I just had in trouble with this and found very clear solution

If you want to push single file

scp -P port /home/dir/dir/file.tar.gz root@server_ip:/home/dir/or_new_dir/newfile.tar.gz

And scp can push multiple files and folders ,

scp -rp  -P port /home/target_folder/ root@server_ip:/home/destination_folder

Good luck 😉

Recently i was looking for installation guide on internet but almost every documentation is outdated even on redmine.org

Lets start

At first you need to install centos 7.5 clearly, minimal configuration is recommended

Update the system and install necessary packages

yum update
yum install curl zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel ftp wget ImageMagick-devel gcc-c++ patch readline readline-devel zlib libyaml-devel libffi-devel make bzip2 autoconf automake libtool bison subversion sqlite-devel

Installing Mariadb

To install the MariaDB package, run:

yum install mariadb-server

After this command first-run-installation shoud done by run:

mysql_secure_installation

Last step for database:

mysql -uroot -p
CREATE DATABASE redmine CHARACTER SET utf8;
GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost' IDENTIFIED BY 'redmine_passwd';
FLUSH PRIVILEGES;
exit;

Redmine user

To run redmine , you need to add new user for redmine

 sudo adduser --home /opt/redmine --shell /bin/bash redmine
sudo install -d -m 755 -o redmine -g redmine /opt/redmine

Impersonalize as redmine:

sudo su - redmine

Installing Ruby using RVM

curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable --ruby

Lets start installed rvm

source ~/.rvm/scripts/rvm
rvm --default use ruby

To check for everything is fine:

ruby --version
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]

Installing Redmine

Following codes are install redmine on home state eg(opt/home) and prepeare config files for you.

cd && svn co http://svn.redmine.org/redmine/branches/3.4-stable redmine
mkdir -p ./redmine/tmp/pids ./redmine/public/plugin_assets
cp ./redmine/config/configuration.yml.example ./redmine/config/configuration.yml
cp ./redmine/config/database.yml.example ./redmine/config/database.yml

Database.yml file should be filled as given password or root password from mariadb.

vi nsno

production:
  adapter: mysql2
  database: redmine
  host: localhost
  username: redmine
  password: "redmine_passwd"
  encoding: utf8

Installing gems

cd /opt/redmine/redmine
echo "gem 'puma'" >> Gemfile.local
echo "gem: --no-ri --no-rdoc" >> ~/.gemrc 
gem install bundler
bundle install --without development test postgresql sqlite

Migrating and last touch

rake generate_secret_token
RAILS_ENV=production rake db:migrate
RAILS_ENV=production REDMINE_LANG=en rake redmine:load_default_data

Puma installation and configuration

Create a new configuration file as follows:

vim ./redmine/config/puma.rb

#!/usr/bin/env puma

application_path = '/opt/redmine/redmine'
directory application_path
environment 'production'
daemonize true
pidfile "#{application_path}/tmp/pids/puma.pid"
state_path "#{application_path}/tmp/pids/puma.state"
stdout_redirect "#{application_path}/log/puma.stdout.log", "#{application_path}/log/puma.stderr.log"
bind "tcp://0.0.0.0:5000"

Start Puma

Start the puma server with :

cd /opt/redmine/redmine/ && bundle exec puma --config config/puma.rb

The output should be similar to the following:

Puma starting in single mode...
* Version 3.11.2 (ruby 2.4.1-p111), codename: Love Song
* Min threads: 0, max threads: 16
* Environment: production
* Daemonizing...

Do not forget Stop firewall

I prefer stop firewall at this phase, if you wish only allow port, to stop firewall

sudo firewall-cmd --state
sudo systemctl stop firewalld

Lets Test 1.2.3.

Finally your can start your browser and access your new Redmine installation at: http://your_server_ip:5000

Happy coding.

Today i faced one of this “Twig_Cache_Null” that was meanless.

After Several inspections i found solution:

Empty and readable cache folder is not exists. You need to create at “config” described:

1. new Twig_Environment($loader, array(
2. ‘cache’ => ‘cache/twig’,
3. ‘debug’ => …,
4. )

Happy coding.

Apache cordova is an excellent tool for generate multiple platforms applications. Lets Make a fast start for it;

1- Install cordova with NPM’s , thats easy with terminal

$ sudo npm install -g cordova

2- And lets create a hello app

$ cordova create hello com.example.hello HelloWorld

3- Due to create automatically creating splashscreen images run commands below

$ sudo npm install cordova-icon -g
$ sudo npm install cordova-splash -g

4- At this phase we need to have 2 different images , First one should 1240x1240px dimension square for icon.png, second one is  2208×2208px dimension has centered image with logo,

5- After creating two images we need to run commands below.

$ cordova-icon --config=config.xml --icon=icon.png
$ cordova-splash --config=config.xml --splash=splash.png

6- I want to test on Ios Simulator but , is there simulators available in my repo? Better to check with command below;

$ cordova emulate ios --list

If there is an output like below that looks fine;

Available iOS Simulators:
        iPhone-5s, 12.1
        iPhone-6, 12.1
        iPhone-6-Plus, 12.1
        iPhone-6s, 12.1
        iPhone-6s-Plus, 12.1
        iPhone-7, 12.1
        iPhone-7-Plus, 12.1
......

7- Any of those simulators is available , i want to use 8-Plus , you can use whatever you want

cordova emulate ios --target="iPhone-8-Plus, 12.1" --buildFlag="-UseModernBuildSystem=0"

8- Similar to Ios device lets check android devices:

$ cordova emulate android --list

After checking this find out last application step

cordova platform rm android
cordova platform add android

Do not forget:
If test bytes are gets low, and you have single disk; your disk going to die soon,
And if you get unstable results and you are using raid; check your disks status. Maybe one of your disk alredy died.

Happy coding.

There are lots of error returns when you trying to set up such as
cp: cannot stat ‘/var/cpanel/templates/apache2/vhost default’: No such file or d irectory
or
cp: cannot create regular file `/var/cpanel/apps/nginxcp.conf': No such file or directory

There is a solution for now: engintron
easy to install

cd /  
rm -f engintron.sh  
wget --no-check-certificate https://raw.githubusercontent.com/engintron/engintron/master/engintron.sh  
bash engintron.sh install

Happy codings 🙂

Today most web application is detecting by bots or spiders. Some of them looking for your security issues. You can handle it with simple moves. 

If you filter just like below, there is a one more layer for your critical procedures. Because lots of spiders or crawlers does not have skill for set request type.

[php]
/* XHR-AJAX check */
if(!empty($_SERVER[‘HTTP_X_REQUESTED_WITH’]) && strtolower($_SERVER[‘HTTP_X_REQUESTED_WITH’]) == ‘xmlhttprequest’){
/*Your Procedures or processes */
}else{
/*Here is a direct call or bot */
die(‘you shall not pass!’);
}
[/php]
Simple.
