# Apache



### Installer Apache (homebrew)

#### Désactiver le serveur Apache d'origine:

```bash
$ sudo apachectl stop
$ sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null
```

#### Installation:

```bash
$ brew install httpd
$ sudo brew services start httpd
```

Voir si Apache tourne:

```bash
$ ps -aef | grep httpd
  501 28356     1   0 10:56   ??         0:00.29 /opt/homebrew/opt/httpd/bin/httpd -D FOREGROUND
  501 12984   781   0  9:09   ttys001    0:00.01 tail -f /opt/homebrew/var/log/httpd/error_log
  501 29101   786   0  1:19   ttys002    0:00.00 grep httpd
```

Faire les m-à-j directement depuis Homebrew.



### Arrêter / redémarrer Apache

Apache est controllé par les *services brew*:

```bash
$ brew services stop httpd
$ brew services start httpd
$ brew services restart httpd
```

ou par *apachectl*:

```bash
$ sudo apachectl start
$ sudo apachectl stop
$ sudo apachectl -k restart
$ sudo apachectl -k restart -e Debug -E /dev/stdout
```

```http
LoadModule vhost_alias_module lib/httpd/modules/mod_vhost_alias.so
```
Mac M1
```http
# Virtual hosts
Include /opt/homebrew/etc/httpd/extra/httpd-vhosts.conf
```

Mac intel

```http
# Virtual hosts
Include /usr/local/etc/httpd/extra/httpd-vhosts.conf
```



#### Redirection:

Editer le fichier *hosts*:

```bash
$ sudo nano /etc/hosts

127.0.0.1       airbook.local
127.0.0.1       wordpress.airbook.local

127.0.0.1       zenphoto.airbook.local
127.0.0.1       phpmyadmin.airbook.local
```

Editer le fichier *httpd-vhosts.conf*:

```bash
# Mac intel
$ nano /usr/local/etc/httpd/extra/httpd-vhosts.conf

# Mac M1
$ nano /opt/homebrew/etc/httpd/extra/httpd-vhosts.conf
```

    CustomLog /usr/local/var/log/httpd/wordpress-access.log combined
    ErrorLog /usr/local/var/log/httpd/wordpress-error.log
</VirtualHost>
```

#### Redirection de port:

wiki.js tourne sur localhost:3000 

Pour le rendre disponible sur wiki.silverbook.local:

Editer le fichier *httpd.conf* et activer les modules `mod_proxy` et `mod_proxy_http`:
```http
LoadModule proxy_module lib/httpd/modules/mod_proxy.so
LoadModule proxy_http_module lib/httpd/modules/mod_proxy_http.so
```

Editer le fichier *hosts*:

```bash
$ sudo nano /etc/hosts
127.0.0.1       airbook.local
127.0.0.1       wiki.airbook.local
```

Editer le fichier *httpd-vhosts.conf*:

```http
<VirtualHost *:80>
	ServerName wiki.airbook.local
	ProxyPass / http://localhost:3000/
	ProxyPassReverse / http://localhost:3000/
	ProxyPreserveHost On
</VirtualHost>

```



### SSL:

Activer SSL dans *httpd.conf* (décocher les lignes):

```http
LoadModule socache_shmcb_module lib/httpd/modules/mod_socache_shmcb.so
...
LoadModule ssl_module lib/httpd/modules/mod_ssl.so
```

Mac M1

```http
# Secure (SSL/TLS) connections
Include /opt/homebrew/etc/httpd/extra/httpd-ssl.conf
```

Mac intel

```http
# Secure (SSL/TLS) connections
Include /usr/local/etc/httpd/extra/httpd-ssl.conf
```



Ouvrir le fichier *httpd-ssl.conf*:

```bash
# Mac intel
$ nano /usr/local/etc/httpd/extra/httpd-ssl.conf

# Mac M1
$ nano /opt/homebrew/etc/httpd/extra/httpd-ssl.conf

Rajouter ce bloc pour chaque Virtual Host.

