​​官方安装​​

以下centos或redhat安装

1. 配置yum

$ cat <>/etc/yum.repos.d/my.repo
[epel]
name=epel
baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
enable=1
gpgcheck=0
eof

2. 安装

$ yum -y install ansible

3. 帮助

$ ansible-doc -h
Usage: ansible-doc [options] [module...]
Options:
 -a, --all Show documentation for all modules
 -h, --help show this help message and exit
 -l, --list List available modules
 -M MODULE_PATH, --module-path=MODULE_PATH
 specify path(s) to module library (default=None)
 -s, --snippet Show playbook snippet for specified module(s)
 -v, --verbose verbose mode (-vvv for more, -vvvv to enable
 connection debugging)
 --version show program's version number and exit

其中"-l"选项⽤于列出ansible的模块，通常结合grep来筛选。例如找出和yum相关的可⽤模块。

$ ansible-doc -l | grep yum
yum Manages packages with the `yum' package manager
yum_repository Add or remove YUM repositories

再使⽤"-s"选项可以获取指定模块的使⽤帮助。例如，获取yum模块的使⽤语法。

ansible-doc -s yum
- name: Manages packages with the `yum' package manager
 action: yum
 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 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  against.
 name= # Package name, or package specifier with version, like `name-1.0'.
 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.
 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 update_cache # Force yum to check if cache is out of date and redownload if needed.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'.
