The tutorials in this regard can be said to be a large number of searches, but they all have some defects. In practice, all kinds of pits are in order to step on fewer pits. This article will present the most comprehensive building tutorial for novices.
Installation environment
- Nginx1.2
- PHP7.x
- Mysql8.0
Installing Nginx
To add a CentOS 7 EPEL repository, run the following command:
yum install epel-release
Installing Nginx
yum install nginx
Start Nginx service
systemctl start nginx
Power on
sudo systemctl enable nginx
Install mysql8 0
Add mysql Library
yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
Install mysql
yum --enablerepo=mysql80-community install mysql-community-server
mysql start
systemctl start mysqld.service
Change root password Because in mysql8, the default password will be set when installing the database. We can use the following command to view the default password
grep 'A temporary password is generated for root@localhost' /var/log/mysqld.log |tail -1
Initialize database
sudo mysql_secure_installation
You will be prompted to enter the root password, which is the default password obtained in the previous step. Then enter the root password again and enter Y all the way. I don't know why the modified program can't connect and log in. Use the following command to modify the root password again.
mysql -u root -p use mysql; ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'youpassword'; systemctl restart mysqld #Restart MySQL
Install PHP
Installing the Remi repository
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
Check the PHP 7 + version available in the Remi repository
yum --disablerepo="*" --enablerepo="remi-safe" list php[7-9][0-9].x86_64
You will see this output
Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * remi-safe: mirrors.ukfast.co.uk Available Packages php70.x86_64 2.0-1.el7.remi remi-safe php71.x86_64 2.0-1.el7.remi remi-safe php72.x86_64 2.0-1.el7.remi remi-safe php73.x86_64 2.0-1.el7.remi remi-safe php74.x86_64 1.0-3.el7.remi remi-safe php80.x86_64 1.0-3.el7.remi
Enable the corresponding PHP Version (take 7.4 as an example)
sudo yum-config-manager --enable remi-php74
Install php
yum -y install php php-mysqlnd php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-zip php-cli php-fpm php-gd php-mysqlnd php-mbstring php-opcache php-pdo php-json
configuration file
Configuration PHP FPM file
vim /etc/php-fpm.d/www.conf The user and group variables are apache by default. We need to change these to nginx Find listen PHP FPM, which listens to specific hosts and ports over TCP. We want to change this setting to listen to local socket files because it will improve the overall performance of the server.
listen = /var/run/php-fpm/php-fpm.sock;
Finally, we need to change the owner and group settings of the socket file we just defined in the listen directive. Find listen owner,listen. Group and listen Mode instruction. These lines are commented out by default. By deleting; Uncomment with the leading symbol at the beginning of the line. Then, change the owner and group to nginx:
listen.owner = nginx listen.group = nginx listen.mode = 0660
Finally, restart PHP FPM
systemctl start php-fpm
Configure Nginx to handle PHP
The current configuration is unable to access php files. We still need a simple configuration. Nginx has a dedicated directory where we can define each managed site as a separate configuration file using a server block. This is similar to Apache's virtual host. In the default installation, this directory is empty. We will create a new file as the default PHP website on this server, which will overwrite / etc / nginx / nginx The default server block defined in the conf file. Open a new file in the / etc/nginx/conf.d directory
vim /etc/nginx/conf.d/default.conf
#The contents are as follows:
server {
listen 80; #The port can be modified by itself, such as 8080
server_name 192.168.x.x; #If there is no domain name, fill in the public IP or intranet IP directly
root /var/www/html; #Website Lu Jin
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www/html; #Website Lu Jin
}
#php configuration section
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}Restart Nginx to apply changes:
sudo systemctl restart nginx
Configure site directory user groups and permissions
At present, both php and nginx run as nginx, and sometimes the permissions of our directory are owned by root. So visit the website will appear 404. First, check the user groups of php and ngxin
ps -ef | grep php ps -ef | grep nginx
Finally, modify the user group permissions of the corresponding directory
chown -R nginx:nginx /var/www/blog
Then restart php and nginx again
Configure PATHINFO
Like Typecho, we need to enable PATHINFO. PATHINFO is not supported by default, so we need to change the configuration file of the host that supports PATHINFO.
location ~ ^(.+\.php)(.*)$ {
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
include fastcgi_params;
}And configure etc / PHP ini
cgi.fix_pathinfo=1
Finally, restart nginx and php There are so many problems at present. Let's talk about the problems later!
