超详细saltstack安装部署及应用

1.环境准备

准备两台虚拟机


主机名
ip
role

linux-node1
10.0.0.7
master

linux-node2
10.0.0.8
minion

在节点1上安装 master 和 minion

[[email protected] ~]yum install salt-master salt-minion -y

在节点2上安装 minion

[[email protected] ~]yum install  salt-minion -y

分别设置开机自启动

[[email protected] ~]chkconfig  salt-master on

[[email protected] ~]chkconfig  --add salt-master

[[email protected] ~]chkconfig  salt-minion on

[[email protected] ~]chkconfig  --add salt-minion

[[email protected] ~]chkconfig  salt-minion on

[[email protected] ~]chkconfig  --add salt-minion

指定master

vim /etc/salt/minion

master: 10.0.0.7

授权节点1和节点2

slat-key -a linux*

2.测试

测试 ping 节点1 和节点2

salt ‘*‘ test.ping

执行 cmd.run  执行bash查看负载命令

salt ‘*‘ cmd.run ‘uptime‘

设置sls文件的路径

[[email protected] ~]mkdir -p /srv/salt/base

[[email protected] ~]mkdir -p /srv/salt/test

[[email protected] ~]mkdir -p /srv/salt/prod

vim /etc/salt/master

file_roots:

base:

- /srv/salt/base

test:

- /srv/salt/test

prod:

- /srv/salt/prod

重启master

/etc/init.d/salt-master restart

编写YMAL安装Apache 并设置启动文件

cd /srv/salt

vim apache.sls

apache-install:

pkg.installed:

- names:

- httpd

- httpd-devel

apache-service:

service.running:

- name: httpd

- enable: True

- reload: True

执行状态文件

salt ‘*‘ state.sls apache

编写高级状态文件

vim top.sls

base:

‘linux-node2‘:

- apache

slat ‘*‘ state.highstate   #执行高级状态 top.sls

3.数据系统之 Grains

salt ‘linux-node1‘ grains.items  #查询所有键值

salt ‘linux-node1‘ grains.get fqdn #查询单个主机值

显示所有 节点1 eth0的ip

[[email protected] ~]# salt ‘linux-node1‘ grains.get ip_interfaces:eth0

linux-node1:

- 10.0.0.7

- fe80::20c:29ff:fe9d:57e8

#根据系统名称匹配执行cmd.run命令

[[email protected] ~]# salt -G os:CentOS cmd.run ‘w‘  #-G 代表使用grains匹配

linux-node2:

03:47:49 up  9:58,  2 users,  load average: 0.00, 0.00, 0.00

USER     TTY      FROM              [email protected]   IDLE   JCPU   PCPU WHAT

root     pts/1    10.0.0.1         17:50    1:31m  0.14s  0.14s -bash

root     pts/0    10.0.0.1         03:37    5:40   0.00s  0.00s -bash

linux-node1:

03:47:49 up  1:35,  2 users,  load average: 0.00, 0.00, 0.00

USER     TTY      FROM              [email protected]   IDLE   JCPU   PCPU WHAT

root     pts/0    10.0.0.1         02:13    1:01m  0.08s  0.01s vim top.sls

root     pts/1    10.0.0.1         03:37    0.00s  0.52s  0.34s /usr/bin/python

vim /etc/salt/grains

web: nginx

salt -G web:nginx cmd.run ‘w‘

4.数据系统之 Pillar

设置pillar文件的路径

vim /etc/salt/master

pillar_roots:

base:

- /srv/pillar

mkdir /srv/pillar #创建默认pillar目录

/etc/init.d/salt-master restart

vim /srv/pillar/apache.sls  #使用jinja模板语言

{%if grains[‘os‘] == ‘CentOS‘ %}

apache: httpd

{% elif grains[‘os‘] == ‘Debian‘ %}

apache: apche2

{% endif %}

vim /srv/pillar/top.sls

base:

‘*‘:

- apache

[[email protected] ~]# salt ‘*‘ pillar.items

linux-node2:

----------

apache:

httpd

linux-node1:

----------

apache:

httpd

配置完 pillar需要刷新 生效

[[email protected] ~]salt ‘*‘ saltutil.refresh_pillar

[[email protected] ~]#  salt -I ‘apache:httpd‘ test.ping

linux-node2:

True

linux-node1:

True

http://docs.saltstack.cn/topics/index.html    #slatstack中文网站

slatstack 之远程执行

targeting

moudles

returners

基于对模块的访问控制

[[email protected] ~]vim /etc/salt/master

client_acl:

oldboy:                      #oldboy用户下只能使用test.ping network的所有方法

- test.ping

- network.*

user01:

- linux-node1*:

- test.ping

权限设置

chmod 755 /var/cache/salt /var/cache/salt/master /var/cache/salt/master/jobs /var/run/salt /var/run/salt/master

[[email protected] ~]/etc/ini.d/salt-master restart

[[email protected] ~]# su - oldboy

[[email protected] ~]$ salt ‘*‘ cmd.run ‘df -h‘

[WARNING ] Failed to open log file, do you have permission to write to /var/log/salt/master?

