Копирование Fedora, CentOS, RedHat на VMware

ОКРУЖЕНИЕ: VMware ESXi 5.1, CentOS 6, RedHat 6, Fedora 19
ЦЕЛЬ: Подготовить виртуальную машину для копирования или клонирования с VMware ESXi на VMware ESXi .
ПРОБЛЕМА: Не работает сеть после копирования или клонирования
РЕШЕНИЕ:

# Выполняется от пользователя root
# Скопировать конфигурционные файлы в домашнюю директорию
yes | cp -f /etc/udev/rules.d/70-persistent-net.rules ~/.
yes | cp -f /etc/sysconfig/network-scripts/ifcfg-eth0 ~/.
# Изменить конфигурционные файлы
sed -i 's/^SUBSYSTEM/#SUBSYSTEM/g' /etc/udev/rules.d/70-persistent-net.rules
sed -i 's/^UUID/#UUID/g' /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i 's/^MACADDR/#MACADDR/g' /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i 's/^HWADDR/#HWADDR/g' /etc/sysconfig/network-scripts/ifcfg-eth0
# Почистить перед копированием
rm -rf $(find /tmp -type f)
rm -rf $(find /var/log -type f)
rm -rf $(find /home -type f -name ".bash_history")
rm -fr ~/.bash_history
# Выключить виртуальную машину
poweroff

Скоприровать или экспортировать виртуальную машину.
Восстановить конфигурционные файлы на мастере (если нужно):

yes | cp -f ~/70-persistent-net.rules /etc/udev/rules.d/
yes | cp -f ~/ifcfg-eth0 /etc/sysconfig/network-scripts/

Check on Nagios the latest files in folder with NSClient++ 0.3.9

CURRENT CONFIGURATION: Linux OpenSuSe, Nagios 3.2.3, NRPE; Windows 2003R2 x64 server, NSClient++ 0.3.9.330 2011-09-02

OBJECTIVE: Monitor MSSQL backup, IIS logs replication with Nagios. Check FOLDER with files (MSSQL backup, IIS logs, S3 logs, etc.). Send WARNING if files are older than some hours.

SOLUTION:
NRPE has to work on Nagios server and on Windows client computer with NSClient++.
Nagios server command.cfg file:

define command{
  command_name    check_nrpe_files_written
  command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c CheckFiles -a "path=$ARG1$" "pattern=$ARG2$" "filter=written gt -$ARG3$" truncate=4096 "master-syntax=files: %total%" max-dir-depth=$ARG4$ MinWarn=0
}

define command{
  command_name    check_nrpe_files_creation
  command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c CheckFiles -a "path=$ARG1$" "pattern=$ARG2$" "filter=creation gt -$ARG3$" truncate=4096 "master-syntax=files: %total%" max-dir-depth=$ARG4$ MinWarn=0
}

Nagios server somename.cfg file examples:

define service{
...
  check_command           check_nrpe_files_creation!F:\\Backup\\SERVER01\\mssql\\backup\\default\\full!*.bkz!30h!0
  normal_check_interval   720
}
define service{
...
  check_command           check_nrpe_files_creation!F:\\Backup\\SERVER06\\ServiceDesk\\backup!*.data!30h!0
  normal_check_interval   720
}
define service{
...
  check_command           check_nrpe_files_creation!F:\\backup\\SERVER01!*-exchange_1_storage_group.bkf!8d!0
  normal_check_interval   1440
}
define service{
...
  check_command           check_nrpe_files_written!D:\\Logs\\IISLogs!*WEB01*.log!6h!4
  normal_check_interval   180
}
define service{
...
  check_command           check_nrpe_files_written!D:\\Replica\\UploadCopy\\s3!LastReplication.log!30h!0
  normal_check_interval   720
}

CURRENT CONFIGURATION:  Windows 2008R2 SP1 instance on Amazon AWS VPC
OBJECTIVE: Time synchronise
ISSUE:
C:\>sc start w32time
[SC] StartService FAILED 1290:
The service start failed since one or more services in the same process have anincompatible service SID type setting. A service with restricted service SID type can only coexist in the same process with other services with a restricted SID type. If the service SID type for this service was just configured, the hosting process must be restarted in order to start this service.
C:\>sc start Ec2Config
[SC] StartService FAILED 1068:
The dependency service or group failed to start.
SOLUTION:
Uninstall Ec2ConfigService. Delete all in c:\Program Files\Amazon\Ec2ConfigService\ except  config files in c:\Program Files\Amazon\Ec2ConfigService\Settings\ .
Uninstall w32time by command

w32tm /unregister

Reboot server.
Install and start w32time service by command

w32tm /register

@ping localhost -n 5 >; nul

sc start w32time

Configure w32time service. Example:

w32tm /config /update /manualpeerlist:0.ie.pool.ntp.org,0.europe.pool.ntp.org,3.europe.pool.ntp.org /syncfromflags:MANUAL

@ping localhost -n 2 >; nul

w32tm /monitor /computers:0.ie.pool.ntp.org

w32tm /resync

Reboot the server ant test w32time service. Example

w32tm /monitor /computers:0.ie.pool.ntp.org

w32tm /resync

w32tm /query /peers

w32tm /query /configuration
