\"Configurando
\n
\nNeste artigo, apresentaremos um guia detalhado sobre a instala\u00e7\u00e3o e configura\u00e7\u00e3o dos programas Apache, Python e PostgreSQL para garantir o funcionamento de um projeto Django no sistema operacional MS Windows. O Django j\u00e1 inclui um servidor de desenvolvimento simplificado para testes locais de c\u00f3digo, mas para tarefas relacionadas a produ\u00e7\u00e3o, \u00e9 necess\u00e1rio um servidor web mais seguro e poderoso. Vamos configurar o mod_wsgi para interagir com nosso projeto e configuraremos o Apache como um gateway para o mundo exterior.<\/p>\n

Vale destacar que a instala\u00e7\u00e3o e configura\u00e7\u00e3o ser\u00e3o realizadas no sistema operacional MS Windows 10 de 32 bits. Al\u00e9m disso, a vers\u00e3o de 32 bits ser\u00e1 universal e funcionar\u00e1 em arquiteturas de 64 bits. Se voc\u00ea precisar de uma instala\u00e7\u00e3o de 64 bits, repita as mesmas etapas para os pacotes de 64 bits, a sequ\u00eancia de a\u00e7\u00f5es ser\u00e1 id\u00eantica.
\n<\/a><\/noindex>
\nComo projeto Django, usaremos o programa Severcart. Ele \u00e9 destinado \u00e0 gest\u00e3o do movimento de cartuchos, controle de equipamentos de impress\u00e3o e contratos de fornecimento e manuten\u00e7\u00e3o. A instala\u00e7\u00e3o de todos os programas e m\u00f3dulos ser\u00e1 feita no diret\u00f3rio C:severcart. A localiza\u00e7\u00e3o n\u00e3o \u00e9 fundamental.<\/p>\n

Python<\/h2>\n

\nO primeiro passo \u00e9 baixar e instalar o Python do site oficial. Selecione Windows como sistema operacional e a vers\u00e3o de 32 bits. No momento da reda\u00e7\u00e3o deste artigo, a vers\u00e3o atual \u00e9 3.9.0rc2. <\/p>\n

Ap\u00f3s baixar o arquivo de instala\u00e7\u00e3o, clique com o bot\u00e3o direito no arquivo e selecione \u2018Executar como administrador\u2019. Voc\u00ea dever\u00e1 ver a tela abaixo.<\/p>\n

\"Configurando
\n
\nMarque as caixas \u2018Install launcher for all users (recomended)\u2019 e \u2018Add Python 3.9 to PATH\u2019 e clique em \u2018Customize installation\u2019. <\/p>\n

\"Configurando
\n
\nMarque as caixas \u2018pip\u2019, \u2018py launcher\u2019, \u2018for all users (requires elevation)\u2019 e clique em \u2018Next\u2019. <\/p>\n

\"Configurando
\n
\nSelecione todos os campos de entrada como na imagem acima e clique em \u2018Install\u2019.<\/p>\n

\"Configurando
\n
\nPara verificar se a instala\u00e7\u00e3o foi bem-sucedida, abra o cmd e digite python. Se a instala\u00e7\u00e3o foi bem-sucedida, voc\u00ea dever\u00e1 ver um prompt semelhante ao mostrado abaixo.<\/p>\n

\"Configurando
\n<\/p>\n

Instalando mod_wsgi<\/h2>\n

\nBaixe o pacote compilado do mod_wsgi no site
\nwww.lfd.uci.edu\/~gohlke\/pythonlibs<\/a><\/noindex>O m\u00f3dulo atua como intermedi\u00e1rio entre o servidor Apache e o projeto Django. O pacote mais recente ser\u00e1 nomeado mod_wsgi-4.7.1-cp39-cp39-win32.whl. Observe que o pacote foi compilado para Windows CPython de 32 bits com a vers\u00e3o 3.9. Tamb\u00e9m \u00e9 importante notar que a instala\u00e7\u00e3o do m\u00f3dulo via pip install mod_wsgi provavelmente resultar\u00e1 em erro, pois ser\u00e1 necess\u00e1rio um compilador Visual Studio C++ durante o processo de instala\u00e7\u00e3o. Consideramos desnecess\u00e1rio instalar o compilador apenas para um pacote Python no Windows.<\/p>\n

Instalamos o m\u00f3dulo usando o gerenciador de pacotes padr\u00e3o pip no cmd ou powershell:<\/p>\n

