Cpanel Logs

Applications can log the system activity in two ways, one being according to their autonomous logic & the other through the system’s 
log daemon, well know as syslog..

The syslog daemon’s configuration file /etc/syslog.conf contains all the necessary paths/locations as to where the logs are stored.

Usually the directory /var/log/ is used for the system logs but other applications use the applications specified directories to 
store their log files… Many distributions provide tools to manage and analyze the system logs.

Logrotate is a well known log rotation tool which usually is configured in the /etc/logrotate.conf file.
It may also have additional package-defined configurations in the /etc/logrotate.d/ directory..In order to understand what’s 
happening on the system a brief analysis of /etc/syslog.conf is mandatory for checking the main logs 
positions.

How to reset default SSH port on cPanel servers

How to reset default SSH port on cPanel servers

Did you forget SSH port and try to reset it via WHM, Use the following SSH configuration settings on WHM.

Login to your WHM on a non secure port that is : 2086
For example : http://serverip:2086

Then browse the URL to reset the SSH configuration settings :

http://serverip:2086/scripts2/doautofixer?autofix=safesshrestart

After running the script, the default port 22 will reset on your cpanel SSH configuration. You can login SSH and reset it.

 

How to change the SSH port on cPanel Servers?
To change the SSH port on cPanel server. Login via root password and edit the following file.

vi /etc/ssh/sshd_config

Find the line that says Port 22 and change 22 to any number between 1024->65535 and save the file.

Once done, run:

/etc/init.d/sshd restart

Don’t forget to Enable SSH port on your server Firewall (CSF,etc.,). Otherwise you won’t connect SSH.

Add the new ssh port on csf firewall settings..

vi /etc/csf/csf.conf

 

TCP_IN =

TCP_OUT =

 

APF install

cd /usr/local/src/
wget http://www.rfxnetworks.com/downloads/apf-current.tar.gz
tar -zxvf apf-current.tar.gz; cd apf-*

You will get the following error when you try to restart/start apf every time.

apf(660): {glob} !!DEVELOPMENT MODE ENABLED!! – firewall will flush every 5 minutes.

This is because of the development mode enabled in APF configuration file. You can disable it by editing the configuration file.
Details from APF configuration file regarding development mode:

# !!! Do not leave set to (1) !!!
# When set to enabled; 5 minute cronjob is set to stop the firewall. Set
# this off (0) when firewall is determined to be operating as desired.
DEVEL_MODE=”1″

Edit the configuration file and set DEVEL_MODE=”0″, then restart APF using the command “apf -r“.

Cpanel Server Main IP Change

This KB describes on How to change a Cpanel servers main IP.

 

Make sure to take a backup of all the files mentioned in this KB.

 

1: edit /etc/sysconfig/network-scripts/ifcfg-eth0 and replace old server IP with new IP  // assuming eth0 as the primary Device

2: connect the server with LAN IP or IP-KVM

3: restart eth0 device

>> ifdown eth0

>> ifup eth0

 

3: Edit the following files

>>  /var/cpanel/mainip   //replace old IP with new  IP

>> /etc/ips    //replace new IP with old server main IP

>> /etc/hosts      //replace old IP with new  IP

4: update Cpanel  licence

>> /usr/local/cpanel/cpkeyclt

5: Ran the following script to update domains IP’s

>> for i in `cat /etc/trueuserdomains |cut -d: -f2`; do /usr/local/cpanel/bin/setsiteip -u $i newIP; done    // assuming all domains using the same shared IP’s

How to Distribute EasyApache Files Over Multiple Servers

Overview

You can move EasyApache profiles between servers.

Profile are located in the /var/cpanel/easy/apache/profile/custom directory. The filename will be identical to the name with which you save it, plus the .yaml file extension.

After you finish a profile’s configuration, you can move it to the /var/cpanel/easy/apache/profile/custom directory on the destination server.

You can use any available data transfer protocols that you have available.  These protocols include the following:

  • SCP
  • FTP
  • SFTP
  • rsync

Example

For example, the following steps demonstrate how to move a profile called myprofile.yaml with scp:

  1. Run the following command at the command line as the root user:
    1
    scp /var/cpanel/easy/apache/profile/custom/myprofile.yaml !root@$IP:/var/cpanel/easy/apache/profile/custom/myprofile.yaml

    Note:

     Replace $IP with the IP address of the machine to which you wish to connect

  2. If you choose not to use key authentication, enter the password when you are prompted.
    • The file will transfer to the /var/cpanel/easy/apache/profile/custom directory on the destination server.
  3. Run the following command on the new server:
    1
    /scripts/easyapache --build --profile=myprofile

Remember:

  • You may also copy raw opts (custom configure flags) and environment variables with the same method and transfer them to the appropriate directory on the new server.
  • You will also need to transfer the Apache profile’s preferences file (/var/cpanel/easy/apache/prefs.yaml) to the remote server.

Cpanel Individual Domain zone reloading

The restart of the entire named service for just reloading a domain zone would consume a lot of time. So it is just better to reload the individual zone file by using the following command.

# rndc reload domain IN internal

# rndc reload domain IN external

 

The command is case sensitive. So please take a look onto that uppercase “IN” in the command
