Today I found out one of the CentOS 7-1611 VMs has no GUI available and also there is no SSH login at the console.

Worst the screen indicates “[sda] Assuming drive cache: write through”, seems it’s hang at startup.

In fact it’s working fine, then I SSH into the server remotely, and issue “systemctl set-default multi-user.target” which set the default login interface to be text based SSH login, the SSH login screen appears after the reboot.

systemctl isolate multi-user.target to return to command mode
systemctl isolate graphical.target  to return to graphical mode

Somehow, systemctl isolate graphical.target turns the screen into blank, still have no idea what’s causing this, nor startx works.

Finally, the vCenter VM Guest OS status changed from CentOS 4/5 64 bits to Other (32-bit) automatically everything after reboot, anyone knows why? Pls drop me a line, thx.

默認情況下，無論是IIS6對中文路徑或文件名支持的不是很好，主要表現為：圖片中含有中文路徑顯示無法找到网頁；含有中文的文件直接使用IE下載的時候出現無法找到的錯誤等等。

解決方法：

打開注冊表中的HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\InetInfo\Parameters\，
新增的FavorDBCS設置為0，然后重啟IIS。

Definitely a big surprise from M$ to release a hotfix for WannaCry for all their EOL products!

This is what my friends showed to me recently.

When Dell ran out of Equallogic disks (15K RPM, 600GB 3.5″ SAS), they supplied him with this alternative solution.

A 2.5″ 15K RPM, 600GB SAS!

This is how it fits into the original 3.5″ tray, seems the tray is a revised version with 4 new holes on the back in order to fit that 2.5″ SAS disk.

The trick is to create an extra environment variable PHPRC and point to the specific PHP version directory that contains php.ini.

* DO NOT put an extra \ at the end, ie, C:\Program Files (x86)\PHP 7.1.5 is the correct form without the ending \.

* Make sure you downloaded the Non-Thread Safe x86 version for PHP release

Extra Note:

For FastCGI on Windows Server 2003, the last supported binary Non-Thread Safe x86 version of PHP is 5.4.9. (ie, php-5.4.9-nts-Win32-VC9-x86.zip)

Enable the User-Defined INI files

If you want to allow Web application owners to control PHP settings themselves, you can enable a user-defined PHP configuration.

1. Add the following setting, which specifies the name to be used for user-specific INI files, to the main php.ini file. Setting this to an empty value disables the user-defined PHP configuration.

   consoleCopy

   user_ini.filename = .user.ini
   

2. Create a file called .user.ini in C:\inetpub\website1.com\ folder, and add the following:

   consoleCopy

   max_execution_time = 300
   

3. Add the following to the file .user.ini in C:\inetpub\website2.com\ folder:

   consoleCopy

   upload_max_filesize = 12M
   

   Note that if your main php.ini file has [PATH] sections that point to the root folders of these sites, then you need to remove those sections; if you do not remove those sections, the user-defined settings will not take effect.

4. Use phpinfo() or ini_get(”max_execution_time”) to check that the new settings have overwritten the default settings. Create a PHP file with the following text and save it in the Web root folder:

   XMLCopy

   <?php phpinfo(); ?>
   

5. Open the PHP script on the Web site http://localhost/phpinfo.php.

6. Note also that when you enable the user-defined INI files, the settings in those files are cached by the PHP engine to avoid re-reading those files for every request. This means that if the user makes a change to .user.ini file, then that change may not take effect right away. Instead it may take effect after the cache time to live (TTL) has expired. The cache TTL value is controlled by the php.ini setting user_ini.cache_ttl, which is set to 300 seconds (5 minutes) by default.

Fore detail, please refer to Enable Per-Site PHP Configuration on IIS 7.

The following settings can be used to tighten the security of a PHP installation. To make the recommended changes, locate and open the php.ini file and edit the configuration settings as described below:

Got a surprise today! It turns out this is the default policy for the new CentOS, all you need is to modify /etc/sysconfig/network-scripts/ifcfg-eth0 and change ONBOOT=no to ONBOOT=yes. In additional Static IP setups would need to set BOOTPROTO=static.

GrpName> mem sel <member name> disk select 0

GrpName(member_MEMBERNAME disk_0)> ?

clear-label          - Clears the label on the selected disk if the disk contai

Just make DOUBLE sure you have the correct drive number.  Remember first drive number is ZERO (0) not one (1).

You can issue it as one command.  mem sel membername disk select <number> clear-label

However, I prefer to select the drive first.  Then do a “show” to make sure it’s the disk I want.

show

After almost 6 years since the release of ESX 4.1 in Aug 2010, vSphere 6.5 has finally arrived. However imoo, I would still prefer to call it ESX 4.5 at max as there are not much new and useful  features added to be honest.

vCenter Server Appliance 6.5 (VCSA) is probably the most interesting one as it comes with native high availability, so no more worry about that single point of failure.

Other than that, I bet most of the 99% out there won’t really find those so called new feature useful in their daily operation.

In additional, seems there is no major change in VMware’s licensing model, remember that horrible vRAM tax back in 2012?

Finally, I am looking for Total SSD storage solution recently, and my eyes are on Pure Storage, but why their stock PSTG is dropping like hell?
