- name: M a n a g e u s e r a c c o u n t s
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 exce
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 lik
remove # When used with `state=absent', behavior is as with `userdel --remove'.
shell # Optionally set the user's shell.
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.
[root@node1 ansible]#
示例：
创建一个用户testuser uid=1000
[root@node1 ansible]# ansible testservers -m user -a 'name=testuser uid=1000 shell=/bin/bash home=/opt/testuser state=present'

Homepage: http://www.greenwoodsoftware.com/less - name: A d d o r r e m o v e g r o u p s 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. [root@node1 ansible]#
示例：
创建一个用户组
[root@node1 ansible]# ansible testservers -m group -a 'name=testgroup gid=1100 state=present'
192.168.100.131 | success >> {
"changed": true,

"changed": true,
"gid": 1100,
"name": "testgroup",

综合示例：
在主机上创建一个testgroup组，然后创建一个testuser，并将其加入testgroup组
[root@node1 ansible]# ansible testservers -m group -a 'name=testgroup gid=1100 state=present' [root@node1 ansible]# ansible testservers -m user -a 'name=testuser uid=1000 shell=/bin/bash home=/opt/testuser group=testgroup state=present' [root@node1 ansible]# ansible testservers -m command -a 'id testuser' 192.168.100.132 | success | rc=0 >> uid=1000(testuser) gid=1100(testgroup) groups=1100(testgroup) 192.168.100.131 | success | rc=0 >> uid=1000(testuser) gid=1100(testgroup) groups=1100(testgroup)
