PHP 5.5 5.6加速插件：Zend Opcache 大家知道目前PHP的缓存插件一般有三个： APC、 eAccelerator、 XCache，但未来它们可能都会消失，因为PHP 5.5已经集成 Zend Opcache，功能和前三者相似但又有少许不同，缓存速度据说比它们更快（注意：只是据说，我没测试过）。php5.5以后版本编译eAccelerator报错如下：eaccelerator.c:66:23: error: php_logos.h: No such file or directory究其原因是PHP5.5以下版本有php_logos.c，php_logos.h等文件。如果想在新版本继续用加速，目前知道是的php自带扩展 opcache。操作如下：cd /usr/local/src/php-5.6.0/ext/opcache/usr/local/webserver/php/bin/phpize./configure --with-php-config=/usr/local/webserver/php/bin/php-configmake && make install1234cd /usr/local/src/php-5.6.0/ext/opcache/usr/local/webserver/php/bin/phpize./configure --with-php-config=/usr/local/webserver/php/bin/php-configmake && make install最好修改/etc/php.ini在最后加入[opcache]zend_extension=/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20131226/opcache.so...

The P2V conversion of Debian OS is not as straight forward as CentOS where you just need to click Next, Next,...Finished!!!...The conversion process is same for both, but the Debian conversion may fail during the final stages of conversion.IssueWhile doing P2V on aDebian/Ubuntu OS, the process fails at 99%.Under log highlights, you could see the error"Error: Unable to reconfigure the destination virtual machine". Under the conversion status, you will find the error:FAILED: Anerror occurred during the conversion: 'GrubInstaller::InstallGrub:/usr/lib/vmware-converter/installGrub.sh failed with return code: 127, andmessage: Installing GRUB1 on (hd0)... /vmware-updateGrub.sh: 59: grub:not foundError installing GRUB Error running vmware-updateGrub.sh through chroot into/mnt/p2v-src-root ' If VMware conversionhas failed at 99%, that doesn't mean theconversion has failed completely. The copy of the physical machine will already be in thedestination when t...
How to P2V a Linux host in vSphere 4.0 Occasionally, you will need to P2V a physical Linux machine that doesn’t quite match up with the accepted configuration defaults for vSphere — particularly, a distribution (or even a fork of a distribution) that’s not 100% supported. For example, I recently had to P2V a CentOS 2.1 VM, which you would assume would appear to vSphere as a Red Hat Enterprise Linux 2.1 VM, seeing as the two distributions are binary-compatible. However, I assumed that, and it turned out I was wrong. :-)Given that CentOS is binary-compatible with RHEL, it’s very possible that you could simply edit /etc/redhat-release on the CentOS box to mirror what’s on a RHEL box and be done with it. (I haven’t tried, but if anyone wants me to, just holler.) Out of the box, because VMware Converter can’t figure out what distribution you’re using, it can’t/won’t/doesn’t install the correct drivers when you P2V your old, busted Linux host. So, when you boot up the VM, yo...
虚拟机在从物理 Red Hat 计算机转换后不引导 (2093497) Symptoms 免责声明：本文为 Virtual machine does not boot after being converted from a physical Red Hat machine (1002402) 的翻译版本。尽管我们会不断努力为本文提供最佳翻译版本，但本地化的内容可能会过时。有关最新内容，请参见英文版本。 Resolution 出现此问题的原因是，操作系统的 ramdisk 映像不包含适用于为虚拟机配置的虚拟 SCSI 适配器的驱动程序或模块。这些模块之所以不在 ramdisk 映像中，是因为该映像最初是在不使用此硬件的系统中创建的。必须将现有 ramdisk 映像替换为包含正确驱动程序的 ramdisk 映像。Converter 3.0.x 不支持 Linux 操作系统热克隆，也不支持对新虚拟硬件生成的虚拟机进行配置。仅支持不进行任何配置的冷克隆。而 vCenter Converter 4.0 支持某些 Linux 操作系统的热克隆和配置，包括 Red Hat。有关支持版本的列表，请参阅相关手册。验证下面每个故障排除步骤是否适合您的环境。每个步骤提供相关说明或文档链接，用于消除可能的原因和采取必要的补救措施。这些步骤按照最合适的顺序排序，以隔离问题并确定正确的解决方法。请勿跳过任何一个步骤。 注意： 如果您在以下任...
Vmware P2V conversion failed with showing grub prompt We tried to convert one of our physical machine running fedora15, using vmware tools. It started and failed exactly at 99% showing the following error“An error occured during the conversion GrubInstaller:InstallGrub: /usr/lib/vmware-converter/installGrub.sh failed with return code:1, and message: FATAL: kernel too old Error running vmware-updateGrub.sh through chroot into /mnt/p2v-src-root”Solution1. Boot the virtual machine with the fedora15 DVD and select the ‘rescue’ option.2. Once it boots chroot the /mnt/sysimage.3. While giving fdsik -l, im getting the following error“cannot open /proc/partitions”Also, mount too get some errors like unable to read etc., So exited the /mnt/sysimage by “exit” command4. Now, I gave the followingmount -o bind /proc /mnt/sysimagemount -o bind /dev /mnt/sysimageIf we didn’t mount the second one /dev, we will get blank when we give fdisk -l. Only “/dev/null” is present, nothin...
