本文档详细介绍了在Linux环境中手动安装LibreSSL 2.7.4和Python 3.7的过程，包括依赖库的安装、配置、编译和环境变量设置。首先通过yum安装必要的依赖，接着下载并编译LibreSSL，更新环境变量。然后下载Python 3.7源码，进行编译和安装。完成这些步骤后，系统将具备运行Python 3.7的能力。

1.安装依赖环境

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

2.安装libressl2.74

wget https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-2.7.4.tar.gz --no-check-certificate
tar zxvf libressl-2.7.4.tar.gz 
cd libressl-2.7.4   
./configure --prefix=/usr/local/libressl274
make 
make install

在.bash_profile增加以下代码

export LDFLAGS="-L/usr/local/libressl274/lib"
export CPPFLAGS="-I/usr/local/libressl274/include -I/usr/local/libressl274/include/openssl"
export PKG_CONFIG_PATH=”/usr/local/libressl274/lib/pkgconfig”
export LD_LIBRARY_PATH="/usr/local/libressl274/lib:$LD_LIBRARY_PATH"
 export PATH="/usr/ocal/python37/bin:$PATH"

然后source .bash_profile

在/etc/ld.so.conf.d 目录下新建一个文件libressl274.conf
内容为
/usr/local/libressl274/lib
保存后执行
ldconfig -v

3.下载python源码包

wget https://www.python.org/ftp/python/3.7.8/Python-3.7.8.tgz

4.编译安装python3.7

tar zxvf Python-3.7.8.tgz
cd Python-3.7.8
./configure prefix=/usr/ocal/python37
make
make install
