centos 更新python

標籤：

1、CentOS安裝Python的依賴包

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2、下載Python3.4的源碼包並編譯

wget https://www.python.org/ftp/python/3.4.1/Python-3.4.1.tgz
tar xf Python-3.4.1.tgz
cd Python-3.4.1
./configure --prefix=/usr/local --enable-shared
make
make install

3、在運行Python之前需要配置庫：

echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
ldconfig

4、運行示範：

python3 --version
Python 3.4.1

5、刪除編譯Python時所需要的庫

yum groupremove "Development tools" --remove-leaves
yum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel --remove-leaves

6、建立軟串連，使系統預設的 python指向 python3.4

mv /usr/bin/python /usr/bin/python2.6.6

ln -s /usr/local/bin/python3.4 /usr/bin/python
