git基本环境配置

yum源中已有的git版太低，所以选择源码编译，也比较简单，由于git上许多项目需要python环境不同，因此保留系统自带的python2.x版本，并编译python3.x

# wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz
# tar xvf Python-3.5.2.tgz -C /usr/local/src
# cd /usr/local/src/Python-3.5.2
# ./configure --prefix=/usr/local/python3
# make && make install
# ln -sv /usr/local/python3/bin/python3.5 /usr/local/bin/python3

python编译报错
urllib.error.URLError: <urlopen error unknown url type: https>

安装openssl，openssl-devel后取消如下关于SSL的注释，在重新编译

vim Python-path/Modules/Setup.dist
207 #SSL=/usr/local/sslSL)/include -I$(SSL)/include/openssl \
208 #_ssl _ssl.c \ib -lssl -lcrypto
209 #       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
210 #       -L$(SSL)/lib -lssl -lcryptoefault because it breaks builds
