Ubuntu Server

Setup

• Packages

  1. Required

     For python-dev it depend on the python version installed.

      sudo apt-get install gcc parted pythonx.x-dev libmysqlclient-dev

  2. Shell

     • emacs, zsh :

         sudo apt-get install emacs zsh

     • oh-my-zsh :

         sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

     • zsh-autosuggestions :

         git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions

     • zsh-syntax-highlighting :

         git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting

     • Aliases :

         echo -e "\nalias ne=\"emacs -nw\"\nalias createenv=\"virtualenv -p python3 .env\"\nalias startenv=\"source .env/bin/activate\"\nalias stopenv=\"deactivate\"\nalias restartserver=\"sudo systemctl restart nginx.service apache2.service\"\nalias django=\"python manage.py\"\n" >> .zshrc

• Nginx - Allow custom client max body size (Guide Source)

  1. Add the following lines to the /usr/local/psa/admin/conf/panel.ini

      [webserver]
      nginxClientMaxBodySize =

     ⚠️ If the panel.ini file does not exist, create it using sample file:

      $ cp /usr/local/psa/admin/panel.ini.sample /usr/local/psa/admin/panel.ini

     Make sure that permissions of the file /usr/local/psa/admin/conf/panel.ini are correct:

      $ ls -la /usr/local/psa/admin/conf/panel.ini

     -rw-r--r-- 1 root root 1857 Nov 26 11:03 /usr/local/psa/admin/conf/panel.ini

  2. Regenerate nginx & apache configuration files for all vhosts to apply changes

      $ plesk sbin httpdmng --reconfigure-all

  3. Restart nginx

      $ sudo systemctl restart nginx

• Storage

  1. Créer et configurer un disque supplementaire sur une instance
  2. Augmenter la taille d’un disque supplementaire / Partition et augmentation taille disque supplémentaire

Plesk

• Move vhost folder

  /usr/local/psa/bin/transvhosts.pl --dest-dir /newfolder --correct-scripts

• mod_wsgi

  sudo apt install libapache2-mod-wsgi-py3
