Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

  https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

  VAGRANT_DISABLE_VBOXSYMLINKCREATE=1

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Buffer I/O Error in /var/log/messages

Host error message.

Buffer I/O errors occurring on SAN devices presented to Linux host using Linux native multipathing.
kernel: Buffer I/O error on device sdb, logical block 0
kernel: Buffer I/O error on device sdb, logical block 1
kernel: Buffer I/O error on device sdb, logical block 2
kernel: Buffer I/O error on device sdb, logical block 3

A server using a LUN, which is presented by a storage array through fabric channels, may show buffer I/O errors while the server is booting or commands such as fdisk and vgscan are being run. The access can be a read or write attempt. These messages are sometimes harmless. When using PowerPath, these errors are suppressed. However, in the case where Linux native multipathing is used, there is no automatic provision for filtering these messages.
The errors can occur when using an active/passive storage array, such as EMC Clarion series. These types of SANs contain two storage processors. LUNs are assigned to only one of the processors at the time of LUN creation. The LUN can receive I/O only via that one processor. The other processor is passive; it acts as a backup, ready to receive I/O if the active controller fails, or if all paths to the LUN via the active controller fails.
Paths to the LUN going via the passive controller are passive paths and will generate an I/O errors should I/O be sent over them. At bootup, the kernel’s SCSI mid-layer scans all paths to find devices. Thus it will scan both active and passive paths and will generate buffer I/O errors for the passive paths.
This is a normal behavior for Linux native multipath, and the errors do not indicate an array issue. The errors can safely be filtered through the OS logging configuration or the user can avoid access to native devices (as opposed to using /dev/mapper devices). Alternatively, a qualified version of PowerPath may be installed, which will automatically filter these errors.

[305]MYSQL 1062 error: duplicate entry ‘…’ for key ‘primary

Explanation:
Duplicate entry ‘… ‘For key ‘PRIMARY, the PRIMARY key data to be inserted into the data. It already exists. You can’t add it again. Example: Duplicate entry ‘0’ for key ‘PRIMARY refers to the data with a PRIMARY key value of 0 already exists, so the data with a PRIMARY key value of 0 can no longer be inserted.
Problem Solving:
Before the insert operation, you can perform the search operation SELECT for the primary key value, such as:
Perform an insert (0, “triple”) operation

insert into table(id,name) values(0,'Mr Three');

Duplicate entry ‘0’ for key ‘PRIMARY
can be added a judgment before insertion. If the PRIMARY key value is 0, it can be found, and it exists. If it cannot be found, the insert operation is performed.

select id from table where id = 0;

JSP exception message invalid TLD file

Today is going to start a core business system for a long time, after downloading the launch access JSP has been reporting this error

Java error: Message Invalid TLD File: see JSP 2.2 Specification section 7.3.1 for more details

After struggling for an hour, I found it after reading the error message in the document.

The JSP tag class file. TLD file cannot be placed under the Web-info classes,lib,tags file, while the old project’S TLD tag is just placed under the tags directory, so it will go straight to GG. The current solution is to move the TLD tag to another legitimate folder, and you can read the above mentioned documents if you are interested.

Linux FTP tip –553 Could not create file (absolutely useful)

Prompt 553 Could not create file, set the owner and permission of this directory, or report this error, then check carefully on the Internet, the problem is solved as follows:

This command can be printed out using the echo command.

Problem: ftp> Put the/home/hosts and ftp> Put hosts (the current directory is /home

) The parameters to be executed should be the same. Why can’t the former be uploaded?

 

When we come across this kind of problem, we should first analyze the reason

 

Consider whether selinux is a reason to try disabling SELinux

2. Maybe FTP folder does not have write permission, confirm the directory permission

3. Is there write_enable=YES in the configuration file

 

Solutions to error 25090 in office 2003

When you try to install, repair or uninstall Office, you may receive the following
Error message: Error 25090 Office Setup a Problem with the Office Source Engine, System Error: -2147023836 (Error 25090). Office installer has encountered problems related to Office Source Engine, system error: -2147023836)
Reason 1
The Office Source Engine (ose.exe) cannot be started because it has been stopped or disabled.
solution 1
Log in with administrative privileges.
right click “my computer”.
select manage.
click services and applications.
select service.
go to “Office Source Engine” and select enable the service.
Solution 2
 

modify the registry:
click start, click run, type regedit, find HKEY_LOCAL_MACHINE(abbreviated as HKLM), open the plus sign, then open SOFTWARE-> Microsoft-> Office-> 11.0 – & gt; Devilery, see the value of CDCache, change it to 0, OK! There is something wrong with WORD in my computer these days. Say what is missing iJ561401.CAB file. Each time it opens, a box appears.
I searched the Internet, finally found a set of WORD CAB files in one of the good website!
http://test.zlol.com.cn/%E5%BA%94%E7%94%A8%E8%BD%AF%E4%BB%B6/Office2003/OFFICE11/

in general

specific installation method:
1. Make sure you know which file you are missing before downloading. 2. Create a new folder and remember the location of the folder. 3. Find and download the files you need from this website, and put them into the new folder

4. When prompted to install office2003, enter the path to the saved file. Sometimes, for example, after you type in the path of “IJ561401.CAB “, a similar one pops up, telling you that another CAB file is missing, such as “ZA561401”, “YI541401”, “ZU61403”,

, you can do the same thing. You can put another folder in the same folder (at least that’s what I do, haha)

and if that works, WORD will open automatically at the end.

in the experiment, you open WORD again, directly appeared!! In addition, these CAB files on the Internet are all compressed files, I do not know whether I should decompress or not, at least I am decompressed in the same folder, no problem.

in WORD finally no longer out of the wind at the same time I would like to thank these find documents selfless dedication to the vast number of Internet users great people! There is a saying that “the power of Internet users is infinite”. It is precisely because of these selfless people who share their knowledge, power and resources. People can solve their own problems. Thanks again!

take the trouble to uninstall office, and then install again, it must be solved

Go start error: Panic: runtime error: invalid memory address or nil pointer reference

a pit about Golang variable scope


fix:
remove the colon from DB, err := gorm.open:

the original understanding was that golang would define the new variable err, DB was the global variable originally defined. But the reality is that for a variable defined with :=, if the new variable DB is not in scope with the same name as the defined variable (in this case, the global variable DB), then Golang defines the new variable DB to cover up the global variable DB, which is the real cause of the problem.

Solution to 1030 got error 28 from storage engine in MySQL

Problem Performance:

Solutions:

Mysql 1030 error does not have enough space, so clean up the disk space and restore normal use.

Mysql database had “Got error 28 from Storage Engine” error, so the problem was solved in this way.
1.

XML/HTML code

    disk temporary space is not enough. Solution: empty the/TMP directory, or change the tmpdir parameter in my.cnf to point to the directory with enough space

2,

XML/HTML code

    mysql> ERROR 1030 (HY000): Got ERROR 28 from storage engine
    the reason for this problem: there is not enough temporary space to execute this SQL statement solution: simply point tmpdir to a directory with a large hard disk space

Of course, both statements are the same. So there’s almost certainly no space left. I looked at the other disks and sure enough.

depressed, the backup file was deleted first normal.
