Tarantool安装及基本使用

Tarantool安装及基本使用

1.前言

Features

• A drop-in replacement for Lua 5.1, based on LuaJIT 2.1;
  simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script
• Lua packages for non-blocking I/O, fibers and HTTP
• MessagePack data format and MessagePack based client-server protocol
• a built-in database with two data engines: 100% in-memory with optional persistence and a 2-level disk-based B-tree, to use with large data sets
• secondary key and index iterators support
• asynchronous master-master replication
• authentication and access contro
• 上述是引用官方的介绍，总的来说Tarantool是一个高性能的key/value存储服务器
• http://tarantool.org/ 官网地址

下面开始Tarantool之旅

2.环境准备

• CentOS 6.5 虚机一台

3.开始安装

• 添加yum源在 /etc/yum.repos.d/ 下创建文件 tarantool.repo并写入以下内容

  [tarantool]
  name=CentOS-$releasever - Tarantool
  baseurl=http://tarantool.org/dist/master/centos/$releasever/os/$basearch/
  enabled=1
  gpgcheck=0

• 执行yum安装命令

  sudo yum install tarantool.

  待命令执行完毕Tarantool就安装完毕了。

4.启动运行Tarantool

• 创建数据库工作目录如：

  mkdir ~/swq_tarantool_box
  cd ~/swq_tarantool_box

• 启动Tarantool

  /usr/bin/tarantool
  /usr/bin/tarantool: version 1.6.7-463-gfc14541
  type 'help' for interactive help

  到目前为止我们已近启动起来了tarantool，tarantool与redis或者其他可能不一样，他是没有配置文件的，现在我们只是进入到了tarantool的交互环境而已，下一步我们将启动数据库

• 配置Tarantool

  box.cfg{listen=3301,log_level=5, logger='tarantool.txt'}

  执行上述命令后我们已经启动起来了Tarantool，3301为监听端口，日志等级为5info级别，输出文件为当前目录下载的tarantool.txt。下面我们看下日志文件的内容。
  注：日志文件每次是增量append的。

  可从上述日志看到tarantool从下述文件进行了数据恢复
  注：类似redis的持久文件恢复，但是这些只是Tarantool的操作变动日志，并不是磁盘的持久化数据

  ./00000000000000000000.snap
  ./00000000000000000112.xlog
  ./00000000000000500112.xlog
  ./00000000000001000112.xlog
  ./00000000000001110148.xlog
  ./00000000000001610148.xlog
  ./00000000000002110148.xlog
  

  上述文件保存当前目录下tarantool的所有数据信息，如space，索引，每个space的记录等等，这些文件是我测试遗留下的。这里稍微扩展下：一个Tarantool可对应多个space，每个space有两种数据存储引擎可选，分别是memtx和sophia其实就是内存与磁盘，然后每个space下对应了具体的kv值了。使用过Redis的肯定知道space有点像redis的db概念，又对应了关系数据库的表概念，总之上手理解很快。具体相关信息大家可以查看官方文档。

5.Tarantool基本命令使用

• 创建空间

  s = box.schema.space.create('swq_test')
  注：s为引用别名
  

• 创建主键

  i = s:create_index('primary', {type = 'hash', parts = {1, 'NUM'}})
  

• insert

  s:insert{123} s:insert{456,123123} s:insert{789,123123,'hello tarantool'} 

• select

  s:select{}
  

• delete

  s:delete{123}
  

  具体命令使用参看：http://tarantool.org/doc/book/box/box_space.html
