    一、configsvr 配置 （10.3.20.14:27017、10.3.20.51:27017、10.3.20.54:27017）

    配置过程：以 10.3.20.14:27017 为例，其他两台类似

    1、安装配置 mongodb

    # wget https://mirrors.aliyun.com/mongodb/yum/redhat/6Server/mongodb-org/3.6/x86_64/RPMS/mongodb-org-3.6.6-1.el6.x86_64.rpm
# wget https://mirrors.aliyun.com/mongodb/yum/redhat/6Server/mongodb-org/3.6/x86_64/RPMS/mongodb-org-mongos-3.6.6-1.el6.x86_64.rpm
# wget https://mirrors.aliyun.com/mongodb/yum/redhat/6Server/mongodb-org/3.6/x86_64/RPMS/mongodb-org-server-3.6.6-1.el6.x86_64.rpm
# wget https://mirrors.aliyun.com/mongodb/yum/redhat/6Server/mongodb-org/3.6/x86_64/RPMS/mongodb-org-shell-3.6.6-1.el6.x86_64.rpm
# wget https://mirrors.aliyun.com/mongodb/yum/redhat/6Server/mongodb-org/3.6/x86_64/RPMS/mongodb-org-tools-3.6.6-1.el6.x86_64.rpm

# ls
mongodb-org-3.6.6-1.el6.x86_64.rpm         mongodb-org-server-3.6.6-1.el6.x86_64.rpm  mongodb-org-tools-3.6.6-1.el6.x86_64.rpm
mongodb-org-mongos-3.6.6-1.el6.x86_64.rpm  mongodb-org-shell-3.6.6-1.el6.x86_64.rpm

# rpm -ivh *

# egrep -v "^$|^#" /etc/mongod.conf 
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
storage:
  dbPath: /var/lib/mongo
  journal:

  fork: true  # fork and run in background

net:
  port: 27017
  bindIp: 127.0.0.1,10.3.20.14  # Listen to local interface only, comment to listen on all interfaces.

    2、启动 mongodb

    # /etc/init.d/mongod start
Starting mongod:                                           [  OK  ]
# ps -ef|grep mongod
mongod     4074      1 32 18:19 ?        00:00:01 /usr/bin/mongod -f /etc/mongod.conf
root       4098   1421  0 18:20 pts/0    00:00:00 grep mongod
# netstat -nltup|grep 4074
tcp        0      0 10.3.20.14:27017            0.0.0.0:*                   LISTEN      4074/mongod         
tcp        0      0 127.0.0.1:27017             0.0.0.0:*                   LISTEN      4074/mongod

    3、mongodb 认证配置

    # mongo
MongoDB shell version v3.6.6
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.6
Server has startup warnings: 
2018-07-16T18:28:34.139+0800 I STORAGE  [initandlisten]

// 配置要认证才能登录（加上 security: authorization: 'enabled' 配置）
# egrep -v "^$|^#" /etc/mongod.conf 
systemLog:

  logAppend: true
  path: /var/log/mongodb/mongod.log
storage:

processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
net:
  port: 27017
  bindIp: 127.0.0.1,10.3.20.14  # Listen to local interface only, comment to listen on all interfaces.
security:
  authorization: 'enabled'


# /etc/init.d/mongod restart

// 访问方式 1
# mongo -u root -p 123456 --authenticationDatabase admin
> show databases;
admin   0.000GB
config  0.000GB
local   0.000GB

    4、配置 configsvr 复制集

    配置集群 keyfile（3台机器用同一个key）

    # openssl rand -base64 756 > mongo.key
# mv mongo.key /var/lib/mongo/
# chown mongod:mongod /var/lib/mongo/mongo.key
# chmod 600 /var/lib/mongo/mongo.key

# egrep -v "^#|^$" /etc/mongod.conf
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
net:
  port: 27017
  bindIp: 127.0.0.1,10.3.20.14  # Listen to local interface only, comment to listen on all interfaces.
security:
  authorization: 'enabled'
  keyFile: /var/lib/mongo/mongo.key
replication:
  oplogSizeMB: 500
  replSetName: repdata
sharding:
  clusterRole: configsvr

# /etc/init.d/mongod restart

// 这步只需要在 10.3.20.14 操作，建立 configsvr 的复制集
# mongo -u root -p 123456 10.3.20.14/admin
>  cfg={ _id:"repdata", configsvr: true, members:[ {_id:0,host:'10.3.20.14:27017',priority:2}, {_id:1,host:'10.3.20.51:27017',priority:1}, {_id:2,host:'10.3.20.54:27017',priority:1}] }
> rs.initiate(cfg)

    二、sharding01 配置 （10.3.20.102:27017、10.3.20.105:27017、10.3.20.132:27017）

    1、安装 mongodb，参考 （一）的 1、2、3步骤

    2、集群之间的 key，使用（一）的 4 步骤的 mongo.key

    3、sharding01 复制集配置

    # egrep -v "^$|^#" /etc/mongod.conf 
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
net:
  port: 27017
  bindIp: 127.0.0.1,10.3.20.102  # Listen to local interface only, comment to listen on all interfaces.
security:
  authorization: 'enabled'
  keyFile: /var/lib/mongo/mongo.key
replication:
  replSetName: sharding01
sharding:
  clusterRole: shardsvr

# /etc/init.d/mongod restart

// 这步只需要在 10.3.20.102 操作，建立 sharding01 的复制集
# mongo -u root -p 123456 10.3.20.102/admin
MongoDB shell version v3.6.6
connecting to: mongodb://10.3.20.102:27017/admin

    四、mongos 配置 （10.3.20.14:27018、10.3.20.51:27018、10.3.20.54:27018）

    1、安装 mongodb，参考 （一）的 1、2、3步骤

    2、集群之间的 key，使用（一）的 4 步骤的 mongo.key

    3、mongos 配置

    # egrep -v "^$|^#" /etc/mongos.conf 
systemLog:
  destination: file
  path: /var/log/mongodb/mongos.log
  logAppend: true
processManagement:
  fork: true

  bindIp: 127.0.0.1,10.3.20.14
  port: 27018
security:
  keyFile: /var/lib/mongo/mongo.key
sharding:
  configDB: repdata/10.3.20.14:27017,10.3.20.51:27017,10.3.20.54:27017

# mongos -f /etc/mongos.conf

{

    "ok" : 1,
    "$clusterTime" : {
        "clusterTime" : Timestamp(1531904052, 8),

            "hash" : BinData(0,"3jHS/99+ya4pASBp7Pm0JNOBMX8="),
            "keyId" : NumberLong("6579439166424088595")
        }
    },
    "operationTime" : Timestamp(1531904052, 8)
}
mongos> sh.addShard("sharding02/10.3.20.141:27017,10.3.20.142:27017,10.3.20.143:27017")
{
    "shardAdded" : "sharding02",
    "ok" : 1,
    "$clusterTime" : {
        "clusterTime" : Timestamp(1531904104, 4),
        "signature" : {
            "hash" : BinData(0,"XiVKlJFOagVCUpd1C/coLrjG2JY="),
            "keyId" : NumberLong("6579439166424088595")
        }
    },
    "operationTime" : Timestamp(1531904104, 2)
}
mongos> sh.status()
--- Sharding Status --- 
  sharding version: {
    "_id" : 1,

        Currently running:  no
        Failed balancer rounds in last 5 attempts:  0

    五、sharding 集群测试

    # mongo --host 10.3.20.14 --port 27018
MongoDB shell version v3.6.6
connecting to: mongodb://10.3.20.14:27018/
