No PHP MySQLi functions available. Please ensure that the PHP MySQL module is loaded

First, I have read the post "Please read before posting".

I am sure the error I am getting is simple enough not to run the analyzer, but sadly not simple enough for me to fix it.

I have a fresh CentOs 7.6 VPS from DigitalOcean, and these are the only command I run in it.

These are the command I run

Code:

# Security Components
yum install fail2ban jailkit

# Database Components
yum install mariadb-server mariadb-libs mariadb
firewall-cmd --zone=public --permanent --add-port=mysql/tcp
firewall-cmd --reload
# Web Components
yum install nginx pure-ftpd certbot
systemctl enable nginx
systemctl enable pure-ftpd
firewall-cmd --zone=public --permanent --add-port=http/tcp
firewall-cmd --zone=public --permanent --add-port=https/tcp
firewall-cmd --reload

# Mail Components
yum install postfix dovecot postgrey spamassassin amavisd-new getmail roundcubemail mailx svn

systemctl enable dovecot
systemctl enable postfix
systemctl enable postgrey
systemctl enable amavisd

firewall-cmd --zone=public --permanent --add-port=imaps/tcp
firewall-cmd --zone=public --permanent --add-port=pop3s/tcp
firewall-cmd --zone=public --permanent --add-port=smtp/tcp
firewall-cmd --zone=public --permanent --add-port=smtps/tcp
firewall-cmd --reload

cd /usr/share/roundcubemail/plugins
svn co https://github.com/w2c/ispconfig3_roundcube/trunk/ .
cp ./ispconfig3_account/config/config.inc.php.dist ./ispconfig3_account/config/config.inc.php

# DNS Components
yum install bind
systemctl enable named
firewall-cmd --zone=public --permanent --add-port=53/tcp
firewall-cmd --zone=public --permanent --add-port=53/udp
firewall-cmd --reload
Installation
cd /root

wget https://ispconfig.org/downloads/ISPConfig-3.1.11.tar.gz

tar xfv ISPConfig-3.1.11.tar.gz

cd ispconfig3_install/install
php install.php

And you can see at this point, after I run the install, choose language, standard, then I get the error:

Code:

No PHP MySQLi functions available. Please ensure that the PHP MySQL module is loaded

So, what is the solution to this? I am thinking I should maybe install php7.3 along with the mysql-ext, but coming from plesk, cpanel, the php, nginx install is usually handled my the control panel, all the cpanel asks for is a fresh VPS.

So in this case, I don't want to install anything that might be installed by the cpanel itself.

 

Ok, I gave the link you provided a try, and I have encountered some errors, and this one is the where I have stopped, because it simply won't work.

Code:

[root@server ~]# mount -o remount /var
mount: /etc/fstab: parse error: ignore entry at line 25.
mount: /var not mounted or bad option

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
[root@server ~]#

Here is the log from the msg

I followed and wrote down every line of command on a fresh VPS from digitalocean.

I don't really like to complain on a quality of opensource software, which is basically given for free, but please try the commands yourself first before sharing them. If the VPS was old, had issues and this guide didn't work, I would understand, but this is just a new VPS I created solely for installing IPSConfig and the fact the guide does not work and wastes time is really upsetting.

 

Actually never mind, if it is hard to finish the first page instruction without errors, it's most likely impossible to complete all the three pages. Just make sure to try and update the manual yourself, so no one wastes 2-3 days of pain
