CentOS 7 安裝Python 3.6

工作用到,筆記一下

1.下載python 3.6
2.編譯安裝python3.6
3.修改預設python3.6

1.下載python 3.6

#mkdir /usr/local/python3
#cd /usr/local/python3
#curl -O https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz

2.編譯安裝python3.6

#yum -y install gcc*
#yum -y install zlib-devel
#yum -y install epel-release
#tar -xzf Python-3.6.0.tgz 
#cd Python-3.6.0

如果要把SSL模組帶入需要調整

#vi  Modules/Setup
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
#./configure --prefix=/usr/local/python3
#make;make install

3.修改預設python3.6

#mv /usr/bin/python /usr/bin/python.bak
#ln -s /usr/local/python3/bin/python3 /usr/bin/python

確認版本

#python -V

預設使用了python 3.6 則yum會無法正常運作,因為目前yum相依仍為python2.7,把yum設定改為python2.7 既可

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

測試安裝lrzsz

#yum -y install lrzsz
