# Misc Issue

#### Low Ram

Enable 2GB swap , if you see the services are being killed 

    fallocate -l 2G /swapfile
    dd if=/dev/zero of=/swapfile bs=1M count=2048
    chmod 600 /swapfile
    mkswap /swapfile
    swapon /swapfile
    
Also make the number of child workes 2x the amout of RAM in www-data pool of php-fpm  .

#### Home Path 

To set home for user -
inside public_html create **.bash_profile**
inside the file put the home path as

    echo "export HOME='/srv/www/my.writetextfast.com/home/'" >> ~/home/bash_profile
    
#### Cleanup 

Find largest file -

	find -type f -exec du -Sh {} + | sort -rh | head -n 5
    
Cleanup snaps folder

	snap list --all | while read snapname ver rev trk pub notes; do if [[ $notes = *disabled* ]]; then snap remove "$snapname" --revision="$rev"; fi; done
    
Resize allocated disk

	tune2fs -m1 /dev/sda
    
Optimize images 

    find . -type f -iname "*.jpg" -exec jpegoptim --max=85 --strip-all --all-progressive --preserve-perms -p {} +
    
#### Clear comments

	// Delete comments
	wp comment delete $(wp comment list --status=spam --format=ids) --force
    
    // Delete Pending
    wp comment delete $(wp comment list --status=hold --format=ids) --force
    
#### No log but critial 

Create a debug backtrace in mu-plugins , this will dump all messages -

    add_filter(
    'wp_php_error_message',
    function( $message, $error ) {
            debug_print_backtrace();
            return $message;
    },
    10,
    2
    );
    
#### IPTables Dumpe

If you wish to reset ip tables to default. [Stackhttps://serverfault.com/a/1042478]

    iptables -P INPUT ACCEPT
    iptables -P OUTPUT ACCEPT
    iptables -P FORWARD ACCEPT
    #Then flush the rules:
    iptables -F INPUT
    iptables -F OUTPUT
    iptables -F FORWARD
    
#### Random dump 

If you wisht o find where files are outputting code

    $locations = [];
    ob_start(function($buffer) {
      global $locations;
      $locations[] = debug_backtrace();
      return $buffer;
    }, 1);

    -- code --
    
    print_r($locations);
