linux编译安装Python-3.6.7

linux版本：centos7

python版本：3.6.7

安装开发工具

[root@localhost ~]# yum -y install  zlib-devel bzip2-devel openssl-devel  sqlite-devel readline-devel gcc make pcre pcre-devel

如果在没有安装开发工具包，在编译的时候就会报一些错。

看见过很多小伙伴在编译的时候报错了，然后上网各种搜，其实就是开发工具没有安装，在这安装了之后编译的时候就不会报错了，当然也可以安装报错的时候再安装也行！

下载源码包

[root@localhost ~] wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7rc2.tgz

编译前的准备

vi Python-3.6.5/Modules/Setup.dist
修改

readline readline.c -lreadline -ltermcap

SSL=/usr/local/ssl
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

编译安装

[root@localhost Python-3.6.7rc2] ./configure --enable-shared

[root@localhost Python-3.6.7rc2] make && make install

vi /etc/profile.d/python3.6.7lib.sh
添加这么一行

#python-3.6.7共享库目录
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

vi /etc/ld.so.conf.d/python3.conf
添加如下内容

/usr/local/lib

保存退出
[root@localhost ~]# ldconfig
[root@localhost ~]# source /etc/profile
检查是否安装成功、出现如下内容表示安装成功

[root@localhost ~]# python3
Python 3.6.7 (default, Dec 24 2018, 11:03:47) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

exit()退出

[root@localhost ~]# python3

最后附上安装脚本

#!/bin/bash
#lyoyo
#install python3.6.7
yum -y install  zlib-devel bzip2-devel openssl-devel  sqlite-devel readline-devel gcc make pcre pcre-devel
wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7rc2.tgz
