CentOS/Redhat 部署：

a，先确保OpenSSL版本大于1.0.1 ############################################################ rpm -qa | grep openssl wget http://www.openssl.org/source/openssl-1.0.2j.tar.gz tar -xzvf openssl-1.0.2j.tar.gz cd openssl-1.0.2j ./config --prefix=/usr/local/openssl shared zlib make && make install echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openssl/lib" >> /etc/profile source /etc/profile mv /usr/bin/openssl /usr/bin/openssl.old mv /usr/include/openssl /usr/include/openssl.old ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl ln -s /usr/local/openssl/include/openssl /usr/include/openssl ln -s /usr/local/openssl/lib/libssl.so /usr/local/lib64/libssl.so strings /usr/local/lib64/libssl.so |grep OpenSSL echo "/usr/local/openssl/lib" >> /etc/ld.so.conf ldconfig /etc/ld.so.conf ldconfig -v ############################################################

b，下载编译安装Python3和PIP3 ############################################################ yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel libffi-devel expat-devel gdbm-devel readline-devel gcc gcc-c++ python-devel.x86_64 # 安装python3依赖库 rpm -ivh libffi-devel-3.0.13-18.el7.x86_64.rpm wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz tar -zxvf Python-3.7.0.tgz cd echo Python-3.7.0.tgz |awk 'BEGIN{FS="/"}''{print $NF}'| awk -F".tgz" '{print $NR}' ./configure --prefix=/data/ioszdhyw/soft/python3_7 --with-openssl=/usr/local/openssl # 指定编译安装位置 make && make install # 编译安装 ln -s /data/ioszdhyw/soft/python3_7/bin/python3 /usr/bin/python3 # 创建python3软链接 ln -s /data/ioszdhyw/soft/python3_7/bin/pip3 /usr/bin/pip3 # 创建pip3软链接 ############################################################

1，安装requirements文件：pip install -r requirements.txt 2，安装uWSGI必要安装：yum install python-devel.x86_64 3，pip升级包：pip3 install --upgrade django 4，升级pip：python3 -m pip3 install --upgrade pip3 5，查询pip版本：pip3 -V
