httpd restart error : Apache

Question

When I tried to restart httpd, I am getting below error.

[admin@stg-001 ~]$ /apps/apache/bin/httpd -k restart 

httpd: Syntax error on line 114 of /apps/apache/conf/httpd.conf: Cannot load /apps/apache/modules/mod_ssl.so into server: libssl.so.1.0.0: cannot open shared object file:
No such file or directory
Server version: Apache/2.2.21 (Unix)

Please help me to resolve the error.

Answer 1

Try the following command, which shows required modules which are missing.

ldd (apache_home_dir)/modules/mod_ssl.so

Will produce something like:

linux-vdso.so.1 =>  (0x00007ffc61f7a000)        
libssl.so.1.0.0 => not found
libcrypto.so.1.0.0 => not found
librt.so.1 => /lib64/librt.so.1 (0x00007f71c9666000)

Below Fix Worked for me:

export LD_LIBRARY_PATH=/path_to_openssl/lib/

or try

export LD_LIBRARY_PATH=/path_to_openssl/

Answer 2

Why not read the error message?

Check that the line 114 of /apps/apache/conf/httpd.conf is syntatically correct

Check that the file /apps/apache/modules/mod_ssl.so exists

Answer 3

You might want to check that libssl is indeed installed on your server with the proper version. You can check in /var/lib (depends on you OS)
