Example Error message:

PHP Fatal error: 
The encoded file /usr/local/cwpsrv/htdocs/resources/admin/include/cron.php has expired.
 in Unknown on line 0

The solution is to manually update CWP from the bash shell.

cd /usr/local/cwpsrv/htdocs
chattr -i -R /usr/local/cwpsrv/htdocs/admin
wget static.cdn-cwp.com/files/cwp/el7/cwp-el7-0.9.8.1160.zip
unzip -o -q cwp-el7-0.9.8.1160.zip
rm -f cwp-el7-0.9.8.1160.zip

cd /usr/local/cwpsrv/var/services/
wget static.cdn-cwp.com/files/cwp/el7/cwp-services.zip
unzip -o -q cwp-services.zip
rm -f cwp-services.zip

Don't forget to change the version from this example 0.9.8.1160 to the latest version which you can find on this link:

- CentOS 8 till the end of 2021
- CentOS 7 till June of 2024
- CentOS 8 Stream will be only supported as an upstream version
- CWP-CentOS 8 Stream-Delayed delayed version of CentOS 8 Stream (it has a delay of 14-60 days)

Video info

Other supported Linux distributions:
- RockyLinux Minimal
- AlmaLinux Minimal
- Oracle Linux
- RedHat Linux

Recommended version:
- CentOS 7 Minimal

We have custom delayed repositories of the CentOS Stream which allow us to make the CentOS Stream a stable version.
Using our repositories gives you an additional stability level because delaying the repository from the official CentOS 8 Stream allows us to keep track of the possible issues which could be caused by some updated packages or dependencies.

We already have in the production CWP-CentOS 8 Stream-Delayed and we keep all CentOS 8 Stream repositories up to 2 months old:
- latest (default CentOS Stream repository)
- stable (from CWP repository)

You can switch your server from CentOS 8 Stream to CWP-CentOS 8 Stream-Delayed by running this command on your cwp server

sh /scripts/el8_stream_convert_to_cwp_stable

* This would remove CentOS 8 Stream repositories and install CWP-CentOS 8 Stream-Delayed repositories.

FAQ:
- There is no any downtime
- Single command fast server switch

Many people are scared about the CentOS 8 Stream but we see this as an opportunity to provide the latest new features to all our clients and with our custom repositories we can also guarantee stability.

There is also some news about additional new Linux branches coming from CentOS, we will probably support the best of them.
Some already announced coming soon are CloudLinux OS and Rocky Linux.

Please note that currently we still recommend CentOS 7 as the best version to get installed as it also provides our CWP Secure Kernel which is very important for server security and especially for shared web hosting servers.
http://wiki.centos-webpanel.com/cwp-secure-centos-kernel

The script format is bash.
Script name: /root/.cwp_autoupdate.sh
Script run command: sh /root/.cwp_autoupdate.sh

CWP will automatically detect if the file exists and run it.

This can be also used to replace logo or make your own custom branding changes to cwp user panel theme on each cwp update.

Example script to replace cwp logo:

#!/bin/bash
rm -f /usr/local/cwpsrv/var/services/users/cwp_theme/original/img/new_logo_small.png
cp /root/my/new_logo_small.png /usr/local/cwpsrv/var/services/users/cwp_theme/original/img/

High Performace WebServers Configuration
Welcome to new and advanced webservers configuration, we are now giving you the flexibility and performance unlike anything else.
- PHP-FPM Selector with the ability to run different version per domain or subdomain.
- PHP-FPM with additional cache options for best performances.
- Advanced WebServers, that allows you to run custom webservers with different setup per domain.

Let's start with the installation!

Install PHP-FPM (Not required)
– go to left menu: PHP Settings -> PHP-FPM Selector and install php-fpm version you want to use.
** wait for the installation to complete, note that each PHP version you select can take up to ~15minutes to build, you can also install additional versions later.

Select WebServers you want to use (Required, you can't skip this)
here you can rebuild your webservers system and choose which webservers you want to run.
– go to left menu: WebServer Settings -> Select WebServers and select the version that you want to use (after php-fpm install).
* We recommend the last option (Nginx & Varnish & Apache).

* You can also select here if you want to force all users to use php-fpm by default as currently, a default is still php-cgi with suphp like before.
* Please note that if you don't use "force php-fpm" then you can use all options from WebServers Domain Conf and enable php-fpm for domains you want.

Select Configuration for WebServers you want to use (Not required)
here you can select configuration and templates for vhosts of the webservers you have installed with Select WebServers.
– go to left menu: WebServers Configuration -> WebServers Main Conf to manage webservers configuration (this works only after new webservers are installed).

* New webservers installation will also rebuild all nginx/varnish/apache configuration.
* Note that now we have an independent php-cgi version with suphp from php-fpm so you can have them all configured differently.

WebServers Domain Conf (Not required)
- here you can make configuration per domain based on the Select WebServers installation, this means that each domain can run different webservers and vhost templates, example: domain1.com can run php-cgi/suphp while domain2.com can run php-fpm.

This command will show you all that will be updated and you will need to confirm that you want to proceed with the update

yum update --enablerepo=cwp --enablerepo=epel

This command will do the update without any questions

yum -y update --enablerepo=cwp --enablerepo=epel

Install repository having new kernels

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm
sed -i "s/enabled=1/enabled=0/g" /etc/yum.repos.d/elrepo.repo

To install kernel 4

yum --enablerepo=elrepo-kernel install kernel-ml  

To install kernel 3

yum --enablerepo=elrepo-kernel install kernel-lt  

Now lets activate our newly installed kernel.
Edit File /etc/grub.conf and set "default=" to your new kernel, this will be probably the 0.

You can count each line starting with kernel as one number starting from 0, so the first kernel will be 0 and others +1.
Latest installed kernel version starts from the top.

Example:
"kernel /vmlinuz-4.3.3-1.el6.elrepo.x86_64" will be default 0
"kernel /vmlinuz-2.6.32-573.12.1.el6.x86_64" will be default 1
"kernel /vmlinuz-2.6.32-504.el6.x86_64" will be default 2

Once you have changed the /etc/grub.conf kernel boot configuration, you need to reboot the server.
When server comes back, you can check the kernel version by using command:

uname -a

Please note that this custom kernel versions are NOT default in Centos 6 system and that this could cause some issues with the compatibility of server services.

If you have a VPS server like openVZ then you can't do a kernel update, that would need to be done by your server provider.

If you need a help, you can always check our support services.

If the new version is released then please allow up to 48 hours for your server to update.

You can check for the latest released version on our ChangeLog website
http://centos-webpanel.com/changelog

If you want to force update you can do that by executing the following command.

sh /usr/local/cwpsrv/htdocs/resources/scripts/update_cwp

or

sh /scripts/update_cwp

If you have issues with the CWP update then you should contact support.
