So it appears you've focused on 'slow moodle'. Actually, we hope that our Moodle can support 900 students to undergo online exam at the same time. It appears that Moodle was overloaded when about 300 online students submitted answer *.jpg files to Moodle simultaneously within 15 minutes. How many concurrent users would Moodle support now? 400? 136? I wonder why some people set this value to 1000 or more. MaxRequestWorkers = Total avail mem * 80% / Max mem usage of apache processĭoes it mean that the default value of MaxRequestWorkers 400 is already large enough? The calculated value is only 136. The average apache process is using 286.77 MB of memory The smallest apache process is using 254.11 MB of memory The largest apache process is using 298.64 MB of memory httpd is currently using 111.26 MB of memory. Memcache Detected => Using 37.03 MB of memory Redis Detected => Using 45.51 MB of memory. MySQL Detected => Using 24252.97 MB of memory. Your PHP Memory Limit (Per-Process) is 512M. Your ThreadsPerChild setting for worker MPM is 25Ĭurrent Apache Process Count is 5, including the parent PID. I crop out some important points from the result of apache2buddy as follow: The apache2buddy works now! I found that apachectl is located in /usr/local/apache2/bin It works after I added this add directory to $PATH It looks like you might be running something else, other than apache. This script now requires apache2ctl to analyze Apache's vhost configurations. Unable to locate the apache2ctl utility.

How can I know what the parameter values should be if I fail to do the tuning analysis with bin]# whereis nano I think our Linux is CentOS 7.4 may not support the command 'apachectl'. MaxRequestWorkers (or, MaxClients? I'm not sure) Actually, I wonder in which config file these parameters should be located. I checked the file /usr/local/apache2/conf/nf and found that all the below parameters do not exist. Your ServerLimit setting for worker MPM is CONFIG NOT FOUND Your ThreadsPerChild setting for worker MPM is CONFIG NOT FOUND

The full path to the Apache config file is: /usr/local/apache2/conf/nf The process running on port 80 is Apache/2.4.29 (Unix) The process listening on port 80 is /usr/local/apache2/bin/httpd It seems that the tuning analysis is not successful. If I upload the file and run the below command, it only shows a little information and then shows some error. This tutorial helps you to increase request timeout in NGINX web server.When I run the below command, the apach2buddy shows the message 'Unable to locate the apache2ctl utility' and cannot continue the analysis. sudo systemctl restart nginxĪll done, With the above changes, you have successfully increased the request timeout in NGINX server.

The systems running with Systemd can use the following command. Edit the specific server block configuration file and add the following settings:Īfter making the changes, you must restart the NGINX service to apply changes. In case, you just want to increase request timeout for a specific server or subdomain, then add the directives for its server block only. To make changes for all servers, edit the NGINX main configuration file and add the following content under http block. Here the http block allows the changes in all server in NGINX. Then you need to add proxy_read_timeout, proxy_connect_timeout, proxy_send_timeout directives to http or server block. Increase Request Timeout in NGINXįor example, you want to increase request timeout to 300 seconds. In this quick FAQ, you will learn to change the request timeout in NGINX web server.
