Kickstart and nvme0n1
by Volker 27 Nov '17

27 Nov '17

Hi all. In recent hardware the first disk has device name nvme0n1 rather then sda How do you tell kickstart to use the first available disk? No matter if it is called sda or nvme0n1? e.g. part /boot --fstype="xfs" --ondisk=sda --size=1000 Regards ....Volker

Creating Spec file for RPM
by Andrew W 25 Nov '17

25 Nov '17

Im trying to learn how to create RPMs but am a little confused by the spec file. Im trying to package up some Python scripts, rather than binary files, and I want them to be installed in a subdirectory under /usr/local which I shall refer to as /usr/local/X Ive put the scripts in a tarball under /home/me/X/RPM/SOURCES but Im getting terribly confused over what to put in the %build %install and %files sections If I set $RPM_BUILD_ROOT to /home/me/X/RPM/temp then put %prep %setup -q that will unpack the tarball, yes?, but where to, /home/me/X/RPM/temp ? how would I then tell it to move the files I want from there into /usr/local/X and set appropriate permissions on them? The examples online all assume you have a makefile with a make install target, could I simply use the cp command under the %install section? But where am I copying from and to? My brain is tied in knots! Many thanks Andrew

Cluster installation CentOS 7.4 network problems
by Vadim Bulst 23 Nov '17

23 Nov '17

Hi there, after using Foreman successful on our clusters for more than a year. I'd like to reinstall a 90 node cluster with Centos 7.4. It's now running on Centos 7.3 . I'm not able to just update to 7.4 because of zfsonlinux dependencies and well - some nodes died and had to bare metal install them. So I was able to install these nodes successfully by pxe-booting and using a regular CentOS mirror with foreman and kickstart. After the final reboot the nodes got no network connection at all and puppet wasn't able to pull of course. After logging in locally and restart NetworkManager the connection came up - sometimes on the first try sometimes on the second try. I never discovered such behavior with Centos 7.3 or 7.2. Network properties: DHCP, MTU 9000 DHCP-Server not Foreman managed, on different network TFTP-Server Foreman managed, on different network I've read one thread on stackexchange which describes a simular problem using a kickstart installation and dhcp network configuration on Centos 7.4 https://unix.stackexchange.com/questions/396096/centos-7-network-service-fa… Does any body of you discovered similar problems? This is what my provisioning template / kickstart template looks like: install url --url http://mirror.centos.org/centos/7.4.1708/os/x86_64 --proxy=http://proxy.uni-leipzig.de:3128 lang en_US.UTF-8 selinux --enforcing keyboard de skipx network --bootproto dhcp --hostname galaxy110.sc.uni-leipzig.de --device=somemacaddress rootpw --iscrypted foo firewall --service=ssh authconfig --useshadow --passalgo=SHA256 --kickstart timezone --utc Europe/Berlin services --disabled gpm,sendmail,cups,pcmcia,isdn,rawdevices,hpoj,bluetooth,openibd,avahi-daemon,avahi-dnsconfd,hidd,hplip,pcscd bootloader --location=mbr --append="nofb quiet splash=quiet" zerombr clearpart --initlabel --all ignoredisk --only-use=sda part biosboot --size 1 --fstype=biosboot --asprimary part / --fstype=xfs --size=20480 --asprimary --ondisk=sda part swap --size=131072 --ondisk=sda part /var/log --fstype=xfs --size=10240 --ondisk=sda part /home --fstype=xfs --size=10240 --grow --ondisk=sda text reboot %packages yum dhclient ntp wget @Core redhat-lsb-core %end %post --nochroot exec < /dev/tty3 > /dev/tty3 #changing to VT 3 so that we can see whats going on.... /usr/bin/chvt 3 ( cp -va /etc/resolv.conf /mnt/sysimage/etc/resolv.conf /usr/bin/chvt 1 ) 2>&1 | tee /mnt/sysimage/root/install.postnochroot.log %end %post logger "Starting anaconda galaxy110.sc.uni-leipzig.de postinstall" exec < /dev/tty3 > /dev/tty3 #changing to VT 3 so that we can see whats going on.... /usr/bin/chvt 3 ( #update local time echo "updating system time" /usr/sbin/ntpdate -sub 139.18.1.2 /usr/sbin/hwclock --systohc # Yum proxy echo 'proxy = http://proxy.uni-leipzig.de:3128' >> /etc/yum.conf rpm -Uvh --httpproxy proxy.uni-leipzig.de --httpport 3128 https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm # update all the base packages from the updates repository if [ -f /usr/bin/dnf ]; then dnf -y update else yum -t -y update fi # SSH keys setup snippet for Remote Execution plugin # # Parameters: # # remote_execution_ssh_keys: public keys to be put in ~/.ssh/authorized_keys # # remote_execution_ssh_user: user for which remote_execution_ssh_keys will be # authorized # # remote_execution_create_user: create user if it not already existing # # remote_execution_effective_user_method: method to switch from ssh user to # effective user # # This template sets up SSH keys in any host so that as long as your public # SSH key is in remote_execution_ssh_keys, you can SSH into a host.

