    are you logging in as root user or a sudo user account ?

    what is output for these commands

    Code (Text):
    ls -lah /usr/local/bin/dmotd
    id


    You need to log in as root user

    guess that's where the problem is.. centmin mod assumes root user login

    so will have to come up with fix for it in 123.09beta01

    however, sudo to root user should be able to run centmin.sh

    how did you setup the sudo user ? list the steps

    strange with 123.09beta01 it at least supports sudo after install unlike 123.08stable which doesn't support sudo

    but you should be able to sudo root user fine, i just tested it without problems

    i tested login as sudo user = motd shows up fine

    i tested sudo su and switch to root user fine

    Code (Text):
    sudo su

    as does
    Code (Text):
    su

    probably need to double check if you setup sudo user properly

    fyi, 123.09beta01 has a tools/addsudousers.sh script which can add and setup sudo users too ;)

    Code (Text):
    tools/addsudousers.sh desiredusername

    sadly it again came out -bash: /usr/local/bin/dmotd: Permission denied.

    does this command affect?

    chown -R nginx:ftpusername /home/nginx

    chmod -R 770 /home/nginx

    find ./ -type f -exec chmod -v 660 {} \;

    chmod -R 644 /home/nginx/domains/mydomain.com/public/.htaccess

    that will mess up file permssions for nginx served sites !

    file is owned by root so with proper sudo user it should work

    if you log in as root user does it have same issue ? if not then it's your sudo user setup issue. I've tested with sudo user and no problems with dmotd permissions

    .htaccess isn't supported in nginx so no usage using .htaccess

    To fix nginx incorrect permissions you did use ssh commands
    Code (Text):
    chown -R nginx:nginx /home/nginx
    chmod g+s /home/nginx
    chmod g+s /home/nginx/domains/

    so maybe as root user, setup a 2nd sudo user via tools/addsuousers.sh and see if logging in with this sudo user works

    Use the pure-ftpd virtual ftp user generated with your account Pure-FTPD Virtual FTP Users - CentminMod.com LEMP Nginx web stack for CentOS
    • Did you let the script generate a password for you or set your own ?
    • Did you make sure to enable explicit TLS/SSL mode and enable PASV passive mode like in 1st post here.
    • Which FTP client ? As not all FTP clients support FTP explicit TLS/SSL mode only clients listed at bottom of this post.
    • If you are having trouble with logging in using the generated pure-ftpd username and password, you can try changing the password for the pure-ftpd username with instructions outlined at Pure-FTPD Virtual FTP Users - CentminMod.com LEMP Nginx web stack for CentOS
    • Check if you're ISP IP address is being blocked by CSF Firewall. See FAQ items 40 & 41.

    Having a similar issue. I was given a new server without root access. However, the account provided to me was added to sudoer list so I should not have any issue.
    I was able to sudo everything and install centminmod, add a vhost, etc,

    There are few things that are not working with sudoer account
    1) sudo: cmdir: command not found
    2) I can't go to the pubic folder of the vhost I just created.
    sudo cd /home/nginx/domains/xxx/public
    This will not do anything
