nginx down

Pouyar69 · Jun 30, 2019

Hi guys.
sorry for my poor English.
I had a problem updating exim by custombuild and by search I realized that my problem was because of OpenSSL version and updated OpenSSL to 1.1.1
after that exim is updated with no problem but all of my websites went down with the ERR_EMPTY_RESPONSE browser response.
and now I noticed that nginx is down in my server and cant start.

DirectAdmin relies on OS version of OpenSSL, and it does not change it system-wide to a custom version. I'd suggest removing that custom installation and everything should be fine then.

Pouyar69 · Jul 1, 2019

I installed OpenSSL in this way:
https://www.osradar.com/how-to-install-the-latest-version-of-openssl-on-centos-7/

can you help me how can I remove OpenSSL?

I Tried yum remove OpenSSL and didn't work.

and when I type OpenSSL version the output is 1.1.1 and when I type yum info openssl it is 1.0.2

zEitEr · Jul 1, 2019

Hello,

Try the following

Code:

cd openssl-1.1.1/
make uninstall
ldconfig

to uninstall OpenSSL 1.1.1, then rebuild software with custombuild.

Pouyar69 · Jul 2, 2019

I uninstalled openssl and rebuilt software with custombuild but the problem exists yet.

my service nginx status output is:

Code:

Failed at step EXEC spawning /usr/sbin/nginx: No such file or directory

Either nginx is not installed, or it is installed in not-supported location.

What are the final 10-20 lines when you run ./build nginx ?

Pouyar69 · Jul 2, 2019

Thnx zEitEr.

I use nginx_apache and last lines of ./build nginx_apache is:

Code:

checking whether to enable mod_slotmem_plain... no
checking whether to enable mod_ssl... checking dependencies
checking for OpenSSL... checking for user-provided OpenSSL base directory... /usr
  setting MOD_CFLAGS to " "

*** There was an error while trying to configure Apache 2. Check the configure/ap2/configure.apache file

zEitEr · Jul 2, 2019

Code:

yum install openssl openssl-devel -y || yum reinstall -y openssl openssl-devel
ldconfig

and try again to build.

Pouyar69 · Jul 2, 2019

after
yum install openssl openssl-devel -y || yum reinstall -y openssl openssl-devel
response is:

Code:

Package 1:openssl-1.0.2k-16.el7_6.1.x86_64 already installed and latest version
Package 1:openssl-devel-1.0.2k-16.el7_6.1.x86_64 already installed and latest version
Nothing to do

and nothing changed in build.

openssl version in yum info openssl is

penssl-1.0.2k but when we try to build nginx it says checking for OpenSSL version >= 0.9.8a... FAILED.
which one is correct?

what if I try to install openssl 1.02 or 1.1 by method I tried to install 1.1.1 :

thank you very very much, Alex and nick-a.

problem with nginx has been solved by your guides.

but i have a new problem:
I cant access to my directadmin:
srv.xyz.com refused to connect.

and in my wordpress sites i have :

Code:

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define( 'WP_USE_THEMES', true );

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

Pouyar69 · Jul 3, 2019

Problem with Wordpress solved after ./build all d

But I can't access to DirectAdmin yet

zEitEr · Jul 3, 2019

As for connections to DirectAdmin kindly check: https://help.directadmin.com/item.php?id=75

'/wp-blog-header.php' );

So that means Apache is running but PHP isn't, nor is directadmin.

What's the output of

Code:

/usr/local/directadmin/directadmin

and

Code:

/usr/sbin/httpd

Do you get any errors relating to openssl libraries?

Pouyar69 · Jul 3, 2019

I had changed the directadmin port from 2222 and it was returned to 2222, I changed it and updated the directadmin licence manually and problem solved.

thanks all of you and sorry for my poor English again.
