[CentOS-docs] Installing Java on Centos
Hello, I have recently tried installing Java on Centos 6.4 and have found that the wiki tutorial for this subject is quite outdated (the proposed method doesn't work on the new version as the spec file is outdated and there is no need to rebuild the rpm with nosrc file anymore). I would like to post a tutorial on installing Java on Centos that would be more up-to-date and referring to the newer available versions of both Centos and Java. Regards, Olga ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

[CentOS-virt] KVM virtual machine and SAN storage with FC
Hi Team, Thanks for the good explanation. If that is not workable for the database, can anyone recommend me for the setup of the database clients and data files in order to achieve HA and load balancing? How should I set up my VMs and stations (Two machines with two VMs each)? I will appreciate for a workable approach and that is practical for the HA/Load balancing.

Re: [CentOS] odd inconsistency with nfs
If anyone has ideas and/or needs more info, please let me know. Step 1 in debugging and troubleshooting... Use the KISS principle. Right now in that you have NIS, NFS, CentOS server and Solaris client (version? Given the red hat 7.3 instance you had would a safe assumption be not 11 or even 10?) Cut this down to work out which cog in the wheel is broken as there are just too many variables... Can you mount the NFS share locally to another directory on the NFS server? If that works can you mount it with a CentOS 6.4 client on another system? It's been a while since I had to deal with NFS but I see you have symlinks in exports... I thought at least under 3 that was definitely not supported and you should use bind mounts... http://mail-index.netbsd.org/tech-kern/1995/05/28/.html Start there and see how you go... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] odd inconsistency with nfs
- Original Message - | I'm having an interesting/odd problem with nfs (I think).

[CentOS] This isn't supposed to be difficult (how to nntp post to the Gmane Pan user group)
I realize this is (mostly) off topic, but I'm befuddled as to *how* one can post to the Gmane Pan Users' group (gmane.comp.gnome.apps.pan.user) using any nntp USENET client (e.g., Pan, on Centos). I'm already subscribed (by having sent an email to pan-us...@nongnu.org); but I just want that USENET group to work like *this* USENET group, where I can post using a server:port login:password combination such as we use here: Server: news.gmane.org Port: 119 Login: blank Password: blank User: Rock I've looked here (http://dir.gmane.org/gmane.comp.gnome.apps.pan.user) and if the answer is there, I don't see it (maybe I missed it?).

[CentOS] Server dies after kernel upgrade
I am running a server with CentOS release 6.4 (Final) and the kernel version of 2.6.32-279.19.1.el6.x86_64 and everything looks ok, but when I do a yum update on the kernel to update it to a newer version 2.6.32-358.11.1.el6. It will not restart after the required reboot. It will start to load until the task bar at the bottom gets to the end than it stops loading I have been patient with it unless it requires more time to start but after 10min it was still just sitting at the task bar. This is a VM machine so I just revert to a previous snapshot, but what should I be looking for that would cause this, and how should I fix it?

Thanks, Chris ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos I recall this happening to me in the past. Hit esc when the loading bar starts to run across the screen and see what it stops on. Go into single user mode and see if you can look at the logs. Can you select the older kernel when the grub pops up? You may have to use chkconfig to disable services from starting after you see whats in the way. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] sda and sdb reverse order with an external USB drive
Hello I am using 64 bit CentOS 6.4 on an i7 laptop with one sata drive and a CD drive. I installed CentOS by manually partitioning sda as: sda1 as /boot, sda2 as swap, sda3 as /. The booted system works great. When I insert an external USB drive, formatted as ext3, the hard drive on the laptop and the USB drive are either sda or sdb, depending upon the order on which I insert the USB drive and boot the system. Please see the two mount commands below for each of these situations. This seems to work in either order except for the fact that I don't want my USB drive to automount. What I want is that after I insert the USB drive in a running system and wait 15 seconds, I want to mount the USB drive with the command # mount /mnt. To accomplish this I added a line to /etc/fstab but it didn't work. When I uncomment the last line in fstab (see below) the computer hangs and doesn't boot. I was successful with this strategy on a similar laptop with Fedora 18 but not my current one. Thank you, Joe Hesse The following mount command was issued by first completely booting CentOS and then inserting the external USB Drive. Note the sda3 is / and sda1 is /boot. [root@XoticPC ~]# mount /dev/sda3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sdb1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) The following mount command was issued by inserting the external USB drive in a powered down computer and then booting. Note the sdb3 is / and sdb1 is /boot. [root@XoticPC ~]# mount /dev/sdb3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sdb1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sda1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) The /etc/fstab file was generated by the install process. The commented line at the bottom was added by me in an unsuccessful attempt to be able to insert the USB drive in a booted computer, not having it mount, and then control the mounting with # mount /mnt. The last UUID is the UUID of sdb1 determined with the command # blkid /dev/sdb1. # /etc/fstab UUID=1d7606b7-46b8-4b29-9a4e-a50a1f6a1759 / ext4defaults1 1 UUID=e0fdfeb1-e7a7-4a06-b5fa-7730c3c2e60d /boot ext4defaults1 2 UUID=d0e3c2ee-7c66-4d13-b387-1da958020b1a swap swapdefaults0 0 tmpfs /dev/shmtmpfs defaults0 0 devpts /dev/ptsdevpts gid=5,mode=620 0 0 sysfs /syssysfs defaults0 0 proc/proc proc defaults0 0 #UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As Lubomir pointed out yesterday, the latest kernel is vulnerable to a DoS attack, so you should probably use a different one. See Johnny's message for details, and an untested kernel that you could use instead: http://lists.centos.org/pipermail/centos/2013-July/135671.html It will not restart after the required reboot.

