MongoDB3.0集群配置文件自动生成器

项目Github地址：
https://github.com/jockchou/mongodb-conf-generator
文件说明：
    -- cfg.conf.template
    -- mongod.conf.template
    -- mongos.conf.template
cfg.conf.template ： 集群配制服务器配制文件模板
mongod.conf.template： mongod进程配制文件模板
mongos.conf.template： mongos路由进程配制文件模板
generator.php ： 自动生成配制文件的PHP脚本
脚本使用方法：
在你的Linux服务器上创建一个新目录，我这里创建的目录是/data/mongo
mkdir -p /data/mongo
复制本项目录下上述四个文件到/data/mongo目录中，执行php generator.php。执行前先确保机器上已经安装PHP。
