==== Sudo Group ==== 

In ''Ubuntu'', Login with ''root'' 

<code bash> 
  ssh root@your_server_ip 
</code> 

Add ''user'', usually first user is required to input during installation steps. 

<code bash> 
  adduser firstuser
</code> 

Add ''user'' in ''sudo'' group 

<code bash> 
  usermod -aG sudo firstuser
</code> 

---- 
==== sudo without typing password ==== 

<code bash> 
  sudo visudo 
</code> 

Add following line. 

<code ini> 
  #includedir /etc/sudoers.d
  username ALL=(ALL) NOPASSWD: ALL
</code> 

----
==== Network configuration ==== 

Install ''wpasupplicant'' for wireless connection. 

<code bash> 
  sudo apt install wpasupplicant 
</code> 

check network adapters with ''ifconfig'' and ''iwconfig'' -- need to install ''wireless-tools''. 
Edit ''/etc/netplan/01-something.yaml'' for ''networkd'' or ''Network-Manager'' 

<code yaml> 
network:
  ethernets:
    enp3s0:
      addresses: []
      dhcp4: true
      optional: true
      nameservers:
        search: [search.domain.ltd]
        addresses: [8.8.8.8,8.8.4.4]
  wifis:
    wlp2s0:
      addresses: []
      dhcp4: true
      optional: true
      nameservers:
        search: [search.domain.ltd]
        addresses: [1.1.1.1,1.0.0.1]
      access-points:
        ? "your ssid"

----
==== Manage connected WiFi SSID ==== 

in ''Network-Manager'' ''path'': ''**/etc/Network-Manager/system-connections**'' 

''edit'' or ''delete'' ''**SSID**'' named file(s). 

----
==== Compiling RTL8811AU wireless driver ==== 

''purge'' installed driver, which is not working correctly and ''compile'' new driver. 

<code bash> 
  sudo apt purge rtl8812au-dkms
  sudo apt install git
  git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
  cd rtl8812AU_8821AU_linux
  sudo make -f Makefile.dkms install 
  sudo modprobe rtl8812au
</code> 

''check'' driver is installed and recognized by system. 

<code bash> 
  modinfo rtl8812au | grep A811		// Linux kernel module 
  ifconfig    				// network adapters 
  iwconfig    				// wireless configuration 
</code> 





----
==== Disable sleep/suspend/hibernate ====

When a system goes to sleep, suspend or hibernate mode, response from machine is extremely slow or timed out. Soon after waking up, system responses quickly. To prevent this, 

<code bash> 
  sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
</code> 

Action to do next is [[deb_gilead#suspendtarget_is_masked|Suspend.target is masked]] 

---- 

==== Let's Encrypted ==== 

{{fa>certificate?color=#BBAA00}} [[:rpi_nimbus#let_s_encrypt|Let's Encrypt]] --- SSL/TLS certificates 

----
==== Install Nginx ==== 

<code bash> 
  sudo apt-get install nginx-extras     \\ heavier than other packages, full 
</code> 

---- 
==== Install MySQL ==== 

<code bash> 
  sudo apt-get install mysql-server 
  
  sudo mysql_secure_installation     \\ to secure MySQL weakness 
</code> 

{{fa>exclamation-triangle?color=#BBAA00}} without sudo, root authentication identified by temporary password is required. Never pass it. Do with ''sudo''
---- 
==== Install PHP ==== 

<code bash> 
  sudo apt-get install php-fpm php-mysql 
</code> 

Configure the PHP Processor

<code bash> 
  sudo vi /etc/php/7.x/fpm/php.ini 
</code> 

Comment out ''cgi.fix_pathinfo'' parameter and set value to ''0'' 

<code ini>
  cgi.fix_pathinfo=0
</code> 

And restart service. 

<code bash> 
  sudo systemctl restart php7.x-fpm 
</code> 

---- 
==== Nginx with PHP Processor ==== 

<accordion> <panel title="Default config of Nginx with PHP Processor">
<code nginx> 
server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;

    server_name server_domain_or_IP;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}
</code>
</panel> </accordion>

To use ''php-fpm'', need to edit ''/etc/php/7.x/fpm/pool.d/www.conf'' 

<code php> 
;listen = 127.0.0.1:9000 
listen = /run/php/php7.0-fpm.sock;  # which creates socket for php-fpm 

pm = dynamic
pm.max_children = ??
pm.start_servers = 8
pm.min_spare_servers = 4
pm.max_spare_servers = 8
pm.max_requests = 500
</code>

''pm.'' values could be changed according to resources such as physical memory and an average usage of each php processor. Guide for adjusting values are 

^ Setting Name  ^ Suggested value  ^
| ''max_children''  | (Total RAM - Memory used for Linux, DB, etc.) / process size  |
| ''start_servers''  | Number of CPU cores x 4  |
| ''min_spare_servers'' | Number of CPU cores x 2  |
| ''max_spare_servers'' | Same as start_servers  |
|  |  |

Available memory size can be guessed by commanding ''free -hl'' and process size used by ''php7.x-fpm'' is calculated by scripts [[https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py|ps_mem.py]] and ''sudo python ps_mem.py | grep php-fpm'' 

  12.9 MiB +  18.7 MiB =  31.6 MiB       php-fpm7.3 (4)

memory consumed by each php-fpm is assumed as ''31.6 Mbyte''.
