How to check if mod_alias is enabled?

Question

I have a gatsby page which has 2 columns of equal width, a header on top, and a footer at the bottom. I have some content in the left column and an image in the right column. I am using graphql to query an fluid image. I set the maxWidth property but when the page loads, the image is still of original size, roughly 700 x 800. Any help in what is causing this would be greatly appreciated as i am still new to gatsby. Thank you.

const About = (props) => {
  return (
    <Layout>
      <Row className={aboutStyles.padding}>
        <Col>
          <h1 className="text-center">Test Page</h1>
          <div>
            <p>This is the left column</p>
          </div>
        </Col>
        <Col>
          <Img fluid={props.data.dumpTruck.childImageSharp.fluid} />
        </Col>
      </Row>
    </Layout>
  )
}

export default About

export const pageQuery = graphql`
  query {
    dumpTruck: file(relativePath: { eq: "dumpTruck.jpg" }) {
      childImageSharp {
        fluid(maxWidth: 400) {
          ...GatsbyImageSharpFluid
        }
      }
    }
  }

Solution 1

You can check if mod_alias is enabled by using the following command:

~$ apache2ctl -M | grep alias

If it's enabled, it will give you the following response:

 alias_module (shared)
Syntax OK

You can also check manually the file which is loading the module:

~$ cat /etc/apache2/mods-enabled/alias.load 

If it's enabled, it will give you the following response:

LoadModule alias_module /usr/lib/apache2/modules/mod_alias.so

Solution 2

You can try listing all active modules with one of these:

apachectl -t -D DUMP_MODULES

or

httpd -M

Also, check if the module is commented out in the httpd.conf file:

cat /etc/httpd/conf/httpd.conf | grep LoadModule

I have moved on from Gatsby/GraphQL as I wasn't able to resolve this.

Hi, Gabriel. I am getting '-bash: apachectl: command not found'. Nevermind, the 'httpd -M' command worked

When running 'cat /etc/httpd/conf/httpd.conf | grep LoadModule' I am getting 'LoadModule bwlimited_module modules/mod_bwlimited.so'

[Knocks X]

-bash: apache2ctl: command not found

cat: /etc/apache2/mods-enabled/alias.load: No such file or directory

[Knocks X]

-bash: LoadModule: command not found

you can try httpd -M | grep alias

httpd -M | grep alias Syntax OK alias_module (static) - Does that mean it's on?
