Alternatively you can use this script to automate everything except the cfg.tf configuration. To run it do the following.

git clone https://github.com/BurningSmile/LinuxScripts.git
cd LinuxScripts
chmod +x auto-tf2serverinstall.sh
sudo ./auto-tf2serverinsall.sh
Then simply follow the steps for generating a cfg.tf server configuration. Finally reboot your VPS with the following commands.
su - tf2server -c '/home/tf2server/tf2server stop'
reboot

Create a tf2server account
useradd -m --password default tf2server

Create a password for the account
passwd tf2server

Change to the account
su - tf2server

Download the tf2 server management stack
wget -N --no-check-certificate https://gameservermanagers.com/dl/linuxgsm.sh && chmod +x linuxgsm.sh && bash linuxgsm.sh tf2server

Install the server
./tf2server auto-install

Lgsm has recently changed the way they handel server settings. You now copy them to a file in the directory $HOME/lgsm/configs-lgsm/tf2server/tf2server.cfg. Use the following commands to setup this file with the items you will most likely be changing.
vim /home/tf2server/lgsm/config-lgsm/tf2server/tf2server.cfg
Add the following
defaultmap="cp_badlands"
maxplayers="16"
updateonstart="on"
Save the file

Allow tf2server through the firewall.

This will setup our firewall. I setup up firewalls to block all incoming traffic that is not whitelisted.

https://www.metamodsource.net/downloads.php?branch=stable
wget (link here)
tar -xvf mmsource (Use tab completion)
rm mmsource (tab complete)

Now for sourcemod:
Go to the souremod site and copy its link address for the Linux version.
https://www.sourcemod.net/downloads.php?branch=stable
wget (link here)
tar -xvf sourcemod (tab complete)
rm sourcemod

Setting up admin account
vim ./addons/souremod/config/admins_simple.ini

Go to a steamidfinder.com
Paste your steam url and paste the steam id. Follow the below example
“STEAMID” “99:z” //useraccountname

Go to cfg.tf and follow my example for configuring the server.

Custom settings used in video. Remember to replace IP-GOES-HERE with the ip of your vps.
// Server downloads and files
net_maxfilesize "64"
sv_downloadurl "http://IP-GOES-HERE/fastdl/tf2/"
sv_allowdownload "1"
sv_allowupload "1"
sv_consistency "1"

Unzip the file and upload it to your server in sftp to your serverfiles/tf directory, overwrite any files if asked.

Start the server via ssh
./tf2server start

Automate a restart at midnight. And automate the SRCDS instance starting on server start and restart.
Refer to crontab documentation if needed.
https://linux.die.net/man/5/crontab
https://help.ubuntu.com/community/CronHowto

crontab -e
Choose 3 to use vim
Add the following in insert mode

0 0 * * * /home/tf2server/tf2server restart
@reboot /home/tf2server/tf2server start

Save the file and exit vim

Ensure the crontab file works
./tf2server stop
exit
reboot

After the reboot make sure your Srcds instance starts on boot.
