httpd error usr/local/apache/bin/httpd: symbol lookup error: /lib/libssl.so.6: undefi

[~Phil~]

If the httpd on your centos running server gets stuck and httpd status shows you error like..

[root@server]# /etc/init.d/httpd status

Looking up localhost
Making HTTP connection to localhost
Alert!: Unable to connect to remote host.

lynx: Can't access startfile Apache Status

The apache error logs at /usr/local/apache/logs/error_log shows

/usr/local/apache/bin/httpd: symbol lookup error: /lib/libssl.so.6: undefined symbol: OPENSSL_init

It seems that the opnssl on your server is gone corrupt..
In this case what you can do is check the version of the OS running on your server with the following command

[root@server]# cat /etc/redhat-release
now go to "/usr/local/src/" directory on your server.
[root@server]# cd /usr/local/src/
Now download the latest openssl rpm
[root@server]# wget http://mirror.centos.org/centos-5/5....5_5.7.i386.rpm

Note :: in my case the OS was centos-5.6 hence the above URL worked; if you have any other version of centos then you may access the URL Index of /
and check for the rpm packge for your respective oS version.

Now remove the previously installed opnessl
[root@server]# rpm -e --nodeps openssl-0.9.8e-12.el5_5.7

To install the latest downloaded openssl rpm use the following command
[root@server]# rpm -ivh openssl-0.9.8e-12.el5_5.7.i386.rpm

Now try to restart the httpd it should work fine..

[root@server]# /etc/init.d/httpd startssl
