CentOS7上Python-3-6的安装

# 1、先解决依赖

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel wget gcc gcc-c++

# 2，下载源码并安装。

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
tar xf Python-3.6.3.tgz
cd Python-3.6.3
./configure --prefix=/usr/local && make && make altinstall

# 3，更改 / usr/bin/python 链接

cd /usr/bin && mv  python python.backup && ln -s /usr/local/bin/python3.6 /usr/bin/python &&ln -s /usr/local/bin/python3.6 /usr/bin/python3 && ln -s /usr/local/bin/pip3.6 /usr/bin/pip

# 4，更改两个依赖。

/usr/bin/yum
/usr/libexec/urlgrabber-ext-down

分别把两个文件的第一行尾部加上 2

#!/usr/bin/python 改为 #!/usr/bin/python2
 
sed -i '1s/python/python2/g' /usr/bin/yum
sed -i '1s/python/python2/g' /usr/libexec/urlgrabber-ext-down
