Question

I want to install MongoDB in my AWS Cloud9 server. So I followed the instruction as the Cloud9 community page says, but the command to run the MongoDB server in c9 command line i.e.,
$ *./mongod* returns ./mongod: line 1: mongod: command not found.
help me to fix this.
I've tried searching about it on YouTube but it didn't work.
$ *sudo yum install -y mongodb-org*
Loaded plugins: priorities, update-motd, upgrade-helper
1062 packages excluded due to repository priority protections
No package mongodb-org available.
Error: Nothing to do
$ mkdir data
$ echo 'mongod --bind_ip=$IP --dbpath=data --nojournal --rest "$#"' > mongod
$ chmod a+x mongod
$ ./mongod
./mongod: line 1: mongod: command not found
We can start mongodb by running the mongod script on your project root:
command :- ./mongod

From the error given below, it is apparent that the mongo repo wasn't configured in your yum package manager.
vocstartsoft:~ $ sudo yum install -y mongodb-org
Loaded plugins: priorities, update-motd, upgrade-helper 1062 packages excluded due to repository priority protections No package mongodb-org available. Error: Nothing to do
Create /etc/yum.repos.d/mongodb-org-4.0.repo and write the following in it.
[mongodb-org-4.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
Or add the repo directly from the .repo file,
yum-config-manager --add-repo https://repo.mongodb.org/yum/amazon/mongodb-org.repo
Then run,
sudo yum install -y mongodb-org

Either try this: sudo apt install mongodb-clients
Or consider the below process:
ubuntu:~/environment $ At the terminal you’ll see this.
Enter touch mongodb-org-3.6.repo into the terminal
Now open the mongodb-org-3.6.repo file in your code editor (select it from the left-hand file menu) and paste the following into it then save the file:
[mongodb-org-3.6]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/3.6/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.6.asc
* Now run the following in your terminal:
sudo mv mongodb-org-3.6.repo /etc/yum.repos.d
sudo yum install -y mongodb-org
If the second code does not work try:
sudo apt install mongodb-clients
Close the mongodb-org-3.6.repo file and press Close tab when prompted
Change directories back into root ~ by entering cd into the terminal then enter the following commands:
“ubuntu:~ $ “ - Terminal should look like this.
sudo mkdir -p /data/db
echo 'mongod --dbpath=data --nojournal' > mongod
chmod a+x mongod
Now test mongod with ./mongod
Remember, you must first enter cd to change directories into root ~ before running ./mongod
Don't forget to shut down ./mongod with ctrl + c each time you're done working
-if this error pops up while using command mongod
exception in initAndListen: IllegalOperation: Attempted to create a lock file on a read-only directory: /data/db, terminating
Then use the code:
sudo chmod -R go+w /data/db
