Ran into another issue because of my recent upgrade to Lion. I use Coda for dev work and have grown used to the built-in source control. One of the features in Coda is a compare files function which uses the FileMerge.app to display the differences.
Knowing that FileMerge is part of the developer tools I proceeded to download the Xcode application from the Mac App Store. To my dismay FileMerge still did not want to compare the files.
After some digging I found Coda uses the `opendiff` command to launch FileMerge. Running the command manually brings up the following error message:
xcode-select: Error: No Xcode folder is set. Run xcode-select -switch <xcode_folder_path> to set the path to the Xcode folder.
So it seems like `opendiff` doesn’t know where your Xcode.app is by default. To fix it, run the following command:
sudo xcode-select -switch /Applications/Xcode.app
The compare files feature in Coda now works as expected.
When setting up a new OS X install, one of the settings I always set in the Terminal.app is the `Use option as meta key` option. This allows you to use the Option key instead of Esc as the meta modifier.
One of my Terminal uses is running IRSSI inside a screen session. To switch between windows in irssi I always use `option + left/right arrow` however in Lion this does not seem to work by default.
After some googling I didn’t find anything that offered a solution so I dug through the Terminal.app preferences and noticed some additional presets in the Keyboard tab that aren’t there is previous versions of OS X.
To fix it, in Terminal.app go to
Preferences -> Settings -> Keyboard
Locate the two settings
`option cursor left` and `option cursor right`
as named in the Key column and delete them by selecting one and click the - (Minus) button at the bottom of the window.
Download the latest beta release from the Downloads page.
Install from the RPM (if updating use ‘rpm -Uvh’ instead):
rpm -ivh sphinx-2.0.2-1.el5.x86_64.rpm
Enable auto-lauching of the search daemon on boot:
chkconfig --level 345 searchd on
Start the search daemon:
Having mysql/php/apache already setup I decided to install phpMyAdmin, however because the mysql is Percona there were some dependency checks that failed.
After a lot of trial and error the following did the trick:
#stop the services /etc/init.d/httpd stop /etc/init.d/mysql stop #remove mysql yum --enablerepo=remi remove Percona* mysql* #install everything in one shot yum --enablerepo=remi install Percona-Server-server-55 Percona-Server-client-55 phpMyAdmin #start the services /etc/init.d/httpd start /etc/init.d/mysql start #rerun the secure installation script /usr/bin/mysql_secure_installation
Once that has finished you’ll need to edit the apache config to allow you remote access to the phpMyAdmin site:
nano /etc/httpd/conf.d/phpMyAdmin.conf #add allow from your ip address allow from 123.456.789.101
You should now be able to access it at http://example.com/phpMyAdmin/
To change the default scheduler from cfq to deadline simply edit /etc/grub.conf and add elevator=deadline to the kernel that is being used:
$ nano -w /etc/grub.conf title CentOS (2.6.18-274.3.1.el5) root (hd0,0) kernel /vmlinuz-2.6.18-274.3.1.el5 ro root=LABEL=/ elevator=deadline initrd /initrd-2.6.18-274.3.1.el5.img
This entry tells the 2.6.18-274.3.1.el5 kernel to use the Deadline scheduler. Make sure to reboot the system to activate the new scheduler.
