  • Saltstack_使用指南08_远程执行-返回程序

    1. 主机规划

    salt 版本
    1 [root@salt100 ~]# salt --version
2 salt 2018.3.3 (Oxygen)
3 [root@salt100 ~]# salt-minion --version
4 salt-minion 2018.3.3 (Oxygen)
    Returners文档
    https://docs.saltstack.com/en/latest/ref/returners/index.html

    Returner Modules文档

    https://docs.saltstack.com/en/latest/ref/returners/all/index.html#all-salt-returners

    注意事项

    修改了master或者minion的配置文件，那么必须重启对应的服务。

     

    2. 数据库配置

    2.1. 数据库安装

    根据规划在 salt100 部署mariadb 数据库

    1 # 数据库安装
2 yum install -y mariadb mariadb-server    
3 # 启动数据库
4 systemctl start mariadb.service   # 如果有必要可以设置为开机自启动
5 # 在「其他」机器安装，用于测试远程是否可以连接
6 yum install -y mariadb

    2.2. 字符集设置

    配置文件也要修改

     1 [root@salt100 ~]# mysql
 2 Welcome to the MariaDB monitor.  Commands end with ; or g.

 4          DEFAULT COLLATE utf8_general_ci;

11 | salt     | CREATE DATABASE `salt` /*!40100 DEFAULT CHARACTER SET utf8 */ |
12 +----------+---------------------------------------------------------------+
13 1 row in set (0.00 sec)
14 
15 # 创建用户并授权
16 MariaDB [(none)]> grant all on salt.* to salt@'%' identified by 'salt';  # 用于远程访问
17 Query OK, 0 rows affected (0.00 sec)
18

26 +------+---------+-------------------------------------------+
27 | user | host    | password                                  |
28 +------+---------+-------------------------------------------+
29 | salt | %       | *36F75ABC6D500DFA6E905046FD8BE5E115812DD0 |
30 | salt | salt100 | *36F75ABC6D500DFA6E905046FD8BE5E115812DD0 |
31 +------+---------+-------------------------------------------+
32 2 rows in set (0.00 sec)

    本地或者远程登录测试

    1 mysql -hsalt100 -usalt -psalt
2 # 或者
3 mysql -h172.16.1.100 -usalt -psalt

    2.4. 创建表

    相关文档

    https://docs.saltstack.com/en/latest/ref/returners/all/salt.returners.mysql.html#module-salt.returners.mysql
     1 use salt;
 2 
 3 --
 4 -- Table structure for table `jids`
 5 --
 6 DROP TABLE IF EXISTS `jids`;
 7 CREATE TABLE `jids` (
 8   `jid` varchar(255) NOT NULL,
 9   `load` mediumtext NOT NULL,
10   UNIQUE KEY `jid` (`jid`)
11 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
12 
13 --
14 -- Table structure for table `salt_returns`
15 --
16 DROP TABLE IF EXISTS `salt_returns`;
17 CREATE TABLE `salt_returns` (
18   `fun` varchar(50) NOT NULL,
19   `jid` varchar(255) NOT NULL,
20   `return` mediumtext NOT NULL,
21   `id` varchar(255) NOT NULL,
22   `success` varchar(10) NOT NULL,
23   `full_ret` mediumtext NOT NULL,
24   `alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
25   KEY `id` (`id`),
26   KEY `jid` (`jid`),
27   KEY `fun` (`fun`)
28 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
29 
30 --
31 -- Table structure for table `salt_events`
32 --
33 DROP TABLE IF EXISTS `salt_events`;
34 CREATE TABLE `salt_events` (
35 `id` BIGINT NOT NULL AUTO_INCREMENT,
36 `tag` varchar(255) NOT NULL,
37 `data` mediumtext NOT NULL,
38 `alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
39 `master_id` varchar(255) NOT NULL,
40 PRIMARY KEY (`id`),
41 KEY `tag` (`tag`)
42 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

    3. 安装依赖包

    1 salt '*' state.single pkg.installed name=MySQL-python    
2 或者
3 salt '*' cmd.run 'yum install -y MySQL-python'

    4. minion返回结果到MySQL数据库

    由 minion 端直接返回到 MySQL 数据库，不需要经过 master 端。

    相关文档

    https://docs.saltstack.com/en/latest/topics/jobs/external_cache.html

    4.1. minion端存储架构

    4.2. 方式一：所有Minion端都添加设置

    1 [root@salt03 ~]# vim /etc/salt/minion 
2 …………
3 mysql.host: 'salt100'
4 mysql.user: 'salt'
5 mysql.pass: 'salt'
6 mysql.db: 'salt'
7 mysql.port: 3306
8 
9 [root@salt03 ~]# systemctl restart salt-minion.service  # 修改了配置，需要重启 minion

    4.3. 方式二：在master端添加设置

     1 [root@salt100 ~]# vim /etc/salt/master 
 2 …………
 3 ext_job_cache: mysql
 4 mysql.host: 'salt100'
 5 mysql.user: 'salt'
 6 mysql.pass: 'salt'
 7 mysql.db: 'salt'
 8 mysql.port: 3306
 9 
10 [root@salt100 ~]# systemctl restart salt-master.service   # 修改了配置，需要重启 master

    4.4. 测试执行

     1 # 说明： 带了 --return mysql ，适合上面的方式一，在minion端配置
 2 # 如果没有带  --return mysql ，适合上面的方式二，在master端配置
 3 [root@salt100 ~]# salt '*' test.ping --return mysql  
 4 salt03:
 5     True
 6 salt01:
 7     True
 8 salt02:
 9     True
10 salt100:
11     True
12 [root@salt100 ~]# salt 'salt0*' cmd.run 'df -h' --return mysql

    4.5. 数据库表信息

    5. master返回结果到MySQL数据库

    数据从minion端返回到master之后，再由master写入MySQL

    相关文档

    https://docs.saltstack.com/en/latest/topics/jobs/external_cache.html

    5.1. master端存储架构

    5.2. master端添加如下配置

     1 [root@salt100 ~]# vim /etc/salt/master 
 2 …………
 3 master_job_cache: mysql
 4 mysql.host: 'salt100'
 5 mysql.user: 'salt'
 6 mysql.pass: 'salt'
 7 mysql.db: 'salt'
 8 mysql.port: 3306
 9 
10 [root@salt100 ~]# systemctl restart salt-master.service   # 修改了配置，需要重启 master

    5.3. 测试执行

    1 [root@salt100 ~]# salt '*' grains.items
2 [root@salt100 ~]# salt '*' cmd.run 'w'

    5.4. 数据库表信息
