1.Nginx Install
The first, Your update for Centos 8.
[root@DevopsRoles vagrant]# dnf update

[root@DevopsRoles vagrant]# dnf install nginx
# Set to start automatically at reboot
[root@DevopsRoles vagrant]# systemctl enable --now nginx
# Check status
[root@DevopsRoles vagrant]# systemctl status nginx
Firewall port setting HTTP (80) Allow HTTPS(443)
[root@DevopsRoles vagrant]# firewall-cmd --add-port=80/tcp --permanent

# After installation, familiar service start, and automatic start setting
[root@DevopsRoles vagrant]# systemctl start mysqld
[root@DevopsRoles vagrant]# systemctl enable mysqld
# The initial security settings of mysql
[root@DevopsRoles vagrant]# mysql_secure_installation
# Operation check
[root@DevopsRoles vagrant]# mysql -u root -p
3.Install PHP
[root@DevopsRoles vagrant]# dnf install php-fpm php-cli php-json php-opcache php-xml php-gd php-curl
# php is also set to start automatically
[root@DevopsRoles vagrant]# systemctl enable --now php-fpm
Extension php required to run WordPress on Centos 8
[root@DevopsRoles vagrant]# dnf install php-cli php-json php-opcache php-xml php-gd php-curl php-mysqlnd
4.Database Creation
[root@DevopsRoles vagrant]# mysql -u root -p
# db creation (name can be anything)
SQL> create database wordpressdb;
# Create user, set permissions and reflect settings
SQL> create user wpadmin@localhost identified by 'Stro123@.';
SQL> grant all on wordpressdb.* to wpadmin@localhost;
SQL> flush privileges;
SQL> quit
5.Install WordPress
# Download wordpress
[root@DevopsRoles vagrant]# wget https://wordpress.org/latest.tar.gz
# Create a folder for #wordpress
[root@DevopsRoles vagrant]# mkdir /usr/share/nginx/wp.devopsroles.com
# Decompress
[root@DevopsRoles vagrant]# tar xzf latest.tar.gz -C /usr/share/nginx/wp.devopsroles.com/ --strip-components=1
# Copy configuration file
[root@DevopsRoles vagrant]# cp /usr/share/nginx/wp.devopsroles.com/wp-config-sample.php /usr/share/nginx/wp.devopsroles.com/wp-config.php
# Open configuration file
[root@DevopsRoles vagrant]# vi /usr/share/nginx/wp.devopsroles.com/wp-config.php
Look like wp-config.php file as below:
/** MySQL database name */
define( 'DB_NAME', 'wordpressdb' );
/** MySQL database user name */
define( 'DB_USER', 'wpadmin' );
/** MySQL database password */
define( 'DB_PASSWORD', 'Stro123@.' );
/** MySQL hostname */
define( 'DB_HOST', 'localhost' );
/** Database character set when creating database table */
define( 'DB_CHARSET', 'utf8' );
/** Database collation (should not be changed in most cases) */
define( 'DB_COLLATE', '' );
Get the authentication unique key for WordPress.
curl -s https://api.wordpress.org/secret-key/1.1/salt/
Copy and paste the returned contents into wp-config.php
define('AUTH_KEY', 'balabal');
define('SECURE_AUTH_KEY', 'balabal');
define('LOGGED_IN_KEY', 'balabal');
define('NONCE_KEY', 'balabal');
define('AUTH_SALT', 'balabal');
define('SECURE_AUTH_SALT', 'balabal');
define('LOGGED_IN_SALT', 'balabal');
define('NONCE_SALT', 'balabal');
6.Nginx Settings
I have configured Nginx for WordPress with content as below:
vi /etc/nginx/conf.d/devopsroles.conf
server {
listen 80 default_server;
server_name devopsroles.com;
root /usr/share/nginx/wp.devopsroles.com;
access_log /var/log/nginx/access_devopsroles.com.log;
error_log /var/log/nginx/error_devopsroles.com.log;
index index.php;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_index index.php;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
