         yum install httpd httpd-devel mariadb-server mariadb-devel php php-mysql php-devel
 

7. systemctl restart {httpd,mariadb}
8. systemctl status httpd

9. systemctl status mariadb

10. mysqladmin -u root password 000000
11. mysqladmin -u root p000000
12. exit

13.ss -tnmlp | grep mysql
ss -tnmlp | grep httpd

14.mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.confbak
