The script can also be used to recover from a catastrophic loss or coruption of the cpanel-perl packages blocking check_cpanel_pkgs or upcp to recover the system. This script is automatically invoked if needed when check_cpanel_pkgs cannot run. =head1 NOTE The list of Perl packages install by this script should be short. This script should only use default perl packages install with the system, no Cpanel packages can be use as part of this script. =cut my %shared_install_env = ( LANG => 'C', LANGUAGE => 'C', LC_ALL => 'C', LC_MESSAGES => 'C', LC_CTYPE => 'C', ); our %DISTRO_SETUP = ( 'centos' => { name => 'centos', install_env => { %shared_install_env, }, install_cmd => [ '/bin/rpm', '-Uvh', '--force', '--nodeps' ], template => { base_url => 'http://%httpupdate%/RPM/%cpanel_major%/%distro_name%/%distro_major%/x86_64', file_name => '%package%-%version%~el%distro_major%.%arch%.rpm' }, package_sha512 => 'rpm.sha512', # could use later once pushed to prod sha512 }, 'ubuntu' => { name => 'ubuntu', install_env => { %shared_install_env, DEBIAN_FRONTEND => q[noninteractive], DEBIAN_PRIORITY => q[critical], }, install_cmd => [ '/bin/dpkg', '-i', '--force-confnew' ], template => { base_url => 'http://%httpupdate%/ubuntu/pool', base_file_uri => '%package%', file_name => '%package%_%version%~u%distro_major%_%arch%.deb', }, package_sha512 => 'sha512', }, ); our $CPANEL_CONFIG_FILE = '/var/cpanel/cpanel.config'; our $SIG_VALIDATION_CPCONF_KEY = 'signature_validation'; sub colorize_bold { my ( $color, $msg ) = @_; return $msg if !defined $color || -e '/var/cpanel/disable_cpanel_terminal_colors'; $msg ||= ''; return chr(27) .
