1、解压mongodb到/opt/mongo

2、新建配置文件

vim /opt/mongodb/conf/mongodb.conf
#数据文件路径
dbpath=/data/mongodb/
#日志路径
logpath=/opt/mongodb/logs/mongodb.log

#端口
port=27017

logappend=true
#是否以守护进程方式运行
fork=true

bind_ip=0.0.0.0

3、启动

/opt/mongodb/bin/mongod -f /opt/mongodb/conf/mongodb.conf

4、连接配置

默认连接上去不用密码

创建data数据库并授权账号密码

use data
db.createUser(
    {
      user: "user1",
      pwd: "123456",
      roles: ["readWrite"]
    }
 ) 

#登录认证
db.auth("user1","123456")

#删除数据库用户
db.dropUser("user1")
