Server :: Memory - GNOME Or KDE Installed On Their Server
Jul 3, 2010
Wondering if most people have GNOME or KDE installed on their server, and how much memory do these guys consumed.
I have been running a VPS website with only 256MB of RAM fine, though memory does appear to be a bottleneck at times. So got a new server with 1GB RAM but I'm surprised to see after installing CentOS 64-bit with GNOME the memory consumption varies between 600MB-1GB.
The only difference is I've never had used any GUI desktop on the VPS (don't think the hosting company offers one). Wondering if the memory consumption came entirely from the GNOME desktop I installed.
Would most people install with GNOME, configure all the stuff required, and then remove it?
I want to sync files from my home directory on my linux server to my local computer. I noticed the instructions for [URL] only has instructions for linux with gnome/kde. can i use dropbox without a gui?
Last weekend i've set up my first headless ubuntu home file server and torrent downloader with ubuntu 9.10.Very cool but CPU is way too fast for a home server: P4 HT 2.8Ghz, unfortunatly it has only 256Mb of ram, so no X server and no VNC (old HP office pc) At the moment memory usage is only 40Mb without X server. Besides SSH works just fine Few questions i can't seem to find answers to on google:What is a good CL network monitoring program?mething similar to htopUbuntu 9.10 has a lot, about 20-30, console-kit deamon instanses running after boot each using some memory that i can't spare.
Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.
I installed IBSng in ubuntu-server .but i can not start this server :Code:[root@myserver]# /etc/init.d/IBSng start.: 8: Can't open /etc/rc.d/init.d/functions"functions" file is in RPM base system . and ubuntu have not this file
I'm looking for a way to put a MySQL database in a server's memory. The disks aren't fast enough to keep up with the usage and I don't feel like going for a splitted web&db server yet because of the costs.
Because this involves risks (unless there's a way to read from the memory and write to the memory AND disks?), so I'd prefer that the DB gets copied automatically every hour or so to the local disks.
I have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.
One of my server is going down and it gives the messages (screenshot attached). This has happened twice and the server is running stable for the time being.
I wanted to know if we can determine what caused the Memory overusage. Is there some log files to check ?
Also is there some script that runs say every minute and determines which software is using maximum resources so that when the server crashes we know what caused it.
I have installed nfs-kernel-server on the server and nfs-common on the client. Assumeserver 192.168.1.1client 192.168.1.3
content of /etc/exports is: /home 192.168.1.0/255.255.255.0(rw,sync,no_root_squash) /home/nfsroot 192.168.1.0/255.255.255.0(rw,no_subtree_check,async,no_root_squash)
I have a RHEL5 machine having mysql5.0.22 is installed in it. i also installed java through "jdk-1_5_0_19-linux-i586.bin" package, and its version is 1.5.0_19. I am trying to check if any JDBC driver for Mysql Server is installed on my system . How can I do this? If any driver is already installed How can I get the file path for those driver files? is it comes along with jdk packages? As i am not a programmer, and does't know more about jdbc.
I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.
My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.
I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.
I have a query regarding top & virtual memory. When we run top it show VIRT (Virtual Mem), RES (Resident Mem) & SHR (Shared Memory). The total virtual memory of my machine is 4 GBs (2 GB RAM + 2 GB Swap), but still I am able to see a process showing 4000m virtual memory column. what it means, as its show VIRT Mem more than actual available VIRT memory
I have developed a small website using jspx pages.Now i want to host the website to a server which is a linux machine.The linux machine which i m referring to is already hosting some web pages(jspx) through a web server Which is running at port 8888.My first question would be "How would i check which web server is installed in the server?"Due to my little knowledge about linux machine .I have copied some simple html pages to /var/ www/ html location. The pages are getting accessed correctly on port number 80.But how would i go about hosting jspx pages.
On my local apache web server I had installed gnome desktop, because I wanted it to use as a TV. But when I installed the gnome desktop, my requests for web pages became terribly slow (4-5 seconds!). When I deinstalled the gnome desktop, the request where fast again. But I still want to watch TV on my server, so I wander if people know why the gnome desktop harms the performance of the server?
PS. with gnome desktop, ping was <1 ms, samba server worked like charm, wget localhost was <1 ms, but for some reason, when tried to get a webpage from my webserver to a remote machine, it took seriously 4-5 seconds to load a page.
I install Ubuntu Server Lucid , Lamp 5200+ DualCore , 2GBmem etc . + Install Gnome Interface not all only strict necessary! On top kill almost process! It use 90% memory On Desktop Edition works fine all on Server normally whiteout X11 must be work fastest - here is lower !(I install few times is not bad installation)
I have xen kernel on a 5.4_64 though it seems to have always done this regardless of version. When I add a virt the control set shows the total machine memory minus what I just allocated to the new virt. This also shows up in the system monitor as total available ram. Problem arises in deleting and making new virts. The memory never reappears as usable after deleting virts. So now after testing several different setups I'm down to 1.4 gigs showing available on the dom0. What can I do to recover this lost memory? I've searched, read, looked every where I could think of and there just doesn't seem to be any information about deleting virts only adding them.
I have a web server with the specs below and my apache server is being a hog using all my RAM 7gigs or 8gigs of ram. When there is a rush of traffic at once my whole server crashes and I have to reboot apache. The way my site is set up I have a tube script and I use the tube script to host videos on my forum I have 1000 videos on the tube script. I brought a bigger server and more ram because of the down time I been having . I am really trying to figure out why its crashing and using so much ram. I installed eAccelerator didn't seem to help with the apache server.

