1.在mongoDB中[下载tar.gz][tar.gz]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dpdGh1Yl8zODkyNDY5NQ_size_16_color_FFFFFF_t_70]  
（也可以直接在linux中使用wget命令：wget https://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-4.0.12.tgz）  
2.在linux的/opt中新建mongdb，以及存放log和data的目录

cd /opt
    mkdir mongodb
    cd mongodb
    mkdir logs
    mkdir data
    chmod 777 data/

3.将下载好的tar.gz上传到/opt/mongodb中并解压

tar -zxvf mongodb-linux-x86_64-4.0.12.tgz

4.将解压后的文件移动到/opt/mongodb

mv /opt/mongodb/mongodb-linux-x86_64-4.0.12/* /opt/mongodb

5.进入bin中启动服务

cd /opt/mongodb/bin
    ./mongod --dbpath=/opt/mongodb/data --logpath=/opt/mongodb/logs/mongodb.log --logappend --port=27017 --fork

6.链接

./mongo

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dpdGh1Yl8zODkyNDY5NQ_size_16_color_FFFFFF_t_70 3]  
7.测试

use test

可以在/etc/profile中配置变量：

vim /etc/profile

在里面加入以下内容：

# mongodb
    export PATH=$PATH:/opt/mongodb/bin

执行 source /etc/profile

在bin中新建mongodb.conf文件，内容如下：其中fork表示以守护线程运行

dbpath=/opt/mongodb/data
    logpath=/opt/mongodb/logs/mongodb.log
    port=27017
    fork=true

启动时命令如下：  
mongod -f /opt/mongodb/bin/mongodb.conf  
设置开机自启动  
1.在/lib/systemd/system/创建mongodb.service内容如下：

[Unit]
    Description=mongodb
    After=network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=forkingExecStart=/opt/mongodb/bin/mongod --config /opt/mongodb/bin/mongodb.conf
    ExecReload=/bin/kill -s HUP $MAINPIDExecStop=/opt/mongodb/bin/mongod --shutdown --config /opt/mongdb/bin/mongodb.conf
    PrivateTmp=true
    
    [Install]
    WantedBy=multi-user.target

2.修改文件权限：chmod 754 mongodb.service  
3.启动mongodb服务:systemctl start mongodb.service  
4.设置开机自启动：systemctl enable mongodb.service

如果启动出现以下错误：

执行：systemctl daemon-reload
