Installing Git On CentOS

# Add the repository
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm

# Install the latest version of git
yum install --enablerepo=webtatic git-all

But there’s more!

Git SSL Certificate Problem On CentOS

If you’re following the installation instructions on GitHub or Bitbucket, you’ll notice that you’re now running into another error. Something like this: error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing.

We now need to download some SSL certificates. Some guides online recommend that you disable SSL authentication, but that’s a very dangerous road to travel. Instead, lets get the SSL certificates.

$  cd /etc/pki/tls/certs
$  curl http://curl.haxx.se/ca/cacert.pem | awk 'split_after==1{n++;split_after=0}
 /-----END CERTIFICATE-----/ {split_after=1} {print > "cert" n ".pem"}'
$  c_rehash

This should work for you up until the c_rehash command. Chances are, your system cannot find the command. Let’s fix that:

$  yum install openssl
$  yum install openssl-perl

Now, try the command and it should work:

$  c_rehash

Everything should be good to go! Continue following the directions provided to you on GitHub or Bitbucket, hopefully without any problems from here.

To remedy this, try running composer without scripts.

composer update --no-scripts

grep

“Better Start Greppin'”

I first heard of grep on Stack Overflow after searching Google for something along the lines of “how to search through my website for a line of code”. In one answer I read, “better start greppin’.” For a moment, I thought it said “reppin” — which I thought was an odd response — but a quick search revealed the real answer.

The grep command line utility was created in the 70’s for the exact purpose we want to use it for: to search through our website (to find where we put that buggy code?).

Here is the syntax for grep:

grep "some needle" inthehaystack.php

Searching Your Entire Site With GREP

The Scenario: You update WordPress, which seemingly works without issue, but then you notice that jQuery stopped working because of an error. In this case, the error would be a conflict issue between two jQuerys being loaded at the same time (one by your theme, one by WordPress). Now, you need to find the file that contains the one loaded by WordPress to prevent it from loading and throwing the error.

Navigate into your HTTP root directory with the “cd” command, then execute the following code:

grep -l -r "jquery" *

This will tell grep to return the filename (“-l”), recurse into sub-directories when looking (“-r”), and search through everything (“*”).

If you require even more functionality, you can find tens of thousands of detailed articles online about using grep in cases other than the ones I mentioned here. Good luck!

Before You Start: Download PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) to SSH into your server. I also recommend using Multi-tabbed PuTTY (http://ttyplus.com/multi-tabbed-putty/) for easy management of multiple servers.

The Source Server

SSH into the server that you want to take the files from, then navigate to the root HTTP directory using the cd command. Every server’s home paths are different so type ls to list the navigable directories available.

Once you’re in your HTTP root (often named “httpdocs”), use the following code to pack everything on your website into a single zip file:

zip -r example.zip *

While it packs, SSH into your other server (this is why multitabbed PuTTY is useful).

The Destination Server

Navigate to the HTTP folder on the new server (equivalent of “httpdocs”) using the cd command again, and once there, execute a cURL to download the zip file you created on your old server onto your new one.

curl -o example.zip http://theolderdomain.com/example.zip

Once it finishes downloading (watch the download counter), all you have to do is unpack the zip file and the files are fully transferred.

unzip example.zip

Keep in mind that this doesn’t move the server’s databases, only the file system. If moving large database structures, use phpMyAdmin’s built in export and import features.

Good luck!
