Fix error retrieving pid file on termux apache

Solution to "error retrieving pid file" - Termux and apache

Apache errors overview:

      (20014) Internal error (specific information not available):

      AH00058: Error retrieving pid file var / run / apache2 / httpd.pid

      AH00059: Remove it before continuing if it is corrupted.
    

This mistake seems while summoning apachectl either with start or with stop and here and there happens when running on Previous Install XAMPP apache on android termux.

Solution

• Stop apache first

  apachectl stop

• Change dir:

  cd /data/data/com.termux/files/usr/var/run/apache2

• Then delete the httpd.pid file:

  rm httpd.pid

• Or using this script:

            aps=$(pidof httpd)
            pidf=/var/run/apache2/httpd.pid
            [[ -f $pidf ]] && rm -f $pidf
            [[ "$aps" != "" ]] && kill -9 $aps
