linux/centos6.5下编译安装python2.7和python3.5.2

centos6.5环境下安装python2.7

解压python源码包
tar -xf Python-2.7.6.tar.xz

进入软件包目录
cd Python-2.7.6

添加配置项
./configure --prefix=/usr/local/python27

编译
make

报错

Python build finished, but the necessary bits to build these modules were not found:
_bsddb             _sqlite3           _ssl            
_tkinter           bsddb185           bz2             
dbm                dl                 gdbm            
imageop            sunaudiodev                        
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

centos安装盘中有相关的依赖包安装便可（readline）
方法：
将centos6.5的光盘挂载在/mnt/cdrom目录下
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom/Packages/

提示缺乏readline-devel包，安装readline-devel包的时候提示依赖ncurses-devel
 rpm -ivh ncurses-devel-5.7-3.20090208.el6.x86_64.rpm

 rpm -ivh readline-devel-6.0-4.el6.x86_64.rpm

删除相关的目录从新配置并编译
rm -rf /usr/local/python27
./configure --prefix=/usr/local/python27
make
make install
后面继续报缺乏依赖包直接忽略
②安装ipython1.2.1
tar -xf ipython-1.2.1.tar.gz

cd ipython-1.2.1

使用python27对ipython进行编译
/usr/local/python27/bin/python2.7 setup.py build
编译成功执行安装
/usr/local/python27/bin/python2.7 setup.py install


若是安装成功则在/usr/local/python27/bin目录下有一个ipython文件
ls /usr/local/python27/bin/


######################
将python和ipython连接到bin目录下，方便调用(直接输入python和ipython命令便可)
ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27

ln -sv /usr/local/python27/bin/ipython /usr/bin/

centos6.5环境python3.5的安装

安装相关依赖： yum -y install xz wget gcc make gdbm-devel openssl-devel sqlite-devel zlib-devel bzip2-devel 安装python3： wget http://mirrors.sohu.com/python/3.5.2/Python-3.5.2.tar.xz tar -xf Python-3.5.2.tar.xz cd Python-3.5.2 ./configure --enable-shared --enable-loadable-sqlite-extensions --with-zlib make && make install 添加python3命令： ln -sv /usr/local/bin/python3.5 /usr/bin/python3 vim /etc/ld.so.conf /usr/local/lib # 新增库文件路径 include ld.so.conf.d/*.conf # 使配置库生效 /sbin/ldconfig 版本检测 # python3 -V Python 3.5.2 之后直接运行python3就能够经过python3.5.2版本执行命令了
