How to export from git

To export a project from git, we need to use the 'archive' command of git. Archive command has several different options. we can export from remote host using the '--remote' option.

To change the format of the export file compression we can set it using '--format' option. And also we modify the level of compression from 0 to 9.
And we specify the output file path where we want to store the exported files.

The following command will export content into 'b' folder with zip compression.

git archive HEAD --format=zip > b.zip

is not allowed to connect to this MySQL server

I was connecting to a remote mysql server from my machine. And I was getting this error:

is not allowed to connect to this MySQL server

To accept remote connection to mysql server, we need to modify the my.cnf file on which the mysql server is running.
Go to /etc/mysql/my.cnf.
And comment out the following line:

bind_address = 127.0.0.1

Now run the below command on the remote mysql server machine:

$ mysql -u root -p
Enter password:

mysql> use mysql

mysql> GRANT ALL ON *.* to root@'192.168.1.4' IDENTIFIED BY 'your-root-password'; 

mysql> FLUSH PRIVILEGES;

we assume that 192.168.1.4 is the ip from which the request would be made to the remote mysql server.

File backup with rsync

rsync provides us to synchronize two folders. We can also make the synchronization over remote servers with ssh or rsh. There are different options we can use according to our need. The following command helps us to make an incremental backup of our filesystem:

rsync -a --delete source/ destination/

The delete command will remove the deleted files of source from the destination.

Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller class

The error message
Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller class
If you come across with this error. then there is some problem with your application configuration file and the module file name pattern.
Your module section of the configuration file should look like this:

resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.frontController.defaultModule = "auth"
resources.frontController.params.displayExceptions = 0
resources.modules = ""
 

And don't add prefix to the IndexController and ErrorController file name. Left it as it is.
Or if you use the below line in your configuration file

resources.frontController.params.prefixDefaultModule = "1"

Then you need to add prefix to the above classnames, not filename.
