Hi Dear All, I am new to Linux server management. My server is a dedicated linux based server with CentOS 6.2 (Final) plesk version is 11.5.30. My server's health report always keeps a red signal from the last two months that apache cpu usage is too high. It usage remains approximately at about 40% to 60%. Server is not performing well . Although i have scanned through malware detection all of my sites on this server nothing found, cpu usage not getting down. Please have a look at the attached pic that i took after giving "top" command through putty which shows the top processes running on my server. Please please help me in this regard, what is going wrong with my server. What should i do , please someone tell me step by step.
The host command is quite unusual, check with: ps aux which process ID this command has and then search with: lsof | grep PROCESSID (Replace PROCESSID with the ID of this process) what this host process is doing.
Thanks for the reply. I just used the command ps aux and got process ID (32652) from there and issued second command lsof | grep 32652 Please find the attached screenshot. This process is taking 149% of cpu usage as shown in command (ps aux). /var/www/vhosts/jadoreestore.com/httpdocs/wp-content/plugins/ , plugins folder had 777 permissions now i have changed it to 755 although and deleted unnecessary files there. But cpu usage still not decreased.
Hello, I will suggest you please scan your server with maldet and removed all infected files from your account. Also secure your wordpres site using some wordpress pugins. And update your word-press core files and plugins to latest stable version so that you will not get any issues on your site.
