LNMP (linux,nginx,mariadb,php) deployment, the following default under root permissions, take Centos7 as an example.

Installation

• Installing NMP (nginx-mariadb-php)

yum install nginx mariadb-server php php-fpm

• Set the boot up and start the service immediately:

systemctl enable nginx mariadb php-fpm && systemctl start nginx mariadb php-fpm

• Can be installed phpMyAdmin easy to manage MARIADB database:

yum install phpmyadmin

Configuring the MARIADB Configuration

mysql_secure_installation

Enter > Follow the prompts to enter y> 2 password (not recommended no password) > enter > Follow the prompts to enter y> last appearance: Thanks for using mariadb!

PHP Configuration

Edit the /etc/php.ini file, locate the line like Session.save_path , remove the comment, and modify the following:

session.save_path = "/var/lib/php/session"

See if the Session Directory exists and if it does not exist, create it manually:

 
   
  

  
    
   
ls /var/lib/php/session
  
    
   
mkdir /var/lib/php/session
 
   
  

To ensure that permissions are met, change the Session Directory file permissions:

chown nginx:nginx /var/lib/php/session -R

phpMyAdmin Configuration

Copy the phpMyAdmin directory to the Nginx root directory, with the root directory/srv/web as an example:

cp /usr/share/phpMyAdmin/ /srv/web/phpMyAdmin;

！ Description: CentOS installs the phpMyAdmin in the/usr/share/directory, archlinux in the/usr/share/webapps/directory, the rest of the distribution according to the sentiment operation.

phpMyAdmin can be changed to phpMyAdmin or other easy-to-operate names. If you change the name, then the Nginx configuration should be changed to the corresponding directory name.

X can also be soft-linked phpMyAdmin directory:

ln -sf /usr/share/phpMyAdmin /srv/web/phpMyAdmin

PHP-FPM Configuration

Edit/etc/php-fpm.d/www.conf as follows:

 
   
  

  
    
   
user = nginx #修改用户为nginx
  
    
   
group = nginx #修改组为nginx
 
   
  

Nginx Configuration

Edit the. conf file under/etc/nginx/conf.d/, if/etc/nginx/conf.d/does not have any conf files under it, create a new. conf file, such as website.conf, as follows (as modified by the situation):

  
 

   
  

  
server {
   
  

  
listen 80;
   
  

  
＃此处server_name后填写域名
   
  

  
server_name www.xxx.com; 
   
  

  
＃ngnix默认的主目录，可根据具体情况修改
   
  

  
root /srv/web; 
   
  

  
# 添加上index.php
   
  

  
index index.php index.html index.htm;
   
  

  
 # php解析
   
  

  
location ~ \.php$ {
   
  

  
fastcgi_pass 127.0.0.1:9000;
   
  

  
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   
  

  
include fastcgi_params;
   
  

  
}
   
  

  
}
  
 

* Prohibit direct access to websites via IP, prevent malicious parsing, add a new server:

 
   
  

  
    
   
server{
  
    
   
 listen 80;
  
    
   
 # ip处填写服务器ip地址
  
    
   
 server_name: ip;
  
    
   
 return 444;
  
    
   
}
 
   
  

When accessed via an IP address, a 444http status code is returned, the server does not return information to the client, and the connection is closed.
*

* Permissions Issues : Nginx home directory permissions require file Permissions 644, folder 755, the owner of Nginx execution User (the default is Nginx group Nginx), the root directory for/srv/web as an example:

  
 

   
  

  
chown -R nginx.nginx /srv/web/
   
  

  
find /srv/web/ -type f -exec chmod 644 {} \;
   
  

  
find /srv/web/ -type d -exec chmod 755 {} \;
  
 

The 3 commands can be written to BASHRC in an alias store for easy execution, such as writing into/ETC/BASHRC,NANO.BASHRC, and then writing to the end of the file:
alias webroot=‘chown -R nginx.nginx /srv/web/ && find /srv/web/ -type d -exec chmod 755 {} \; && find /srv/web/ -type f -exec chmod 644 {} \;‘
Save and execute SOURCE/ETC/BASHRC to make it effective. In the future, if you encounter permissions problems, just execute webroot.

Test

After the configuration is complete, restart all services before testing:

systemctl restart nginx mariadb php-fpm

• Test Nginx:

nginx -t

Success returns the following:

Nginx:the configuration file/etc/nginx/nginx.conf syntax is OK
Nginx:configuration file/etc/nginx/nginx.conf Test is successful

• Log in to the website to test, open the domain name or IP in the browser.

• Test PHP parsing:
  Add the phpinfo.php test file to the root directory with the contents:

 
   
  

  
    
   
<?php
  
    
   
phpinfo();
  
    
   
?>
 
   
  

After saving, open the Web site, for example, the URL is xxx.com, browse xxx.com/info.php, you can see the PHP details page.

• MARIADB test, in the main directory under the phpMyAdmin name unchanged as an example, such as the URL is xxx.com, browse xxx.com/phpmyadmin into the mariadb login page, user name root, password is mariadb configuration input password.
