mongo 副本集+分片 配置

服务器规划如下：

副本集名称|服务器IP	192.168.56.111	192.168.56.112	192.168.56.113
shard1	3201	3201	3201
shard2	3202	3202	3202
shred3	3203	3203	3203
mongos	3200	3200
conf1	3888	3888	3888

192.168.56.111,192.168.56.112,192.168.56.113 新建目录
mkdir -p /data/mongodb/shard1/db
mkdir -p /data/mongodb/shard1/log
mkdir -p /data/mongodb/shard2/db
mkdir -p /data/mongodb/shard2/log
mkdir -p /data/mongodb/shard3/db
mkdir -p /data/mongodb/shard3/log
mkdir -p /data/mongodb/mongos/db
mkdir -p /data/mongodb/mongos/log
mkdir -p /data/mongodb/conf1/db
mkdir -p /data/mongodb/conf1/log

　　第一部分:配置服务器conf1  配置如下:

conf.yml配置文件:

systemLog:
    destination: file
    logAppend: true
    path: /data/mongodb/conf1/log/mongo.log

# Where and how to store data.
storage:
    dbPath: /data/mongodb/conf1/db
    journal:
        enabled: true
# how the process runs
processManagement:
    fork: true
    pidFilePath: /data/mongodb/configsvr.pid

# network interfaces
net:
    port: 3888

#operationProfiling:
replication:
    replSetName: config        

sharding:
    clusterRole: configsvr

启动config server ，启动3台

#启动命名
/usr/local/mongodb/bin/mongod -f conf.yml 

#登录任意一台配置服务器，初始化配置副本集
config={_id : 'config',members : [{_id : 1, host : '192.168.56.111:3888'},{_id : 2, host : '192.168.56.112:3888'},{_id : 3, host : '192.168.56.113:3888'}]} ;
rs.initiate(config);

第二部分:分片+副本集

shard1配置文件，shard2,shard3配置文件参考shard1配置文件:

systemLog:
    destination: file
    logAppend: true
    path: /data/mongodb/shard1/log/mongo.log

# Where and how to store data.
storage:
    dbPath: /data/mongodb/shard1/db
    journal:
        enabled: true
    wiredTiger:
        engineConfig:
            cacheSizeGB: 1

# how the process runs
processManagement:
    fork: true
    pidFilePath: /data/mongodb/shard1.pid

# network interfaces
net:
    port: 3201

#operationProfiling:
replication:
    replSetName: shard1        

sharding:
    clusterRole: shardsvr

启动shard1 副本集:  shard2,shard3启动参考shard1

/usr/local/mongodb/bin/mongod -f shard1.yml 

登录任意一台配置服务器，初始化shard1,shard2,shard3副本集
config={_id : 'shard1',members : [{_id : 1, host : '192.168.56.111:3201'},{_id : 2, host : '192.168.56.112:3201'},{_id : 3, host : '192.168.56.113:3201'}]};
rs.initiate(config);

config={_id : 'shard2',members : [{_id : 1, host : '192.168.56.111:3202'},{_id : 2, host : '192.168.56.112:3202'},{_id : 3, host : '192.168.56.113:3202'}]};
rs.initiate(config);

config={_id : 'shard3',members : [{_id : 1, host : '192.168.56.111:3203'},{_id : 2, host : '192.168.56.112:3203'},{_id : 3, host : '192.168.56.113:3203'}]};
rs.initiate(config);

第三部分:配置路由服务器

mongos配置文件:

systemLog:
    destination: file
    logAppend: true
    path: /data/mongodb/mongos/log/mongo.log

processManagement:
    fork: true

# network interfaces
net:
    port: 3200

sharding:
    configDB: config/192.168.56.111:3888,192.168.56.112:3888,192.168.56.113:3888
#config配置服务器副本集名称
192.168.56.112:3888

启动路由服务:

/usr/local/mongodb/bin/mongos -f mongos.yml

#登录路由服务器添加分片:
mongo 192.168.56.111:3200
use  admin;
sh.addShard("shard1/192.168.56.111:3201,192.168.56.112:3201,192.168.56.113:3201");
sh.addShard("shard2/192.168.56.111:3202,192.168.56.112:3202,192.168.56.113:3202");
sh.addShard("shard3/192.168.56.111:3203,192.168.56.112:3203,192.168.56.113:3203");
sh.status();
