## salt介绍 ##

SaltStack是一个服务器基础架构集中化管理平台，具备配置管理、远程执行、监控等功能，基于Python语言实现，结合轻量级消息队列（ZeroMQ）与Python第三方模块（Pyzmq、PyCrypto、Pyjinjia2、python-msgpack和PyYAML等）构建。

SaltStack 采用 C/S模式，server端就是salt的master，client端就是minion，minion与master之间通过ZeroMQ消息队列通信。

master监听4505和4506端口，4505对应的是ZMQ的PUB system，用来发送消息，4506对应的是REP system是来接受消息的。

#### 命令执行步骤 ####

具体步骤如下

*  Salt stack的Master与Minion之间通过ZeroMq进行消息传递，使用了ZeroMq的发布-订阅模式，连接方式包括tcp，ipc
 *  salt命令，将cmd.run ls命令从salt.client.LocalClient.cmd\_cli发布到master，获取一个Jodid，根据jobid获取命令执行结果。
 *  master接收到命令后，将要执行的命令发送给客户端minion。
 *  minion从消息总线上接收到要处理的命令，交给minion.\_handle\_aes处理
 *  minion.\_handle\_aes发起一个本地线程调用cmdmod执行ls命令。线程执行完ls后，调用minion.\_return\_pub方法，将执行结果通过消息总线返回给master
 *  master接收到客户端返回的结果，调用master.\_handle\_aes方法，将结果写的文件中
 *  salt.client.LocalClient.cmd\_cli通过轮询获取Job执行结果，将结果输出到终端。

## saltstack安装 ##

#### 测试环境 ####

*  CentOS6.5
 *  master：172.20.22.46 (主机名：hadoop1) \# 之前配置Spark改的名字
 *  slave：172.20.22.159 (主机名：hadoop2)

#### 分为以下几步 ####

##### 关闭selinux #####

/etc/selinux/config，把SELINUX=enforcing改为SELINUX=disabled

##### master安装salt-minion, salt-master #####

Google

##### slave安装salt-minion #####

Google

##### 配置salt-master #####

参考

#指定master，冒号后有一个空格
    master: 192.168.2.22
    user: root
    
    #-------以下为可选--------------
    # salt运行的用户，影响到salt的执行权限
    user: root
    #s alt的运行线程，开的线程越多一般处理的速度越快，但一般不要超过CPU的个数
    worker_threads: 10
    # master的管理端口
    publish_port : 4505
    # master跟minion的通讯端口，用于文件服务，认证，接受返回结果等
    ret_port : 4506
    # 如果这个master运行的salt-syndic连接到了一个更高层级的master,那么这个参数需要配置成连接到的这个高层级master的监听端口
    syndic_master_port : 4506
    # 指定pid文件位置
    pidfile: /var/run/salt-master.pid
    # saltstack 可以控制的文件系统的开始位置
    root_dir: /
    # 日志文件地址
    log_file: /var/log/salt_master.log
    # 分组设置
    nodegroups:
      group_all: '*'
    # salt state执行时候的根目录
    file_roots:
      base:
        - /srv/salt/
    # 设置pillar 的根目录
    pillar_roots:
      base:
        - /srv/pillar

本文主要改动

file_roots:
      base:
        - /srv/salt/base
      dev:
        - /srv/salt/dev
      test:
        - /srv/salt/test
      prod:
        - /srv/salt/prod

##### 配置salt-minion #####

参考

#指定master，冒号后有一个空格
    master: 192.168.2.22
    id: minion-01
    user: root
    
    #-------以下为可选--------------
    # minion的识别ID，可以是IP，域名，或是可以通过DNS解析的字符串
    id: 192.168.0.100
    # salt运行的用户权限
    user: root
    # master的识别ID，可以是IP，域名，或是可以通过DNS解析的字符串
    master : 192.168.0.100
    # master通讯端口
    master_port: 4506
    # 备份模式，minion是本地备份，当进行文件管理时的文件备份模式
    backup_mode: minion
    # 执行salt-call时候的输出方式
    output: nested 
    # minion等待master接受认证的时间
    acceptance_wait_time: 10
    # 失败重连次数，0表示无限次，非零会不断尝试到设置值后停止尝试
    acceptance_wait_time_max: 0
    # 重新认证延迟时间，可以避免因为master的key改变导致minion需要重新认证的syn风暴
    random_reauth_delay: 60
    # 日志文件位置
    log_file: /var/logs/salt_minion.log
    # 文件路径基本位置
    file_roots:
      base:
        - /etc/salt/minion/file
    # pillar基本位置
    pillar_roots:
      base:
        - /data/salt/minion/pillar

本文主要改动

master : 172.20.22.46
    grains:
      roles:
        - nginx
      env:
        - test
      myname:
        - yzd

##### 启动/重启salt #####

sudo service salt-master start/restart

sudo service salt-minion start/restart

##### master认证minion的key #####

Google

##### 检查安装是否完成 #####

[root@hadoop1 Desktop]# salt-run manage.status
    down:
    up:
        - hadoop1
        - hadoop2
    
    [root@hadoop1 Desktop]# salt '*' grains.item os myname
    hadoop1:
        ----------
        myname:
        os:
            CentOS
    hadoop2:
        ----------
        myname: # 自定义的grains
            - yzd
        os:
            CentOS

##### 其它 #####

关于grains/pillar/state等可以查阅文档

## 部署WordPress ##

### 环境要求 ###

> 摘自官网  
> We recommend servers running version 7.2 or greater of PHP and MySQL version 5.6 OR MariaDB version 10.0 or greater.  
> We also recommend either Apache or Nginx as the most robust options for running WordPress, but neither is required.

