MongoDB的基本功能
特点
- 使用BSON存储数据
- 支持相对丰富的查询操作
- 支持索引
- 副本集
- 分片
- 无模式
- 部署简单方便
启动mongodb
MongoDB/bin/mongod --dbpath MongoDB/data/db
mongodb服务器上守护进程
创建一个conf配置文件,然后运行命令:
./bin/mongod --config mydb.conf
复制代码
# mongodb.conf
# Where to store the data.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
bind_ip = 127.0.0.1
#port = 27017
# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true
# Enables periodic logging of CPU utilization and I/O wait
#cpu = true
# Turn on/off security. Off is currently the default
#noauth = true
#auth = true
# Verbose logging output.
#verbose = true
# Inspect all client data for validity on receipt (useful for
# developing drivers)
#objcheck = true
# Enable db quota management
#quota = true
# Set oplogging level where n is
# 0=off (default)
# 1=W
# 2=R
# 3=both
# 7=W+some reads
#oplog = 0
# Diagnostic/debugging option
#nocursors = true
# Ignore query hints
#nohints = true
# Disable the HTTP interface (Defaults to localhost:27018).
#nohttpinterface = true
# Turns off server-side scripting. This will result in greatly limited
# functionality
#noscripting = true
# Turns off table scans. Any query that would do a table scan fails.
#notablescan = true
# Disable data file preallocation.
#noprealloc = true
# Specify .ns file size for new databases.
# nssize = <size>
# Accout token for Mongo monitoring server.
#mms-token = <token>
# Server name for Mongo monitoring server.
#mms-name = <server-name>
# Ping interval for Mongo monitoring server.
#mms-interval = <seconds>
# Replication Options
# in replicated mongo databases, specify here whether this is a slave or master
#slave = true
#source = master.example.com
# Slave only: specify a single database to replicate
#only = master.example.com
# or
#master = true
#source = slave.example.com
# Address of a server to pair with.
#pairwith = <server:port>
# Address of arbiter server.
#arbiter = <server:port>
# Automatically resync if slave data is stale
#autoresync
# Custom size for replication operation log.
#oplogSize = <MB>
# Size limit for in-memory storage of op ids.
#opIdMem = <bytes>
# SSL options
# Enable SSL on normal ports
#sslOnNormalPorts = true
# SSL Key file and password
#sslPEMKeyFile = /etc/ssl/mongodb.pem
#sslPEMKeyPassword = pass

本地数据库导入到服务器Mongodb中
- 备份本地数据库
git切换到mongodb/data,输入：
../bin/mongodump -h 127.0.0.1:27017 -d databaseName -o ../data/backup
- git打包数据库
tar zcvf backup.tar.gz backup
- 上传到服务器
scp -P 3999 /D/MongoDB/data/backup.tar.gz root@120.78.177.221:/usr/local/mongodb/data
剩余步骤在服务器操作
- ssh登陆服务器后，解压数据库
cd /usr/local/mongodb/data
tar xvf backup.tar.gz
- 将数据导入到服务器的mongodb中(需要先启动Mongodb)
mongorestore --host 127.0.0.1:27017 -d databaseName ../data/backup
