Mongodb 复制集Replica Set搭建与测试
环境准备：
服务器：
192.168.0.33 CentOS release 5.5 (Final)
192.168.0.99 CentOS release 5.5 (Final)
Mongodb版本：
mongodb-linux-x86_64-rhel55-3.0.5.tgz
Replica Set
其实简单来说就是集群当中包含了多份数据，保证主节点挂掉了，备节点能继续提供数据服务，提供的前提就是数据需要和主节点一致
Replica Set使用的是n个mongod节点，构建具备自动的容错功能(auto-failover),自动恢复的(auto-recovery)的高可用方案。
默认设置下，主节点提供所有增删查改服务，备节点不提供任何服务。但是可以通过设置使备节点提供查询服务，这样就可以减少主节点的压力
Mongodb Replica Set环境搭建：
1.规划：
两台机器上构建一个集群分片：
规划对应的端口号：
192.168.0.33 Shard Server 1：28010
192.168.0.99 Shard Server 2：28011
192.168.0.99 Shard Server 3：28012
2.在服务器上创建目录：
192.168.0.33：
mkdir -p /appl/mongodb/data/r0
mkdir -p /appl/mongodb/data/log
mkdir -p /appl/mongodb/data/key
echo "this is rs1 super secret key" > /appl/mongodb/data/key/r0
chmod 600 /appl/mongodb/data/key/r*
192.168.0.99：
mkdir -p /appl/mongodb/data/r1
mkdir -p /appl/mongodb/data/r2
mkdir -p /data/log
mkdir -p /appl/mongodb/data/key
echo "this is rs1 super secret key" > /appl/mongodb/data/key/r1
echo "this is rs1 super secret key" > /appl/mongodb/data/key/r2
chmod 600 /appl/mongodb/data/key/r*
上传mongdb安装文件到两台服务器的/appl/mongodb和/appl/mongodb目录解压
tar -zxvf mongodb-linux-x86_64-rhel55-3.0.5.tgz
然后把解压的bin目录下的所有文件移动/appl/mongodb和/appl/mongodb目录下
3.启动Shard Server实例
启动Shard Server实例1（192.168.0.33）
/appl/mongodb/mongod --replSet rs1 --keyFile /appl/mongodb/data/key/r0 --fork --port 28010 --dbpath /appl/mongodb/data/r0 --logpath=/appl/mongodb/data/log/r0.log --logappend
启动Shard Server实例2（192.168.0.99）
/appl/mongodb/mongod --replSet rs1 --keyFile /appl/mongodb/data/key/r1 --fork --port 28011 --dbpath /appl/mongodb/data/r1 --logpath=/appl/mongodb/data/log/r1.log –logappend
启动Shard Server实例3（192.168.0.99）
/appl/mongodb/mongod --replSet rs1 --keyFile /appl/mongodb/data/key/r2 --fork --port 28012 --dbpath /appl/mongodb/data/r2 --logpath=/appl/mongodb/data/log/r2.log --logappend
4. 配置及初始化 Replica Sets创建数据目录:
config_rs1 = {_id: 'rs1', members: [
{_id: 0, host: '192.168.0.33:28010', priority:1},
{_id: 1, host: '192.168.0.99:28011'},
{_id: 2, host: '192.168.0.99:28012'}]}
rs.initiate(config_rs1);
[root@tts mongodb]# ./mongo --port 28010
MongoDB shell version: 3.0.5
connecting to: 127.0.0.1:28010/test
