check_http: Invalid option - SSL is not available

[dragan979]

I installed Nagios core 4.5.4 and compiled nagios plugin 2.1.2 on CentOS 8.

Code: Select all

dnf install openssl-devel openssl 
Last metadata expiration check: 1:19:02 ago on Wed 13 Nov 2019 12:56:30 PM CET.
Package openssl-devel-1:1.1.1-8.el8.x86_64 is already installed.
Package openssl-1:1.1.1-8.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!

Then compiled plugin

Code: Select all

./configure --with-openssl --with-nagios-user=nagios --with-nagios-group=nagios

Output is that openssl is set to NO

Code: Select all

config.status: creating po/Makefile

              --with-ping6-command: /sbin/ping6 -n -U -w %d -c %d %s
               --with-ping-command: /sbin/ping -n -U -w %d -c %d %s
                       --with-ipv6: yes
                      --with-mysql: no
                    --with-openssl: no
                     --with-gnutls: no
               --enable-extra-opts: yes
                       --with-perl: /bin/perl
             --enable-perl-modules: no
                     --with-cgiurl: /nagios/cgi-bin
               --with-trusted-path: /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
                   --enable-libtap: no

I want to check SSL expiration date:

Code: Select all

/usr/local/nagios/libexec/check_http -H 1.1.1.1 -S                                                           
check_http: Invalid option - SSL is not available
Usage:
 check_http -H <vhost> | -I <IP-address> [-u <uri>] [-p <port>]
       [-J <client certificate file>] [-K <private key>]
       [-w <warn time>] [-c <critical time>] [-t <timeout>] [-L] [-E] [-a auth]
       [-b proxy_auth] [-f <ok|warning|critcal|follow|sticky|stickyport>]
       [-e <expect>] [-d string] [-s string] [-l] [-r <regex> | -R <case-insensitive regex>]
       [-P string] [-m <min_pg_size>:<max_pg_size>] [-4|-6] [-N] [-M <age>]
       [-A string] [-k string] [-S <version>] [--sni] [-C <warn_age>[,<crit_age>]]
       [-T <content-type>] [-j method]

Can anyone guide me in right direction ?.

Thanks in advance.

After many failed attempts, finally found solution:

Code: Select all

cd /tmp
wget --no-check-certificate -O nagios-plugins.tar.gz https://github.com/nagios-plugins/nagios-plugins/archive/release-2.2.1.tar.gz
tar zxf nagios-plugins.tar.gz
cd /tmp/nagios-plugins-release-2.2.1/
./tools/setup
./configure --with-openssl --with-nagios-user=nagios --with-nagios-group=nagios
make
make install

Finally got yes for enable ssl, and error is gone.
