echo "$systemd_content" > $systemd_path
systemctl daemon-reload
echo $'\n-----Starting app-----\n'
sudo systemctl start app
sudo systemctl enable app
echo $'\n-----Done-----\n'
cd Runner/scripts
  • Creating Nginx files with server_ip and config the sites-available with sites-enabled and linking them togather.
#!/bin/bashcd ../../if [ /etc/nginx/sites-available/app ];
echo $'\n-----Removing existing nginx app-----\n';
sudo rm /etc/nginx/sites-available/app;
sudo rm /etc/nginx/sites-enabled/app;
systemctl daemon-reload

echo "setting $1 as server domain"
config=$'server {\n\tlisten 80;\n\tserver_name '$var_server_ip$';\n\nlocation / {\n\tinclude proxy_params;\n\tproxy_pass http://unix:'$DIR$'/app.sock;\n\t}\n}\n'
echo $'\n-----Creating nginx sites-available-----\n';
echo "$config" > $nginx_path
echo $'\n-----Linking nginx server-----\n';
sudo ln -s $nginx_path /etc/nginx/sites-enabled
echo $'\n-----Testing nginx server-----\n';
sudo nginx -t
echo $'\n-----Restarting nginx server-----\n';
sudo systemctl restart nginx
echo $'\n-----Adjusting firewall to allow access to nginx server-----\n';
sudo ufw allow 'Nginx Full'
echo $'\n-----Done-----\n';
cd Runner/scripts
  • Creating a bash to pass arguments to the specific bash file.
#!/bin/bashecho $'\n-----Welcome to the EasyDeployer-----\n'cd scripts
source git_reset_and_pull.sh
