nginx + spawn-fcgi is serving raw cgi (binary) file content (not executing them) -


i'm stumped trying figure out why nginx + spawn-fastcgi serving raw binary content instead of executing them , serving result.

the goal configure nagios core 4.x using nginx. there many great blogs on this; none have shed light on problem.

i'm using centos 6.6 nginx v1.0.15, spawn-fcgi v1.6.3, , php (php-fpm) v5.4.30.

the php file hosting works great (php-fpm), **it's spawn-fcgi content i'm having issue charge of serving /cgi-bin/*.cgi files. here spwn-fcgi environment:

cat << _eof > /etc/sysconfig/spawn-fcgi options="-u apache -g apache -a 127.0.0.1 -p 9001 -c 32 -f 1 -p /var/run/spawn-fcgi.pid -- /usr/bin/php-cgi" _eof

my nginx configuration:

server {    listen 80;    server_name monitor.mydomain.com;    return 301 https://$server_name$request_uri; }  server {    listen 443;     # satisfy allows bypass authentication    # allowed ip addresses    satisfy any;    # local traffic    allow   192.168.0.0/24;    allow   127.0.0.0/8;    # drop rest of world    deny    all;     server_name monitor.mydomain.com;    root /usr/share/nagios;     ssl_session_timeout  5m;    ssl_protocols tlsv1 tlsv1.1 tlsv1.2;    ssl_ciphers 'ecdhe-rsa-aes128-gcm-sha256:ecdhe-ecdsa-aes128-gcm-sha256:ecdhe-rsa-aes256-gcm-sha384:ecdhe-ecdsa-aes256-gcm-sha384:dhe-rsa-aes128-gcm-sha256:dhe-dss-aes128-gcm-sha256:kedh+aesgcm:ecdhe-rsa-aes128-sha256:ecdhe-ecdsa-aes128-sha256:ecdhe-rsa-aes128-sha:ecdhe-ecdsa-aes128-sha:ecdhe-rsa-aes256-sha384:ecdhe-ecdsa-aes256-sha384:ecdhe-rsa-aes256-sha:ecdhe-ecdsa-aes256-sha:dhe-rsa-aes128-sha256:dhe-rsa-aes128-sha:dhe-dss-aes128-sha256:dhe-rsa-aes256-sha256:dhe-dss-aes256-sha:dhe-rsa-aes256-sha:aes128-gcm-sha256:aes256-gcm-sha384:aes128:aes256:aes:des-cbc3-sha:high:!anull:!enull:!export:!des:!rc4:!md5:!psk';    ssl_prefer_server_ciphers on;    ssl_session_cache  builtin:1000  shared:ssl:10m;     ssl on;    ssl_certificate      /etc/pki/tls/certs/mydomain.com.crt;    ssl_certificate_key  /etc/pki/tls/private/mydomain.com.key;     index  index.php index.html index.htm;     access_log  /var/log/nginx/nagios.access.log;    error_log /var/log/nginx/nagios.error.log;     # security    auth_basic            "restricted area";    auth_basic_user_file  mynagios.htpasswd;     location ~ \.htaccess {       deny all;    }     location / {        if ($uri ~* "\.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$") {          expires max;          break;       }    }     error_page  404              /404.html;    location = /404.html {       root   /usr/share/nginx/html;    }     # redirect server error pages static page /50x.html    #    error_page   500 502 503 504  /50x.html;    location = /50x.html {       root   /usr/share/nginx/html;    }     # pass php scripts fastcgi server listening on 127.0.0.1:9000    #    location ~ \.php$ {       try_files $uri = 404;        fastcgi_split_path_info ^(.+\.php)(/.+)$;       fastcgi_pass   127.0.0.1:9000;       fastcgi_index  index.php;       fastcgi_param  script_filename  $document_root$fastcgi_script_name;       include        fastcgi_params;    }     #location ~ \.cgi$ {    location /nagios/cgi-bin/ {       root   /usr/lib64/nagios/cgi;       rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;        fastcgi_param  auth_user $remote_user;       fastcgi_param  remote_user $remote_user;       fastcgi_param  script_filename  $document_root$fastcgi_script_name;       #fastcgi_pass unix:/var/run/php-fcgi.sock;       fastcgi_pass   127.0.0.1:9001;       include      fastcgi_params;    } }

the tool in question running:

[root@fserver conf.d]# netstat -pnat | egrep '900(0|1)' tcp        0      0 127.0.0.1:9000              0.0.0.0:*                   listen      9054/php-fpm         tcp        0      0 127.0.0.1:9001              0.0.0.0:*                   listen      28888/php-cgi

again, in nutshell; config 'almost' working well, request https://monitor.mydomain.com/nagios/cgi-bin/status.cgi servers content:

elf>... <raw ugly content>

it's worth noting was using selinux (wrote own module nagios), have disabled (all of selinux) until can resolved cgi issue.

any advice guys can provide fantastic! tia

i figured issue out; should have same problem did, result of not using fcgiwrap. followed instructions , compiled it.

using fcgiwrap allowed me execute code spawn-fcgi returned instead of displaying raw data (my problem):

cat << _eof > /etc/sysconfig/spawn-fcgi options="-u apache -g apache -a 127.0.0.1 -p 9001 -f /usr/sbin/fcgiwrap -p /var/run/spawn-fcgi.pid" _eof  # restart spawn-fcgi service spawn-fcgi restart

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...
