Edit the php configuration file and edit the following changes in the file and save it.

[root@linuxhelp ~]#  vim /etc/php.ini
Output:
max_input_vars = 1500
max_execution_time = 240

After extracting the file move it to this location

[root@linuxhelp ~] # mv typo3_src-8.7.3 /var/www/typo3

Enter into the directory.

[root@linuxhelp ~]# cd /var/www/

Rename the _.htaccess file by running the following command.

[root@linuxhelp ~]# mv typo3/_.htaccess typo3/.htaccess

Change the ownership and permission of file in typo3 directory.

[root@linuxhelp ~]# chown -R apache:apache /var/www/typo3

Configure your Apache VirtualHost, and for that you need to open a .conf file for Typo3 CMS. Use the following command to open it.

[root@linuxhelp ~]# vim /etc/httpd/conf.d/typo3.conf 
<Virtualhost *:80>
        Servername www.linuxhelp1.com
        Documentroot /var/www/typo3
</Virtualhost>

Configur the host entry by using the following command

[root@linuxhelp ~]# vim /etc/hosts
<ipaddress>      <domain name>

Create a empty file in typo3 directory and while installing the typo3 application, it will automatically get the file.

[root@linuxhelp ~]# touch /var/www/typo3/FIRST_INSTALL

Then we need to restart the apache server

[root@linuxhelp ~]# systemctl restart httpd

Switch over to a browser and enter your domain name. The installation page appears on the screen. Click continue.
