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

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 ...
- 注意，启动mongos客户端命令是
