I am trying to start httpd server on centos 6. It throws following error :
[root#machine ~]# service httpd start
Starting httpd: (13)Permission denied: make_sock: could not bind to address [::]:88
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:88
no listening sockets available, shutting down
Unable to open logs
[FAILED]
I have also checked for port 88, It is not is use.
I also checked with semanage, but it didn't help.
Any help will be appreciated.
I happened to run into this problem because of missing SELinux permissions. By default, SELinux only allowed apache/httpd to bind to the following ports:
80, 81, 443, 488, 8008, 8009, 8443, 9000
So binding to my httpd.conf-configured Listen 88 HTTP port and config.d/ssl.conf-configured Listen 8445 TLS/SSL port would fail with that default SELinux configuration.
To fix my problem, I had to add ports 88 and 8445 to my system's SELinux configuration:
Install semanage tools: sudo yum -y install policycoreutils-python
Allow port 88 for httpd: sudo semanage port -a -t http_port_t -p tcp 88
Allow port 8445 for httpd: sudo semanage port -a -t http_port_t -p tcp 8445
Seems like you are running it not as "root". Only root can bind to this port (80).
Check your configuration in the conf/httpd.conf file, Listen line and change the port to higher one.
This is an addition to the answer by Abdull somewhere in this thread:
I had to modify instead of adding a port
semanage port -m -t http_port_t -p tcp 5000
because I get this error on adding the port
ValueError: Port tcp/5000 already defined
At terminal run this command with root permission:
sudo /etc/init.d/apache2 start
You must be root for starting a webserver otherwise you would get similar error.
With my centos 6.7 installation, not only did I have the problem starting httpd with root but also with xauth (getting /usr/bin/xauth: timeout in locking authority file /.Xauthority with underlying permission denied errors)
# setenforce 0
Fixed both issues.
Disable SELinux
Disable SELinux temporarily
sudo setenforce 0
Restart httpd service
service httpd restart
Disable SELinux persistently (after reboot)
vi /etc/selinux/config
Add line and save
SELINUX=disabled
In my case, I tried to first use port 88 instead, and even then the httpd won't start.
I used the below command, i.e. modify instead of add, as suggested by one of users, and was able to run httpd.
semanage port -a -t http_port_t -p tcp 88
after disable SELINUX, any port is aviable.
sudo -s;
setenforce 0;
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config;
In Linux(Centos 6 or higher) ports from 0 to 1024 are reserved for system use.
you can force the system to bind to address any port lower than 1024 if you use root or privileged user.
I installed Apache-2.4 from source with non-root user and I solved this problem by allowing port higher than 1024(ex:8080) and modified http.conf file. chang Listen 80 to Listen 8080
I had similar error while trying to start httpd service for openstack train installation in RHEL 7.5 too.
-- Unit httpd.service has begun starting up.

-- Subject: Unit httpd.service has failed
Solution: It got resolved by disabling SElinux.
I edited /etc/selinux/config, set SELINUX=disabled, then reboot; then it worked.
Alternately, you can run setenforce 0; you don't need reboot, but this is once used.
Just to add more info about this error, I had the similar error on CentOS 8.2:
sudo journalctl -xe
Error:
Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:8081
So, I used the commands from Abdull and Ulrich-Lorenz Schlüter as a follow:
Install semanage tools for CentOS 8.2: sudo yum -y install policycoreutils-python-utils
(For more info: https://www.cyberciti.biz/faq/redhat-install-semanage-selinux-command-rpm )
Allow port 8081 for httpd: sudo semanage port -a -t http_port_t -p tcp 8081
I got the following output: ValueError: Port tcp/8081 already defined
So, I ran:
sudo semanage port -m -t http_port_t -p tcp 8081
As Ulrich-Lorenz Schlüter mentioned.
Then: sudo systemctl start httpd
Now it is working fine.
The actual solution here is to modify the existing port if it exists. For instance, when:
semanage port -a -t http_port_t -p tcp 88
ends up with:
ValueError: Port tcp/88 already defined
then it's very likely the port is having a different type, and to modify it, simply use:
semanage port -m -t http_port_t -p tcp 88
and then, you need to open that port via firewall-cmd if has been closed in your zone.
Also: disabling SELinux is a potential security vulnerability, don't do this on production instances!
Start with root user or with sudo, it works fine, here is sample output:
[ec2-user#ip-172-31-12-164 ~]$ service httpd start
Starting httpd: (13)Permission denied: make_sock: could not bind to address [::]:80

First kill all the hanged instances of httpd, and then try restarting Apache:

I am trying to create a web server on my ubuntu 18.04 so i installed Apache2
but i can't start it.