pip install -U mod_wsgi-4.7.1-cp39-cp39-win32.whl\n<\/code><\/pre>\n
\"Configurando
\n<\/p>\n
Apache<\/h2>\n
\nBaixamos o distribuidor do site https:\/\/www.apachelounge.com\/download\/<\/a><\/noindex>.
\nA vers\u00e3o mais recente do servidor web \u00e9 Apache 2.4.46 win32 VS16. Tamb\u00e9m ser\u00e1 necess\u00e1rio ter previamente instalado o pacote \"Visual C++ Redistributable for Visual Studio 2019 x86\" para que o programa funcione.<\/p>\n
Descompactamos o distribuidor do Apache no diret\u00f3rio C:severcartApache24, em seguida, alteramos a linha n\u00famero 37 para o nosso pr\u00f3prio. <\/p>\n
Defina SRVROOT \"C:\/severcart\/Apache24\"\n<\/code><\/pre>\n
Verificamos o funcionamento do Apache, executando no prompt de comando.<\/p>\n
C:\/severcart\/Apache24\/bin> httpd.exe\n<\/code><\/pre>\n
Como resultado, devemos ver no navegador no endere\u00e7o 127.0.0.1<\/a><\/noindex> a linha \"It works!\".<\/p>\n
\"Configurando
\n
\nInstalamos o servi\u00e7o Apache, para isso executamos no prompt de comando como Administrador o seguinte comando:<\/p>\n
C:severcartApache24bin>httpd.exe -k install -n \"Apache24\"\n<\/code><\/pre>\n
Em seguida, conectaremos o m\u00f3dulo mod_wsgi ao Apache. Para isso, executamos no prompt de comando o comando<\/p>\n
C:Windowssystem32>mod_wsgi-express module-config\n<\/code><\/pre>\n
Como resultado, as seguintes linhas ser\u00e3o impressas na sa\u00edda padr\u00e3o:<\/p>\n
LoadFile \"c:\/severcart\/python\/python39.dll\"\nLoadModule wsgi_module \"c:\/severcart\/python\/lib\/site-packages\/mod_wsgi\/server\/mod_wsgi.cp39-win32.pyd\"\nWSGIPythonHome \"c:\/severcart\/python\"\n<\/code><\/pre>\n
Criamos o arquivo C:severcartApache24confextrahttpd-wsgi.conf e colamos as linhas impressas acima.<\/p>\n
Conectamos a nova configura\u00e7\u00e3o ao arquivo principal httpd.conf
\nInclude conf\/extra\/httpd-wsgi.conf<\/p>\n
Salvamos as altera\u00e7\u00f5es e reiniciamos os servi\u00e7os do Apache.<\/p>\n
Net stop Apache24\nNet start Apache24\n<\/code><\/pre>\n
PostgreSQL<\/h2>\n
\nInstalamos o PostgreSQL obtido do site https:\/\/postgrespro.ru\/windows<\/a><\/noindex>. A vers\u00e3o atual do produto \u00e9 12. As vantagens da distribui\u00e7\u00e3o russa em rela\u00e7\u00e3o \u00e0 can\u00f4nica est\u00e3o apresentadas no mesmo site.<\/p>\n

Criamos um banco de dados no postgres, onde mais tarde ser\u00e3o armazenadas as estruturas de dados do projeto Django.<\/p>\n
C:severcartpostgresqlbin>psql -h 127.0.0.1 -U postgres -W\n\nCREATE DATABASE severcart WITH ENCODING='UTF8' OWNER=postgres CONNECTION LIMIT=-1 template=template0;\n<\/code><\/pre>\n

\nO banco de dados foi criado. Agora vamos implantar o projeto Django.<\/p>\n
Instalamos o aplicativo web.<\/h2>\n
\nPara isso, baixamos o arquivo zip do site. https:\/\/www.severcart.ru\/downloads\/<\/a><\/noindex> e descompactamos no diret\u00f3rio C:severcartapp<\/p>\n
\"Configurando
\n
\nFazemos altera\u00e7\u00f5es no arquivo de configura\u00e7\u00e3o principal C:severcartappconfsettings_prod.py para indicar as credenciais de conex\u00e3o com o banco de dados<\/p>\n

Instalamos pacotes Python necess\u00e1rios para o funcionamento das aplica\u00e7\u00f5es dentro do projeto Django<\/p>\n

\nDurante a execu\u00e7\u00e3o do script, a inicializa\u00e7\u00e3o do banco de dados ser\u00e1 realizada com tabelas, constraints, \u00edndices e outros elementos, sendo solicitado a cria\u00e7\u00e3o de um usu\u00e1rio, que ser\u00e1 utilizado para operar o programa.<\/p>\n
Conectamos a aplica\u00e7\u00e3o Django ao servidor Apache, para isso, complementamos o arquivo de configura\u00e7\u00e3o 
\nhttpd-wsgi.conf com o seguinte texto<\/p>\n
Alias \/static \"c:\/severcart\/app\/static\"\n\nAlias \/media \"c:\/severcart\/app\/media\"\n\n\n    # para Apache 2.4\n    Options Indexes FollowSymLinks\n    AllowOverride None\n    Require all granted\n\n\n\n    # para Apache 2.4\n    Options Indexes FollowSymLinks\n    AllowOverride None\n    Require all granted\n\n\n\nWSGIScriptAlias \/ \"c:\/severcart\/app\/conf\/wsgi_prod.py\"\nWSGIPythonPath \"c:\/severcart\/python\/\"\n\n\n\n    Require all granted\n\n<\/code><\/pre>\n
\nReiniciamos o servi\u00e7o Apache e verificamos o funcionamento da aplica\u00e7\u00e3o<\/p>\n

\nIsso \u00e9 tudo. Obrigado por ler.<\/p>\n
No pr\u00f3ximo artigo, vamos criar um instalador autoextra\u00edvel em InnoSetup para a implanta\u00e7\u00e3o r\u00e1pida do projeto Django no computador do cliente. Para aqueles que desejam repetir todas as etapas em Yandex.Disk<\/a><\/noindex> todos os pacotes utilizados foram carregados.
