SaltStack Char02 组件
2.1Target : 管理的对象
Master上，通过采用不同的Target去管理不同的Minion
Salt命令的Target Options 参数信息
1 正则匹配
#salt -E 'TestS*' test.ping
2 列表匹配
#salt -L TestSlave_1,TestSlave1_Audio test.ping
#salt -L ‘TestSlave_1,TestSlave1_Audio’ test.ping
3 Grains匹配
#salt -G 'os:Ubuntu' test.ping
4 组匹配
#salt -N groups test.ping
5 复合匹配
#salt -C 'G@os:MacOS or L@Minion1' test.ping
6 Pillar值匹配
7 CIDR匹配
2.2 管理对象的属性
Grains
2.2.1 通过Minion配置文件定义Grains ???
2.2.2 通过Grains模块定义Grains
2.3 数据管理中心
Pillar在SaltStack中主要的作用就是存储和定义配置管理中需要的一些数据,比如软件版本号、用户名密码等信息,它的定
2.4 针对管理对象的操作
1 查看所有的module列表
salt '*' sys.list_modules
2 查看制定module的所有function
# saltTestSlave1_Audiosys.list_functions cmd
TestSlave1_Audio:
- cmd.exec_code
- cmd.exec_code_all
- cmd.has_exec
- cmd.retcode
- cmd.run
- cmd.run_all
- cmd.run_chroot
- cmd.run_stderr
- cmd.run_stdout
- cmd.script
- cmd.script_retcode
- cmd.shell
- cmd.shells
- cmd.tty
- cmd.which
- cmd.which_bin
2.3 查看指定module用法
# salt TestSlave1_Audio sys.doc cmd.run'cmd.run:'
Execute the passed command and return the output as a string
Note that ``env`` represents the environment variables for the command, and
should be formatted as a dict, or a YAML string which resolves to a dict.
Warning:
This function does not process commands through a shell
unless the python_shell flag is set to True. This means that any
shell-specific functionality such as 'echo' or the use of pipes,
redirection or &&, should either be migrated to cmd.shell or
have the python_shell=True flag set here.
The use of python_shell=True means that the shell will accept _any_ input
including potentially malicious commands such as 'good_command;rm -rf /'.
Be absolutely certain that you have sanitized your input prior to using
python_shell=True
CLI Example:
salt '*' cmd.run "ls -l | awk '/foo/{print \$2}'"
The template arg can be set to 'jinja' or another supported template
engine to render the command arguments before execution.
For example:
salt '*' cmd.run template=jinja "ls -l /tmp/{{grains.id}} | awk '/foo/{print \$2}'"
Specify an>
salt '*' cmd.run "Get-ChildItem C:\ " shell='powershell'
A string of standard input can be specified for the command to be run using
the ``stdin`` parameter. This can be useful in cases where sensitive
information must be read from standard input.:
salt '*' cmd.run "grep f" stdin='one\ntwo\nthree\nfour\nfive\n'
If an equal sign (``=``) appears in an argument to a Salt command it is
interpreted as a keyword argument in the format ``key=val``. That
processing can be bypassed in order to pass an equal sign through to the
remote shell command by manually specifying the kwarg:
salt '*' cmd.run cmd='sed -e s/=/:/g'
2.5 配置管理
States 是 SaltStack中的配置语言
2.5.1 查看所有的states列表
# salt TestSlave1_Audio sys.list_state_modules | head -10
TestSlave1_Audio:
- acl
- alias
-> - apt
- archive
- artifactory
- blockdev
- buildout
- cloud
2.5.2 查看制定states中的所有function
2.5.3 查看制定states用法
# salt TestSlave1_Audio sys.list_state_modules.apt | head -10
TestSlave1_Audio:
'sys.list_state_modules.apt' is not available.
root@Ly-banya:~# salt TestSlave1_Audio sys.state_doc file | head -10
TestSlave1_Audio:
----------
file:
Operations on regular files, special files, directories, and symlinks
=====================================================================
Salt States can aggressively manipulate files on a system. There are a number
of ways in which files can be managed.
2.5.4 查看制定states指定function用法
2.5.5 从一个简单的实例去了解states
# cat foo.conf
SaltStack Books
root@Ly:/srv/salt# cat one.sls
/tmp/foo.conf:
file.managed:
- source: salt://foo.conf
- user: root
- group: root
- mode: 644
- backup: minion
:/srv/salt# salt TestSlave1_Audio state.sls one
TestSlave1_Audio:
----------
ID: /tmp/foo.conf
Function: file.managed
Result: True
Comment: File /tmp/foo.conf is in the correct state

2.6 执行结果处理
Return 组件可以理解为SaltStack系统对执行Minion返回后的数据进行存储或者返回给其他程序，它支持多种存储，比如MySQL , MonogDB 、Redis
通过Return 我们可以对SaltStack的每次操作进行记录，以后可以用来日志审计
2.6.1 查看所有Return 列表
# salt TestSlave1_Audio sys.list_returners
TestSlave1_Audio:
- carbon
- couchdb
- etcd
- hipchat
- local
- local_cache
- multi_returner
- slack
- smtp
- sqlite3
- syslog
