准备工作
环境： CentOS6.5 64位
MongoDB 3.0.1 64位
一、启动mongod服务
? [root@localhost data]# /usr/local/mongodb3.0.1/bin/mongod --port 40144 --dbpath=/data/mongodb3.0.1/data/ --logpath=/data/mongodb3.0.1/log/mongodb.log --directoryperdb --maxConns 100 --logappend --replSet repl/192.168.66.89:50144 --fork
[root@localhost data]# /usr/local/mongodb3.0.1/bin/mongod --port 50144 --dbpath=/data/mongodb3.0.1/db_50144/ --logpath=/data/mongodb3.0.1/db_50144/mongodb.log --directoryperdb --maxConns 100 --logappend --replSet repl/192.168.66.89:40144 --fork
[root@localhost data]# /usr/local/mongodb3.0.1/bin/mongod --port 60144 --dbpath=/data/mongodb3.0.1/db_60144/ --logpath=/data/mongodb3.0.1/db_60144/mongodb.log --directoryperdb --maxConns 100 --logappend --replSet repl/192.168.66.89:40144 --fork
?
参数：
--oplogSize 日志操作文件的大（默认磁盘剩余空间的5%）
--dbpath 数据文件路径
--logpath 日志文件路径
--port 端口号，默认是27017
--replSet 复制集的名字，一个replica sets中的每个节点的这个参数都要用一个复制集名字，这里是test.
--replSet test/ 这个后面跟的是其他standard节点的ip和端口
--maxConns 最大连接数
--fork 后台运行
--logappend 日志文件循环使用，如果日志文件已满，那么新日志覆盖最久日志。
任选一个节点登录mongodb数据库 [root@localhost data]# /usr/local/mongodb3.0.1/bin/mongo --port 40144
MongoDB shell version: 3.0.1
connecting to: 127.0.0.1:40144/test
