tomcat7 - Memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file -

-

situation: installed memcached on centos 5 (64 bit). ended installing php plugins using pecl, though they're unnecessary now.

problem:when execute 

/etc/init.d/memcached start

i following error:

starting memcached: memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: no such file or directory

but file libevent-2.0.so.5 present in /opt/couchbase/lib/.

should there in other folder ? how memcached start ?

/opt/couchbase/lib not set on system library path default. that's why unable find libevent when running /etc/init.d/memcached.

to solve can run command follows:

ld_library_path=/opt/couchbase/lib /etc/init.d/memcached

or solve on long term add following file (assuming using centos):

/etc/ld.so.conf.d/couchbase.conf

and in file add path "/opt/couchbase/lib". run ldconfig , re-run command start memcached.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
