• ubuntu18.04安装mongodb4.4


    1.下载对应的mongo版本

    1.查看linux版本:uname -a

      2.下载mongodb包

    下载地址: https://www.mongodb.com/try/download

    本地测试,我们下载community版本即可

      下载:wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1804-4.4.1.tgz

    二、配置

    1.创建数据库目录和log文件和所在目录

    mkdir -p /data/db
    mkdir -p /data/log/mongo/

    touch /data/log/mongo/mongodb.log

    2.编辑配置文件

    vim /etc/mongod.conf

    # 详细记录输出
    verbose = true
    
    # 指定服务端口号,默认端口27017
    port = 27017
    
    # 指定MongoDB日志文件,注意是指定文件不是目录
    logpath = /data/log/mongo/mongodb.log
    # 使用追加的方式写日志
    logappend = true
    
    # 指定数据库路径
    dbpath = /data/db/mongo/
    #设置每个数据库将被保存在一个单独的目录
    directoryperdb = true
    
    # 启用验证
    auth = false
    
    #以守护进程的方式运行MongoDB,创建服务器进程
    fork = true
    #安静输出
    quiet = true

    三、启动、验证

    cd /usr/local/mongodb/bin

    1.启动:./mongod -f /etc/mongod.conf 返回以下内容表示启动成功

      2.验证:pgrep mongo -l  有返回结果则证明启动成功

    四、常用命令

    本文只为其他项目而简单搭建环境,具体命令请查看官网等!

     1.进入shell模式:

    ./mongo

    2.查看数据库列表:

    > show dbs
    admin   0.000GB
    config  0.000GB
    local   0.000GB

    3.进入并创建数据数据库

    > use test
    switched to db test

    4.查看当前在哪个数据库

    > db
    test

    5.创建集合(数据表)

    > db.createCollection("test")
    { "ok" : 1 }

    6.向集合插入数据

    > db.test.insert({name:"哈哈",age:18})
    WriteResult({ "nInserted" : 1 })

    7.查看数据库中有哪些集合(数据表)

    > show collections
    test
    test2
    test3

    8.删除集合

    > db.test3.drop()
    true

    五、开启认证

    1.创建管理员账号

    > use admin
    switched to db admin
    > show collections
    system.version
    > db.system.version.find()
    { "_id" : "featureCompatibilityVersion", "version" : "4.4" }
    > db.createUser({user:"admin",pwd:"123456",roles:["root"]})
    Successfully added user: { "user" : "admin", "roles" : [ "root" ] }

     2.开启认证

    vim /etc/mongod.conf  

    auth = true #将auth设置为true

    3.重新登录

    root@ubuntu1:/usr/local/mongodb/bin# ./mongo
    MongoDB shell version v4.4.1
    connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
    Implicit session: session { "id" : UUID("738b99c4-a57e-467b-8d60-15f5e0007ce8") }
    MongoDB server version: 4.4.1
    > use admin
    switched to db admin
    > db.auth("admin","123456")
    1
    > show dbs
    admin   0.000GB
    config  0.000GB
    local   0.000GB
    test    0.000GB

     4.为数据库添加用户

    > use test
    switched to db test
    > db.createUser({user:"test",pwd:"123456",roles:[{role:"dbOwner",db:"test"}]})
    Successfully added user: {
        "user" : "test",
        "roles" : [
            {
                "role" : "dbOwner",  #权限
                "db" : "test"     #数据库
            }
        ]
    }

    5.用数据库用户test登录

    root@ubuntu1:/usr/local/mongodb/bin# ./mongo
    MongoDB shell version v4.4.1
    connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
    Implicit session: session { "id" : UUID("ca9ce18c-be3b-4f7a-af77-50db106c9676") }
    MongoDB server version: 4.4.1
    > use test
    switched to db test
    > db.auth("test","123456")
    1
    > show dbs
    test  0.000GB
    > db
    test
    > show collections
    test
    test2

    6.删除用户

    > use admin
    switched to db admin
    > db.system.users.find()
    { "_id" : "admin.admin", "userId" : UUID("a3a3c4b2-6984-44a1-80d4-112bad3fd86f"), "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "Edm0oEf+DCxBvjIAbg9V6Q==", "storedKey" : "GY8/71b+NRD2IlNAtPJTjxGZ34o=", "serverKey" : "AoSfWXn3MkOJcax7vU02a4LmTmA=" }, "SCRAM-SHA-256" : { "iterationCount" : 15000, "salt" : "nc3gzY+tLBNy4HGE0SXBQz0+7QMjYpbkZ9I+1w==", "storedKey" : "dlEriAdL5XE5CyhOwXGhvm9pmKRtfIGyVXkz8x0YX3w=", "serverKey" : "Oxw7bKeEcZ1FftFLY3xON6tTZS7KS/VsR5bUPQwWlXM=" } }, "roles" : [ { "role" : "root", "db" : "admin" } ] }
    { "_id" : "test.test", "userId" : UUID("5ddc0a8e-d799-4900-ba58-4adc4f04d73f"), "user" : "test", "db" : "test", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "7JzzsLSOQbd3+/pfavT3aQ==", "storedKey" : "M/9gUQTJGEm+Jp/z2e8hPyHeBeo=", "serverKey" : "sCPbv9Aj7Pdub9mPmQHG7Fq6hbY=" }, "SCRAM-SHA-256" : { "iterationCount" : 15000, "salt" : "bLSGy+lL7nepxvbhOCxGejmGd04p2ZM2QU1YYw==", "storedKey" : "NAoLCNhAZ2MtVJk/LKTKD3JiX501SiG9AL5MDn9FzcA=", "serverKey" : "kQ3SK6QEquFuUrlPKE5s0xveQ4s5SIaii8w5hx4jDt4=" } }, "roles" : [ { "role" : "dbOwner", "db" : "test" } ] }
    > db.dropUser("test")   #admin数据库内不能删除test数据库下面的test用户
    false
    > use test
    switched to db test
    > db.dropUser("test")  #必须切换到被删除用户所在数据库才能删除
    true
    > use admin
    switched to db admin
    > db.system.users.find()
    { "_id" : "admin.admin", "userId" : UUID("a3a3c4b2-6984-44a1-80d4-112bad3fd86f"), "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "Edm0oEf+DCxBvjIAbg9V6Q==", "storedKey" : "GY8/71b+NRD2IlNAtPJTjxGZ34o=", "serverKey" : "AoSfWXn3MkOJcax7vU02a4LmTmA=" }, "SCRAM-SHA-256" : { "iterationCount" : 15000, "salt" : "nc3gzY+tLBNy4HGE0SXBQz0+7QMjYpbkZ9I+1w==", "storedKey" : "dlEriAdL5XE5CyhOwXGhvm9pmKRtfIGyVXkz8x0YX3w=", "serverKey" : "Oxw7bKeEcZ1FftFLY3xON6tTZS7KS/VsR5bUPQwWlXM=" } }, "roles" : [ { "role" : "root", "db" : "admin" } ] }