Failed to authenticate! This is most likely because this user is not permitted to execute commands, but there is a small possibility that a disk error occurred (check disk/inode usage).

创建表结构 3个表：

CREATE DATABASE `salt`

DEFAULT CHARACTER SET utf8

DEFAULT COLLATE utf8_general_ci;

USE `salt`;

CREATE TABLE `jids` (

`jid` varchar(255) NOT NULL,

`load` mediumtext NOT NULL,

UNIQUE KEY `jid` (`jid`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE INDEX jid ON jids(jid) USING BTREE;

CREATE TABLE `salt_returns` (

`fun` varchar(50) NOT NULL,

`jid` varchar(255) NOT NULL,

`return` mediumtext NOT NULL,

`id` varchar(255) NOT NULL,

`success` varchar(10) NOT NULL,

`full_ret` mediumtext NOT NULL,

`alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

KEY `id` (`id`),

KEY `jid` (`jid`),

KEY `fun` (`fun`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `salt_events` (

`id` BIGINT NOT NULL AUTO_INCREMENT,

`tag` varchar(255) NOT NULL,

`data` mediumtext NOT NULL,

`alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

`master_id` varchar(255) NOT NULL,

PRIMARY KEY (`id`),

KEY `tag` (`tag`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

授权salt用户

grant all on salt.* to [email protected]‘10.0.0.0/255.255.255.0 identified by ‘salt‘;

yum install -y MySQL-python     #同步数据依赖 MySQL-python包

vim /etc/salt/master

底部添加

master_job_cache: mysql   #加上这一句 执行的命令自动保存到数据库不用加--return mysql

mysql.host: ‘10.0.0.7‘

mysql.user: ‘salt‘

mysql.pass: ‘salt‘

mysql.db: ‘salt‘

mysql.port: 3306

/etc/init.d/salt-master restart

测试命令执行结果是否同步到数据库

[[email protected] ~]# salt ‘*‘ cmd.run ‘ls‘ --return mysql

编译安装所需的依赖包

yum install gcc gcc-c++ glibc autoconf make openssl openssl-devel

5.web集群架构自动化部署

5.1安装haproxy

cd /usr/local/src && tar zxf haproxy-1.7.9.tar.gz && cd haproxy-1.7.9 && make TARGET=linux26 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy

cd /usr/local/src/haproxy-1.7.9/examples/

vim haproxy.init

BIN=/usr/local/haproxy/sbin/$BASENAME  更改启动脚本的默认路径

cp haproxy-init /srv/salt/prod/haproxy/files/

编写YMAL脚本

mkdir /srv/salt/prod/pkg            #源码安装依赖包sls

mkdir /srv/salt/prod/haproxy        #haproxy安装 sls

mkdir /srv/salt/prod/haproxy/files    #存放haproxy源码压缩包

haproxy自动化编译安装。

cd /srv/salt/prod/pkg

编译安装所需依赖包的自动化安装

vim pkg-init.sls

pkg-init:

pkg.installed:                 #pkg的installed

- names:

- gcc

- gcc-c++

saltstack安装部署以及简单实用

一,saltstack简介:     SaltStack是一种新的基础设施管理方法开发软件,简单易部署,可伸缩的足以管理成千上万的服务器,和足够快的速度控制,与他们交流,以毫秒为单位. SaltStack提供了一个动态基础设施通信总线用于编排,远程执行.配置管理等等.SaltStack基于python开发,项目于2011年启动,年增长速度较快,五年期 固定基础设施编制和配置管理的开源项目.SaltStack社区致力于保持盐项目集中.友好.健康.开放. (网上摘抄的,说白了saltStack就是一

saltstack安装部署与入门使用

一.saltstack简介 SaltStack 一种基于 C/S 架构的服务器基础架构集中化管理平台,管理端称为 Master,客户端称为 Minion.SaltStack 具备配置管理.远程执行.监控等功能,一般可以理解为是简化版的 Puppet 和加强版的 Func.SaltStack 本身是基于 Python 语言开发实现,结合了轻量级的消息队列软件 ZeroMQ 与 Python 第三方模块(Pyzmq.PyCrypto.Pyjinjia2.python-msgpack 和 PyYAML

自动化运维工具---SaltStack安装部署及简单案例

SaltStack原理 SaltStack由Master(服务端)和Minion(客户端)组成,Master和Minion之间通过ZeroMQ(消息队列)进行通讯,Master和Minion分别监听4505与4506端口,4505为master与minion认证通信端口,4506为master用来发送或者接受minion的命令执行返回信息. 当客户端启动后,会主动链接master端注册,然后一直保持该TCP连接,而master通过这条TCP连接对客户端进行控制,如果连接断开,master将对客户
