[Solved] ElasticSearch Error: FORBIDDEN/12/index read-only/allow delete (api) ,read_only_allow_delete Set windows

Elasticsearch reports an error. For bind/12/index read only/allow delete (API)
this error is because the indexes in elasticsearch are read-only and cannot be added or modified. Query the official website. The reason for this problem may be that the storage disk where es is located does not have enough space, which causes es to automatically turn on data protection and limit it to read-only

Solving fastdfs in Windows Environment_ Client installation error, error: Microsoft Visual C + + 14.0 is required

Problem recurrence:

building ‘fdfs_ client.sendfile’ extension
error: Microsoft Visual C++ 14.0 is required. Get it with “Microsoft Visual C++ Build Tools”: http://landinghub.visualstudio.com/visual-cpp-build-tools

Cause analysis:

You cannot PIP install FDFS directly under windows_ client_ py-1.2.6-py3.8.egg


1. First set FDFS_ client_ Py-1.2.6-py3.8.egg decompression

2. Then find FDFS_ Setup.py in the client py master directory

Comment out lines 34 and 35, as shown in the figure below:

3. Find FDFS again_ Storage under client directory_ client.py

Line 12 of note is shown in the figure:

4. Finally, find the directory where setup.py is located and execute

python setup.py install

You can find the installed FDFS in the interpreter in pycharm’s settings_ client_ py

5. Install the dependent packages mutagen and requests

pip install   mutagen

pip install   requests

Troubleshooting of nginx error under Windows: createfile() “XXX / logs / nginx. PID” failed



Under windows, when we execute nginx -s stop or Nginx -s quit  or Nginx -s reload   You may receive the following error messages:

nginx: [error] CreateFile() "D:/software/nginx/logs/nginx.pid" failed (2: The system cannot find the file specified)


When we use start Nginx   To start Nginx xxx/logs/   Generated under the directory named   Nginx.PID   The content of the file has only one number, that is, the PID corresponding to the nginx.exe process. Whether stop, quit or reload, you need to use the PID of nginx.exe to operate it. However, in some special cases (we will create a special case artificially below), Nginx.PID will be lost, so the above three commands will report an error because Nginx.PID cannot be found. Obviously, it is impossible to stop, quit or reload successfully at this time, because nginx doesn’t even know which process it corresponds to.


Simple and rough: 1) pass tasklist | findstr “nginx.exe”   Find out the PID corresponding to nginx.exe; 2) In xxx/logs/   New text file under Nginx.pid  , Write the PID of the previous step through the text editor (of course, this step can also be carried out through command line, script, hands-on programming and other methods that can achieve the purpose); 3) Execute Nginx -s stop or Nginx -s quit   Or Nginx -s reload.



In this verification, the nginx installation path is   D:/software/nginx  , The listening port is 5000.

The rendering method is a command-line screenshot. The commands used will be given in the form of text in the back, which is convenient for readers to copy and paste.

This paper only focuses on the problem of “unable to find nginx. PID”. For other problems derived from the verification process, this paper only gives the link of the answer and does not guarantee the right remedy (it does not mean that the document content is wrong, but does not guarantee that the corresponding problem can be solved). I also urge readers who know the answer to give me advice.

The commands in the verification process must be executed under the nginx installation directory, otherwise an error will occur. If you have to execute in any directory, please refer to another blog under. At the same time, remember to make corresponding changes to the relevant path.

The verification process is shown in the figure below:

Verification process

The commands used are sorted as follows:

1 start nginx
2 tasklist | findstr "nginx.exe"
3 netstat -ano | findstr "5000"   
4 type ./logs/nginx.pid
5 nginx -s quit
6 cmd /r dir /b .\\logs
7 13632 | Out-File -Encoding ASCII ./logs/nginx.pid


How to Share Files Between Linux and windows

1. Create users, directories and installation packages
yum install samba smbfs
useradd -s /sbin/nologin yunwei
smbpasswd -a yunwei
mkdir -p /date/yunwei
chmod 777 /data/yunwei
2. Configuration file
cp /etc/samba/smb.conf /etc/samba/smb.confbak
vi /etc/samba/smb.conf
comment = Home Directories
valid users = %S
browseable = No
writable = yes
create mode = 0664
directory mode = 0775

comment = yunwei
path = /data/yunwei
public = no
valid users = @yunwei
write list = yunwei
printable = no

3. Start the service
Red Hat Enterprise Linux Server release 6.4 (Santiago)
/etc/init.d/smb start
service smb reload
linux 7
systemctl start smb
systemctl status smb
4. Test the use of

Solutions to problems such as failed to load the hostfxr.dll of. Net core SDK after Windows system installation

The reason is that the problem of “failed to load the hostfxr. DLL” broke out after installing the. Net core SDK on a windows2008r2 computer and then executing dotnet -- info on the command line. It has also been encountered before, but it has been solved, but no record has been made, which has caused another Google here! So write an article and record it. In addition, some 500.25 problems are also caused by this reason!

Author: Yi lezhu

Original address: https://www.cnblogs.com/yilezhu/p/10057789.html

The specific error information is as follows:

Failed to load the dll from [C:\Program

Files \ dotnet \ host \ FXR \ version number \ hostfxr. DLL], HResult: 0x80070057

The library hostfxr.dll was found, but loading it from C:\Program

Files \ dotnet \ host \ FXR \ version number \ hostfxr.dll failed

Installing .NET Core prerequisites might help resolve this problem.

http://go.microsoft.com/fwlink/?LinkID=798306&amp ; clcid=0x409

The solution is to install this patch kb2533623. It should be noted here that different system versions need to correspond to specific patches, which can be divided into 32-bit and 64 bit. You can visit this page for specific information, https://support.microsoft.com/en-us/help/2533623/microsoft-security-advisory-insecure-library-loading-could-allow-remot

This article provides the corresponding updates of Windows 7 and Windows Server 2008 R2. Please download and install them. Then execute the dotnet -- info command to see the long lost interface:

It seems that this problem only occurs in Windows 7 and Windows Server 2008 R2.

Of course, there are other situations that cause the. Net core SDK to run abnormally! Sometimes you need to install the update kb2999226. Please fill it up next time! Because I didn’t record the last time I needed to install the update kb2999226!

the CMD environment of windows defaults to GBK encoding, and pip defaults to UTF-8 encoding
however, in Linux and MAC, the terminal environment defaults to UTF-8 encoding, so no error will be reported


Create a file sitecustomize.py in Python directory Python 27\lib\site-packages

import sys sys.setdefaultencoding('gbk')

Python will run this file automatically
