(98)Address already in use: make_sock: could not bind to address 0.0.0.0:1212

nagendrar · 05-15-2018, 08:39 AM

I have configured custom port and I have configured certificates properly.
But my http server is failing to start and getting error as below.

Code:

 /etc/init.d/httpd start
Starting httpd: [Tue May 15 15:25:53 2018] [warn] _default_ VirtualHost overlap on port 9216, the first has precedence
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:1212
no listening sockets available, shutting down
Unable to open logs

I tried for the pid of http and tool which was already listening on 1212 as below commands. But not find any pid.

Code:

ps -aux |grep httpd

lsof -i tcp:1212

Part of my http conf file looks as below:

Code:

Listen 1212
<VirtualHost *:1212>
Timeout 3000
SSLEngine ON
SSLCertificateFile /var/aaa/conf/aaa.cer
SSLCertificateKeyFile /var/aaa/conf/aaa.key

LoadModule perl_module "/var/aaa/conf/mod_perl.so"
DocumentRoot "/var/aaa"

Please help me to find possible reason and to fix the issue.

The server cannot bind to address 0.0.0.0 because it is a special IP address meaning broadcast, or all stations. You cannot bind to a non-address on your system. Your system needs to have an actual real unicast IP address to bind services to.

What's the output of

#httpd -D DUMP_VHOSTS
or
#httpd -S
(No idea if these are distro specific. Mine is CentOS, so ymmv)

Also, if you have SELinux enforced, have you set the correct context ?
#semanage port -l | grep 'your_port'

Also, check this to see if your port is already being used-
#fuser -n tcp 'your_port'

Edit - WRT what rtmistler said above, absolutely correct. Make http listen to a specific network/interface first.
in httpd.conf you should see something similar to -
#Listen 12.34.56.78:80

Also,a simple web-search gave me this and multiple references to stackoverflow.

Thanks for replies. But not solved my problem. My machine is centos6.9.

I can definitely say that 1212 port is not using by any application.
But I am getting below issue

Code:

[root@aaa~]# /etc/init.d/httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:1212
no listening sockets available, shutting down
Unable to open logs
                                                     [FAILED]

As I mentioned in my first comment, I am getting empty output for below commands:

Code:

ps -aux |grep httpd

lsof -i tcp:1212

Is there any other possible reason/solutions? Please help me to fix the issue.

Unless you mention what you have tried so far, or provide the O/Ps, there's nothing a bunch of volunteers can do.

You may have more than one "Listen 1212" directive in your apache config.
You may run the following command and find all the "Listen ..." directives:

Code:

grep -ri ^Listen /etc/httpd/

Also check the apache error_log to see if you find anything

In this context 0.0.0.0 means all IPv4 addresses on the local machine. To see how the servers are configured to listen run the command as root
netstat -tulpn

Not an apache expert by any means and you did not post enough of your configuration file but I believe you need a NamedVirtualHost line.

Got the reason. We have "Include conf.d/*.conf" condition in httpd.conf file and we have our custom http backup file with '.conf' extension is available in /etc/httpd/conf.d.

Issue was fixed after renaming it.
Thanks for responses.

Glad it's sorted. Please mark the thread as solved.
