MongoDB学习整理之Replica Sets安装


准备：       
        服务器       端口             数据目录                                        日志                                    复制集key文件
        Server1  28010   /app/mongo/mongodb/data/sets/r0    /app/mongo/mongodb/data/sets/log/r0.log    /app/mongo/mongodb/data/sets/key/r0
        Server2  28011   /app/mongo/mongodb/data/sets/r1    /app/mongo/mongodb/data/sets/log/r2.log    /app/mongo/mongodb/data/sets/key/r1
        Server3  28012   /app/mongo/mongodb/data/sets/r2    /app/mongo/mongodb/data/sets/log/r3.log    /app/mongo/mongodb/data/sets/key/r2

1、创建数据文件、日志路径目录及复制集key文件
        mkdir -p /app/mongo/mongodb/data/sets/r0
        mkdir -p /app/mongo/mongodb/data/sets/r1
        mkdir -p /app/mongo/mongodb/data/sets/r2
        mkdir -p /app/mongo/mongodb/data/sets/key/
        mkdir -p /app/mongo/mongodb/data/sets/log/

        echo "test sets" > /app/mongo/mongodb/data/sets/key/r0
        echo "test sets" > /app/mongo/mongodb/data/sets/key/r1
        echo "test sets" > /app/mongo/mongodb/data/sets/key/r2

        chmod 600 /app/mongo/mongodb/data/sets/key/r*

2、启动3个mongodb实例模拟3个节点服务器：

/app/mongo/mongodb/bin/mongod --replSet rs1 --keyFile /app/mongo/mongodb/data/sets/key/r0 --port 28010 --dbpath=/app/mongo/mongodb/data/sets/r0 --logpath=/app/mongo/mongodb/data/sets/log/r0.log --logappend --fork

/app/mongo/mongodb/bin/mongod --replSet rs1 --keyFile /app/mongo/mongodb/data/sets/key/r1 --port 28011 --dbpath=/app/mongo/mongodb/data/sets/r1 --logpath=/app/mongo/mongodb/data/sets/log/r2.log --logappend --fork

/app/mongo/mongodb/bin/mongod --replSet rs1 --keyFile /app/mongo/mongodb/data/sets/key/r2 --port 28012 --dbpath=/app/mongo/mongodb/data/sets/r2 --logpath=/app/mongo/mongodb/data/sets/log/r3.log --logappend --fork

3、初始化Replica Sets环境
[mongodb@ www.bkjia.com mongo]$ /app/mongo/mongodb/bin/mongo -port 28010      //连接

>config_rs={_id:'rs1',members:[{_id:0,host:'localhost:28010'},{_id:1,host:'localhost:28011'},{_id:2,host:'localhost:28012'}]}
>rs.initiate(config_rs);

4、查看复制集状态，分析复制集的各项运行指标,如图所示：

OK，成功了。
