proxy_env
ansible_host
参数详解
proxy_env
在某些受到“互联网封锁”的地区,有些软件的下载会受到影响。
例如,从中国大陆访问PostgreSQL的官方源,下载速度可能只有几KB每秒。但如果使用了合适的HTTP代理,则可以达到几MB每秒。
因此,如果您有代理服务器,请通过proxy_env
进行配置,样例如下:
proxy_env: # global proxy env when downloading packages
http_proxy: 'http://username:password@proxy.address.com'
https_proxy: 'http://username:password@proxy.address.com'
all_proxy: 'http://username:password@proxy.address.com'
no_proxy: "localhost,127.0.0.1,10.0.0.0/8,192.168.0.0/16,*.pigsty,*.aliyun.com"
ansible_host
如果您的环境使用了跳板机,或者进行了某些定制化修改,无法通过简单的ssh <ip>
方式访问,那么可以考虑使用Ansible的连接参数。ansible_host
是ansiblel连接参数中最典型的一个。
ansible_host
The name of the host to connect to, if different from the alias you wish to give to it.
ansible_port
The ssh port number, if not 22
ansible_user
The default ssh user name to use.
ansible_ssh_pass
The ssh password to use (never store this variable in plain text; always use a vault. See Variables and Vaults)
ansible_ssh_private_key_file
Private key file used by ssh. Useful if using multiple keys and you don’t want to use SSH agent.
ansible_ssh_common_args
This setting is always appended to the default command line for sftp, scp, and ssh. Useful to configure a
ProxyCommand
for a certain host (or group).ansible_sftp_extra_args
This setting is always appended to the default sftp command line.
ansible_scp_extra_args
This setting is always appended to the default scp command line.
ansible_ssh_extra_args
This setting is always appended to the default ssh command line.
ansible_ssh_pipelining
Determines whether or not to use SSH pipelining. This can override the
pipelining
setting inansible.cfg
.
最简单的用法是将ssh alias
配置为ansible_host
,只要您可以通过ssh <name>
的方式访问目标机器,那么将ansible_host
配置为<name>
即可。注意这些变量都是实例级别的变量。
