CentOS7 Installation and Configuration LEMP (Nginx/PHP-FPM 5.6/MySQL 5.5) Website Environment Procedure

The Nginx system environment architecture will be adopted for the general large-scale website building environment. Relatively speaking, it bears more threads and pressure than Apache. However, for general blogs and websites, the Apache environment is also sufficient. In previous related articles, whether it is LNMP one button installation package, LEMP one button package, AMH and other web panels, they all use NGINX to build a website environment.

In this article, Lao Zuo has compiled an article based on the latest CentOS7 system to build and apply the website environment applicable to Nginx/PHP-FPM 5.6/MySQL 5.5. If you also like tossing about, you can try the following content. The article is translated from overseas and tested to be complete.

First, install EPEL and REMI library files

rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Second, install Nginx

yum install nginx -y

Startup and setting startup

systemctl start nginx
systemctl enable nginx

Set the firewall to open port 80

firewall-cmd --zone=public --add-port=80/tcp --permanent$ sudo firewall-cmd --reload

Here we have installed NGINX. We can open the IP address browser and see the successful NGINX installation interface prompt.

Third, install MariaDB 5.5

yum --enablerepo=remi,remi-php56 install mariadb-server mariadb -y

Start and set the startup

systemctl start mariadb
systemctl enable mariadb

Set database security

/usr/bin/mysql_secure_installation

Execute the above script. According to the prompts, we need to set the database security and delete anonymous users.

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE!   PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
... Success!

Cleaning up...

All done!   If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Fourth, install PHP fpm 5.6

yum --enablerepo=remi,remi-php56 install php-fpm php-common php-mysql php-opcache php-pear php-gd php-devel php-mbstring php-mcrypt php-cli php-pdo php-xml -y

Startup and Startup

service php-fpm start
chkconfig php-fpm on

Fifth, configure Nginx

Now that we have installed nginx, mariadb, and php fpm, we need to configure Nginx

A - Configure the/etc/nginx/nginx.conf file

user  nginx;
worker_processes  1;

Worker_processes indicates the number of CPU cores of the current VPS/server. We can check and modify it through grep ^ processor/proc/cpuinfo | wc - l.

B - Check to start sendfile, tcp_nopush, gzip, and add INDEX PHP file

     sendfile        on;
tcp_nopush     on;
#keepalive_timeout  0;
keepalive_timeout  65;
gzip  on;
index   index.php index.html index.htm;

Sixth, add sites and set files

vi /etc/nginx/conf.d/laozuo_org.conf

When adding a site, we'd better use the domain name to check and remember it.

server {
listen your_public_ip_address:80;
server_name  www.laozuo.org;
root /var/www/www.laozuo.org;
index index.php index.html index.htm;

charset utf-8;

location / {
}

location = /robots.txt { allow all; access_log off; log_not_found off; }
location = /favicon.ico { allow all; access_log off; log_not_found off; }

error_page 401 /401.html;
error_page 403 /403.html;
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;

location ~ \.php$ {
root           /var/www/www.laozuo.org;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;
fastcgi_buffer_size 4K;
fastcgi_buffers 128 4k;
fastcgi_connect_timeout 50;
fastcgi_send_timeout 40;
fastcgi_read_timeout 40;
try_files $uri =404;
fastcgi_split_path_info ^(.+\. php)(/.+)$;
include        fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
# location ~ /\.ht {
#     deny  all;
# }
}

Enter the corresponding configuration file.

If there is no/var/www/www.laozuo.org folder, we need to give permission to add and configure settings.

mkdir /var/www/www.laozuo.org
chmod 777 /var/www/www.laozuo.org

Finally, let's start Nginx

systemctl restart nginx

If it fails to start, you can use "systemctl status nginx. service" to check what the problem is and then modify it accordingly.

To sum up, we can upload the program in the created folder. If you need to have databases such as MYSQL, we can install them separately. We can also refer to“ Debian installs LEMP (Linux/NGinx/MySQL/PHP) to build a site environment "Article installation.
