保存 install_mongo.sh

--.查看mongo是否启动
ps aux |grep mongo
--查看是否启动成功
--命令如下
ps -ef|grep mongo

systemctl start mongod.service
systemctl status mongod.service
设置为开机自启动
systemctl enable mongod.service 
systemctl enable mongod //开机自启MongoDB
systemctl start mongod  //启动MongoDB
systemctl status mongod //可以检查是否启动了MongoDB

netstat -an | grep 27017
netstat -ntulp  | grep 27017
netstat -lntup  | grep 27017
netstat -lanp | grep "27017"

find / -name mongodb.conf

cd /usr/local/mongodb-linux-x86_64-rhel70-3.6.5/conf/

vim mongodb.conf

7.在shell中使用mongo来连接mongodb,通过mongodb相关命令来进行mongodb的管理cd /usr/local/mongodb/bin./mongo

 

MongoDB对用户的操作

• 创建用户

MongoDB创建用户必须进入到相关数据库下进行创建

>use admin
>db.createUser({
user: 'admin', // 用户名（自定义）
pwd: 'my_db1', // 密码（自定义）
roles:[{
role: 'root', // 使用超级用户角色
db: 'admin' // 指定数据库
}]})

[root@k8s-vanode1 bin]# firewall-cmd --add-port=27017/tcp --zone=public --permanent
success
[root@k8s-vanode1 bin]# firewall-cmd --reload
