安裝libressl

cd libressl-2.7.4 ./configure --prefix=/usr/local make make install
libressl代替openssl
vim /etc/ld.so.conf.d/local.conf #新建local.conf文件，添加下面一行
/usr/local/lib # 將 /usr/local/lib 目錄加入到模塊加載目錄。
ldconfig -v #重新加載共享模塊：
openssl version #查看版本

讓python使用libressl ，修改如下源碼包中Setup.dist文件，取消如下註釋：
cd /usr/src/Python-3.7.3 ./configure --prefix=/usr/local/python make make install
vim /usr/src/Python-3.7.3/Modules/Setup.dist #_socket socketmodule.c #SSL=/usr/local #libressl的安裝目錄 #_ssl _ssl.c #-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl #-L$(SSL)/lib -lssl -lcrypto
修改默認的python版本
rm -rf /usr/bin/python #刪除/usr/bin下面python2的超鏈接 ln -s /usr/local/python/bin/* /usr/bin/ ln -s /usr/bin/python3.7 /usr/bin/python
修改下面內容，否則無法使用yum
vim /usr/bin/yum #!/usr/bin/python ==> #!/usr/bin/python2.7 vi /usr/libexec/urlgrabber-ext-down #!/usr/bin/python ==> #!/usr/bin/python2.7
如果不修改urlgrabber-ext-down文件，用yum安裝軟件時會出現下面的情況：
Error downloading packages: net-tools-2.0-0.24.20131004git.el7.x86_64: [Errno 5] [Errno 2] No such file or directory
檢測libressl和python3.7
[[email protected] pip-19.0.3]# ldd /usr/local/python/bin/python3 | fgrep ssl libssl.so.45 => /usr/local/lib/libssl.so.45 (0x00007f0636fe3000) [[email protected] pip-19.0.3]# python Python 3.7.3 (default, Apr 5 2019, 02:28:57) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import ssl >>>
安裝pip-19.0.3
[[email protected] src]# cd pip-19.0.3/ [[email protected] pip-19.0.3]# python -V Python 3.7.3 [[email protected] pip-19.0.3]# python setup.py install [[email protected] ~]# ln -s /usr/local/python/bin/pip* /usr/bin/ [[email protected] ~]# ls /usr/bin/pip* -l lrwxrwxrwx 1 root root 25 Apr 5 03:08 /usr/bin/pip -> /usr/local/python/bin/pip lrwxrwxrwx 1 root root 26 Apr 5 03:08 /usr/bin/pip3 -> /usr/local/python/bin/pip3 lrwxrwxrwx 1 root root 28 Apr 5 03:08 /usr/bin/pip3.7 -> /usr/local/python/bin/pip3.7
重啟電腦後才能使用pip install xx：
