Ansible提供了user模块，这样的话在其他服务器上可以使用user模块创建用户了。。
用法
[root@ansible ~]# ansible-doc -s user
less 436
.........................
- name: Manage user accounts
action: 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 this comma-delimited list of groups. When set to the empty string (‘groups=‘),
the user is removed from all groups except the primary group.
home # Optionally set the user‘s home directory.
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= # 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‘.
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.需要特别说明的是，password后面指定的密码不能是明文，后面这一串密码会被直接传送到被管理主机的/etc/shadow文件中，而登陆的时候输入的密码会被hash加密以后再去与/etc/shadow中存放的密码去做对比，会出现不一致的现象。所以需要先将密码字符串进行加密处理：openssl passwd -salt -1 “123456”，然后将得到的字符串放到password中即可。
示例:
在web组机器上创建一个test用户，密码为123456，家目录为/home/test下，uid位678，comment注释为this is a ansible test user，shell为/bin/sh等等
[root@ansible ~]# openssl passwd -salt -1 "123456"
-1DhUWqz2JZqc[root@ansible ~]# ansible webser -m user -a "name=test password=1DhUWqz2JZqc home=/home/test uid=678 comment=‘this is a ansible test user‘ shell=/bin/sh"
webser | SUCCESS => {
"changed": true,
"comment": "this is a ansible test user",
"createhome": true,
"group": 678,
"home": "/home/test",
"name": "haha",
"password": "NOT_LOGGING_PASSWORD",
"shell": "/bin/sh",
"state": "present",
"stderr": "useradd: warning: the home directory already exists.\nNot copying any file from skel directory into it.\n",
"system": false,
"uid": 678
}验证创建的用户
[root@ansible ~]# ansible webser -m raw -a ‘tail /etc/passwd|grep test‘
webser | SUCCESS | rc=0 >>

- name: Add or remove groups
action: group
gid # Optional `GID‘ to set for the group.
name= # 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.创建一个组为g1，gid为666 state状态在远程主机上要么创建(present)要么删除absent，system是否为系统用，有些选择都是可选的
[root@ansible ~]# ansible webser -m group -a ‘name=g1 gid=666 state=present system=yes‘
web | SUCCESS => {
"changed": true,
"gid": 666,
"name": "g1",
"state": "present",
"system": true
}验证下创建的组g1
[root@ansible ~]# ansible web -m raw -a ‘tail /etc/group|grep g1‘
web | SUCCESS | rc=0 >>
