mongodb下载地址：

https://docs.mongodb.com/manual/installation/

其中server仅包含mongodb server，shell仅包含mongo客户端命令mongo

rpm可以用yum或者rpm安装，tgz直接解压并配置path就可以使用

最后那个tgz包包含了所有组件（mongos，shell和server），直接解压就可以使用

 

我这次是server和shell分开安装的

1.安装server

[root@lzl soft]# rpm -ivh mongodb-server-4.4.2-el6x86.rpm

warning: EasyConnectPlugin.dmg: Header V3 RSA/SHA1 Signature, key ID 90cfb1f5: NOKEY

   1:mongodb-org-server    ########################################### [100%]

 

[root@lzl mongo]# ls -lrt /usr/bin/mongo*

-rwxr-xr-x 1 root root 82214928 Nov 17 00:12 /usr/bin/mongod

 

2.启动server

[root@lzl ~]# mongod -f /etc/mongod.conf &

[1] 4901

about to fork child process, waiting until server is ready for connections.

forked process: 4903

 

[root@lzl ~]# child process started successfully, parent exiting

 

[1]+  Done                    mongod -f /etc/mongod.conf

[root@lzl ~]# ps -ef|grep mongo

root      4903    1 17 11:54 ?        00:00:01 mongod -f /etc/mongod.conf

root      4938 4808  0 11:54 pts/9    00:00:00 grep mongo

 

3.安装mongo shell

 

[root@lzl soft]# rpm -ivh mongodb-org-shell-4.4.2-1.el6.x86_64.rpm

warning: mongodb-org-shell-4.4.2-1.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID 90cfb1f5: NOKEY

   1:mongodb-org-shell     ########################################### [100%]

 

[root@lzl soft]# which mongo

/usr/bin/mongo

[root@lzl soft]# which mongod

/usr/bin/mongod

[root@lzl soft]# 

 

[root@lzl soft]# mongo

        Enable MongoDB's free cloud-based monitoring service, which will then receive and display
        metrics about your deployment (disk utilization, CPU, operation statistics, etc).

        The monitoring data will be available on a MongoDB website with a unique URL accessible to you
        and anyone you share the URL with. MongoDB may use this information to make product
        improvements and to suggest MongoDB products and deployment options to you.

        To enable free monitoring, run the following command: db.enableFreeMonitoring()
        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
