Getting “Symbolic link not allowed or link target not accessible” while configuring Apache?

Reconfiguring my dev environment, I decided to change the location of my local web server directories, from /var/www to ~/, so that I could just backup my Home folder, and I’d only need to set some symbolic links when restoring or reinstalling my OS.

The problem arised when I did in fact move all to ~/, configured symbolic links, and I was still getting “Symbolic link not allowed or link target not accessible” in my Apache 2 logs.

Long story short, I had to add execute permission to /home/lobo to www-data user. That allows the os to CD to /home/lobo/mysite. So:

chown :www-data /home/lobo

chmod g+x /home/lobo

That did the trick!

Edit:

The fact is that you need permission to CD to the whole path. Doing sudo su www-data and cd’ing /home then /home/lobo throwed the error, then added the necessary permissions to “lobo” and finally inner folders so that Apache could work with them (755 to all directories and below works).

byobu (screen) stopped working. Here’s how I solved it!

My byobu was working ok until a couple of days.

it closed the very second i started it, saying [screen is terminating].

I had to remove it since it didn’t allow me to use my terminals.

Steps to solve my situation:

1. add to “/etc/fstab” this line: “none /dev/pts devpts defaults 0 0”
2. reboot
3. open byobu (or screen)
4. a page that made me press return or space to continue appeared. Apparently, this was stoping byobu from working.
5. removed the line added in step 1
6. reboot
7. now we are working again, with byobu

This page helped me to know which command to use: http://forum.slicehost.com/index.php?p=/discussion/2577/screen-no-more-ptys/p1

The fact that a confirmation “screen” appeared after starting byobu, made me think of this halting byobu on the first time.

Running “good citizen” Yii Console Commands

When you run a website, that has commands running using cron, you should run your commands as the same user as your website (ex: apache, www-data).

Here’s a simple how-to:

1. give access to www-data to execute yiic
2. run yiic through /etc/crontab, not via “root“‘s crontab (the one you configure running crontab -e). This /etc/crontab has a new column for the username, so you can run commands via www-data

my /etc/crontab says:

*/1 * * * * www-data /bin/scripts/sendMail.sh> /dev/null

Of course, you have to give access to www-data  to run sendMail.sh

Adding CSS prefixer to the toolbox

Now I just want all browser specific prefixes to be added automatically on my compilelesscss shell script.

This can be done thanks to the work done by http://cssprefixer.appspot.com/

You can run it from the web (not very usable), or just run: sudo pip install —upgrade cssprefixer

Now you can run cssprefixer yourcssfile.css >newcssfilewithprefixes.css

Done!

How to solve “The following packages have been kept back: libmysqlclient16”

I have been getting this msg from my linux apt-get upgrade.

After researching, it was caused by having mysql-workbench-gpl, that apparently installs mysqlclient, and having percona-mysql installed.

Running

aptitude upgrade —full-resolver

offered me choices: remove mysql-workbench-gpl, or percona.

I removed mysql-workbench-gpl, thus, upgraded percona, and later reinstalled mysql-workbench-gpl.

Now we are all happy again :)
