Need help with a script. MySQL and Sed
In an effort to ease some of my web development steps I plan on creating a script to automate everything. I run a drupal site and I need to set up a development environment quickly after I shut down the site for maintenance.
These are the steps that I need verified:
Steps to prepare the development environment
1. Drop all tables in my development Database (MySQL)
2. Remove all drupal files from development directory
Copying development site over to development
3. Copy main DB into dev DB
4. Copy drupal files to dev directory
Setting up the environment for testing
5. use sed (or a find and replace prog) to change $db_url = 'mysql://username: password@localhost/livedatabase'; to $db_url = 'mysql://username: password@localhost/devdatabase'; in drupal settings.php
6. Since the development site is accessible from the internet, I need to add some security to the new dev .htaccess file. I figured I could just add:
to a .txt file and use cat to dump it at the end of .htaccess.
So this is what I have so far, any help would be greatly appreciated.
Also I have Dreamhost so localhost will not work with connecting to MySQL databases I have to use something like 'mysql.sitename.com'
mysqldump -u[USERNAME] -p[PASSWORD] -h [HOSTNAME] --add-drop-table --no-data [DATABASE] | grep ^DROP | mysql -u[USERNAME] -p[PASSWORD] [DATABASE]
cd ~/devsite // safety measure for next line
rm -Rf ./*
$ mysqldump -u[USER] -p[PASSWORD] -h [HOSTNAME][DATABASE] | ssh firstname.lastname@example.org mysql [DATABASE]
cp ~/livesite/* ~/devsite/
I have no idea how to use sed need advice
cat ~/devsite/.htaccess << ~/htaccess-password.txt
Any advice would be greatly appreciated. Thanks!
For appending to ~/devsite/.htaccess, you could use
cat htaccess-password.txt >> ~/devsite/.htaccess
sed -i '/db_url = /s/livedatabase/devdatabase/' $file
You could have a list of files as well in the argument. This list might come from a find connand, and you could use xargs to add the files matching the search criteria to the end of the sed argument. The "-i" option to sed will cause each file to be edited in place instead of catenated together. Otherwise you would need to process each file in a loop and use a temporary file for the results, to prevent clobbering the original file. ( note: the -i option may not be available in some non-gnu versions of sed. )
Now that I think of it, I could just just copy the live sites settings.php file into another folder, mark it up the way I want and copy it into the development site via script. I would just have to check it on software upgrades. Much easier than using sed.
Thanks for all the help
Ok well that didnt work as planned. The only issue is emptying the devsite database; I get 'mysqldump:error 2002 (HY000)' and 'mysqldump:got errno 32 on write'. Everything else works to my knowledge except emptying the devsite database
Here is the command that isnt working:
mysqldump -u [USERNAME] -p[PASSWORD] -h [HOSTNAME] --add-drop-table --no-data [DATABASE] | grep ^DROP | mysql -u[USERNAME] -p[PASSWORD] [DATABASE]
Does anyone have a solution to get mysqldump to enter the DB and delete everything in it, while retaining the database?
Are you trying to use the output of grep ^DROP to the third command? If so use xargs.
However, I don't know if mysql will take multiple lines of input after the command.
Would 'DROP db_name.*;' work if you logged in without specifying a database?
If not, you could use:
mysqldump -u [USERNAME] -p[PASSWORD] -h [HOSTNAME] --add-drop-table --no-data [DATABASE] | grep ^DROP >temp
mysql -u[USERNAME] -p[PASSWORD] [DATABASE] <temp
