TokuMX 初体验

TokuMX2.0号称比MongoDB快50倍，同时完全兼容MongoDB 2.4的驱动。今天先在自己的开发机器上体验一下。

首先下载，由于我是Ubuntu 14.10，目前还没有支持package安装方式，所以下载了压缩包，解压后放在/opt/tokumx-2.0.0-linux-x86_64

之后，参考官方文档，添加链接：

$ ln -snf /opt/tokumx-2.0.0-linux-x86_64/bin/* /usr/local/bin	
$ which mongod
/usr/local/bin/mongod
$ readlink /usr/local/bin/mongod
/opt/tokumx-2.0.0-linux-x86_64/bin/mongod

然后处理几个细节，就可以启动了, 我仅仅是体验，并没有立即做成系统服务，所以只在dean用户下启动

mkdir -p /data/db
chmod -R dean:dean /data/db

关闭内核的一个功能，才能启动：

echo never > /sys/kernel/mm/transparent_hugepage/enabled

好，现在运行mongod命令：

$ mongod
mongod --help for help and startup options

然后在另一个terminal中运行mongo, 连接正常，可以当成一个mongodb来使用了。

现在编译mongodb c++驱动，参考我的另一篇博客：

MongoDB 4.6.1 c++ driver 编译

然后使用C++程序访问TokuMX，连接和创建数据库是正常的。

可以通过监控站点查看TokuMX的状态。
