centos上安装drush

CentOS Linux

There are 2 ways to do this on centOS, one preferably being the pear install below

Pear CentOS Install #1 (similar to above except #2)
-------------------------------

1. Check if PEAR is on the server with: pear version

2. If PEAR is not on the server then type in: yum install php-pear

3. Then type in: pear channel-discover pear.drush.org

4. and then finally: pear install drush/drush

4a. if you would like to install a specific version, you can do this (for instance drush 6.x requires php 5.3.3, so you may want to use the 5.x branch instead):pear install drush/drush-5.7.0

If something goes awry, you can always uninstall drush with: pear uninstall drush/drush

安装ruby

I am using CentOS 6.3, below is easy steps to install ruby using RVM , or Ruby Version Manager. RVM provides easy set of commands to install single or multiple versions of Ruby on single server.

Step 1: Upgrade Packages

It is the best practice to keep your system up to date with latest packages. Before running below command make sure that update will not affect to your running apps ( if any )on server else skip it

# yum update

Step 2: Installing Recommended Packages

There are few developemnt libraries required to run Ruby on Linux. Use following command to install recommended packages on your server using yum.

# yum install gcc-c++ patch readline readline-devel zlib zlib-devel # yum install libyaml-devel libffi-devel openssl-devel make # yum install bzip2 autoconf automake libtool bison iconv-devel

Step 3: Install RVM ( Ruby Version Manager )

Install latest stable version of RVM on your system using following command. This command will automatically download all required files and install on your system.

# curl -L get.rvm.io | bash -s stable

Step 4: Setup RVM Environment

After installing RVM first we need to setup rvm environment using below command.

# source /etc/profile.d/rvm.sh

Step 5: Install Required Ruby Version

RVM provides option to manage multiple ruby version on single system. Use following command to install required version of Ruby.

# rvm install 1.9.3

Step 6: Install Another Version ( if Required )

If you want using multiple versions of ruby, you can install it also using rvm else skip this step.

# rvm install 1.8.6

Step 7: Setup Default Ruby Version

Use rvm command to setup default ruby version to be used by applications.

# rvm use 1.9.3 --default Using /usr/local/rvm/gems/ruby-1.9.3-p545

Step 8: Check Current Ruby Version

Using following command you can check the current ruby version is used.

# ruby --versionruby 1.9.3p545 (2014-02-24 revision 45159) [i686-linux]

I hope above steps will help you for installing multiple Ruby version using RVM.
