这里有新鲜出炉的Mysql教程，程序狗速度看过来！

Mysql关系型数据库管理系统

MySQL是一个开放源码的小型关联式数据库管理系统，开发者为瑞典MySQL AB公司。MySQL被广泛地应用在Internet上的中小型网站中。由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，许多中小型网站为了降低网站总体拥有成本而选择了MySQL作为网站数据库。

本文主要介绍了如何使用playbook安装mysql,需要的朋友可以参考下

上次介绍了如何使用ansible playbook安装zabbix客户端这次介绍一下如何使用playbook安装mysql。

下面是安装mysql的信息：


mysql_basedir: /data/mysql/basedir     源码目录
mysql_datadir: /data/mysql/datadir     数据目录
mysql_user: mysql          mysql用户
mysql_database_user: root        数据库用户
mysql_passwd: 'E4yR3WnoluSFTCBAI'      数据库密码
mysql_port: 3306          mysql监听端口
mysql_sock: /data/mysql/datadir/mysql.sock   mysql的sock
mysql_charset: utf8         mysql字符集
mysql_collation: utf8_general_ci      mysql排序方式
mysql_version: Percona-Server-5.5.21-rel25.1.tar.gz mysql版本

下面是安装mysql的playbook结构


10:24:06 # tree mysql_*
mysql_delete
├── files
├── handlers
├── meta
│ └── main.yml
├── tasks
│ ├── delete.yml
│ └── main.yml
├── templates
└── vars
 └── main.yml
mysql_install
├── files
│ └── mysql.tar.gz
├── handlers
├── meta
│ └── main.yml
├── tasks
│ ├── copy.yml
│ ├── delete.yml
│ ├── install.yml
│ └── main.yml
├── templates
│ ├── install_mysql.sh
│ ├── my.cnf
│ ├── mysqld
│ └── mysql_security.sh
└── vars
 └── main.yml

12 directories, 15 files

playbook的mysql安装的是


10:32:06 # cat mysql_install.yml 
---
- hosts: "{{host}}"
 remote_user: "{{user}}"
 gather_facts: True
 roles:
 - common
 - mysql_install

playbook的mysql协助的是


10:32:44 # cat mysql_delete.yml 
---
- hosts: "{{host}}"
 remote_user: "{{user}}"
 gather_facts: True
 roles:
 - mysql_delete

由于在上篇安装zabbix客户端已经介绍了结构，所以现在不介绍了。


10:26:00 # time ansible-playbook mysql_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem

2、安装后测试

登陆192.168.240.17的测试机查看mysql安装情况

可以看到已经按照我的要求安装完成，下面在进行删除测试。

3、删除

可以看到都删除完成。

如果大家想使用我的例子，可以从百度云的地址下载（文件大于50M，没办法放到附件或者51下载中心）地址是http://pan.baidu.com/s/1mgG8jY4，然后放到/etc/ansible目录里，下面是压缩包里的内容
