I am trying to run Apache with SSL for my website. But when I start the Apache it throws the error saying:
httpd: Syntax error on line 127 of /usr/local/custom/apache/conf/httpd.conf:
Cannot load modules/mod_ssl.so into server: /usr/local/custom/apache/modules/mod_ssl.so:
undefined symbol: apr_global_mutex_lockfile
I also encountered the same issue. The root cause of the issue is a version mismatch in the apr version
In order to fix it, download the following: apr-util-1.5.4.tar.gz and apr-1.5.1.tar.gz. These can be downloaded at : https://apr.apache.org/download.cgi
Assuming that you have http src untarred in /src/httpd, you untar the apr-1.5.1 and apr-util in the opt/src/httpd/srclib
So the unzipped structure would be opt/src/httpd/srclib/apr and opt/src/httpd/srclib/apr-util
After this is done, you can run the configure with the following command
./configure --prefix=/opt/httpd-2.4.10 --with-included-apr make make install
This will install httpd in
You can check if the correct version of APR is referenced using the following command
You should see output as below.
