目录
前言
一、自动化安装keepalived模块
实验环境：
server1 服务端 saltstack-master 172.24.28.1
server2 客户端 saltstack-minion 172.25.28.2
server3 客户端 saltstack-minion 172.25.28.3
apache下面的lib.sls中的生效
测试：
keepalived+pillar
salt/keepaliveed/lib.sls写pillar中条件：会推倒minion端
pillar不会推到minion
1.配置vim /srv/salt/keepalived/init.sls
[root@server1 ~]# cd /srv/salt
[root@server1 salt]# ls
apache _grains _modules nginx test.sls top.sls
[root@server1 salt]# mkdir keepalived
[root@server1 salt]# cd keepalived/
[root@server1 keepalived]# ls
[root@server1 keepalived]# vim init.sls
2.配置pillar vim /srv/pillar/top.sls和vim /srv/pillar/kp.sls
3.配置 vim /srv/salt/top.sls
4.复制server2的/etc/keepalived/keepalived.conf的文件到server1
5.配置vim /srv/salt/keepalived/keepalived.conf
6.server1（master）服务端推送至minion端
7.查看真机访问172.25.28.100
二、Job管理
• master在下发指令任务时,会附带上产生的jid。
• minion在接收到指令开始执行时,会在本地的/var/cache/salt/minion/proc
目录下产生该jid命名的文件,用于在执行过程中master查看当前任务的执行
情况。
• 指令执行完毕将结果传送给master后,删除该临时文件。
• Job Cache
- Job缓存默认保存24小时：
- vim /etc/salt/master中keep_jobs: 24##默认值
- master端Job缓存目录：
- /var/cache/salt/master/jobs
安装数据库, 开启mariadb服务，安全认证
把Job存储到数据库
1.方式一
###vim test.sql
CREATE DATABASE `salt`
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;
USE `salt`;
--
-- Table structure for table `jids`
--
DROP TABLE IF EXISTS `jids`;
CREATE TABLE `jids` (
`jid` varchar(255) NOT NULL,
`load` mediumtext NOT NULL,
UNIQUE KEY `jid` (`jid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
--
-- Table structure for table `salt_returns`
--
DROP TABLE IF EXISTS `salt_returns`;
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;
--
-- Table structure for table `salt_events`
--
DROP TABLE IF EXISTS `salt_events`;
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;
test.sql 导入数据库
查看一下数据库的表和库，在server1上添加用户认证
修改server2的minion的配置文件，重启服务测试
测试
2.方式二：
直接从master端传到数据库
修改server1的master的配置文件，重启服务测试
测试：
三、salt-ssh
• salt-ssh可以独立运行的,不需要minion端。
• salt-ssh 用的是sshpass进行密码交互的。
• 以串行模式工作,性能下降。
假定server3 minion无法安，使用salt-ssh方式
实验步骤：
server1安装salt-ssh
vim /etc/salt/roster
测试：
四、salt-syndic
syndic其实就是个代理，隔离master与minion。 Syndic必须要运行在master上，再连接到另一个topmaster上。
Topmaster下发的状态需要通过syndic来传递给下级master，minion传递给master的数据也是由syndic传递给topmaster。
topmaster并不知道有多少个minion。
syndic与topmaster的file_roots和pillar_roots的目录要保持一致。
四台虚拟机：
server1 服务端 master 172.24.28.1
server2 客户端 minion 172.25.28.2
server3 客户端 minion 172.25.28.3
server4 客户端 top-master 172.25.28.4
server4配置：
server1配置：
在server4上获得密钥
测试：
server4 作为 顶级master 执行任务会派发给下级 master（server1）执行
五、salt-api
1.server1下载api
2.server1生成key和crt
生成证书
3.激活rest_cherrypy
4.创建用户认证
重启服务
6.salt-api使用：获取认证token
7.推送任务：测试
推送任务：df -h
8.结合python脚本直接推送任务
