.htaccess: Invalid command ‘ExpiresActive’ and .htaccess: Invalid command ‘Header’

Apache

 

.htaccess: Invalid command ‘ExpiresActive’, perhaps misspelled or defined by a module not included in the server configuration,
ln -s /etc/apache2/mods-available/expires.load /etc/apache2/mods-enabled/
.htaccess: Invalid command ‘Header’, perhaps misspelled or defined by a module not included in the server configuration
a2enmod headers

At the end… restart Apache!

service apache2 restart

Warning: Unknown: open(/var/lib/php/session/ O_RDWR) failed: Permission denied (13)

CentOS, nginx, PHP

I was getting the following error on a *fresh* CentOS…

Warning: Unknown: open(/var/lib/php/session/sess_isu2r2bqudeosqvpoo8a67oj02, O_RDWR) failed: Permission denied (13) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

This will do the work…

chown -R nginx:nobody /var/lib/php/session && chmod -R 770 /var/lib/php/session

mysql – search & replace HUGE databases

MySQL

So!, I have with almost 3Gb… and I need to make a search & replace…
This looks the best way to me…

EXPORT FROM MYSQL > LINUX SEARCH & REPLACE > IMPORT TO MYSQL

Dump database to text file

mysqldump -u user -p databasename > ./db.sql

Run sed command to find/replace target string

sed -i 's!oldString!newString!g' ./db.sql

Reload the database into MySQL

mysql -u user -p databasename < ./db.sql