I'm new at this can you please help me
I also faced same problem.
First check
$ sudo systemctl status nginx
If nginx is active then stop this with
$ sudo systemctl stop nginx
then again try to start apache2 server in different terminal.
first remove apache2
sudo apt-get --purge remove apache2
sudo apt-get autoremove
after that if there files (.conf) /etc/sites-available remove them using
rm example.com.conf
then install again
sudo apt-get install apache2
now it will fixed
check it now
sudo ufw allow 'Apache'
sudo systemctl status apache2
Let me give a more general answer than the first 2. One possible problem with Apache is, when we try to run it, it may fail because port 80 is used by another software:
a common case is nginx which is covered by Devashish Mishra
in my case it was a server app that I deployed (in node.js, I had to tell pm2 to stop it)
in general, you may want to find what uses port 80. This may be done like Chi.C.J.Rajeeva Lochana has suggested: install netstat if you don't have it (sudo apt install net-tools), use it: sudo netstat -antup | grep 80. It will show some lines which may include :::80 or <your IP>:80 which will tell what is listening to the port
Once you've found what listens to the 80 port, you have to decide what to do with it. For instance, if that's nginx and you don't use it, you may go like Devashish Mishra has suggested: just stop it (sudo systemctl stop nginx). Likewise, you can stop or kill (sudo killall -9 program-name) other programs. However, if you need them, you'll also need to further configure Apache and rerun them (the exact steps highly depend on the case).
Please read this carefully.
Perform the following command, and if you see it is apache, then do the following below the command.
Note: You need to install the net-tools package before you could run netstat. Run sudo apt install net-tools to install it.
sudo netstat -antup | grep 80
You should check the line with something like <Your IP>:80.
Please note that this might also happen when you uninstall Apache when it is running.
The command could be:
sudo killall -9 program-name
Replace program-name with the program's name if the program running on port 80 is not stoppable. Let me know it it doesn't work.
Thanks.
I found this problem and was able to solve it by creating a folder /var/log/apache2, I checked in the /var/log/ folder, it turns out that there is no apache2 folder, just like in the case of mysql that won't start.
seen from your log that
Feb 22 13:58:09 moment apachectl[2791]: AH00015: Unable to open logs
maybe this will help
On your terminal.
Type: sudo stop /etc/init.d/apache2
The response will be:
Stopping apache2 (via systemctl): apache2.service.
Now start the server:
sudo /opt/lampp/lampp start
If you installed lamp correctly this should work

My head is aching with finding solutions on internet. Nothing is working.
Could you guys please help me out?
Check if your firewall accepts incoming TCP connections on port 22:
# iptables -nL | grep 22
If the result is empty, you have to add a rule in your firewall.
Open Yast and firewall configuration:
# yast firewall
Goto "Allowed Services" and add "Secure Shell Server". Save and quit Yast and try to connect.
Comment: If you have disabled your firewall completly (not recommended) this answer does not apply.
Run this command:
systemctl enable sshd.service
Then make necessary changes in your /etc/ssh/sshd_config file, and start sshd via:
systemctl start sshd.service
I was dealing with the same problem in SUSE Linux Enterprise Server 15 x86-64. Within the system I was able to # ssh 127.0.0.1 (so the sshd service was working correctly), but from other nodes I got a "Timed out" message.
First, I checked the firewall rules (see answer from xloto):
# iptables -nL | grep 22
Resulted in an empty return message, so we need to set an additional rule.
To set the the firewall rule for SSH's standard port 22, I followed another tutorial (as I do not have a GUI):
# firewall-cmd --permanent --add-service=ssh
# firewall-cmd --reload
It worked for my case, but I'm not sure whether this is best practice.
I configured httpd with Chef via community httpd recipe.
https://github.com/chef-cookbooks/httpd
httpd_service "default" do
action [:create, :start]
end
After executing above code, sudo service httpd-default graceful gives the following error:
httpd: apr_sockaddr_info_get() failed for web01
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

sudo service httpd-default status says httpd is running.
How can I gracefully restart httpd manually?
My target server is CentOS 6.6.
sudo apachectl -f /etc/httpd-default/conf/httpd.conf -k graceful
this command resolved my problem.
CentOS 6.3 Minimal Configuration. Installed SSH Server, port 22. All works correctly.
I change port 22 on 777 and restart sshd and see in logs:
Jul 26 01:01:07 myserver sshd[1590]: error: Bind to port 777 on 0.0.0.0 failed: Permission denied.
Jul 26 01:01:07 myserver sshd[1590]: error: Bind to port 777 on :: failed: Permission denied.
Jul 26 01:01:07 myserver sshd[1590]: fatal: Cannot bind any address.
/etc/sysconfig/iptables contains:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 777 -j ACCEPT
netstat -tulpn | grep :22 and netstat -tulpn | grep :777 return nothing
Centos uses SELinux by default and I don't think Ubuntu does (or least I've not seen it). Have a look for SElinux permission errors in your logs too.
SELinux does not allow sshd to be run on another port on a default install of CentOS 6.3. Follow -> https://blog.tinned-software.net/change-ssh-port-in-centos-with-selinux/ :
dig a hole into your firewall (you already did that)
add a rule for SELinux to allow sshd to be run on port 777: sudo semanage port -a -t ssh_port_t -p tcp 777
you can disable selinux with command sudo setenforce 0.
sudo setenforce 0
firewall-cmd --add-port=777/tcp --permanent
firewall-cmd --reload
Port 777 is dedicated for Multiling HTTP and even though not in use you can't bind to it. If you try for example to bind to port 8777 it will work just fine.
The problem is informing SELinux, but I think there are two cases:
the port is not already allocated for a built-in service, in such case, this may work:
sudo semanage port -a -t ssh_port_t -p tcp 22777
the port is overwriting some existing service (don't ask me why); in this case this slightly different syntax is necessary:
sudo semanage port --modify -t ssh_port_t -p tcp 777
Of course, such ports should be then made available by updating the firewall:
sudo firewall-cmd --add-port=22777/tcp --permanent
or
sudo firewall-cmd --add-port=777/tcp --permanent
and then:
sudo firewal-cmd --reload
I have done "semanage port -a -t http_port_t -p tcp 81" and modified httpd.conf to listen on port 81. After restart httpd service it is not working. but it is working with default port 80. I have checked my SeLinux and it is in fact disabled. Can some one get me out of it?
Any chance you have iptables blocking port 81?
iptables -L
