Linux部署Django遇到的问题

安装Python3

Notes：操作系统：CentOS7

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
tar -xvf Python-3.6.3.tar.xz
cd Python-3.6.3
./configure
make && make install

然而，报错了！！

各种报错

• zipimport. ZipImportError: can’t decompress data; zlib not available

Solution: 缺少包，下载安装 yum install zli*

• Error: Multilib version problems found.

Solution: 发现了多个版本，忽略 yum install -y zlib zlib-devel –setopt=protected_multilib=false

cd Python-3.6.3
./configure
make && make install

成功： Collecting setuptools Collecting pip Installing collected packages: setuptools, pip Successfully installed pip-9.0.1 setuptools-28.8.0

将原来 python 的软链接重命名： mv /usr/bin/python /usr/bin/python.bak

将 python 链接至 python3： ln -s /usr/local/bin/python3 /usr/bin/python

• pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

该错误在执行 pip install django 时出现。

Solution: 不支持 SSL，安装 openssl-devel yum install openssl-devel

装完后，重新编译安装Python cd Python-3.6.3 ./configure –with-ssl make && make install

• File “/usr/bin/yum”, line 30 except KeyboardInterrupt, e:

该错误在执行 yum install openssl-devel 时出现。

cd /usr/bin/ ls -l python*

Solution: yum安装软件时，需要Python的支持，默认为Python2

vim /usr/bin/yum
vim /usr/libexec/urlgrabber-ext-down
将#! /usr/bin/python 改为 #! /usr/bin/python2

• Found 1 pre-existing rpmdb problem(s), ‘yum check’ output follows:zlib-1.2.7-18.el7.x86_64 is a duplicate with zlib-1.2.7-13.el7.i686

该错误在执行 yum install mysql-devel gcc gcc-devel python-devel --skip-broken 时出现。

Solution: 版本冲突，列出所有的版本，移除没用的版本

rpm -qa | grep zlib

    zlib-1.2.7-18.el7.x86_64
    zlib-devel-1.2.7-18.el7.x86_64
    zlib-1.2.7-13.el7.i686

yum remove zlib-1.2.7-13.el7.i686

• OSError: mysql_config not found

该错误在执行 pip install mysqlclient 时出现。

Solution: 主要是仓库里没有mysql的源。。先移除，再安装

yum -y remove mysql57-community-release-el7-7.noarch
[root@rabbitmq yum.repos.d]# cd /etc/yum.repos.d/
[root@rabbitmq yum.repos.d]# ls

终于没有错误了，启动。。

pip install mysqlclient
python manage.py runserver