You can either try ctrl-d or ESC during the splash screen process (I don't remember exactly which one), or you can edit the grub command line when it runs on boot and remove the rhgb and quiet options from the kernel options. --keith -- kkel...@wombat.san-francisco.ca.us ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The take-away is that you cannot depend on device names being stable, it depends on the order in which devices are enumerated at boot time. In my case, an eSATA drive shows up as the first device if it is turned on when the system boots. It apparently enumerates as sda and the rest of the drives are bumped up one drive letter. The system boots OK, but the drive letters are different. When I want to mount the external drive I use LABEL=. When I formatted the external drive I specified a filesystem label and rather than specifying /dev/sdb1 in my fstab I used LABEL=fslabel. That way it doesn't matter what device name comes up, it mounts the filesystem by that label. The label can be added after-the-fact using tune2fs or the appropriate tool for the on-disk format. You can also use UUID=uuid if you prefer to use UUIDs. See the mount manpage for more information. Of course, I could be wrong about what you are trying to accomplish, but I think it might be applicable.

Re: [CentOS] This isn't supposed to be difficult (how to nntp post to the Gmane Pan user group)

I did ask Lars but he controls gmane, not the pan users group. Amazingly, the pan users group just (apparently) assumes you omnipotently already know what to set the NNTP client server:port, login:password, and user:email to in order to post successfully. For example, this is what you need to post to *this* group: Group name = gmane.linux.centos.general Server = news.gmane.org Port = 119 Login = blank Password = blank Username = Foo Email = f...@bar.com == this is all that needs to be pre-registered in order to post to gmane.linux.centos.general. (I forget how I had pre-registered, but, IIRC, I had sent an email to someone at somewhere and they wrote back with the instructions above - which allows me to post as long as I put that email address in the posting profile). ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It is (fully) off topic That said, if you post the first time to a mailing list per gmane then gmane will send you a mail that you must answer. You post per nntp the first time gmane sends you a email per smtp you reply to that email you wait some time ... something like that, but as said, when you have problems with gmane, ask gmane. -- Markus ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Server dies after kernel upgrade

As Lubomir pointed out yesterday, the latest kernel is vulnerable to a DoS attack, so you should probably use a different one. See Johnny's message for details, and an untested kernel that you could use instead: http://lists.centos.org/pipermail/centos/2013-July/135671.html It will not restart after the required reboot. It will start to load until the task bar at the bottom gets to the end than it stops loading I have been patient with it unless it requires more time to start but after 10min it was still just sitting at the task bar. You can either try ctrl-d or ESC during the splash screen process (I don't remember exactly which one), or you can edit the grub command line when it runs on boot and remove the rhgb and quiet options from the kernel options. --keith There are always 3 kernels available for boot. Only one gets updated. So first check if other two you have are booting properly. Then you can list all available kernels with yum list kernel --showduplicate and select one and install it like yum install kernel-2.6.32-358.6.2.el6.centos.plus and see if this one works. If it does, you can use it. A thing to check is if you need to recompile VM drivers for new kernels. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
