MongoDB學習整理之Replica Sets安裝

準備：       
        服務器       端口             數據目錄                                        日志                                    復制集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、創建數據文件、日志路徑目錄及復制集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、啟動3個mongodb實例模擬3個節點服務器：

/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環境
[mongodb@ www.linuxidc.com mongo]$ /app/mongo/mongodb/bin/mongo -port 28010      //連接

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