CentOS7 安装 Python3.7 及 SSL 编译错误处理

下载: https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

解包:tar -zxvf Python-3.7.0.tgz

进入 Python-3.7.0 目录:

    cd Python-3.7.0

 

1. 安装必要的依赖模块:

执行下面的安装指令:

[devalone@nutch Python-3.7.0]$ sudo yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite sqlite-devel readline-devel tk tk-devel gdbm gdbm-devel db4-devel libpcap-devel lzma xz xz-devel libuuid-devel libffi-devel

 

2. 尝试配置、编译

[devalone@nutch Python-3.7.0]$ ./configure --prefix=/usr
[devalone@nutch Python-3.7.0]$ make


编译错误:
Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381

 

3. 安装 libressl 代替openssl-devel
-------------------------------------------------------------------------------------------------------------------------

libressl 是 openssl 更安全版本分支,生产环境建议使用 libressl 替代 openssl。

 


下载最新稳定版本 2.7.4

https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-2.7.4.tar.gz

解压:
    tar -zxvf libressl-2.7.4.tar.gz

编译安装:
    [devalone@nutch libressl-2.7.4]$ cd libressl-2.7.4
    [devalone@nutch libressl-2.7.4]$ ./configure --prefix=/usr/local
    [devalone@nutch libressl-2.7.4]$ sudo make install

新建或修改 /etc/ld.so.conf.d/local.conf 配置文件,添加如下内容:
    /usr/local/lib
    
即将 /usr/local/lib 目录加入到模块加载目录。

重新加载共享模块:
    [devalone@nutch Python-3.7.0]$ sudo ldconfig -v

    [devalone@nutch Python-3.7.0]$ openssl version
    LibreSSL 2.7.4

 

4. 安装 libressl 代替openssl-devel
-------------------------------------------------------------------------------------------------------------------------
回到 Python-3.7.0 目录,编辑安装文件 Modules/Setup

删除有关 ssl 编译代码的注释,共 4 行,并修改 SSL 目录为 SSL=/usr/local, 如下所示:

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

重新配置、编译:

   [devalone@nutch Python-3.7.0]$ ./configure --prefix=/usr

    [devalone@nutch Python-3.7.0]$ make

编译成功,没有报错,执行安装:
    [devalone@nutch Python-3.7.0]$ sudo make install

测试一下:
    [devalone@nutch Python-3.7.0]$ python3
    Python 3.7.0 (default, Sep  6 2018, 11:51:44)
    [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux
    Type "help", "copyright", "credits" or "license" for more information.

    >>> import ssl
    >>> import uuid
    >>>

OK.


5. 升级 pip
-------------------------------------------------------------------------------------------------------------------------
[devalone@nutch Python-3.7.0]$ sudo python3 -m pip install --upgrade pip