### 安装Apache和Php ###

#### 流程 ####

*  安装apache和php依赖
 *  将主机的apache和php配置文件覆盖从机文件
 *  运行apache服务

web/ap.sls：

lamp-install:
      pkg.installed:
        - pkgs:
          - httpd
          - php
          - php-pdo
          - php-mysql
          - php-gd
    
    apache-config:
      file.managed:
        - name: /etc/httpd/conf/httpd.conf #服务实际使用的文件路径
        - source: salt://web/files/httpd.conf #salt的源文件用于分发到minion上面 路径是base目录下面的web 这里也支持http和ftp方式
        - user: root
        - group: root
        - mode: 644
        - require:
          - pkg: lamp-install
    
    php-config:
      file.managed:
        - name: /etc/php.ini
        - source: salt://web/files/php.ini
        - user: root
        - group: root
        - mode: 644
    
    #使用watch在apache配置文件发送变化时，重新加载apache配置
    lamp-service:
      service.running:
        - name: httpd
        - enable: True
        - reload: True  #如果不加reload 默认会重启服务
        - watch: #增加
          - file: apache-config #监控上面的apache-config ID 所以说 一个ID在一个状态只能出现一次
    
    apache-conf:
      file.recurse:
        - name: /etc/httpd/conf.d
        - source: salt://web/files/apache-conf.d

运行结果：

### 安装Mysql5.6 ###

**注意：CentOS6 yum自带的Mysql版本是5.1，达不到wordpress的最低版本要求。这里我们使用源码安装mysql5.6。步骤比较多，坑也很多。**

#### 流程 ####

*  传输mysql源码包至从机
 *  解压源码包
 *  安装编译所需依赖
 *  源码安装mysql
 *  将主机my.cnf覆盖从机文件
 *  运行conf.sh，使用scripts/mysql\_install\_db建立数据库
 *  运行mysqllns.sh创建所需要的软连接
 *  将主机mysqld覆盖从机文件
 *  运行mysqld

    # chkconfig: 2345 10 50
    # description: mysqld
    basedir=/usr/local/mysql/
    datadir=/usr/local/mysql/data/

注意：  
需要添加下面两行来保证chkconfig设置成功

#!/bin/sh
    # chkconfig: 2345 10 50

#### 运行结果 ####

由于首次运行编译返回日志过长，为了美观的结果，运行了两次，所以软连接脚本显示失败（文件已存在）

                      To start mysqld at boot time you have to copy
                      support-files/mysql.server to the right place for your system
    
                      PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
                      To do so, start the server, then issue the following commands:
    
                        /usr/local/mysql//bin/mysqladmin -u root password 'new-password'
                        /usr/local/mysql//bin/mysqladmin -u root -h 192.168.253.62 password 'new-password'
    
                      Alternatively you can run:
    
                        /usr/local/mysql//bin/mysql_secure_installation
    
                      which will also give you the option of removing the test
                      databases and anonymous user created by default.  This is
                      strongly recommended for production servers.
    
                      See the manual for more instructions.
    
                      You can start the MySQL daemon with:
    
                        cd . ; /usr/local/mysql//bin/mysqld_safe &
    
                      You can test the MySQL daemon with mysql-test-run.pl
    
                        cd mysql-test ; perl mysql-test-run.pl

## 总结 ##

成功通过master的saltstack为slave安装lamp环境，并将openstack部署成功。

### 遇到的问题整理 ###

#### 无法运行state.sls ####

报错the function “state.highstate” is running as PID xxxx  
kill掉slave的进程

#### php admin不显示网页 ####

重启apache  
sudo service httpd restart

#### MySQL启动报：\[ERROR\] The server quit without updating PID file ####

[https://blog.csdn.net/ydyang1126/article/details/72473828][https_blog.csdn.net_ydyang1126_article_details_72473828]

#### cmd.run的顺序控制 ####

[https://www.jianshu.com/p/624b9cf51c64][https_www.jianshu.com_p_624b9cf51c64]

查看顺序  
salt ‘hadoop2’ state.show\_sls wordpress.wp-install  
order越小越早执行，-1是最后

#### Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2) ####

[http://aiezu.com/article/mysql\_cant\_connect\_through\_socket.html][http_aiezu.com_article_mysql_cant_connect_through_socket.html]

#### service mysqld does not support chkconfig ####

[https://www.cnblogs.com/niocai/archive/2012/07/12/2587780.html][https_www.cnblogs.com_niocai_archive_2012_07_12_2587780.html]

#### unless命令 ####

[http://blog.51cto.com/732233048/1677843][http_blog.51cto.com_732233048_1677843]

unless：用于检查的命令，仅当`unless`选项指向的命令返回false时才执行name指向的命令

若minion端不存在/tmp/nginx-1.4.5.tar.gz这个文件，才会执行这个file模块
