So I’m in the middle of setting up a new VM with nginx and here’s what I do to build it so I don’t forget. It might also help you

$> su
$> apt-get install build_essentials libpcre3-dev libssl-dev
$> cd /usr/local/src
$> wget http://nginx.org/download/nginx-1.1.14.tar.gz
$> tar -xzf nginx-1.1.14.tar.gz
$> cd nginx-1.1.14

$> ./configure --with-http_ssl_module \ 
  --user=nginx \
  --group=nginx \
  --conf-path=/etc/nginx/nginx.conf \
  --pid-path=/var/run/nginx.pid \
  --error-log-path=/var/log/nginx/errors.log \
  --http-log-path=/var/log/nginx/access.log \
  --sbin-path=/usr/local/sbin/nginx \

$> make && make install

Your init script goes in /etc/init.d/nginx

First generate some deployment keys with ssh-keygen. Here’s some more info on adding your deploy keys to your git repo

So I need to set up my ssh config file in ~/.ssh/config like so…

Host project-a
  HostName github.com
  User git
  IdentityFile ~/.ssh/deploy_key_a_rsa
  IdentitiesOnly yes

Host project-b
  HostName github.com
  User git
  IdentityFile ~/.ssh/deploy_key__b_rsa
  IdentitiesOnly yes

Let’s say your two project git urls look like this:

  git@github.com:anon/project-a.git
  git@github.com:anon/project-b.git

You can now clone with the correct keys using..

  $> git clone project-a:anon/project-a.git
  $> git clone project-b:anon/project-b.git

String#capitalize just capitalizes the first letter of a string so it’s not exactly what I want.


"laura ann".capitalize
=> "Laura ann"
"o'shea".capitalize
=> "O'shea"


At a glance I couldn’t see any other ruby method or ActiveSupport method that does what I want here so a solution can be reached using String#gsub.


"laura ann".gsub(/\b([\S])/){|m| m.upcase}
=> "Laura Ann"

"o'shea".gsub(/\b([\S])/){|m| m.upcase}
=> "O'Shea"


For example, if you’re usinge FB.ui({method:'stream.share'})
The dialog gets its size from FB.UIServer.Methods.stream.share.size
Which is equal to {height:380, width:575} if you take a look at it in a javascript console.

So these dimensions are there to be changed if you need to.

Note, I was using the ‘feed’ dialog which is not present in FB.UIServer.Methods so I defined it after my call to FB.init so it would be available when I opened by dialog…


FB.init({appId: '[my app id]', status: true, cookie: true, xfbml: true});
FB.UIServer.Methods["feed"] = {size:{width:500,height:240}};


If you’re having trouble with the mysql gem version 2.8.1 on OSX 10.6 try uninstalling it and building it this way:


sudo gem uninstall mysql



export ARCHFLAGS="-arch i386 -arch x86_64" ; gem install --no-rdoc --no-ri mysql -- --with-mysql-dir=/usr/local --with-mysql-config=/usr/local/mysql/bin/mysql_config


The gem should build with no errors or warnings. The paths to mysql-dir and mysql-config are standard paths used by the mysql dmg, you might want to check your own paths first with:

which mysql_config


I’ll also be attempting yet again to keep blogging. My blog will be very tech focussed and will more often than not highlight tech issues and solutions that I come up against in my work. It will be pretty random, more of a repository of gotchas for myself and anyone else who happens to be doing similar stuff.

I had a quick look with ifconfig eth0 to see what was going on. These were the lines of interest from the output:

RX packets:404933416 errors:0 dropped:0 overruns:0 frame:0
TX packets:501341708 errors:31383248 dropped:0 overruns:11 carrier:62766496

Obviously something is not right.
I spent a while reading through log files to no avail, this isn’t really my area of expertise so I gave in and contacted my hosting provider.

A Digiweb engineer got back to me very quickly advising me to check if the network interface was running at half-duplex.
I used ethtool to check this out:

john:~$ sudo ethtool eth0
Settings for eth0:
	Supported ports: [ TP MII ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	Advertised auto-negotiation: Yes
	Speed: 10Mb/s
	Duplex: Half
	Port: MII
	PHYAD: 32
	Transceiver: internal
	Auto-negotiation: on
	Supports Wake-on: pumbg
	Wake-on: d
	Current message level: 0x00000007 (7)
	Link detected: yes

The interface was only running at 10Mb/s half-duplex.
It seems auto-negotiation of the link had failed.

john:~$ sudo mii-tool eth0
eth0: autonegotiation failed, link ok

I fixed this be turning off auto-negotiation and applying the desired settings to eth0 with the following command:

john:~$ ethtool -s eth0 speed 100 duplex full autoneg off

Then to make sure this is always done with the interface is being brought up I added that command to /etc/network/interfaces just after the iface line:

iface eth0 inet static
pre-up /usr/sbin/ethtool -s eth0 speed 100 duplex full autoneg off

Having done this, the error count on eth0 hasn’t increased. Job done.

I solved the problem by doing the following.
First I found out where java actually was with:
>ls -l' `which java`
/usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

I noticed a command called java_home in that same directory. Running that command yields the correct java home directory.
>/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home

To correctly set the my JAVA_HOME environment variable in future, I added the following to my ~/.profile

export JAVA_HOME=`/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home`

Once you have done this you can restart your terminal window or run >. ~/.profile to reload you profile into the current terminal session.

sudo gem install passenger
cd `passenger-config --root`
rake nginx

Download latest stable nginx tarball. (currently 0.6.36) to the directory of your choice, then, in that directory

tar -xzf nginx-0.6.36.tar.gz
cd nginx-0.6.36
./configure --with-http_ssl_module --add-module=`passenger-config --root`/ext/nginx
make
sudo make install

OR

If you already have nginx installed you might just want to copy the nginx binary from objs/nginx and replace the existing nginx binary with that.

cp -f objs/nginx /usr/local/nginx/sbin/nginx

Edit the nginx.conf (should be in /usr/local/nginx/conf) to add passenger_root, again you can get this path with passenger-config --root.
Create a virtual host with a root in the rails app public dir and set passenger_enabled on; also set rails_env development;. It is important that the server root directive is set to the public directory of your rails app.

The following is an excerpt from my nginx.conf with passenger relevant config only:

http {
  #
  #
  passenger_root /Library/Ruby/Gems/1.8/gems/passenger-2.2.2;
  #
  #
  server {
    listen 80;
    server_name www.example.com;
    root /some/path/to/my_rails_app/public;
    passenger_enabled on;
    rails_env development;
  }
  #
  #
}
