httpd: could not bind to port 80 - how not to stop a process

Learning the hard way

Here's what I was doing (don't do this): killall httpd. After a few
times cycling httpd up and down, I found that httpd would not start at it. Here's
the error message I was getting:bind: Address already in use httpd: could not bind to port 80. I was confused. I checked to see if httpd was already running by doing: ps -auwd | grep httpd But nothing was found. So my next query was: netstat -a | grep http tcp 0 0 xxx-xxx-xxx-xxx.ip.http jagged.net.1224 ESTABLISHED tcp 0 0 xxx-xxx-xxx-xxx.ip.http nt1.3917 CLOSE_WAIT tcp 0 0 xxx-xxx-xxx-xxx.ip.http nt1.3916 CLOSE_WAIT where xxx-xxx-xxx-xxx was the IP of my web server. Nobody seemed to know what was going on. Eventually, I rang Jay. We talked for about 10 minutes and eventually decided that I had some zombie processes left over. This was a result of the killall I had been doing. So I had to reboot. Unfortunately, I was at the following uptime: 3:39PM up 50 days,17:42, 4 users, load averages: 3.00, 3.00, 2.92 This had been a record for me. Let's see how the next one goes. |
