Efficient operation and maintenance 1:saltstack installation configuration

I. Introduction of Saltstack

Saltstack is a new basic setup management approach that is easy to deploy, works in minutes, scales well, and easily manages tens of thousands of servers, fast enough, and second-level communication between servers. By deploying the Saltstack environment, we can execute batch commands on thousands of servers, configure centralized management according to different business features, distribute files , collect server data , Operating system base and software package management , Saltstack is the operation and maintenance personnel to improve work efficiency, standardize business configuration and operations of the weapon.

second, the experimental environment

1. Version

System version: CentOS 6.4 64bitPython version: Native version 2.6Salt version: 2014.7.1

2. Experimental architecture

salt-master:192.168.1.225 soft:salt-mastersalt-minion01:192.168.1.226 soft:salt-minionsalt-minion02:192.168.1.228 soft:salt-minion

Third, start to install salt

This installation Saltstack uses Yum installation, so third-party yum sources (Epel and rpmforge) are required

1. Install Epel source

# RPM-UVH http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

3. Install dependent packages

# yum-y Install PYTHON-JINJA2

4. Install Saltstack Package

Server Installation Salt-master Package # Yum-y Install Salt-master remaining managed end installed Salt-minion Package # yum-y Install Salt-minion

Iv. start configuration of Saltstack

1. Modify the Minion configuration file

# vim/etc/salt/minionmaster:192.168.0.106id:saltstack_minion_01#master IP Address, note that there must be a space after the colon, otherwise syntax error # Client identification Used to display the Salt-key in the Public key list, otherwise the IP address is displayed; must have a space after the colon

1. Server Start salt-master Service #/etc/init.d/salt-master Start2, controlled end start salt-minion Service #/etc/init.d/salt-minion start

Vi. Use of Saltstack

1. View the list of public keys on the master side

[Email protected] ~]# salt-key-laccepted keys:saltstack_minion_01 saltstack_minion_02 unaccepte D keys:rejected Keys:

2. Test the connectivity of the host, the usage of the hard disk, the network interface address

# salt ' * ' test.ping# salt ' * ' disk.usage# salt ' * ' network.interfaces

3. Execute command Test remotely

• The CMD module contains the output of the shell on the controlled side, such as Cmd.run and Cmd.run_all

# salt ' * ' cmd.run date# salt ' * ' cmd.run uptime# salt ' * ' Cmd.run ' df-h ' # salt ' * ' cmd.run ' ls-l/etc '

# salt ' * ' pkg.install vim

Vii.. Salt-key parameters

1. Salt-key Common options

• -L,--list-all

#列出所有的公钥

• -A ACCEPT,--accept=accept

#接受指定的公钥
