ubuntu/apache2 container crashes with error: serverroot must be a valid directory

[Eagle_B5]

Hi community,

I'm quite new to the container topic on Synology, so I have a few questions about my issue.

A bit more context on the use-case: I intend to run an Apache2 instance as a container, which is more customizable than the native Apache2 package. Because the native package has content compression enabled by default, and I didn't find a way to disable compression for already compressed files (e.g. tgz).
Long story short, I found that the ubuntu/apache2 image from Docker Hub seems suitable for my use case.

The image has been downloaded in Container Manager and a container has been spun up with the following folder/file mappings (apache2.conf exists in the Syno folder):

• /volume1/docker/<name>/html:/var/www/html:ro
• /volume1/docker/<name>/apache2/apache2.conf:/etc/apache2/apache2.conf:ro

My issue, the container crashes immediately with the error: apache2: Syntax error on line 34 of /etc/apache2/apache2.conf: ServerRoot must be a valid directory

Does someone know what I did wrong?

Welcome.

My issue, the container crashes immediately with the error: apache2: Syntax error on line 34 of /etc/apache2/apache2.conf: ServerRoot must be a valid directory

And what is the actual line 34 of that file? Server root value is what?

Please don't make us guess how your apach2.conf looks like. Please share it in a code block.

Apologies for my delayed answer. Indeed, it was a mistake in the apache2.conf for ServerRoot. Thanks for this hint. Now it is working with this conf:

Mutex file:${APACHE_LOCK_DIR} default
PidFile ${APACHE_PID_FILE}
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
HostnameLookups Off
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
IncludeOptional mods-enabled/*.load
IncludeOptional mods-enabled/*.conf
Include ports.conf
ServerName depot.ksc.lab
ServerAdmin [email protected]
    <Directory /var/www/html>
        Options +Indexes +FollowSymLinks
        IndexOptions +FoldersFirst
        AllowOverride All
        Require all granted
    </Directory>
AccessFileName .htaccess
<FilesMatch "^\.ht">
        Require all denied
</FilesMatch>
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
IncludeOptional conf-enabled/*.conf
IncludeOptional sites-enabled/*.conf

.htaccess and .htpasswd is located in a subfolder that makes it password protected. That works now fine as well.

Glad that it is fixed now, and thank you for sharing it!