   SSLEngine on
   SSLCertificateFile "/usr/local/etc/httpd/server.crt"
   SSLCertificateKeyFile "/usr/local/etc/httpd/server.key"
</VirtualHost>
```



### Générer un certificat auto-signé:

#### Méthode 1:

Générer la <u>clé</u> et le <u>certificat</u> (*Common Name* doit correspondre à *ServerName* du *https-vhosts.conf*)

```bash
$ cd /usr/local/etc/httpd
$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout server.key -out server.crt
```

Vérifier la configuration Apache et relancer le serveur:

```bash
$ sudo apachectl configtest
$ sudo apachectl -k restart
```

#### Méthode 2:

Installer 2 programmes:

- mkcert: Simple tool to make locally trusted development certificates
- nss: Libraries for security-enabled client and server applications (for Firefox)

```bash
$ brew install mkcert nss
```

Installer le serveur de certificat:

```bash
$ mkcert -install
Created a new local CA 💥
Sudo password:
The local CA is now installed in the system trust store! ⚡️
The local CA is now installed in the Firefox trust store (requires browser restart)! 🦊
```

Créer les dossiers pour les certificats:

```bash
$ cd /opt/homebrew/etc/httpd
$ mkdir certs && cd certs
```

Générer les certificats:

```bash
$ mkcert airbook.local

Created a new certificate valid for the following names 📜
 - "airbook.local"

The certificate is at "./airbook.local.pem" and the key at "./airbook.local-key.pem" ✅

It will expire on 29 October 2023 🗓
```

Un certificat et une clé sont créer pour chaque domaine:

```http
/opt/homebrew/etc/httpd/certs/airbook.local.pem
/opt/homebrew/etc/httpd/certs/airbook.local-key.pem
```

Editer le fichier *httpd-ssl.conf* et remplacer les 2 lignes:

```http
SSLCertificateFile "/opt/homebrew/etc/httpd/certs/airbook.local.pem"
SSLCertificateKeyFile "/opt/homebrew/etc/httpd/certs/airbook.local-key.pem"
```

Tester la configuration:

```bash
$ httpd -t
Syntax OK

$ apachectl configtest
```

Redémarrer Apache:

```bash
$ brew services restart httpd
```



#### SSL dans Virtual Host

Editer le fichier *httpd-vhosts.conf*:

Rajouter le bloc suivant

```http
<VirtualHost *:443>
    DocumentRoot "/Users/bruno/Sites"
    ServerName airbook.local
    SSLEngine on
    SSLCertificateFile "/opt/homebrew/etc/httpd/certs/airbook.local.pem"
    SSLCertificateKeyFile "/opt/homebrew/etc/httpd/certs/airbook.local-key.pem"
</VirtualHost>
```

après le bloc

### Différence installation macOS - homebrew:

***MacOS:***

```bash
/usr/sbin/httpd-wrapper

/System/Library/LaunchDaemons/org.apache.httpd.plist

/Library/WebServer/Documents/index.html

/private/etc/apache2/httpd.conf

/private/etc/apache2/extra/httpd-vhosts.conf
```

***Homebrew:***

Mac intel:

```bash
/usr/local/opt/httpd/bin/httpd

/Users/bruno/Library/LaunchAgents/homebrew.mxcl.httpd.plist
/Users/bruno/Library/LaunchAgents/homebrew.mxcl.php.plist
/Users/bruno/Library/LaunchAgents/homebrew.mxcl.mariadb.plist

/usr/local/var/www/index.html -> /Users/bruno/Sites

/usr/local/etc/httpd/httpd.conf

/usr/local/etc/httpd/extra/httpd-vhosts.conf
```

Mac M1:

```bash

/Users/bruno/Library/LaunchAgents/homebrew.mxcl.httpd.plist
/Users/bruno/Library/LaunchAgents/homebrew.mxcl.php.plist

/opt/homebrew/var/www/index.html -> /Users/bruno/Sites

/opt/homebrew/etc/httpd/httpd.conf

/opt/homebrew/etc/httpd/extra/httpd-vhosts.conf
```



### Arrêt brutal de macOS:

Il se peut qu'au redémarrage, Apache ne fonctionne plus.

Regarder *error_log*:

<!--Tue Jan 30 13:24:14.790214 2018] [core:warn][pid 2103] AH00098: pid file /usr/lo 218-->

<!--?-->

Puis arrêter et redémarrer Apache:

```bash
$ sudo apachectl stop
$ sudo apachectl start
```



### Nouvelle version de Python:

<u>Apache ne fonctionne plus</u>. Regarder *error_log*:

```http
Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
```

Dans *httpd.conf*  commencer par vérifier la version de Python dans la ligne suivante. Si elle est correcte, commenter la ligne:

`WSGIPythonHome "/usr/local/Cellar/python/3.6.4_4/Frameworks/Python.framework/Versions/3.6"`

Arrêter et redémarrer Apache.

Si cela refonctionne, désinstaller et réinstaller <u>mod_wsgi</u> avec <u>pip</u>.

```bash
$ pip3 list --format=columns