CentOS6 davfs2 shows invalid free/total storage capacity
by Walter H. 22 Nov '17

22 Nov '17

Hello, I have a CentOS6 VM with davfs2 where I mount WebDAV Shares; one I have at a storage hoster and one I configured myself on a virtual server I rented on a hoster; why does 'df' always show the same value for capacity [root@centos6-vm ~]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 11249272 7074512 3596664 67% / tmpfs 393264 0 393264 0% /dev/shm /dev/sda1 218039 79340 127231 39% /boot https://webdav.hidrive.strato.com/ 26666664 13333332 13333332 50% /mnt/hidrive https://myserver.example.com/webdav/ 26666664 13333332 13333332 50% /mnt/webdav the capacity of the hidrive is 5 GB and of mine abount 10 GB ... several time ago I had a hoster, where the correct values where shown, so this seems that this is a server setting, but how/where, I'm just doing this on my server (CentOS with default Apache RPM): DavLockDB /var/lib/dav/DavLock Alias /webdav/ "/var/www/webdav/" <Directory "/var/www/webdav/"> AllowOverride None Options +Indexes Dav On </Directory> <Location "/webdav/"> AuthType Basic AuthName "WebDAV" AuthUserFile /var/www/passwrds Require User walter </Location> are there any settings I can do on server side or can I do something on client side, be shown correct values ... Thanks, Walter

ebtables bug
by Andrew Radygin 22 Nov '17

22 Nov '17

Hi guys! I need to deploy this bugfix - https://bugzilla.redhat.com/show_bug.cgi?id=1495893 on my servers, but I don't want to compile own package. It'll be nice to use official package from centos repo. Could you please tell me, when this fix will be approved and added to main line package ebtables, so I can update it on my systems. Thanks! -- Best regards, Andrew.

File access in Apache 2.4 (clarification)
by david 21 Nov '17

21 Nov '17

Folks I'm having file-access problems in Apache 2.4 under Centos 7. In particular: - I have a file that's readable to every user and every application, (writeable by only one user), but my CGI scripts cannot read it. - Some of my CGI scripts need temporary storage for some files. They are, for example, some internal log files, tnat get cleaned up over time, but I want to be able to look at them (as root). Where would you suggest they be placed? I've tried /tmp/my_private_files/, and /var/tmp/my_private_files/, but Apache fails to find even the directory. Here's some extra information SELINUX is disabled. I modified my CGI script to report where in the path to /tmp/my_private_files/temp_log.log the process failed. The Perl code I ran is: my $x = ""; print STDERR "Trying to read /tmp/ramdisk/keys.txt\n"; for (split /\//, "/tmp/ramdisk/keys.txt") { next unless $_; $x .= "/$_"; print STDERR "Test $x, " , (-e $x?"exists":"does not exist"), "\n"; } And the output in the http error log for this virtual user, (timestamp and other error log data stripped) was: AH01215: Trying to read /tmp/ramdisk/keys.txt AH01215: Test /tmp, exists AH01215: Test /tmp/ramdisk, does not exist AH01215: Test /tmp/ramdisk/keys.txt, does not exist Using the "dir -l" command as root, I discover: dir -l / | grep tmp drwxrwxrwt. 16 root root 4096 Nov 21 08:35 tmp dir -l /tmp | grep ramdisk drwxrwxrwt 2 root root 140 Nov 21 08:35 ramdisk dir -l /tmp/ramdisk | grep keys.txt -rw-r--r-- 1 user1 user1 11829 Nov 21 08:29 keys.txt Any suggestions? PS: Centos 6 had no such problems, and the file locations worked just fine. David
