CSF Firewall / Re: /bin/bash^M: bad interpreter and iptables
« on: April 03, 2019, 08:03:49 PM »
try this command
Do you see any ^M on output near $ ($ is an end-of-line symbol)?
If so, in VIM, you need an extra command to force display ^M before opening file to edit - see https://superuser.com/questions/357760/vi-on-linux-show-m-line-endings-for-dos-format-files for details
Launch vim without filename to edit
in vim interface execute a command
then open file to edit
You should see any ^M if exist
Code: [Select]

^M is a DOS ‘Carriadge Return/Line Feed’ control symbol. Possibly, you are edit UNIX shell script using Windows editor (or copy-paste it from Windows), so ^M was appended to each string in script.
Use CentOS appropriate text editor to fix it. If you not familar with ‘vi’ or ‘nano’ editors, you can install ‘mc’ - Midnight Commander, which looks like as Norton Commander for DOS using shell command
yum install mc
then navigate to your script, open it for edit and you will see ^M at the end of strings. Remove it completely

CentOS-WebPanel GUI / SSL link on admin login page point on IP address instead hostname
« on: September 28, 2018, 02:14:09 PM »
"Click here for SSL login" in admin login window point to CWP Server IP instead hostname - https://192.168.200.172:2031/login/index.php?login=logout
I rebuilt CWP via 'change hostname' option, but this link was not updated.
Manually entered URL https://cwp.mydomainname.tld:2031 work properly.
CWP version: 0.9.8.740

CentOS-WebPanel Bugs / Incorrect owner/group and permissions for subdomain directory
« on: September 26, 2018, 08:18:05 AM »
CWP create folder for subdomain with incorrect owner/group and permissions (if subfolder created outside /home/user/public_html)
1. Add a subdomain and assign for it directory outside main domain public_html, for example /home/user/subdomain/public_html
2. Check owner/group and directory mode from shell or from File Manager
subdomain folder have root as owner:group and directory mode is 755 against 750 for main domain
I fixed this using root shell, but this is a bug for user.

I see a ^M after /bin/bash - did you copy/paste script from Windows machine?
Use CentOS editor ‘nano’ or ‘mcedit’ from ‘mc’ package to remove unwanted ^M (DOSCarrige Return)

MySQL / Re: /var/lib/mysql = du -sh = 175G / I want to clear them
« on: January 21, 2018, 08:48:00 PM »
you should connect to your SQL server using SQL root login,
then execute command in SQL console (172 was used as example)
then leave SQL console
If you disable binary logging, yes, you can delete this files with rm command when MySQL stopped
Code: [Select]
#mysql -u root -pthen execute command in SQL console (172 was used as example)
Code: [Select]
mysql>PURGE BINARY LOGS TO ‘mysql-bin.172’; then leave SQL console
Code: [Select]
mysql>exitIf you disable binary logging, yes, you can delete this files with rm command when MySQL stopped

You need to use phpMyAdmin or mysql console client to do this.
Don’t delete this files using OS shell!

« on: January 16, 2018, 08:42:05 AM »
Examine log files in /usr/local/apache/logs/
Open /usr/local/apache/conf.d/vhosts-ssl.conf and verify that parameters
SSLCertificateFile
SSLCertificateKeyFile
(optional) SSLCertificateChainFile
point to right files, files exist and accessible for Apache. Check your key/cert pair using https://www.sslshopper.com/certificate-key-matcher.html
