Database is the most important file other than web file, hence the backup is very important for the web developer and web owner.
By referring to the current post, you may backup your database automatically from your Linux box.
# Specify the temporary backup directory
# Database Name
# store the current date
# Specify Ftp details
# Dump the mysql database with the current date and compress it.
/usr/bin/mysqldump -u$dbuser -p$dbpasswd $dbname | gzip > $BKUPDIR/$date.$dbname.sql.gz
# Change directory to the backup directory
# Upload the backup
ftp -n $ftpserver <<!EOF!
user $ftpuser $ftppass
# Remove the local backup file
/bin/rm -f /$BKUPDIR/$date.$dbname.sql.gz
With the above script, you may save it as file.sh and just schedule a cronjob to run it as your needed time.
Assume that you are using crontab to schedule your task which you are using Unix system.
To schedule a database backup, it will be very easy as step below.
1. Log into your SSH.
2. Type “crontab -e” without quote.
3. Enter the command below.
0 0 * * * date=`date -I` ; mysqldump -a -u[user] -p[password] [dbname] | gzip > /path/folder/[dbname]_$date.sql.gz
where you shall replace the user, password and dbname to your database information.
With the command as above it will actually backup your database by 12.00AM daily and place to the desired path and name with date.
Many of the website did teach how to check HTTP Compression, what Apache module is needed, but there are less guide on how to make it done.
Today, Mick Genie will guide you how to make it done.
Firstly, you may need to compile your Apache with mod_gzip and mod_deflate (Actually Apache 1.x needed mod_gzip and Apache 2.x needed mod_deflate, hence you may compile both of them).
Once done, modify your httpd.conf and assume it is located in /usr/local/apache/conf. Add the following line to the configuration file.
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary
Restart the httpd services.
service httpd restart
The above command from httpd.conf will compress all the files except the .gif, .jpe, .jpeg and .png files.
