    Does the nginx config still pass the test? nginx -t ?

    I have fixed it by recompiling Nginx.
    Without custom_config.inc.

    Thanks Matt.

    What cpu does new server have? Did you do fresh 123.09beta01 install? Or copy over nginx binary from old server?

    Try setting CLANG='y' in persistent config file /etc/centminmod/custom_config.inc and recompile nginx via centmin.sh menu option 4

    Oh did you do a Linode clone or migrate via Linode's feature to move entire server data from one host node to another host node ? That could explain the error as nginx and php can be optionally setup to use intel optimised compiler and that is tied to the specific cpu model used on server. So when you use Linode's own migrate feature, you copied everything from one host node to another host node but they had different cpu models, so the nginx and maybe php binary are no longer working for the changed cpu model until you do centmin.sh menu option 4 and 5 recompiles.

    Overlooked that this can be a usage scenario encountered on cloud hosting providers. Will have to add to 123.09beta01 a way to track initial installed cpu model and check if cpu model changes to alert users to recompile nginx and php if required.

    Still the old one I think.
    Both no.

    99% the same with this: gist:dc815286195eece5aff3cdbecd5d9585 · GitHub

    Most likely reason is due to different cpu models you could of had E5-2680v3 or E5-2697v4 and switched to E5-2680v2 ? Could also be due to using DEVTOOLSETSIX='y' in customconfig.inc and new server not having GCC 6.2.1 installed yet ?

    what's ouput on new server for these 2 commands
    Code (Text):
    /opt/rh/devtoolset-6/root/usr/bin/gcc --version

    Code (Text):
    /opt/rh/devtoolset-6/root/usr/bin/g++ --version

    It's the same for PHP after migration, it doesn't start.
    But after I recompile it still using the old custom_config it works.
    Nginx only resolve when I recompile it without custom_config first.

    it's probably one of the custom_config.inc set settings then for yours gist:dc815286195eece5aff3cdbecd5d9585 · GitHub

    for nginx just set these 3 in persistent config /etc/centminmod/custom_config.inc and recompile nginx via centmin.sh menu option 4 and see
    Code (Text):
    CLANG='n'
DEVTOOLSETSIX='y'
NGINX_DEVTOOLSETGCC='y'

    and see if that works, then would have to systematically troubleshoot some of the other custom config settings you set on subsequent nginx recompile tests

    could be devtoolset-6 GCC 6.2.1 wasn't installed immediately after move but was after recompile with no custom_config.inc settings ? check when devtoolset-6 was installed
    Code (Text):
    yum history info devtoolset-6-gcc
