I have upgraded apache httpd server from 2.4.6 to 2.4.46.
When I fire systemctl start httpd it shows the following error:

Starting httpd: /usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd:

    Make sure your apr and apr-util versions are also updated on the server and that they reside in your shared libraries.

    Try this to find what httpd has been compiled with and your current installed version.

    httpd -V | grep 'APR '; rpm -q apr apr-util

    You should then try and update either apr or apr-util accordingly.

    yum update apr apr-util

    Try again and if there is no change, update the machine fully, reboot and retry. It should work.

    Either the apr apr-util package are missing or there was corruption during the installation of these packages. Could you please reinstall apr and apr util package and test.

    I got the similar error, by backend apache is stopped because of this error
    Error: /usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_pescape_ldap

    What I have done, to resolve above issue, JUST UPDATED THE apr(Apache Portable Runtime)

    yum update apr apr_pescape_ldap -y

    Resolved my issue.
