2021-09-24 09:19:27

操作系統(tǒng)：CentOS?7

在mongodb的官網(wǎng)可以直接下載到對(duì)應(yīng)的rpm包，然后使用yum進(jìn)行安裝。

yum?-y?localinstall?mongodb-org-mongos-4.4.8-1.el7.x86_64.rpm??mongodb-org-server-4.4.8-1.el7.x86_64.rpm??mongodb-org-shell-4.4.8-1.el7.x86_64.rpm

systemctl?enable?mongod
systemctl?start?mongod

查看啟動(dòng)文件

systemctl?cat?mongod

可以看出數(shù)據(jù)目錄文件/var/run/mongodb，配置文件是/etc/mongod.conf

默認(rèn)是沒(méi)有設(shè)置密碼，可以直接輸入mongo命令就可以直接登陸shell進(jìn)行操作。

mongo

創(chuàng)建管理用戶

use?admin
db.createUser({user:"root",pwd:"opcai.TOP",roles:["root"]})

修改配置文件

vim?/etc/mongod.conf

配置security啟用驗(yàn)證。

...
security:
??authorization:?enabled
...

重啟服務(wù)生效

systemctl?restart?mongod

Mongodb目前應(yīng)用也比較多，維護(hù)也相對(duì)簡(jiǎn)單。
