MongoDB 5 安装&副本集搭建&集群搭建

单节点安装

需要一个数据目录地址，一个日志文件地址，配置文件

## 数据目录地址
--dapath=
## 日志文件
--logpath=
## 配置文件
--config=***.conf

下载

https://fastdl.mongodb.org/osx/mongodb-macos-x86_64-5.0.27.tgz

启动命令

/data/dba/yanhao/application/mongodb/bin/mongod --config=/data/dba/yanhao/application/mongodbData/single/mongodb1.conf

客户端登录命令

## --host指定ip，--port指定端口
/data/dba/yanhao/application/mongodb/bin/mongo --host 127.0.0.1 --port 27030

## 创建用户，关闭mongodb
## 配置文件打开认证
## 重启mongodb

主从搭建

创建另一个节点，需要data目录，log文件，配置文件
启动

rs.add("ip:port");
## 进入从节点执行,表明允许从从节点上读取数据
rs.secondaryOk();

开启认证

注意：密钥的读写权限不能太大，400即可，否则启动失败

## 生成密钥文件
openssl rand -base64 666 > mongodb.key

集群搭建

建立联系

mongos中用sh.addShard添加分片信息
mongos的配置文件中指定了config文件的数据库地址

启动顺序

config服务器必须在mongos服务器启动之前启动


config服务器启动
config服务器初始化
shard服务器
mongos服务器

分片操作

对数据库启用分片
```
sh.enableSharding("dbName")
```

对集合启用分片

sh.shardCollection("dbName.collectionName",{"shardKeyFiled":"hashed"})

启动

登入分片客户端，将分片内节点添加到replSet内，rs.add("ip:port")
登入mongos客户端，添加分片，sh.addShard("shardName/ip:port,ip:port,ip:port")
- 注意，启动mongos客户端命令是mongos -f ...mongodb.conf，不是mongod -f ...
