! [rejected]master -> master error: failed to push some refs to’https://github.com/ The ultimate solution

Git error:

$ git push -u origin master

To [email protected]:***.git

 ! [rejected]        master -> master (non-fast-forward)

error: failed to push some refs to '[email protected]:***.git

hint: Updates were rejected because the tip of your current branch is behin

hint: its remote counterpart. Integrate the remote changes (e.g.

hint: 'git pull ...') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Git already has some code in the repository, so it doesn’t allow you to overwrite your code directly. There are two ways to solve this problem:
method 1: force the code to github warehouse (recommended, save time and effort)

git push -f origin master		//直接强推，即利用强覆盖方式用你本地的代码替代github仓库内的内容

method 2: fetch git’s stuff to your local, merge and push

git fetch
git merge			//这两条命令等价于git pull  
git config branch.master.remote origin  
git config branch.master.merge refs/heads/master

Then pull git back and git pushes your code. Reference: Here.

Oracle 11gR2 RAC ohasd failed to start solution

CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
ohasd failed to start: Inappropriate ioctl for device
Ohasd failed to start the at/u01/app/11.2.0/grid/CRS/install/rootcrs. Pl line 443. When I installed 11gR2 RAC for the first time, I encountered this classic problem of 11.0.2.1. After checking on the Internet, I realized that it was a bug and the solution was very simple.
Just before root.sh, execute the following command
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
If there is a
/bin/dd: opening`/var/tmp/.oracle/npohasd’: No such file or directory
While the file is still running, it is not Adding a daemon to Inittab until it is ready to run. The DD command is usually executed while Adding a daemon to Inittab.
Another solution is to change file permissions
chown root:oinstall /var/tmp/.oracle/npohasd
To perform root. Don’t forget to delete the configuration before sh:/u01/app/11.2.0/grid/CRS/install/roothas. Pl – deconfig – force – verbose

Completely solve Mechanism level: Failed to find any Kerberos tgt

Error description
Secure Client Cannot Connect ([Caused by GSSException: No valid credentials provided(Mechanism level: Failed to find any Kerberos tgt)])
symptoms
If it’s not due to the validity of the Klist Keytab, and you return the error, if it’s a resident service, like nohup, Tomcat, etc., there’s a pattern to the error, like 12 o ‘clock every day, or after a certain period of time.

MongoNetworkError: failed to connect to server [localhost:27017] on first connect [Error: connect EC

Mongodb is installed, but the MongoDB server is not started.
Step 1: Open CMD and enter the MongoDB bin directory

Step 2: Enter the instruction: MonGod — dbPATH database path
If successful, it will be shown as follows:

Step 3: Leave the window open and open another CMD
Enter the bin directory of MongoDB again and enter Mongo, which is shown as follows:

 
 
Finally, you can run mongo on the console. Such as:

Failed to load resource: the server responded with a status of 503 (Service Unavailable)

If the corresponding JS reference is correct, a refresh will work fine
When you visit a web page, load a blank, and view a development script, you find a bunch of errors
Failed to load resource: the server responded with a status of 503 (Service Unavailable)

When switching to sources, it is found that the corresponding JS file has not been loaded

python sqlite Error IntegrityError: UNIQUE constraint failed: table_area1.user_name

This error is caused by the fact that when you were building the table, you set the key to be UNIQUE. When a user with the same name appears, the user will report
user_name INT NOT NULL UNIQUE
It’s also possible that this is the key that you just want to make unique but you insert this key twice later
for example you insert something with id 1
and then you insert something with id 1 because you can only have one field with id 1 so you get an error here

SSIS package error report login failed for user’nt authority\anonymous logon’ solution

Question link: http://social.msdn.microsoft.com/Forums/sqlserver/en-US/35139786-12bd-424a-9a60-27b5de981cd6/login-failed-for-user-nt-authorityanonymous-logon
This problem is called a Kerberos problem
The current credential cannot be passed to another server due to executing SSIS Package or other reasons in the database when you are currently logged into a database using Windows authentication. Therefore, your identity becomes anonymous Logon

Solutions:
Log in remotely to the server where the database is located and then perform the relevant actions
Or upgrade anonymous users of remote servers
