    Good day Everyone,

    I recently picked up a dedicated server from hetzner based on a recommendation from a reputable member here.

    I don't think I'm having much luck with it for the following reasons:

    1. It was a nightmare to get lvm working, as I wanted to combine both the 2TB drives into 1 and you can seem to only do that if you set it as SWRAID 0, but they don't tell you that, so I just had to keep experimenting.

    2. Once I got centos 7.3 minimal installed, I updated it and tried to install centminmod 123.09beta01, but it kept failing at the part where it tries to download wget (sorry I don't have any logs to share right now, I've been dealing with this for a few days).
    Upon coming to the conclusion that there is some sort of network connectivity issue, I confirmed this by git copying a random project between this new server and my old one and the new one of course fails. I then took all the bs hetzner values out of the /etc/resolve.conf, and I tried a few different ones before I settled with google's, I even at one point tried stealing the content of my other ovh server resolve.conf and using the same nameservers, that didn't work at all.

    3. Eventually I was able to hack-job a centminmod install and manually intervening as things were failing and trying to get them to work, however, the result was a centminmod that looks like it functions but was missing Memcached, "php is not installedproperlyy", phpfpm, dont know, it probably doesnt work either. I think the only thing that installed and worked was mysql.

    So I put in a ticket but then realized a few min later than the response to this ticket may be the same as other 1 line ticket responses, me...long email explaining my partition issue, response: "Have you tried using raid", well more info never killed anyone,

    So i decided to cancel the server and immediately and put in an order for a new one, but if i need to play dns games and make tweaks to have this thing get up and running even before I dive into centminmod again then I'll be cancelling permanently and going elsewhere, ovh is good and i may have to go back there again. I canceled my vultr server as i wanted to set up a personal vpn server but realised it would cost too much if im piping close to 200GB through the server everymonth.

    Any recommendations from existing hetzner users. I'm not a big fan of turning my back on a company especially If I was in the wrong and/or didn't follow their proper procedures.

    @inthecloudblog i believe uses hertzner ? Haven't myself so can't really help without the install logs from your failed install attempt.

    You'll need to post on the forums with the following info
    • Server or VPS details ? XEN, KVM, OpenVZ, VMWare or dedicated server ? OS ? CentOS 6.7 or 7.2 ? 32bit or 64bit ?
    • What version of Centmin Mod ? .07 stable or 08 stable or .09 beta01 or another branch version ?
    • Was it fresh install or upgrade ?
    • Method of install ? Via centmin.sh menu option 1, Git install or curl one liner install as outlined at centminmod.com/download.html ?
    • How long ago did you install Centmin Mod ?
    • There's numerous code changes, bug fixes over time, so ensure you have latest Centmin Mod code installed by upgrading your Centmin Mod code as instructed below.

    Troubleshooting Initial Install



    To troubleshoot initial installation, you need to check the initial install log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the initial install log. You can see full details at How to troubleshoot Centmin Mod initial install issues

    Example list /root/centminlogs files in date ascending order and grep for install.log
    Code (Text):
    ls -lahrt /root/centminlogs | grep install.log
    

    example output returns install log at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log
    Code (Text):
    ls -lahrt /root/centminlogs | grep install.log
    -rw-r--r--  1 root root 2.2M Oct 11 01:40 centminmod_1.2.3-eva2000.09.001_111016-112321_install.log
    

    in SSH use cat to ouput contents of /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log. Clear your SSH client window/buffer so only output is the contents of the file
    Code (Text):
    cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log
    

    Then copy and paste into Pastebin.com or Gists entry. If your SSH window scroll buffer isn't that large to get the whole contents of the install log, you can download file manually and copy and paste contents. But makes sure it's sanitised version of the contents of the initial install log as outlined at How to troubleshoot Centmin Mod initial install issues

    Thanks @eva2000, I didn't post any logs and didn't keep them as I've never seen a server behave this way, it's almost as if the server was going through cycles of offline existence, and I'm fairly sure there's some sort of hardware issue there. I've canceled and got a new server and using centminmod git install method and everything seems to be going smoothly so far.

    Yes, as I thought. I received an email where they said that they're going to take a look at the old server as they suspect an issue, and centminmod installed perfectly on the new one

    wow, so accidentally closed the ssh tab while things were installing, so to be safe, reimaged, reinstalled everything, centminmod using curl this time:

    That's correct.

    There is a rescue mode that should help you

    You can also make use of LARA if needed. It's free for some time.

    great to hear :)

    If I was you, I'd still be curious as to what was wrong with previous server too. If there's not consistent reliability, it could be a problem with your server further down the road - depending of the cause of the problem

    And I was @eva2000, but my options at that time was to wait and see how they'll fix it and probably a constant back and forth of emails before they actually decide to do something so I figured there's no point. It looks like it was some hardware issue so hopefully the new server wont have the same fate.

    Wow I think hetzner may not work for me. Everything is good to go, installed 1 site, installed netdata, upgraded to php 7 and installed GA for ssh. Now when I attempt to run centmin i get this:

    Code:
    [04:45][root@cluster1.xxx.com /]# centmin
    /usr/local/src/centminmod /
    and it just sits there, nothing happens, any ideas before I reimage and start again, although if I have to keep doing that then you may be right @eva2000 this company may be nothing but problems. I wanted to test out their vps service so a few days ago i signed up for one, still havent received it yet, which is strange given that in that time i had 1 dedicated, and then got another one as a replacement. its not looking good for hetzner and/or germany, I might have to call Trump lol

    What happens if you run the centmin.sh script like the below?

    Code:
    ./centmin.sh

    its strange because I tried that too, same result, I waited about 10 min then it actually loaded the centminmod menu up. I ran

    Code:
    yum-config-manager --save --setopt=varnish-4.1.skip_if_unavailable=true
    as I kept getting errors about it then rebooted the server 4 times and now it loads up centminmod right away. I still think this server also has some sort of connectivity issues, just not as pronounced as the last server.

    Theres also things that as far as I can tell don't even function properly and Im not certain why, for example nginx status page is enabled and refuses to work even though i configured it almost exactly like my ovh server which runs fine. I feel this is risky as I can't have a production server doing whatever it wants or deciding to seclude itself from the internet to take a nap.

    I even tried replacing the contents of the resolv file and added google's dns. I'll keep experimenting with this but I think I may cancel this server and ditch this company within a week.

    Just do a fresh Centmin Mod code replacement by wiping /usr/local/src/centminmod as outlined similar to update guide here for older than .07 releases.

    replace branchname with branch you want either 123.08stable or 123.09beta01
    Code (Text):
    branchname=123.09beta01
    cd /usr/local/src
    rm -rf centminmod*
    git clone -b ${branchname} --depth=1 https://github.com/centminmod/centminmod.git centminmod
    cd centminmod
    ./centmin.sh

    thanks @eva2000, they're looking at it now so i'll wait before I start doing anything,
