raspberry pi - mySQL InnoDB tables damaged after clean system restart -

-

i have problem small (it's raspberry pi) mysql installation. point it's sure innodb system files corrupted/damaged after system (debian linux like) reboot or halt.

logs show innodb engine shotdown mysql not start after because of damaged innodb files.

just explain, raspberry pi small computer running debian linux. file system sd card based.

hardware small use collect real world sensors data, it's not unusual have dozen of thousands rows in main table.

i asked question on rpi forum seems need more experienced mysql people solve :)

i did 2 things , appears have helped:

  • made sure debian-sys-maint user still there server shut down:

    grant privileges on *.* 'debian-sys-maint'@'localhost' identified '[password /etc/mysql/debian.cnf]' grant option; flush privileges;

  • then, added sync in /etc/init.d/mysql script in stop case before ;

i had problem after complete reimage (due power failure corrupting filesystem) , it's behaving 'sync'. (shouldn't need that, hey helps)

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
