mongodb简述
1、下载安装mongodb
1 curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz # 下载 2 tar -zxvf mongodb-linux-x86_64-3.0.6.tgz # 解压 3 mv mongodb-linux-x86_64-3.0.6/ /usr/local/mongodb-3.0.6 # 将解压包拷贝到指定目录 4 ln -s /usr/local/mongodb-3.0.6/ /usr/local/mongodb # 创建软链接5 export PATH=/usr/local/mongodb:/bin:$PATH # 添加PATH变量6 mkdir -p /data/mongo_db #创建数据库目录(启动指定--dbpath,或写于配置文件)
2、配置文件
[root@vm-centos7 bin]# mkdir /usr/local/mongodb/etc/ [root@vm-centos7 bin]# cat /usr/local/mongodb/etc/mongod.conf #数据库数据存放目录 dbpath=/data/mongo_db/ #数据库日志存放目录 logpath=/var/log/mongodb/mongo.log #以追加的方式记录日志 logappend = true #端口号 默认为27017 port=27017 #以后台方式运行进程 fork=true #开启用户认证 auth=true #关闭http接口,默认关闭http端口访问 nohttpinterface=false #mongodb所绑定的ip地址 #bind_ip = 127.0.0.1 bind_ip = 0.0.0.0 #启用日志文件,默认启用 journal=true #这个选项可以过滤掉一些无用的日志信息,若需要调试使用请设置为false quiet=true
3、启动mongdb
mongod -f /usr/local/mongodb/etc/mongod.conf
4、连接并创建管理员
[root@vm-centos7 bin]# mongo MongoDB shell version: 3.0.6 connecting to: test Welcome to the MongoDB shell. For interactive help, type "help". For more comprehensive documentation, see http://docs.mongodb.org/ Questions? Try the support group http://groups.google.com/group/mongodb-user > > > > use admin switched to db admin > db admin > db.createUser({user:'linxu',pwd:'123456',roles:[{role:'userAdminAnyDatabase',db:'admin'}]}) Successfully added user: { "user" : "linxu", "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } > > exit bye
# 命令行测试
mongo -ulinxu -p '123456' 127.0.0.1:27017/admin
# mongo内部测试
[root@vm-centos7 bin]# mongo MongoDB shell version: 3.0.6 connecting to: test > > > db test > > show dbs 2017-05-20T00:20:02.610+0800 E QUERY Error: listDatabases failed:{ "ok" : 0, "errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }", "code" : 13 } at Error (<anonymous>) at Mongo.getDBs (src/mongo/shell/mongo.js:47:15) at shellHelper.show (src/mongo/shell/utils.js:630:33) at shellHelper (src/mongo/shell/utils.js:524:36) at (shellhelp2):1:1 at src/mongo/shell/mongo.js:47 > > use admin switched to db admin > > db admin > > show dbs 2017-05-20T00:20:13.923+0800 E QUERY Error: listDatabases failed:{ "ok" : 0, "errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }", "code" : 13 } at Error (<anonymous>) at Mongo.getDBs (src/mongo/shell/mongo.js:47:15) at shellHelper.show (src/mongo/shell/utils.js:630:33) at shellHelper (src/mongo/shell/utils.js:524:36) at (shellhelp2):1:1 at src/mongo/shell/mongo.js:47 > > db admin > > db.auth('linxu','123456') 1 > > show dbs admin 0.078GB local 0.078GB
5、创建普通用户
[root@vm-centos7 bin]# mongo -ulinxu -p '123456' 127.0.0.1:27017/admin MongoDB shell version: 3.0.6 connecting to: 127.0.0.1:27017/admin > > > db admin > > show dbs admin 0.078GB local 0.078GB > > use mydb switched to db mydb > > db mydb > > db.createUser({user:'nick',pwd:'123456',roles:[{role:'readWrite',db:'mydb'}]}) Successfully added user: { "user" : "nick", "roles" : [ { "role" : "readWrite", "db" : "mydb" } ] } > > db.auth('nick','123456') 1 >
6、查看所有存在的用户
> use admin switched to db admin > > db admin > > db.auth('linxu','123456') 1 > > db.system.users.find() { "_id" : "admin.linxu", "user" : "linxu", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "G1odVR9h/KMPQrOm/OgoXA==", "storedKey" : "IxV+sHbetC0D6y6o8nu+QuI81MQ=", "serverKey" : "07e+MxR1ZEM5BwsfKKLa5S6bIc4=" } }, "roles" : [{ "role" : "userAdminAnyDatabase", "db" : "admin" } ] } { "_id" : "mydb.nick", "user" : "nick", "db" : "mydb", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "q4/PoG2mrvBNc0WV7HIuyA==", "storedKey" : "TDKzZyJasK2D0xlRwlmewl87NQA=", "serverKey" : "lphcSnGgYUHMgBQ2aY+H8U7DAIk=" } }, "roles" : [ { "role" : "readWrite", "db" : "mydb" } ] } > >
