Hi,
At some point in time, we may find it necessary to have a 2nd installation of Python (maybe another version) on our server. We'll need to do so without it affecting the current installation, lest it causes other dependent applications to break (chiefly, yum). So here's a little script in bash which automates the installation of Python 2.7 on a server at a different location.
This was tested on CentOS-5.9 (with the default Python version being 2.4.3)
#!/bin/bash
install_py(){
#These packages are used for the build process.
#More packages can be specified solely based on what modules you want this version of Python to use.
echo -e "\nSetting up the Install Environment. This will take some time..."
yum install zlib* zlib-devel readline-devel openssl-devel bzip2-devel wget gcc python-dev -y
# Compile and Build Python 2.7 under /opt
cd /usr/local/src/
wget http://www.python.org/ftp/python/2.7.1/Python-2.7.1.tgz
tar xvfz Python-2.7.1.tgz
cd Python-2.7.1
./configure --prefix=/opt/python2.7.1 --with-threads --enable-shared
make
make install
# for shared libraries
touch /etc/ld.so.conf.d/opt-python2.7.1.conf
echo "/opt/python2.7.1/lib/" >> /etc/ld.so.conf.d/opt-python2.7.1.conf
ldconfig
#Soft links for easy access
ln -sf /opt/python2.7.1/bin/python /usr/bin/python2.7
}
install_py
Run "python2.7" from the command line to verify the installation.
Until next time....
