This article mainly introduces how to build a PHP server environment on CentOS. It briefly describes the installation of Apache, mysql, php environment and related test codes on the CentOS platform. It is very simple and practical. Friends who need it can refer to it. I hope it can help everyone. .

1. Install apache first:

##

yum install httpd

Configure ServerName

vi /etc/httpd/conf/httpd.conf

Change

#ServerName www.example.com:80 to ServerName localhost:80

For the external machine, enter the IP of the server at this time For the address, you should see the apache service page. There is no need to enter the port. Apache uses port 80 by default.

If it cannot be opened, port 80 may not be open for external access. Check:

/etc/init.d/iptables status

Whether there is information such as 80 or so after it, if not, open it. Pay attention to the position and statement state. There are two horizontal bars in front of the report--:

vim /etc/sysconfig/iptables

Join:

-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

Then restart and save the firewall:

service iptables restart
/etc/rc.d/init.d/iptables save

Check again whether it is enabled:

/etc/init.d/iptables status

Start apache:

/etc/init.d/httpd start

##

yum install mysql mysql-server
