platforms that do not support this. Currently
supported on Linux and FreeBSD.
force: # When used with `state=absent', behavior is as with `userdel --force'.
generate_ssh_key: # Whether to generate a SSH key for the user in question. This will *not* overwrite an existing SSH key.
group: # Optionally sets the user's primary group (takes a group name).
groups: # Puts the user in list of groups. When set to the empty string ('groups='), the user is removed from all
groups except the primary group. Before version 2.3, the only input format
allowed was a 'comma separated string', now it should be able to accept YAML
lists also.
home: # Optionally set the user's home directory.
local: # Forces the use of "local" command alternatives on platforms that implement it. This is useful in environments
that use centralized authentification when you want to manipulate the local
users. I.E. it uses `luseradd` instead of `useradd`. This requires that these
commands exist on the targeted host, otherwise it will be a fatal error.
login_class: # Optionally sets the user's login class for FreeBSD, OpenBSD and NetBSD systems.
move_home: # If set to `yes' when used with `home=', attempt to move the user's home directory to the specified directory
if it isn't there already.
name: # (required) Name of the user to create, remove or modify.
non_unique: # Optionally when used with the -u option, this option allows to change the user ID to a non-unique value.
password: # Optionally set the user's password to this crypted value. See the user example in the github examples
directory for what this looks like in a playbook. See
http://docs.ansible.com/ansible/faq.html#how-do-i-generate-crypted-passwords-
for-the-user-module for details on various ways to generate these password
values. Note on Darwin system, this value has to be cleartext. Beware of
security issues.
remove: # When used with `state=absent', behavior is as with `userdel --remove'.
seuser: # Optionally sets the seuser type (user_u) on selinux enabled systems.
shell: # Optionally set the user's shell.
skeleton: # Optionally set a home skeleton directory. Requires createhome option!
ssh_key_bits: # Optionally specify number of bits in SSH key to create.
ssh_key_comment: # Optionally define the comment for the SSH key.
ssh_key_file: # Optionally specify the SSH key filename. If this is a relative filename then it will be relative to the
user's home directory.
ssh_key_passphrase: # Set a passphrase for the SSH key. If no passphrase is provided, the SSH key will default to having no
passphrase.
ssh_key_type: # Optionally specify the type of SSH key to generate. Available SSH key types will depend on implementation
present on target host.
state: # Whether the account should exist or not, taking action if the state is different from what is stated.
system: # When creating an account, setting this to `yes' makes the user a system account. This setting cannot be
changed on existing users.
uid: # Optionally sets the `UID' of the user.
update_password: # `always' will update passwords if they differ. `on_create' will only set the password for newly created
users.

"name": "jerry",
"remove": true,
"state": "absent"
}
192.168.0.99 | SUCCESS => {
"changed": true,
"force": false,
"name": "jerry",
"remove": true,
"state": "absent"
}
[root@localhost ~]# ansible websers -m shell -a 'id jerry'

ls: cannot access /var/log/jerry: No such file or directorynon-zero return code [root@localhost ~]#
说明：remove参数表示连同用户家目录一起删除，等同于userdel -r这条命令
6、group：此模块主要功能是管理组
模块帮助：
[root@localhost ~]# ansible-doc -s group
- name: Add or remove groups
group:
gid: # Optional `GID' to set for the group.
name: # (required) Name of the group to manage.
state: # Whether the group should be present or not on the remote host.
system: # If `yes', indicates that the group created is a system group.
[root@localhost ~]#
常用参数说明：
gid:指定gid
name:指定组名
system:是否为系统组，默认no
state:指定对组的操作，absent表示删除，present表示创建，默认present
1）创建组
[root@localhost ~]# ansible websers -m shell -a 'getent group xxx'
192.168.0.218 | FAILED | rc=2 >>
non-zero return code 192.168.0.99 | FAILED | rc=2 >>
non-zero return code [root@localhost ~]# ansible websers -m group -a 'name=xxx system=yes'
192.168.0.218 | SUCCESS => {
"changed": true,
"gid": 493,
"name": "xxx",
"state": "present",
"system": true
}
192.168.0.99 | SUCCESS => {
"changed": true,
"gid": 983,
"name": "xxx",
"state": "present",
"system": true
}
[root@localhost ~]# ansible websers -m shell -a 'getent group xxx'
192.168.0.218 | SUCCESS | rc=0 >>
xxx:x:493: 192.168.0.99 | SUCCESS | rc=0 >>
xxx:x:983: [root@localhost ~]#
2）删除组
[root@localhost ~]# ansible websers -m group -a 'name=xxx state=absent'
192.168.0.218 | SUCCESS => {
"changed": true,
"name": "xxx",
"state": "absent"
}
192.168.0.99 | SUCCESS => {
"changed": true,
"name": "xxx",
"state": "absent"
}
[root@localhost ~]# ansible websers -m shell -a 'getent group xxx'
192.168.0.218 | FAILED | rc=2 >>
non-zero return code 192.168.0.99 | FAILED | rc=2 >>
non-zero return code [root@localhost ~]#
7、setup：此模块主要功能收集远程主机上的信息
模块帮助：
[root@localhost ~]# ansible-doc -s setup
- name: Gathers facts about remote hosts
setup:
fact_path: # path used for local ansible facts (*.fact) - files in this dir will be run (if executable) and their results
be added to ansible_local facts if a file is not executable it is read. Check
notes for Windows options. (from 2.1 on) File/results format can be json or
ini-format
filter: # if supplied, only return facts that match this shell-style (fnmatch) wildcard.
gather_subset: # if supplied, restrict the additional facts collected to the given subset. Possible values: all, min,
hardware, network, virtual, ohai, and facter Can specify a list of values to
specify a larger subset. Values can also be used with an initial `!' to
specify that that specific subset should not be collected. For instance:
!hardware, !network, !virtual, !ohai, !facter. If !all is specified then only
the min subset is collected. To avoid collecting even the min subset, specify
!all and !min subsets. To collect only specific facts, use !all, !min, and
specify the particular fact subsets. Use the filter parameter if you do not
want to display some collected facts.
gather_timeout: # Set the default timeout in seconds for individual fact gathering
[root@localhost ~]#
常用参数说明：
filter：指定我们过滤的信息变量
[root@localhost ~]# ansible *99 -m setup -a 'filter=ansible_all_ipv4_addresses'
192.168.0.99 | SUCCESS => {
"ansible_facts": {
"ansible_all_ipv4_addresses": [
"172.17.0.1",
"192.168.0.99"
]
},
"changed": false
}
[root@localhost ~]#
说明：setup模块默认不跟参数，它会显示很多信息，不利于我们查看想要的信息，所以一般都会跟上参数过滤自己想要查看的参数。以上命令表示查看远端主机上的所有ipv4的ip地址。
