[Tutorial] Fix not boot Apache

Thứ Hai, 26 tháng 5, 2014

This is a post sysadmins out there For those who tremble into problems with servers running a LAMP setup.

Occasionally, for some reason or another - usually Because you changed some settings - it is Necessary to restart apache from the terminal (ie in putty).

Sometimes, though this is rare, this fails. If apache fails to restart and displays a message similar to "Address already in use: make_sock: could not bind to address" then unfortunately you wondering how to Get Your friend server back online!

The precise message you receive could look something like this:

Starting httpd: (98) Address already in use: make_sock: could not bind to address [::]: 80

(98) Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

You may not have sewing or other error messages, but let's deal with this one!

The slow fix is to do a full reboot của server hardware. This takes quite some time, and is not necessarily the best course of action, but it nên solve this issue.

The reason for the message, tuy nhiên, là có there are still active connections were not closed before. Probably some process was running When you hit "restart" (Identify Nên just by checking what - but that's beyond the scope of what we're doing here!). In any case, you'll want to find out what process is running, and "kill" it.

Here's how:

1) Type:

ps-aux | grep httpd

2) This will return a set of processes running đó are thời. There nên vài friend or two. It will look something like this:

root 23605 0.1 0.1 861052 21208? Ss 10:07 0:00 / usr / sbin / httpd
apache 23609 0.0 0.0 220500 7720? S 10:07 0:00 / usr / sbin / httpd
root 23697 0.0 0.0 61184 776 pts / 0 S + 10:10 0:00 grep httpd

3) Kill the apache processes are showing đó by typing:

kill -9 23 609

Remember to replace "23 609" with whatever number your process actually is!

An alternative to this, if you have a lot of all running processes, is to use the "killall" method, mà:

killall -9 httpd

Then restart apache - it nên đúng work!

service httpd restart

You'll then want to set about đó Identifying processes were causing this in the first place!
