This morning I'm getting 502 Bad Gateway on my server. My Setup: CentOS Version: CentOS 7 64bit ? Centmin Mod Version Installed: 123.09beta01 Nginx Version Installed: i.e. 1.11.12 PHP Version Installed: 7.0.15 MariaDB MySQL Version Installed: 10.1.22 When was last time updated Centmin Mod code base ? : today NGINX log: Code: [error] 1052#1052: *5 connect() failed (111: Connection refused) while connecting to upstream, client: ***.87.161.***, server: *****.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.*****.com" Tried to restart PHP-fmp: Code: # bash -x /etc/init.d/php-fpm restart + '[' -f /proc/user_beancounters ']' + '[' '!' -d /var/run/php-fpm ']' + prefix=/usr/local + exec_prefix=/usr/local + php_fpm_BIN=/usr/local/sbin/php-fpm + php_fpm_CONF=/usr/local/etc/php-fpm.conf + php_fpm_PID=/var/run/php-fpm/php-fpm.pid + php_opts='--fpm-config /usr/local/etc/php-fpm.conf' ++ cat /var/run/php-fpm/php-fpm.pid + kill -0 + running=1 + case "$1" in + /etc/init.d/php-fpm stop Gracefully shutting down php-fpm kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] ................................... failed.

Method of install ? Via centmin.sh menu option 1, Git install or curl one liner install as outlined at Centmin Mod LEMP Stack Install Nginx on CentOS ? Or which 123.09beta01 installer did you choose to use at https://community.centminmod.com/threads/centmin-mod-09-beta-branch-testing.4128/ ? The standard betainstaller.sh or betainstaller7.sh for PHP 7 default or betainstaller-latest.sh ? You used standard betainstaller.sh and then used centmin.sh menu option 5 to upgrade to PHP 7.0.15 ? What type of cpu is on your server ? You can find out by posting output for command Code (Text): cat /proc/cpuinfo I ask as the illegal instruction error is a clue as similar to https://community.centminmod.com/posts/45122/ and https://community.centminmod.com/posts/23675/ Code (Text): Starting php-fpm /etc/init.d/php-fpm: line 76: 3526 Illegal instruction $php_fpm_BIN $php_opts failed It's when you use betainstaller-latest.sh (which enables GCCINTEL_PHP='y') or manually enable GCCINTEL_PHP='y' in /etc/centminmod/custom_config.inc as GCCINTEL_PHP='y' enables GCC intel optimised compile options for PHP install but this could cause problems on very very old Intel cpus and I thought I accounted for them all with fix at https://community.centminmod.com/threads/update-inc-php_configure-inc.5596/. Edit: okay i actually made GCCINTEL_PHP='y' the default in 123.09beta01 now so that might explain it. Will confirm when i find out your /proc/cpuinfo output from above cat command. If you do have in enabled GCCINTEL_PHP='y' in /etc/centminmod/custom_config.inc, you can disable it via removing entry or setting it to GCCINTEL_PHP='n', then re-run centmin.sh menu option 5 and upgrade to PHP 7.0.17 which is latest and that should disable the Intel optimised GCC compiler options.
that could be a separate issue altogether If on Centmin Mod 123.09beta01, you may have ran into the new tools/autoprotect.sh cronjob feature outlined at Beta Branch - autoprotect.sh - apache .htaccess check & migration to nginx deny all | Centmin Mod Community You uploaded scripts may have .htaccess deny from all type files in their directories which may need bypassing autoprotect. It's a security feature that no other nginx based stack has as far as I know So instead, all .htaccess 'deny from all' detected directories now get auto generated Nginx equivalent location match and deny all setups except if you want to manually bypass the directory from auto protection via a .autoprotect-bypass file - details below here. You can read a few threads below on how autoprotect.sh may have caught some folks web apps falsely and the workarounds or improvements made to autoprotect.sh with the help of users feedback and troubleshooting. Is it better to add an exeption for 127.0.0.1 for autoprotect rules? | Centmin Mod Community IP.Board - Query on autoprotect + IPB forums | Centmin Mod Community Wordpress - Akismet JS and CSS - Forbidden? | Centmin Mod Community https://community.centminmod.com/posts/45782/
i actually set GCCINTEL_PHP to default to enable now, so to disable create persistent config file at /etc/centminmod/custom_config.inc and set in it Code (Text): GCCINTEL_PHP='n' then recompile php via centmin.sh menu option 5 for PHP 7.0.17
I had this server running from September with PHP 7 and centminmod one liner install for centminmod I honestly don't recall if I installed php5 and then upgraded to php7 or I installed php7 from the beginning CPU: Code: # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel Xeon E312xx (Sandy Bridge) stepping : 1 microcode : 0x1 cpu MHz : 2399.998 cache size : 4096 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc rep_good nopl eagerfpu pni pclmulqdq ssse3 cx16 pcid sse4_1 sse4_2 x2apic popcn t tsc_deadline_timer aes xsave avx hypervisor lahf_lm xsaveopt bogomips : 4799.99 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel Xeon E312xx (Sandy Bridge) stepping : 1 microcode : 0x1 cpu MHz : 2399.998 cache size : 4096 KB physical id : 1 siblings : 1 core id : 0 cpu cores : 1 apicid : 1 initial apicid : 1 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc rep_good nopl eagerfpu pni pclmulqdq ssse3 cx16 pcid sse4_1 sse4_2 x2apic popcn t tsc_deadline_timer aes xsave avx hypervisor lahf_lm xsaveopt bogomips : 4799.99 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management: I can be wrong but I think this is related issues.
ah then could be a different reason then. Since you had it installed for that long, make sure to update Centmin Mod 123.09beta01 branch code via centmin.sh menu option 23 submenu option 2 to be on latest code before just trying centmin.sh menu option 5 to update to PHP 7.0.17 as that is latest and had bug fixes since 7.0.16 https://community.centminmod.com/threads/php-7-0-16-is-available.10462/ and 7.0.17 https://community.centminmod.com/threads/php-7-0-17-is-available.10778/ Upgrading Centmin Mod Code to Latest Version Getting Started Guide step 19 outlines also how to keep Centmin Mod code updated or how to switch version branches.
