Error 2002 after changing datadir in mysql.cnf - Raspberry Pi Forums

-

hello, new raspberry , linux.
bought pi2 piface digital 2, no problems raspbian , mysql + php5 installs.

tried move newly created database nas (buffalo terastation); found lots of infos on net, mounted ok destination folder, copied db, , changed "datadir" in /etc/mysql/my.cnf file.
but: no way restart mysql, consistently following "error 2002 (hy000): can't connect local mysql server through socket '/var/run/mysqld/mysqld.sock' (2)".

fooled around lot different parameters, changed "bind-address" 0.0.0.0 or pi2 ip address, socket location (also in debian.cnf) etc.
tried install apparmor, problem still there. reversible though, return "datadir = /var/lib/mysql" starts working again.
way, "$ sudo service mysql restart" works, "$ sudo /etc/init.d/mysql stop" consistently fails.

appreciate help, issue drives me crazy !

you need move /var/mysql (including subdirectories) new device update /etc/mysql/my.cnf reflect new location. there's lots of meta-data tables created when start running mysql first time.

dear all, working on image processing using raspberry pi, have installed intex usb web camera on raspberry pi. have used basic python script of image processing https://www.cl.cam.ac.uk/projects/raspb ... first.html required libraries installed on raspberry pi. script code: import imgproc imgproc import * # open webcam take pictures camera = camera(160, 120) # open viewer window display images viewer = viewer(160, 120, "the first step") # take picture camera img = camera.grabimage() # display image in viewer viewer.displayimage(img) # iterate on each pixel in image x in range(0, img.width): for y in range(0, img.height): # value @ xth column , yth row, place intensities variables red, green, blue = img[x, y] # test find colour dominant if red > green , red > blue: # red dominant, set pixel red img[x, y] = 255, 0, 0 elif green > red , green > blue: img[x, y] = 0, 255, 0 else: # if red or gr...

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
