OT:: Multiple PHP versions
by TE Dukes 22 Aug '22

22 Aug '22

Hello, Been trying to get multiple versions of PHP on a CentOS 7 machine, off and on for the past couple months. I have followed 5 or 6 different howtos but none work. They are very similar and they seems to be done on a fresh install as most do an apache install is the steps. I setup two virtualhosts one for PHP5.6 and one for PHP 7.4. When I create a file with phpinfo, it reports back 5.6.xxx on both sites. So, I'm wondering if I need to remove the existing PHP version that is included with CentOS? Any suggestions or a better way to do this? TIA

Qemu - enabling "bridge mode" for primary physical interface for VMs
by Lists 19 Jan '22

19 Jan '22

I have a physical host with a single physical network adapter. I want to host several VMs on host. (guest1 - guest4) The guest systems are accessible via 192.168.122.* as is the default with qemu/virsh. There are 4 IP addresses being routed to the primary interface on host. I can set up an alias for the NIC and "see" these ip addresses. I understand that it's possible to allow the 4 VM guest systems to each have a "direct" fixed IP address and access the addresses \via the host network adapter, while the host retains its fixed IP. I've been googling like crazy and there is a lot of stale and conflicting information. Has anybody here done this successfully? Host and all guests are running CentOS 8. Thanks. Ben S

NFS Share fails to mount at boot time
by Felix Natter 15 Jan '22

15 Jan '22

hello fellow CentOS Users, on Scientific Linux 7 (_very_ similar to CentOS7), I get this when trying to mount NFS Shares (exported from Synology NAS) automatically at boot time: [root@HOST ~]# journalctl -b 0 | grep NAS[20] Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS0... Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS2... Jul 01 13:32:09 HOST systemd[1]: mnt-NAS0.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS0. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS0.mount entered failed state. Jul 01 13:32:09 HOST systemd[1]: mnt-NAS2.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS2. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS2.mount entered failed state. I read that enabling NetworkManager-wait-online.service can mitigate that, but it's already enabled: [root@HOST ~]# systemctl list-unit-files|grep wait chrony-wait.service disabled NetworkManager-wait-online.service enabled plymouth-quit-wait.service disabled /mnt/NAS2 is defined in /etc/fstab (/mnt/NAS0 is mounted analogously): NAS2HOST:/volume1/export/ /mnt/NAS2 nfs rw,vers=3,soft,bg,intr 0 0 This does not always occur, and it seems to be a race condition, because it did not occur a few months ago, before we moved offices (when only the networking changed slightly). Of course, once the computer is booted, I can always mount the shares without problems. Does someone have an idea? Many Thanks and Best Regards, -- Felix Natter

how to clear out /var/cache?
by Fred 04 Jan '22

04 Jan '22

Is it safe to just remove files from /var/cache on a running system, or is there a correct procedure for doing that? Mine has hit over 3 gigs, making it one of the larger directories in /, which is running low on space. I've hit all the low-hanging fruit I can find and now I come to things like /var/cache, and I don't know what to do about such. Thanks in advance! Fred

Re: [CentOS] how to clear out /var/cache?

Skylar: that's more or less what I've been doing, looking for huge things in /. Kenneth: the latest version of kdirstat appears to now be named qdirstat, no kde bits required. it is certainly a handy way to quickly find the disk space sinks. Thanks for the pointer. but I still don't know the proper way to clear out a lot of this stuff. I certainly don't want to hose my system. It is C7, up to date, and it has been running for at least five years with partitions as they are set now: / is 50 gigs. had a popup message this morning telling me that / was nearly full. found it with 2 gigs free. sounds as if something has been slowly eating away at the space. I could use gparted to rearrange things, making / bigger, but as it has been going for five years, it strikes me that it more likely needs a lot of garbage collection to be done. I've manually cleaned up some detritus, it now reports 3.7G free which should hold me for a little while. So, can anyone advise me on what is and what is not safe to whack/delete from the root partition? Thanks!

Delete local user/group but not LDAP one
by Felix Natter 30 Dec '21

30 Dec '21

Dear fellow linux users, I have a computer with a local user X that shadows an LDAP user of the same name (and group). I know I can use: userdel X groupdel X but how do I make sure that the LDAP is not changed, and only the local user/group is deleted? This is very critical. Many Thanks and Best Regards, -- Felix Natter

issue with virt-install and CS9 boot iso
by Leon Fauster 29 Dec '21

29 Dec '21

I wanted quickly spin up a CS9 system with an virt-install command line that in the past worked with fedora34 and C8 but I am getting following error: ERROR Error validating install location: Could not find an installable distribution at URL '{trimmed path}CentOS-Stream-9-20211222.0-x86_64-boot.iso' Some search engines found some sites that are giving examples to pass locations of kernel and initrd. Are the iso files "wrongly" created or are such parameters required now? Host: CS8 virt-install -n c9x86-parttest -r 3072 --disk path=parttest.img,size=18,format=qcow2 -l CentOS-Stream-9-20211222.0-x86_64-boot.iso --os-variant rhel9.0 --noautoconsole -x "inst.ks=https://example/parttest.cfg" -- Leon

Roundcubemail
by TE Dukes 28 Dec '21

28 Dec '21

Hello, Just upgraded from CentOS 7 to CentOS 8 Stream and there is no rpm for roundcubemail. Could I get the SRPM for CentOS 7 and re-do it for CentOS 8? I really hate installing a non-RPM package. If not a good idea, what is available for webmail in CentOS 8 Stream? TIA
