Setup WordPress on Centos/Fedora with MySQL and PHP

3 min read

In this article we will setup WordPress from scratch in just a few easy steps. I will use a vps with centos 7.

Step 1) Install Apache web server

yum -y install httpd
systemctl start httpd.service
systemctl enable httpd.service

Step 2) Install PHP 5.6

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum -y install php56w php56w-opcache php56w-mysql php56w-xml
systemctl restart httpd.service

Step 3) Install Mysql 5.6

yum -y install http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
yum -y install mysql-community-server
systemctl start mysqld.service
systemctl enable mysqld.service

Step 4) Install WordPress

1 – Download latest WordPress

cd /var/www/html
wget https://wordpress.org/latest.zip
unzip latest.zip
rm -rf latest.zip
cp -rf wordpress/* /var/www/html/
rm -rf wordpress/

2 – Setup permissions:

chown -R apache:apache /var/www/html/*
chown  apache:apache /var/www/html

3 – Create MySQL Database, we will call ours ‘wordpress’, you can replace the word ‘wordpress’ below with whatever you would like your database to be called

mysqladmin create wordpress

Step 5) Point your browser to http://Your-Server-IP and you will see the WordPress installation page.

If nothing loads, first let’s verify our webserver is working:

[root@wordpress html]# ps ax | grep http
 566 ? Ss 0:00 /usr/sbin/httpd -DFOREGROUND
 568 ? S 0:00 /usr/sbin/httpd -DFOREGROUND
 988 pts/0 S+ 0:00 grep --color=auto http

If you see at least one “/usr/sbin/httpd” line, this means our webserver is working. The most likely cause then would be our firewall blocking the access to our webserver. Let’s check it out:

[root@wordpress ~]# firewall-cmd --state
not running

If we get ‘not running’, lets then start the firewall:

[root@wordpress ~]# systemctl start firewalld

[root@wordpress ~]

# systemctl enable firewalld Created symlink from /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service to /usr/lib/systemd/system/firewalld.service. Created symlink from /etc/systemd/system/basic.target.wants/firewalld.service to /usr/lib/systemd/system/firewalld.service.

now lets run again:

[root@wordpress ~]# firewall-cmd --state
running

We should now get ‘running’ which indicates the firewall is running correctly.

Let’s get our default zone:

[root@wordpress ~]# firewall-cmd --get-default-zone
public

Let’s now get our active zone:

[root@wordpress ~]# firewall-cmd --get-active-zones

[root@wordpress ~]

#

If you get nothing when running the above command, this means we need to associate our zone with our network interface. Otherwise go to “Let’s now allow our webserver through the firewall”.

Let’s get the name of our network interface

[root@wordpress ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
 inet 127.0.0.1/8 scope host lo
 inet6 ::1/128 scope host
 valid_lft forever preferred_lft forever
2: gre0: <NOARP> mtu 1476 qdisc noop state DOWN
 link/gre 0.0.0.0 brd 0.0.0.0
3: gretap0: <BROADCAST,MULTICAST> mtu 1476 qdisc noop state DOWN qlen 1000
 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
4: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
 link/void
 inet 127.0.0.1/32 scope host venet0
 inet 162.212.152.69/32 brd 162.212.152.69 scope global venet0:0

My network interface is called venet0, since this is the one with my internet IP, yours might be called ethX, enp0sX,etc

Let’s associate our network interface with our firewall zone

firewall-cmd --permanent --zone=public --change-interface=venet0

Let’s now allow our webserver through the firewall:

firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --reload

Now go back to your browser and refresh, we should now get the wordpress install page.

On the first screen we will select our desired Language and hit Continue, on the second Screen hist Let’s Go

Now let’s fill the boxes, once you are done they should look exactly like below:

Database NameThe name of the database you want to use with WordPress.
UsernameYour database username.
PasswordYour database password.
Database HostYou should be able to get this info from your web host, if localhost doesn’t work.
Table PrefixIf you want to run multiple WordPress installations in a single database, change this.

Database name is the name of the database we created in step 3, if you gave your database a different name then wordpress, please change the first box.

Username & Password fields are the login for our local mysql database. Since we have not setup a password for it, we leave the password field blank, while username is the default one which is root.

Now click Submit. You will be taken to the next step:
