1. 下载MongoDB、安装

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel80-4.4.18.tgz 
tar zxvf mongodb-linux-x86_64-rhel80-4.4.18.tgz

移动到/home路径下

mv mongodb-linux-x86_64-rhel80-4.4.18  /home  
cd  /home
mv mongodb-linux-x86_64-rhel80-4.4.18  mongodb

2. 配置MongoDB

cd mongodb
mkdir -p data logs conf

cd logs 
touch mongo.log 
cd .. /conf 
touch mongo.conf

编辑mongo配置文件 vim mongo.conf

dbpath=/home/mongodb/data
logpath=/home/mongodb/logs/mongo.log
logappend=true
journal=true
quiet=true
port=27017
bind_ip=0.0.0.0
fork=true

3. 防火墙开端口

firewall-cmd --add-port=27017/tcp --permanent  
service firewalld restart

4. 配置mongo启动脚本

cd
vim startMongo.sh
 /home/mongodb/bin/mongod --config /home/mongodb/conf/mongo.conf 

设置开机自启 vim /etc/rc.d/rc.local

 /home/mongodb/bin/mongod --config /home/mongodb/conf/mongo.conf 
chmod +x /etc/rc.d/rc.local  

报错处理

cd ../bin
./mongod

缺啥装啥 比如我的少

        libcrypto.so.1.1 => not found
        libssl.so.1.1 => not found

解决方法：

dnf -y install libcrypto.so.*

# mongo设置密码
cd /mongodb/bin
./mongo
use admin
db.createUser({user: 'root', pwd: 'password', roles: ['root']})
db.auth('root','password')

返回1代表对头了

vim /home/mongodb/conf/mongo.conf

auth = true # 是否开启校验用户,设置为true后数据库连接时需要输入用户名密码!!!!!!!!!!!!!

代码调试

xxx.db('mongodb://your name: your pwd@127.0.0.1:27017/Article');
