Hi everyone, I just made a clean install following this tutorial step by step: http://www.howtoforge.com/perfect-s...2-php-mysql-pureftpd-bind-dovecot-ispconfig-3 But my ispconfig is just giving me a HTTP 500. see here: https://92.51.132.136:8080/ my apache error.log shows: Code: Tue Sep 23 12:21:18 2014 (30945): Fatal Error Unable to allocate shared memory segment of 67108864 bytes: mmap: Cannot allocate memory (12) [Tue Sep 23 12:21:18.424304 2014] [fcgid:warn] [pid 29892] (104)Connection reset by peer: [client 81.217.14.40:51471] mod_fcgid: error reading data from FastCGI server [Tue Sep 23 12:21:18.424344 2014] [core:error] [pid 29892] [client 81.217.14.40:51471] End of script output before headers: index.php If searched the forums here and it seems that also some other people run into that problem but weren't able to solve it as well. Any ideas?
Code: root@lvps92-51-132-136:/etc/php5/cgi# free total used free shared buffers cached Mem: 4194304 1563328 2630976 205144 0 949312 -/+ buffers/cache: 614016 3580288 Swap: 3145728 0 3145728 Can't be. Is there any other setting to tune (eg in the mod_fcgid)? I also raised the memory_limit in the php.ini which showed no impact at all.
I solved this issue temporally with switching to mod_php instead of mod_fcgid. For anyone out there with the same problem, here is how to do that: Change in the /etc/apache2/sites-available/ispconfig.vhost Code: # <IfModule mod_fcgid.c> # DocumentRoot /var/www/ispconfig/ # SuexecUserGroup ispconfig ispconfig # FcgidIOTimeout 700 # FcgidBusyTimeout 3600 # <Directory /var/www/ispconfig/> # Options -Indexes +FollowSymLinks +MultiViews +ExecCGI # AllowOverride AuthConfig Indexes Limit Options FileInfo # <FilesMatch "\.php$"> # SetHandler fcgid-script # </FilesMatch> # FCGIWrapper /var/www/php-fcgi-scripts/ispconfig/.php-fcgi-starter .php # Require all granted # </Directory> # IPCCommTimeout 7200 # MaxRequestLen 15728640 # </IfModule> <IfModule mod_php5.c> DocumentRoot /var/www/ispconfig/ AddType application/x-httpd-php .php <Directory /var/www/ispconfig/> # php_admin_value open_basedir "/usr/local/ispconfig/interface:/usr/share$ Options FollowSymLinks AllowOverride None Order allow,deny Allow from all php_value magic_quotes_gpc 0 </Directory> </IfModule> Then there will be another issue that the config file which won't be found. You just need to set the permissions to Code: chmod 660 /usr/local/ispconfig/interface/lib/config.inc.php
I hope your server is not connected to the internet and does not host any client sites ayou change allows everyone with access to a site to take over your whole server.
Yeah, i know it's an insecure solution. I will just do my configuration in the backend and immediately put it down again. And yes, it is a virtual server.
Please post the output of: cat /proc/user_beancounters This wont help you. The problem is not in the ispconfig backend. The problem is that when the apache user can read the config.inc.php from ispconfig, then other websites on your server can read it as well and use the details to access the ispconfig mysql database.
here's the output: Code: root@lvps92-51-132-136:/usr/local/ispconfig/interface/lib# cat /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt 109003: kmemsize 26932600 28737536 134217728 144217728 0 lockedpages 0 0 2059 2059 0 privvmpages 391254 394235 943718 1048576 0 shmpages 50265 50265 65536 65536 229 dummy 0 0 9223372036854775807 9223372036854775807 0 numproc 106 159 500 500 0 physpages 291469 298542 943718 1048576 0 vmguarpages 0 0 524288 9223372036854775807 0 oomguarpages 126824 126824 524288 9223372036854775807 0 numtcpsock 29 29 550 550 0 numflock 7 8 1000 1100 0 numpty 3 3 102 102 0 numsiginfo 0 39 1024 1024 0 tcpsndbuf 516792 516792 5280000 7392000 0 tcprcvbuf 475136 475136 5280000 7392000 0 othersockbuf 136408 136408 3840000 5376000 0 dgramrcvbuf 0 2312 3584000 3584000 0 numothersock 86 86 550 550 0 dcachesize 12059763 12257915 14495514 16106127 0 numfile 1397 1500 17600 17600 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 numiptent 40 40 9223372036854775807 9223372036854775807 0
Take a look at the last column: failcnt. This is the counter how often you reached a limit in your vm and shmpages is one of the RAM memory limits. So even if free shows you free memory, there is indeed not enough RAM and therefor php failed. you can tune the parameters of a vm s that commands like free show up a lot of memory but you use one of the other parameters to set a lower limit so you can put more virtual machines on the server.
So i hope its not too late to ask in this thread. So i have the same issue and my server should have enough ram to do ispconfig 2048 MB. I tried out some values at /etc/php5/mods-available/opcache.ini. I have set the opcache.memory_consumption to 64 (basic) 32 and last 16, with 16 all is working but. i get now the errors Code: Mon Aug 10 21:01:38 2015 (7238): Fatal Error Unable to allocate shared memory segment of 16777216 bytes: mmap: Cannot allocate memory (12) [Mon Aug 10 xx:xx:xx.xxxxx 2015] [fcgid:warn] [pid 4246] (104)Connection reset by peer: [client xx.xxx.xx.xxx:xxxx] mod_fcgid: error reading data from FastCGI server, referer: https://xxxxxx.de:8080/index.php [Mon Aug 10 21:01:38.724213 2015] [core:error] [pid 4246] [client 62.134.43.70:48928] End of script output before headers: nav.php, referer: https://xxxxx.de:8080/index.php so what should i do to get rid of this error?
2048 MB "real" memory are enough, but you seem to be on a virtual server where shared memory is restricted and that causes this error. You can either disable opcache or you talk with your provider and ask them to increase the shared memory limit of your vm.
Perfect! Thank you very much its solved the problem. Hmm maybe i should switch to a dedicated machine for all others they are have the same issue. I have disabled opcache in /etc/php5/mods-available/opcache.ini with the line opcache.enable=0
so now i have ordered a new faster machine (virtual server) and the same issue is present. It seems to be that fast-cgi is the probleme on virtual hosts with shared memory. Is it possible to use only php-fpm in config or something?
When you have a virtual server where your ISP has disabled shared memory, then you cant use opcaches. It does not matter which php mode you are using. Either your ISP enables shared memory or don't install a php opcaching module.
