I had a hard time so I made a note.
--Create a virtual CentOS8 environment using VMware and build a Web server there.
--The Django project has been created. Use a shared folder or FTP to go to CentOS (this time / var / www / projectname /) together with the project folder.
$ dnf list | grep httpd
Besides httpd body
You can see that there are such things. Install these together with the main unit as you will need them in the future.
$ dnf -y install httpd httpd-tools httpd-devel httpd-manual
$ dnf list --installed | grep httpd #Check if it is installed
$ systemctl start httpd
$ systemctl status httpd #Check if Apache can be started
$ systemctl enable httpd #Enable automatic startup
$ firewall-cmd --add-service=http --zone=public --permanent
$ firewall-cmd --reload
$ firewall-cmd --list-all #Check if http is added to services
First, access http: // localhost /. OK if the Apache test page is displayed. Next, place the HTML file and check if it is displayed.
$ touch /var/www/html/index.html
$ vi /var/www/html/index.html #Write appropriate HTML
If you access http: // localhost / and HTML is displayed, it's OK.
Try to specify the domain using / etc / hosts.
$ vi /etc/hosts #127.0.0.Example on line 1.add com
$ mkdir /var/www/example.com
$ touch /var/www/example.com/index.html
$ vi /var/www/example.com/index.html #Write appropriate HTML
Edit Apache conf. Since we plan to use SSL or use multiple domains later, set it as VirtualHost.
$ touch /etc/httpd/conf.d/virtual.conf
$ vi /etc/httpd/conf.d/virtual.conf
$ service httpd configtest #You can check the syntax of the configuration file
conf:/etc/httpd/conf.d/virtual.conf
<VirtualHost *:80>
DocumentRoot /var/www/example.com
ServerName example.com
<Directory "/var/www/example.com">
Require all granted
</Directory>
</VirtualHost>
At the time of config test
Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
When appears, specify the ServerName in httpd.conf as you were told.
/etc/httpd/conf/httpd.conf (around lines 98-99)
ServerName example.com:80
Finally restart Apache and check the operation
$ systemctl restart httpd
Now when you visit http: // localhost / or http://example.com you will see /var/www/example.com/index.html.
$ dnf -y install git #Install git to do a git clone
$ git clone https://github.com/pyenv/pyenv.git /var/www/pyenv
$ vi ~/.bash_profile #Add the following
~/.bash_profile (additional note)
export PYENV_ROOT="/var/www/pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
Initially, the installation destination of pyenv was /root/.pyenv, but if it is below the root, it seems that it can be accessed only with root authority (Apache can not be accessed), so Apache has the authority to install/ Re-installed under var / www /.
source ~/.bash_profile #Apply bash
pyenv --version #Operation check
From here, we will proceed while correcting the trajectory while issuing an error, so if you are going to practice this procedure, we recommend that you read it to the end and then try it.
First, try installing Python normally
$ pyenv install 3.x.x
Then I got an error like this.
zipimport.ZipImportError: can't decompress data; zlib not available
So install zlib.
$ dnf -y install zlib zlib-devel
Perhaps zlib is already installed. I have to install some packages in the future, but I also need to install -devel together with the main body.
I regain my mind and install Python, but I get an error again.
(Excerpt)
WARNING: The Python bz2 extension was not compiled. Missing the bzip2 lib?
WARNING: The Python readline extension was not compiled. Missing the GNU readline lib?
ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?
There are ERROR and WARNING, but both need to be resolved in the end, so install the missing package.
python
$ dnf -y install bzip2 bzip2-devel readline readline-devel openssl openssl-devel
Install Python again. It succeeds, but a warning is given.
WARNING: The Python sqlite3 extension was not compiled. Missing the SQLite3 lib?
This will also be a problem later, so install it.
$ dnf -y install sqlite sqlite-devel
Now Python is finally installed.
pyenv versions #3.x.Make sure x is installed
pyenv global 3.x.x #Apply Python version to the whole
python --version #3.x.Confirm that x works
#Also update and check pip
pip install --upgrade pip
pip --version
pip install django
It's easy to forget.
mod_wsgi is obtained by wget from Download files of PyPI. It seems that there are various ways to obtain mod_wsgi, but for the time being, I have succeeded in this method, so I will describe it.
$ cd /var/www/
$ wget https://files.pythonhosted.org/packages/...Abbreviation.../mod_wsgi-x.x.x.tar.gz
$ tar -zxvf mod_wsgi-x.x.x.tar.gz
$ cd mod_wsgi-x.x.x/
$ ./configure --with-python=/var/www/pyenv/versions/3.x.x/bin/python
When I try to type the make command here, I get the following error:
error: /usr/lib/rpm/redhat/redhat-hardened-cc1:There is no such file or directory
So install redhat-rpm-config again.
$ dnf -y install redhat-rpm-config
When I run make`` make install again, I get the following error
'xxx' can not be used when making a shared object; recompile with -fPIC
This error can be resolved by adding CFLAGS =" -fPIC " when installing Python. So I reinstalled Python.
$ CFLAGS="-fPIC" pyenv install 3.x.x
$ make
$ make install
This will generate /etc/httpd/modules/mod_wsgi.so.
Finally, the WSGI installation is complete, so put the project file as / var / www / projectname, edit the Apache settings again, and restart.
conf:/etc/httpd/conf.d/virtual.conf
LoadModule wsgi_module /etc/httpd/modules/mod_wsgi.so
WSGIPythonHome /var/www/pyenv/versions/3.x.x
WSGIPythonPath /var/www/pyenv/versions/3.x.x/lib/python3.x/site-packages
WSGIPythonPath /var/www/projectname
<VirtualHost *:80>
DocumentRoot /var/www/projectname
ServerName example.com
WSGIScriptAlias / /var/www/projectname/projectname/wsgi.py
<Directory "/var/www/projectname">
Require all granted
</Directory>
#Collect static on the django project side
Alias /static/ /var/www/projectname/static/
<Directory "/var/www/projectname/static">
Require all granted
</Directory>
</VirtualHost>
WSGIPythonHome is a Python script that sys.prefix points to.
One of the WSGIPythonPath is the sys.path that ends with site-packages. The other is the home directory of the Django project, which seems to need to be described both.
From here, proceed while checking the error below.
tail /etc/httpd/logs/error_log
The following error will appear immediately, so take action.
failed to map segment from shared object
Unable to configure formatter 'django.server'
These can be resolved by disabling SELinux and making the owner and group of files under / var / www / apache.
setenforce 0
chown -R apache:apache /var/www/
After restarting Apache, you should see your Django project at http: // localhost.
When I access http://example.com, I get a DisallowedHost error on the Django side, but as the error message says, I can see it by adding ʻexample.com to ʻALLOWED_HOSTS in settings.py.
