There’s been a few questions on setting up Apache and Mattermost, just taking this post from @alerque and making it easier to find:

<VirtualHost *:443>
    ServerName mattermost.alerque.com

    DocumentRoot /usr/share/webapps/mattermost/web

    SSLEngine on
    SSLCertificateFile    /etc/httpd/ssl.crt/alerque.com.crt
    SSLCertificateKeyFile /etc/httpd/ssl.key/alerque.com.key

    ProxyPreserveHost On

    RewriteEngine On

    RewriteCond %{REQUEST_URI}  ^/api/v1/websocket    [NC,OR]
    RewriteCond %{HTTP:UPGRADE} ^WebSocket$           [NC,OR]
    RewriteCond %{HTTP:CONNECTION} ^Upgrade$          [NC]
    RewriteRule .* ws://127.0.0.1:8065%{REQUEST_URI}  [P,QSA,L]

    RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
    RewriteRule .* http://127.0.0.1:8065%{REQUEST_URI} [P,QSA,L]
    RequestHeader set X-Forwarded-Proto "https"

    <Location /api/v1/websocket>
        Require all granted
        ProxyPassReverse ws://127.0.0.1:8065/api/vi/websocket
        ProxyPassReverseCookieDomain 127.0.0.1 mattermost.alerque.com
    </Location>

    <Location />
        Require all granted
        ProxyPassReverse http://127.0.0.1:8065/
        ProxyPassReverseCookieDomain 127.0.0.1 mattermost.alerque.com
    </Location>

    LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b" common_forwarded
    ErrorLog  /var/log/httpd/mattermost.alerque.com_error.log
    CustomLog /var/log/httpd/mattermost.alerque.com_forwarded.log common_forwarded
    CustomLog /var/log/httpd/mattermost.alerque.com_access.log combined env=!dontlog
    CustomLog /var/log/httpd/mattermost.alerque.com.log combined
</VirtualHost>
