My friend's website http://wolf-peak.com is up and running on WordPress on CentOS7.

Here is my process for Apache on CentOS7 minimal

# install packages needed to run wordpress
yum -y install httpd;
yum -y install mariadb mariadb-server;
yum -y install php php-mysql wget nano;
systemctl enable httpd.service;
systemctl enable mariadb.service;
setenforce permissive;
systemctl start mariadb;
firewall-cmd --zone=public --add-port=http/tcp;
firewall-cmd --zone=public --add-port=http/tcp --permanent;
systemctl reload firewalld;
systemctl start httpd;

# create database and user for this website/domain
echo "CREATE DATABASE wp_yourdomain;" | mysql;
echo "CREATE USER 'wp_yourdomain'@'localhost' IDENTIFIED BY 'somerandompassword';" | mysql;
echo "GRANT ALL PRIVILEGES ON *.* TO 'wp_yourdomain'@'localhost';" | mysql;
echo "FLUSH PRIVILEGES;" | mysql;

# download wordpress
cd /opt;
wget https://wordpress.org/latest.tar.gz;
tar -xzvf latest.tar.gz;
chown -R apache:apache /opt/wordpress/;

# copy the wordpress directory to the domain folder desired
cp -R /opt/wordpress/ /opt/yourdomain/

# create the wp-config.php file and set the database information
cp /opt/yourdomain/wp-config-sample.php /opt/yourdomain/wp-config.php;

I guess I could load wordpress onto jaredbusch.com and post this there.

I mostly use mine for email.

No you don't. You use your gmail for everything, including NTG STUFF! Case and point: storage locker.

scottalanmiller

@ajstringham I'm not sure what you are trying to say.

The storage locker, for NTG Lab stuff, that you had here in Texas...you put a ton of different things as your Gmail when you should use your NTG email. I had a very interesting convo with @Minion-Queen once on it...

scottalanmiller

I only use Gmail when I need to make non-NTG accounts. I don't even read my Gmail, it's the spam account. It often exists in odd places because of companies having really bad account management where we felt it was dangerous to use the company account. I'm actually very careful about it.

A Former User

I never use a personal email for work use... Unless of course my former boss decides he thinks he needs to use it.

Not what I've heard.

Uh huh?

Here we go. i setup wordpress on jarebusch.com using the process above and i've put the latest version there.

We'll see how bad the comments spam up with no protection plugin in place. I have it set to all comments be moderated. I am curious to see how fast it gets spammy.

The site loads very quickly.

It is a clean CentOS 7 minimal install running in Server 2012 R2 With the Hyper-V role.
It is located in a data center in St. Louis.

There are umm 5 sites all running Wordpress on the VM. Said sites setup in the process of creating that guide.

Xmodulo now has a nice guide for actually doing LEMP on CentOS that is meant for real people, not just people looking to do a one liner challenge

The original post on my own blog was lost and is not only in the Internet Archive, so copying it here...

From May 14th, 2014:

We all know that installing WordPress on LAMP is super simple. A challenge was issued on Spiceworks to demonstrate how WordPress on LEMP (Nginx rather than Apache) could be easy on CentOS. So that challenge could not go unmet. So the goal here is to install, quickly and hopefully easily, WordPress on LEMP.

Assumption: Starting with CentOS 6.5 “Minimal” accepting all defaults. To make things easy, we will just log in as root (the password is set during the initial install.)

First, we won’t even assume that networking is working. Out of the box, CentOS Minimal leaves the network off. And we will assume that you don’t want to edit any files. So just run this command:

sed -i -e 's/no/yes/' /etc/sysconfig/network-scripts/ifcfg-eth0
service network restart
ifconfig eth0 | grep "inet addr" | cut -d":" -f2 | cut -d" " -f1

That second line will provide you your IP address so that you can SSH into the box. Yup, I’m making it that simple. So, assuming we’ve now been able to use SSH to connect to the box we should now be easily able to copy and paste everything from here on out.

yum -y install wget; cd /tmp; wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm; rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm; yum -y install nginx; chkconfig nginx on; rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm; yum -y install mysql mysql-server; rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm; chkconfig mysqld on; setenforce permissive; yum -y –enablerepo=remi install php-fpm php-mysql; sed -i -e s/apache/nginx/g /etc/php-fpm.d/www.conf; chkconfig php-fpm on; cd /opt; wget https://wordpress.org/latest.tar.gz; tar -xzvf latest.tar.gz; service mysqld start; echo “CREATE DATABASE wp” | mysql; echo “CREATE USER ‘wpuser’@’localhost’ IDENTIFIED BY ‘password';” | mysql; echo “GRANT ALL PRIVILEGES ON *.* TO ‘wpuser’@’localhost';” | mysql; echo “FLUSH PRIVILEGES;” | chown -R nginx:nginx /opt/wordpress/; iptables -I INPUT 1 -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT; iptables-save > /etc/sysconfig/iptables; service iptables reload; service php-fpm start; sed -i -e s’/index  index.html index.htm/index  index.php index.html/’ /etc/nginx/conf.d/default.conf; sed -i -e s’/\/usr\/share\/nginx\/html/\/opt\/wordpress/’ /etc/nginx/conf.d/default.conf; sed -i -e 0,/#loca/{s’/#loca/loca/’} /etc/nginx/conf.d/default.conf; sed -i -e s’/#    root           html/     root      \/opt\/wordpress/’ /etc/nginx/conf.d/default.conf; sed -i -e s’/#    fastcgi_pass/    fastcgi_pass/’ /etc/nginx/conf.d/default.conf; sed -i -e s’/#    fastcgi_index/    fastcgi_index/’ /etc/nginx/conf.d/default.conf; sed -i -e s’/#    fastcgi_param  SCRIPT_FILENAME  \/scripts$fastcgi/    fastcgi_param  SCRIPT_FILENAME  \/opt\/wordpress$fastcgi/’ /etc/nginx/conf.d/default.conf; sed -i -e s’/#    include        fastcgi_params/    include        fastcgi_params/’ /etc/nginx/conf.d/default.conf; echo ‘}’ >> /etc/nginx/conf.d/default.conf; service nginx restart; echo “All Done, You Can Log In Now”

And that is it. Just point your web browser to the same address that we looked up with the ifconfig command at the beginning and you should see WordPress awaiting your input to step you through the last bits of the setup. Just give it the database name, database username and password that we set in the script and you are done, my friend.

Alex Sage

You should add WP-cli support.

@JaredBusch said in The WordPress on CentOS LEMP Challenge:

Going to try this with a net CentOS 7 minimal install. I turned on networking at install and it was a good thing. The ifconfig script is not there in a minimal install. need to use "ip a sh" to see the config now. I haven't looked at the man for ip yet. I assume a is all and sh is show.

Also, reading through the script, if I use httpd instead of nginx I assume I do not need this command.
sed -i -e s/apache/nginx/g /etc/php-fpm.d/www.conf

and this command would be switched to httpd
chkconfig nginx on

They've replaced ifconfig with ip. I'm forcing myself to use ip till I get used to it and I can always fall back on ifconfig, or in the case of CentOS, just entering settings in /etc/sysconfig/network-scripts/interface file.
