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: 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

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'}
1
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
