I'm attempting to create a simple CGI script using CentOS 7, Apache 2.4 and Ruby 2.0. All tools installed from official packages.
My script, which resides at /var/www/cgi-bin/test.cgi is:
#!/usr/bin/ruby
puts "Content-Type: text/plain\n\n"
begin
file = File.open("test.log", "a")
file.puts("foobar")
file.close
rescue Exception
puts "pwd: #{`pwd`}"
puts $!.inspect
end
When I load http://myhost/cgi-bin/test.cgi, I get the following:
pwd: /var/www/cgi-bin
#<Errno::EACCES: Permission denied - test.log>
However:
[root#host cgi-bin]# ls -l /var/www/cgi-bin
total 8
-rwxr-xr-x. 1 root root 153 Jul 10 22:03 env.cgi
-rwxr-xr-x. 1 root root 359 Jul 11 00:45 test.cgi
-rw-rw-rw-. 1 root root 0 Jul 11 00:42 test.log
How (and where) can I write data from inside this cgi script if not to a world-writable file in the script's own working directory?
SELinux was blocking the file writes. "setenforce Permissive" allowed them to go through. Edited /etc/sysconfig/selinux and rebooted to make permanent.
I am trying to configure Magento to use memcache for session. I have installed memcached and also php5-memcache. I have also added "extension=memcache.so" in memcache.ini.
I have made sure the memcached instance is also running in the localhost port number 11213. However, when I try to login to Magento admin I get an error -
Warning: Unknown: Failed to write session data (memcache). Please verify that the current setting of session.save_path is correct (tcp://127.0.0.1:11213?persistent=0&weight=2&timeout=10&retry_interval=10) in Unknown on line 0
The following is the memcache configuration in local.xml -
<session_save><![CDATA[memcache]]></session_save>
<session_save_path><![CDATA[tcp://127.0.0.1:11213?persistent=0&weight=2&timeout=10&retry_interval=10]]></session_save_path>
The following are the grep for memcached,
www-data 1329 1 0 08:13 ? 00:00:00 /usr/bin/memcached -d -m 64 -p 11213 -u www-data -l 127.0.0.1
www-data 1511 1 0 08:18 ? 00:00:00 /usr/bin/memcached -d -m 64 -p 11211 -u www-data -l 127.0.0.1
www-data 1518 1 0 08:18 ? 00:00:00 /usr/bin/memcached -d -m 64 -p 11212 -u www-data -l 127.0.0.1
I have been meddling up with this for a couple of days now and I am not sure what the issue. Any help is appreciated.
Thanks,
G
Please note there is a difference between memcache and memcached. I’ve found that the Magento sessions integration expects you to use this:
<session_save><![CDATA[memcached]]></session_save>
You should install the PHP memcached libraries, as well.
I'm currently looking into options for process monitoring of Rails/Ruby Projects and quite like god.
But i cant really find anything on how to monitor multiple applications (for example 2 rails projects running on one machine) with god.
As far as i see it i just set up god (system ruby) and have each project add its own configuration (maybe somehow in a deploy-hook).
This should also work with the projects running different ruby versions (rbenv, rvm) or bundler, since the god ruby does not have to access any project code.
Does anyone already use it like this? Or is there a better approach?
I use god to watch all my stuff (unicorn, redis, resque workers). Basic setup is like this:
God is installed globally, loads on system startup and reads its config file, /etc/god/all.god.
/etc/god/all.god
files = Dir.glob "/etc/god/**/*.god"
files.each do |f|
next if f == '/etc/god/all.god'
God.load f
end
This file loads all config files in /etc/god and its children. Deploy scripts put config files there and tell god to (re)load them.
$ ls -l /etc/god

