## 1.在官网下载想要的版本 ##

[https://www.mongodb.com/try/download/community][https_www.mongodb.com_try_download_community]

## 2.上传后解压 ##

1）创建db和logs文件夹

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQyMDkyMDU_size_16_color_FFFFFF_t_70 1][]

2）创建mongodb.conf文件

port=27017 #端口
    dbpath= /opt/tools/mongodb/db #数据库存文件存放目录
    logpath= /opt/tools/mongodb/logs/mongodb.log #日志文件存放路径
    logappend=true #使用追加的方式写日志
    fork=true #以守护进程的方式运行，创建服务器进程
    maxConns=100 #最大同时连接数
    noauth=true #不启用验证
    journal=true #每次写入会记录一条操作日志（通过journal可以重新构造出写入的数据）。
    #即使宕机，启动时wiredtiger会先将数据恢复到最近一次的checkpoint点，然后重放后续的journal日志来恢复。
    storageEngine=wiredTiger  #存储引擎有mmapv1、wiretiger、mongorocks
    bind_ip = 0.0.0.0  #这样就可外部访问了，例如从win10中去连MongoDB

## 3.配置环境变量 ##

## 4.启动mongodb ##

[root@common mongodb]# mongod -f mongodb.conf 
    about to fork child process, waiting until server is ready for connections.
    forked process: 13406
    ERROR: child process failed, exited with 100
    To see additional information in this output, start without the "--fork" option.

启动时一直有上面的报错，查看日志发现路径拼错了

修改后，即可：

[root@common mongodb]# mongod -f mongodb.conf 
    about to fork child process, waiting until server is ready for connections.
    forked process: 13522
    child process started successfully, parent exiting

## 5.下载robo 3T可视化工具 ##

## 6.本地连接服务器上mongodb ##

这里涉及到具体的数据库的账户密码，可以通过如下操作来创建

//使用admin数据库
    use admin
    
    //给admin数据库添加管理员用户名和密码，用户名和密码请自行设置
    db.createUser({user:"admin",pwd:"123456",roles:["root"]})
    
    //验证是否成功，返回1则代表成功
    db.auth("admin", "123456")
    
    //切换到要设置的数据库,以test为例
    use test
    
    //为test创建用户,用户名和密码请自行设置。
    db.createUser({user: "test", pwd: "123456", roles: [{ role: "dbOwner", db: "test" }]})

那这样就连接成功了
