大家早上好呀，今天天气不错，老哥心情很好，加上快放五一了，内心炒鸡激动！！！哈哈哈哈哈哈
放假之前，想写一篇文章，安抚自己骚动的心
今天给大家带来的是全新的MongoDB安装，分为Linux版和Docker，为什么要分两个版本呢？这是因为有些小伙伴们（包括我）有时候会用到Docker，所以以后尽量出两个版本，方便小伙伴们的学习。
闲话不扯了，开始安装
1、访问MongoDB 官网，选择对应版本，MongoDB下载
2、手动上传tgz包到服务器
[root@VM-4-12-centos mongodb]# pwd
/opt/mongodb
[root@VM-4-12-centos mongodb]# ll
total 84248
-rw-r--r-- 1 root root 86267589 Apr 29 09:34 mongodb-linux-x86_64-rhel80-5.0.8.tgz
3、解压
[root@VM-4-12-centos mongodb]# tar -zxvf mongodb-linux-x86_64-rhel80-5.0.8.tgz
mongodb-linux-x86_64-rhel80-5.0.8/LICENSE-Community.txt
mongodb-linux-x86_64-rhel80-5.0.8/MPL-2
mongodb-linux-x86_64-rhel80-5.0.8/README
mongodb-linux-x86_64-rhel80-5.0.8/THIRD-PARTY-NOTICES
mongodb-linux-x86_64-rhel80-5.0.8/bin/install_compass
mongodb-linux-x86_64-rhel80-5.0.8/bin/mongo
mongodb-linux-x86_64-rhel80-5.0.8/bin/mongod
mongodb-linux-x86_64-rhel80-5.0.8/bin/mongos
3A、名字太长了，重命名，然后放到user/local下面，方便启动
[root@VM-4-12-centos mongodb]# mv mongodb-linux-x86_64-rhel80-5.0.8 mongodb
[root@VM-4-12-centos mongodb]# mv mongodb /usr/local/mongodb
5、切换到user/local
[root@VM-4-12-centos mongodb]# cd /usr/local/mongodb/
6、Linux安装到user/local,建议设置环境变量
[root@VM-4-12-centos mongodb]# echo $PATH
/opt/redis01/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/opt/jdk01/jdk1.8.0_311/bin:/root/bin
[root@VM-4-12-centos mongodb]# export PATH=/usr/local/mongodb/bin:$PATH
[root@VM-4-12-centos mongodb]# mongo --version
MongoDB shell version v5.0.8
Build Info: {
"version": "5.0.8",
"gitVersion": "c87e1c23421bf79614baf500fda6622bd90f674e",
"openSSLVersion": "OpenSSL 1.1.1k FIPS 25 Mar 2021",
"modules": [],
"allocator": "tcmalloc",
"environment": {
"distmod": "rhel80",
"distarch": "x86_64",
"target_arch": "x86_64"
}
}
7、创建文件夹，配置MongoDb日志、数据、进程存放位置
[root@VM-4-12-centos mongodb]# ll
total 136
drwxr-xr-x 2 root root 4096 Apr 29 09:48 bin
-rw-rw-r-- 1 lighthouse lighthouse 30608 Apr 22 05:15 LICENSE-Community.txt
-rw-rw-r-- 1 lighthouse lighthouse 16726 Apr 22 05:15 MPL-2
-rw-rw-r-- 1 lighthouse lighthouse 1977 Apr 22 05:15 README
-rw-rw-r-- 1 lighthouse lighthouse 76823 Apr 22 05:15 THIRD-PARTY-NOTICES
[root@VM-4-12-centos mongodb]# mkdir data && mkdir log && mkdir pid
8、MongoDb没有默认conf,需要我们创建文件夹conf
[root@VM-4-12-centos mongodb]# pwd
/usr/local/mongodb
[root@VM-4-12-centos mongodb]# mkdir conf && cd ./conf
[root@VM-4-12-centos mongodb]# vim mongodb.conf
#数据保存路径
dbpath=/usr/local/mongodb/data/
#日志保存路径
logpath=/usr/local/mongodb/mongo.log
#进程描述文件
pidfilepath=/usr/local/mongodb/pid/mongo.pid
#日志追加写入
logappend=true
bind_ip_all=true
#mongo默认端口
port=27017
#操作日志容量
oplogSize=10000
#开启子进程
fork=true
#需要登录认证
#auth=true
9、Esc ，然后 :wq! 退出
10、启动，成功！如果报错了，lsof -i:27017查看端口是否已经存在，如果存在,kill -9 杀掉进程号
[root@VM-4-12-centos mongodb]# ./bin/mongod --config /usr/local/mongodb/conf/mongodb.conf --fork
about to fork child process, waiting until server is ready for connections.
forked process: 799704
child process started successfully, parent exiting
11、输入进入命令，出现以下提示，说明安装成功！
[root@VM-4-12-centos mongodb]# mongo
-------------------------------------------------------------------------------->
12、下面是Docker版安装，Linux版的同志们可以先撤了，别忘了关注、点赞、收藏三连哦
13、拉取镜像
[root@VM-4-12-centos /]# docker pull mongo:latest
14、运行镜像
[root@VM-4-12-centos /]# docker run -d --restart=always -p 27017:27017 --name mymongo -v /data/db:/data/db -d mongo
15、查看是否启动成功
[root@VM-4-12-centos /]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
712f16d4efa2 mongo "docker-entrypoint.s…" 18 seconds ago Up 17 seconds 0.0.0.0:27017->27017/tcp, :::27017->27017/tcp mymongo
15c86a310820 rabbitmq "docker-entrypoint.s…" 18 hours ago Up 18 hours 4369/tcp, 0.0.0.0:5672->5672/tcp, :::5672->5672/tcp, 5671/tcp, 15691-15692/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp, :::15672->15672/tcp Jessica-RabbitMQ
16、进入mongodb容器
[root@VM-4-12-centos /]# docker exec -it 712f16d4efa2 /bin/bash
root@712f16d4efa2:/#
root@712f16d4efa2:/# mongo
17、基本数据库命令
查看数据库
> show dbs
查看版本
> db.version();
创建/切换数据库
> use test
18、CRUD
新增
> db.Test.save({name:'Jessica',password:123,sex:'man'})
> db.Test.save({name:'Jessica',password:123,sex:'man'})db.Test.save({name:'Jessica',password:123,sex:'man'})
WriteResult({ "nInserted" : 1 })
查询
> db.Test.find({name:'Jessica'})
> db.Test.find({name:'Jessica'})db.Test.find({name:'Jessica'})
{ "_id" : ObjectId("626b578ed0c0eb6cdbec268d"), "name" : "Jessica", "password" : 123, "sex" : "man" }
修改
db.Test.update({name:'Jessica'},{$set:{password:456,sex:'superman'}})
> db.Test.update({name:'Jessica'},{$set:{password:456,sex:'superman'}})db.Test.update({name:'Jessica'},{$set:{password:456,sex:'superman'}})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
删除
db.Test.remove({name:'Jessica'})
> db.Test.remove({name:'Jessica'})db.Test.remove({name:'Jessica'})
WriteResult({ "nRemoved" : 1 })
