分片集群-规划

10个实例：38017-38026
(1)configserver:38018-38020
3台构成的复制集（1主两从，不支持arbiter）38018-38020（复制集名字configsvr）
(2)shard节点：
sh1:38021-23   (1主两从，其中一个节点为arbiter,复制集名字sh1)
sh2:38024-26   (1主两从，其中一个节点为arbiter,复制集名字sh2)
(3):mongos:
38017

Shard节点配置过程 目录创建：

mkdir -p /mongodb/38021/{conf,log,data}
mkdir -p /mongodb/38022/{conf,log,data}
mkdir -p /mongodb/38023/{conf,log,data}
mkdir -p /mongodb/38024/{conf,log,data}
mkdir -p /mongodb/38025/{conf,log,data}
mkdir -p /mongodb/38026/{conf,log,data}

修改配置文件： 第一组复制集搭建：21-23 （1主1从 1Ard）

启动所有节点，并搭建复制集

mongod -f  /mongodb/38021/conf/mongodb.conf 
mongod -f  /mongodb/38022/conf/mongodb.conf 
mongod -f  /mongodb/38023/conf/mongodb.conf 
mongod -f  /mongodb/38024/conf/mongodb.conf 
mongod -f  /mongodb/38025/conf/mongodb.conf 
mongod -f  /mongodb/38026/conf/mongodb.conf  
ps -ef |grep mongod
