Linux部署Django遇到的問題

安裝Python3

Notes：操作系統：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，報錯了！！

各種報錯

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

Solution: 缺少包，下載安裝
yum install zli*

---

• Error: Multilib version problems found.

Solution: 發現了多個版本，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

將原來 python 的軟鏈接重命名：
mv /usr/bin/python /usr/bin/python.bak

將 python 鏈接至 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.

該錯誤在執行 pip install django 時出現。

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

裝完後，重新編譯安裝Python
cd Python-3.6.3
./configure --with-ssl
make && make install

---

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

該錯誤在執行 yum install openssl-devel 時出現。

cd /usr/bin/
ls -l python*

Solution: yum安裝軟件時，需要Python的支持，默認爲Python2

vim /usr/bin/yum
vim /usr/libexec/urlgrabber-ext-down
將#! /usr/bin/python 改爲 #! /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

該錯誤在執行 yum install mysql-devel gcc gcc-devel python-devel --skip-broken 時出現。

Solution: 版本衝突，列出所有的版本，移除沒用的版本

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

該錯誤在執行 pip install mysqlclient 時出現。

Solution: 主要是倉庫裏沒有mysql的源。。先移除，再安裝

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
CentOS-Base.repo         CentOS-Debuginfo.repo  CentOS-Media.repo

[root@rabbitmq yum.repos.d]# rpm -ivh http://repo.mysql.com/mysql57-community-release-el7-7.noarch.rpm

CentOS-CR.repo           CentOS-fasttrack.repo  CentOS-Vault.repo

終於沒有錯誤了，啓動。。

pip install mysqlclient
python manage.py runserver
