Under CentOS When upgrading to 2.7.6, there is no installation package installed directly, only the source code compiled to install Python version 2.7.6. This is a process record for compiling and installing Python2.7.6.

Development tools is installed in the CentOS system. To compile and install Python, execute the following code:

$ pushd/usr/local/src$ sudo mkdir python$ sudo chown $USER python$ cd python$ wget https://www.python.org/ftp/python/2.7.  6/python-2.7.  6.tgz$ tar zxvf python-2.7.  6.TGZ$ cd python-2.7.  6$.  /configure--prefix=/usr/local/python-2.7.  6 &&make$ sudo make install            

Code procedures:

1. /usr/local/src Create the Python folder and set the Python folder owner to the current user (not root)

2. Go to the created Python directory and download the python2.7.6 source code package from the official website.

3. (non-mandatory) if you want to verify the consistency of the package, you can download the sig file on the official website, and through the PGP check file, you can also verify the downloaded compressed package by the MD5 available on the website. For more information on verification, refer to the integrity of the check file under Linux (MD5,SHA1,PGP). This code ignores this procedure.

4. Unzip the package into the current directory and enter the Python-2.7.6 directory

5. Configure Python and compile. This step only uses --prefix parameters to indicate the installation path.

6. Install Python

The above is a rough process in the case of a successful Python compilation installation, but when I compile it, Python has the following message:

Found:   _bsddb             _sqlite3           _ssl   _tkinter           bsddb185           bz2   dbm                gdbm               readline   sunaudiodevmodule' s name. 

Of course, each machine because of different configuration, compile error message will be different, such as online someone's error is the following:

Found:  _bsddb _curses_curses_panel  _sqlite3  _ssl_tkinter   dl Gdbmimageop ReadLine Sunaudiodev zlibmodule' s name.     

Regardless of the error message, meaning is very clear, we compile, the system does not have the means to find the corresponding module information, in order to resolve these errors, we need to install the dependency package in advance, these dependencies are listed as follows (not necessarily complete):

Module	Depend on	Description
_bsddb	Bsddb	Interface to Berkeley DB Library. Interface to the Berkeley database
_curses	Ncurses	Terminal handling for Character-cell displays.
_curses_panel	Ncurses	A panel stack extension for curses.
_sqlite3	Sqlite	DB-API 2.0 interface for SQLite databases. Sqllite,centos can be installed Sqlite-devel
_ssl	openssl-devel.i686	Tls/ssl wrapper for socket objects.
_tkinter	N/A	A thin object-oriented layer on top of TCL/TK. If you do not use a desktop program, you can ignore Tkinter
bsddb185	Old BSDDB Module	Old BSDDB module, can be ignored.
bz2	bzip2-devel.i686	Compression compatible with bzip2. Bzip2-devel
Dbm	Bsddb	Simple "Database" interface.
Dl	N/A	Call C functions in shared objects. Python2.6 started, has been deprecated.
gdbm	gdbm-devel.i686	GNU ' s reinterpretation of dbm
Imageop	N/A	Manipulate RAW image data. has been deprecated.
ReadLine	Readline-devel	GNU ReadLine Interface
Sunaudiodev	N/A	Access to Sun audio hardware. This is for Sun platform, can be ignored under CentOS
Zlib	Zlib	Compression compatible with gzip

Under CentOS, these dependency packages can be installed: readline-devel,sqlite-devel,bzip2- devel.i686,openssl-devel.i686,gdbm-devel.i686,libdbi-devel.i686,ncurses-libs,zlib-devel.i686. After you have completed these installations, you can compile them again, and the module errors specified in the table above as deprecated or ignored can be ignored.

After the compilation is complete, you can then install Python to the specified directory in the sixth step above. After the installation is complete, we can see if Python is installed properly under the installation directory.

$ pushd/usr/local/python-2.7.  6/bin$ python--version$ sudo mv/usr/bin/python/usr/bin/python.old$ sudo ln-s python/usr/bin/python$ p OPD$ python-V"s/#\!\/usr\/bin\/python/#\!\/usr\/bin\/python.old/"/usr/bin/yum    

1. We go to the bin directory under the installation path and view the installed version (version 2.7.6)

2. Rename the existing Python version to backup

3. Create a new version of Python to /usr/bin replace the original python in the directory

4. Test the System Python version (should be the new 2.7.6)

5. If Yum does not work properly, you can simply replace the Python reference with the original Python path via sed.

At this point, complete the Python update compilation installation. If you want to complete the automatic installation, you can save the previous code as a shell script file-it is important to note that you may need to add the installation scripts for each module, which is installed through Yum. You can also refer to the article in 2, which contains the script files that are automatically installed.

1. Python official website

2. Install Python 2.7.2 on CentOS 5.2, including automated installation scripts.
