You will be able to install this from the ports collections if it is installed on your system. To do this, enter the following command:

# cd /usr/ports/security/sudo/
# make install clean

You can also install the sudo binary package using pkg:

# pkg install sudo

Add a Sudo User

First you need to create a user account to use with sudo

# adduser

Answer the questions from the suggested options to create a user. This tutorial will use user.example

Add User to Wheel Group

This group called “Wheel” limits the list of users who can use root

# pw group mod wheel -m user.example

Edit the sudoers file

First, you need to check the sudoers file with visudo extension

# visudo

Look for a wheelset. Remove comment if line is off. When you’re ready to save the file, it should look like this

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

Save and exit vi. ESC type, then : W Q, then ENTER

IMPORTANT! The visudo utility performs a syntax check before making changes to the file. The wrong sudoers file can break your system. Never edit /etc/sudoers directly. For example, if you make a mistake, you will see this when exiting visudo.

eSpeak is available as:

• A command-line program (Linux and Windows) for reading text from a file or from standard input;
• A version of the shared library for use by other programs. (On Windows, this is a DLL);
• The SAPI5 version is for Windows, so it can be used with screen readers and other programs that support the Windows SAPI5 interface;
• eSpeak has been ported to other platforms, including Android, Mac OSX, and Solaris.

Install eSpeak

To get started, you need to log in as the root user and run the following command to install eSpeak:

# pkg install espeak -y

Create Your First TTS Audio File

Test eSpeak by asking him to pronounce the letters y j w c t j when writing output as .wav file with name espeak-talk.wav in /tmp/ directory.
Next, we say that we need a space between 60, a pause between words. We also say that we want step 70 and a read speed of 100.

# espeak "y j w c t j" -w /tmp/espeak-talk.wav -g 60  -p 70 -s 100 -v en-uk

Now you’ll have a file with the name espeak-talk.wav located in /tmp/.

Update the package repository

\Before installing MongoDB, you need to make sure everything is up to date. This can be done by running the following command accordingly:

pkg update

There may be the following message stating that “package management tool” is not available, type Y, press Enter to continue. You can run pkg update -f a forced update if needed. If unsuccessful, go to step 2 – Installing MongoDB

Installing MongoDB

Install MongoDB using the following command:

pkg install mongodb

Start and Test The Installation of MongoDB

Check your MongoDB installation. This command will start the service:

service mongod onestart

The consol’ll look loke this:

MongoDB shell version: 4.4
connecting to: test
Welcome to the MongoDB shell.
For interactive help, type "help".
For more comprehensive documentation, see
    http://docs.mongodb.org/

    http://groups.google.com/group/mongodb-user

Turn the MongoDB at each boot

If you don’t want to use “onestart” to start Mongo on boot, you can configure it to run start instead. To do this, you need to edit /etc/rc.conf. with vi or any other text editor and add mongod_enable = “YES” to the file. Once finished, it will start when your server boots up and you can now use its service mongod start to start the Mongo service. Other service commands such as stop and status will also be available.

portsnap fetch extract

It usually takes a few minutes to download, and after the download is complete, you will proceed to the next step, which will be described.

Upgrade pkg

To install these ports that were recently downloaded, you need to update pgk by running the following command:

cd /usr/ports/ports-mgmt/pkg
make reinstall

Then you can already run the command to clean the directory from all temporary files:

make clean

Nginx installation

This command configures, compiles, and installs the Nginx web server

cd /usr/ports/www/nginx
make config-recursive

You will get the configuration pop up, and when you can choose the following: HTTP_GZIP_STATIC, HTTP_SSL, HTTP_DAV_EXT. It may be desirable to include other modules for compiling with Nginx. Then, install Nginx

make install

After the installation is complete, you will need to run the following to clear the directory of any files that will be created by this step:

make clean 

Configure Аutorun

To start nginx when your server boots up, edit /etc/rc.conf. You can edit this file by running ee /etc/rc.conf. Alternatively you can use nano. Nano can be installed by running pkg install nano

In /etc/rc.conf. you need to add nginx_enable = “YES” to the end of the file. Once this is done, you can proceed to the next step.

Starting Nginx

To start, enter the command:

service nginx start

If the launch was successful, you can see the output, which will be approximately the following:

Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful
Starting nginx.

To make sure Nginx is configured correctly, you can go to your IP address in a web browser. Go to http://0.0.0.0 (change the IP accordingly). If successful, you will see the “Welcome to Nginx!” Page