lrwxrwxrwx 1 sergio sergio 57 2012-03-20 20:59 unicorn.god -> /srv/app1_production/current/config/god/unicorn.god
Here's a head of unicorn.god.
rails_env = "production"
pid_dir = "/srv/app1_#{rails_env}/shared/pids"
rails_root = "/srv/app1_#{rails_env}/current"
God.watch do |w|
w.name = "unicorn-#{rails_env}"
w.interval = 30.seconds # default
# unicorn needs to be run from the rails root
w.start = "cd #{rails_root} && /home/sergio/.rvm/bin/r193_bundle exec unicorn_rails -c #{rails_root}/config/unicorn/unicorn.#{rails_env}.rb -E #{rails_env} -D"
# QUIT gracefully shuts down workers
w.stop = "kill -QUIT `cat #{pid_dir}/unicorn.pid`"
# USR2 causes the master to re-create itself and spawn a new worker pool
w.restart = "kill -USR2 `cat #{pid_dir}/unicorn.pid`"
As you can see, unicorns are launched via rvm wrappers and therefore each new app can use its own ruby. Also, you provide your own start, stop and restart commands, so you can use god to watch any piece of software.
This approach works very well for me (so far).
Jekyll was working fine for me few weeks back but now all of a sudden it gives me the following error:
TCPServer Error: Address already in use - bind(2)
INFO WEBrick::HTTPServer#start: pid=7300 port=4000
% lsof -i :4000
<fetches nothing>
Even though nothing is running on the port. Below are the details:
% jekyll --version

Here is the output
% jekyll --server

I know the address isn't in use and jekyll is probably breaking for some other reason but throwing that error. What are my options? I've tried re-installing as well.
Type this in your terminal to find out the PID of the process that's using the 3000 port:
$ lsof -wni tcp:3000
Then, use the number in the PID column to kill the process:
$ kill -9 PID
I was not qualified to post comment. So I added a new answer.
I encountered this problem on Mac OS X 10.10.3. And I had never installed/used Jekyll before. I was not able to start jekyll server with its default port number 4000. The reason was that the port was the same as what NoMachine used. With
$ sudo lsof -wni tcp:4000
Note: Running this command without sudo will have no output.
I saw this output:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nxd 449 nx 3u IPv4 0x8d22************ 0t0 TCP *:terabase (LISTEN)
nxd 449 nx 4u IPv6 0x8d22************ 0t0 TCP *:terabase (LISTEN)
The port 4000 was occupied by nxd, which was the process started by NoMachine. And
$ sudo kill -9 449
would not work, because NoMachine's nxd process would keep restarting, with a new PID.
Therefore, I had to either:
Changed my jekyll server port in the site _config.yml to another spared one. I appended the line below to _config.yml and it worked.
port: 3000 # change server port to 3000
or
Changed NoMachine's default nxd port, or Uninstall NoMachine
Ctrl-Z doesn't terminate a program, but rather suspends it and sends it to the background. You can resume the program with the "fg" command. To actually terminate it, use Ctrl-C.
The actual error message seems to be bogus and can be ignored. I am getting the same error message "address in use" but jekyll works fine anyway at the expected port.
I have met this problem recently.
I tried out all the method mentioned above, and even restarted my computer, but still couldn't solve it!!! Then I removed the jekyll and installed a new version, it just worked.
gem uninstall jekyll & gem install jekyll (maybe you need super user priviledge).
If you really get annoyed with similar bugs, this sb method is worth a try...
Based on the top answer, I came up with a simple way
lsof -wni tcp:3000 | xargs -I{} kill -9 {}
It takes the output of finding PID in which port the tcp server is running at. In this case it is 3000.
It then kills the processes running that
PID
Check that you don't have another terminal open where you are already running a server.
If that is the case, do a CTRL-C to shutdown the server, and that will free the port/address.
First you need to find PID of the process that's using the 3000 port:
$ps -ef

Any clue ?
Are you sure you edited the right file? OS X Server has a way of not keeping to standards. The actual configuration entries are not in /etc/httpd/httpd.conf, but in subdirectories of /etc/apache2/sites. Check out this FAQ.
I would recommend using the Server Admin utility to set up the server. It will be a lot easier and quicker than trying to get the configuration right manually. You can always add or change rules later, once the site is up and running.
No direct local GUI access possible for a few days, no access via Remote Desktop either. My only way is ssh right now, but I will be happy to try Server Admin utility in a few days. For now I am restricted to the command line. Yes, I edited both /etc/apache2/httpd.conf and /etc/apache2/sites/0000_any_80_.conf, without avail. Is
