mv mongodb-linux-x86_64-rhel70-4.0.2 mongodb配置MONGODB_HOME
vim ~/.bash_profile
export MONGODB_HOME=/usr/local/mongodb
export PATH=$PATH:$MONGODB_HOME/bin使修改生效
source ~/.bash_profile新建目录和文件

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

> 基本操作
- 建立用户
use admin
db.createUser(
{
user: "dba",
pwd: "123456",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)- 建立数据库
use web
db.items.insert({"name":"web"})- 给新创建的库加入用户
use web
db.createUser(
{
user: "web",
pwd: "123456",
roles: [ { role: "readWrite", db: "web" } ]
}
)- 关闭数据库
use admin
db.shutdownServer()- 常用命令
use dbname # 使用哪个数据库
db.auth("user","pwd") # 验证
show dbs # 显示所有数据库
show users # 显示当前数据库的所有用户
db.dropDatabase() # 删除数据库
db.shutdownServer() # 关闭数据库- 备份恢复数据库
备份
mongodump -d <数据库名><文件夹目录>
恢复
mongorestore -d <数据库名><文件夹目录>系统句柄调优（根据实际情况而定）
vim /etc/security/limits.conf
mongod soft nofile 64000
mongod hard nofile 64000
mongod soft nproc 32000
mongod hard nproc 32000登录认证
上面的配置是没有密码认证的，实际环境中是要加登录验证的
修改mongod.conf 添加下面的内容：
security:
authorization: enabled重启mongodb，再次登录（我们以前面配置的dba账户为例（dba账户配置的密码为123456））
首先连接mongo，在进行认证