I got a legacy server, and through munin I notice that periodically commited memory keep on increasing. The chart looks like a spiky sine graph, but every cycle it increase both max and minimum. After few days it will go over my physical memory it will keep on growing until the machine crash... Usually I reset the memory by rebooting the machine which is not a solution at all. Is there any way to know what process(es) that took the committed memory? Is there any way to release the committed memory without rebooting the machine? Is there any way to cure my machine from this disease? as an information, I'm using CENTOS 5.5 i686, AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ this is what I get from /proc/meminfo

I am trying to troubleshoot an Apache/Mysql server that once every few days falls over due to memory starvation. I thought I had tuned my httpd.conf file with relativley small MaxClients and so on, but then noticed some unusual RES values in top while monitoring.
In short, `top -b -n1 -u apache` shows that I have 28 httpd processes. their VIRT is ~300MB for each process (I understand this is shared), and the RES ~50MB for each. I thought this wasn't shared. Is this true? I just noticed 2 of the processes jump to 1.2g. If RES represents non-shared memory then concievably 1.2g x 28 processes would be a problem on an 8GB server.
If I have a centos linux server, how can I stop a user on the server from eating all the memory and swap space memory, maybe due to a poorly written script, infinite loop etc?
I am still confused about the memory issues. i have allocated JAVA_OPTS='-Djava.awt.headless=true -Xms512M -Xmx512M -XX:MaxPermSize=512M' think that it means that i have allocate java to use only 512mb of my memory. but when i run top here is my output.

I have an issue with few servers. All have OEL 5.5 and various versions of oracle (mainly 10g something).
I've noticed on one machine that amount of free memory is slowly decreasing. When it comes to less then 30M, application has problems. Ive tried adding mem on this machine (virtual), and it behaves the same.
The same is on physical machines I have simmilar, if not the same config. Variations are with physical memory installed, and it does not matter if servers have 2G, or 8G, free -m gives around 30 free
It does not swap, and does not make some big issues on other machines, but on this one, application that uses this DB timeouts the user. Is there some chance to check what is creating this issue?
P.S. I've tried with DB admin to check something related to oracle itself, bit when we shutdown instance, Oracle frees 1.5G allocated to him, but nothing else. Will try testimg a bit more, but any thought on this is usefull. This is production server, so no big issues can be done. Will try to copy it to other hardware and do some testing, but then no App server available to attack it.
I have many documents that indicate many different min requirements for drive memory. Will someone give me an idea for the following...Ubuntu 10.10 server running SSH and Samba what would be the memory requirements, recommended as opposed to min, for partitions as follows: / -- root /home -- as a separate partition /boot -- as a separate partition (do I really need a separate boot) swap my RAM is 768mg so 1 gig should be good
