Today Apache complained about SSLCertificateChainFile being deprecated and it told me to use SSLCertificateFile instead.
SSLCertificateFile was already in use with the .crt file. I had to create a new ‘SSLCertificateFile’ by concatenating the .crt file with the ca-bundle, and that fixed the problem:
# cat trust.jj5.net.crt trust.jj5.net.ca-bundle.pem > trust.jj5.net.pem
I followed these instructions to install PHP 5.4 on Ubuntu 12.04 LTS.
Basically:
$ sudo apt-get install python-software-properties $ sudo add-apt-repository ppa:ondrej/php5 $ sudo apt-get update $ sudo apt-get dist-upgrade
I had a problem with my rewrite rules, that looked like this:
DocumentRoot /var/www/trust.jj5.net
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) http://trust.jj5.net/sorry.html [L,R]
I was trying to redirect any request which didn’t match a file or directory. The !-f and !-d requirements were failing because the path to the REQUEST_FILENAME wasn’t fully qualified. I fixed the problem by including the DOCUMENT_ROOT:
DocumentRoot /var/www/trust.jj5.net
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
RewriteRule (.*) http://trust.jj5.net/sorry.html [L,R]
Happy days! :)
Learned about dir2ogg over here and am using it to convert MP3 to OGG.
So… I installed dir2ogg:
# apt-get install dir2ogg
And then I ran it on some MP3s, and the generated OGG files sounded like chipmunks. I read the man page for dir2ogg and saw that it had an option for mp3-decoder. I tried specifying the lame decoder but it complained that it couldn’t find it, so:
# apt-get install lame
Then I ran dir2ogg with the following command and the ouput OGG files sounded proper!
$ dir2ogg --mp3-decoder=lame --quality=10 .
Happy days!
To create a database and user account for use on PostgreSQL:
root@devotion:~# su - postgres
postgres@devotion:~$ psql
psql (8.4.21)
Type "help" for help.
postgres=# create user "www-data" superuser;
CREATE ROLE
postgres=# create database mydb with owner "www-data";
CREATE DATABASE
postgres=# \c mydb
psql (8.4.21)
You are now connected to database "mydb".
^
mydb=# alter user "www-data" with password 'secret';
ALTER ROLE
Postgres is only an apt-get away!
# apt-get install postgresql postgresql-client
To integrate with PHP PDO:
# apt-get install php5-pgsql
Today I installed the Open in Browser Firefox extension which lets me open files in Firefox rather than having to download them… handy!
On my development machine I want Apache to run under my user id so I can automatically generate files (and have permission to write them).
I configured Apache like this:
root@mercy:/etc/apache2# grep -R www-data . ./envvars:export APACHE_RUN_USER=www-data ./envvars:export APACHE_RUN_GROUP=www-data root@mercy:/etc/apache2# vim envvars export APACHE_RUN_USER=jj5 export APACHE_RUN_GROUP=jj5 root@mercy:/etc/apache2# apache2ctl graceful /var/lock/apache2 already exists but is not a directory owned by jj5. Please fix manually. Aborting. root@mercy:/etc/apache2# chown jj5:jj5 /var/lock/apache2 root@mercy:/etc/apache2# apache2ctl graceful
Easy-peasy!
Wait… that didn’t work. The problem was apache2ctl graceful didn’t pick up the new envvars file, this fixed it:
root@mercy:/etc/apache2# /etc/init.d/apache2 restart
Reading about how to create a RAM disk on Linux:
# mount -o size=200M -t tmpfs none /mnt/tmpfs
Getting spammed courtesy my Debian VMWare image, notifying me of an “mpt raid status change”. Looked here and fixed the problem with:
# /etc/init.d/mpt-statusd stop # update-rc.d -f mpt-statusd remove
