[apache] httpd Server not started: (13)Permission denied: make_sock: could not bind to address [::]:88

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.

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.

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

service httpd restart

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

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

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:

1. Install semanage tools: sudo yum -y install policycoreutils-python
2. Allow port 88 for httpd: sudo semanage port -a -t http_port_t -p tcp 88
3. Allow port 8445 for httpd: sudo semanage port -a -t http_port_t -p tcp 8445

I had similar error while trying to start httpd service for openstack train installation in RHEL 7.5 too.

Solution: It got resolved by disabling SElinux.

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.

Start with root user or with sudo, it works fine, here is sample output:

[ec2-user@ip-172-31-12-164 ~]$ service httpd start

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

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

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.
