Install nginx dependencies

[root@localhost ~]# yum -y install pcre-devel zlib-devel

Create an administrative nginx user (used to run nginx)

[root@localhost ~]# useradd -M -s /sbin/nologin nginx

- `useradd`: command to create a user.

- `-M`: Indicates not to create the user's home directory.

- `-s /sbin/nologin`: Specify the user's login shell as `/sbin/nologin`, which means that the user cannot log in to the system through the login shell. It is usually used to create a system service account.

- `nginx`: the username of the new user.

To sum up, the function of this command is to create a user named `nginx`, but not create its home directory, and set its login shell to `/sbin/nologin`, which is usually used to create a system service account

Then drag the prepared nginx source code package into the virtual machine

Unpack

[root@localhost ~]# tar xf nginx-1.16.0.tar.gz -C /usr/src

Enter the unzipped nginx directory

[root@localhost ~]# cd /usr/src/nginx-1.16.0/

Configure nginx

[root@localhost nginx-1.16.0]# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --user=nginx

By executing this command, you can compile and install the Nginx server with the HTTP stub status module, install it in the `/usr/local/nginx` directory, and specify the user where Nginx runs as `nginx`

If you need other dependencies during the installation process, you can choose to install them yourself.

yum -y install gcc-c++

yum -y install pcre-devel

yum -y install zlib-devel

Compile and install

[root@localhost nginx-1.16.0]# make && make install

Optimize Nginx command and make a command link

[root@localhost ~]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/

Optimize Nginx commands

[root@localhost ~]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/

Check the configuration file for errors

[root@localhost ~]# nginx -t

[root@localhost etc]# vim /etc/init.d/nginx ——Enter nginx script

[root@localhost ~]# chmod +x /etc/init.d/nginx

[root@localhost ~]# chkconfig --add nginx

Install mysql database

First check whether there are libaio dependency packages and install them if not.

[root@localhost conf]# yum -y install libaio

Upload the MySQL binary installation package for binary installation

Unzip

[root@localhost ~]# tar xf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz -C /usr/local

[root@localhost ~]# cd /usr/local/

change name

[root@localhost local]# mv mysql-5.7.24-linux-glibc2.12-x86_64/ /usr/local/mysql

Create a system user to run it

[root@localhost local]# useradd -s /sbin/nologin mysql

cd to /usr/local and change mysql permissions to the user we just created

[root@localhost ~]# cd /usr/local/

[root@localhost ~]# chown -R mysql:mysql mysql

Initialize database to generate password

[root@localhost ~]# /usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize

Modify configuration file

[root@localhost mysql]# vim /etc/my.cnf

[mysqld]

datadir=/usr/local/mysql/data

socket=/tmp/mysql.sock

[mysqld_safe]

log-error=/usr/local/mysql/data/mysql.log

pid-file=/usr/local/mysql/data/mysql.pid

To restart the service, first cd to mysql and then execute the restart command.

[root@localhost ~]# cd /usr/local/mysql

[root@localhost mysql]# ./support-files/mysql.server start

Add execution permissions to the script

[root@localhost mysql]# chmod +x /etc/init.d/mysqld

start up

[root@localhost ~]# systemctl start mysqld

Make command connection

[root@localhost ~]# ln -s /usr/local/mysql/bin/* /usr/bin/

Change MySQL password

[root@localhost mysql]# mysqladmin -uroot -p'ay_iLLjr7eRB' password 123456

Install PHP

Install dependency packages

[root@localhost ~]# yum -y install gd libxml2-devel.x86_64 libjpeg-devel libpng-devel

Drag the PHP source code package into the virtual machine

Unzip

[root@localhost ~]# tar xf php-5.6.39.tar.gz -C /usr/src

cd into the PHP directory

[root@localhost ~]# cd /usr/src/php-5.6.39/

Then compile and install

[root@localhost php-5.6.39]# ./configure --prefix=/usr/local/php5 --with-gd --with-zlib --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-config-file-path=/usr/local/php5 --enable-mbstring --enable-fpm --with-jbeg-dir=/usr/lib && make && make install

Copy the main configuration file

[root@localhost php-5.6.39]# cp php.ini-production /usr/local/php5/php.ini

Then do command optimization

[root@localhost php-5.6.39]# ln -s /usr/local/php5/bin/* /usr/local/bin/

[root@localhost php-5.6.39]# ln -s /usr/local/php5/sbin/* /usr/local/sbin/

Drag this package to the root of the virtual machine

Unzip

[root@localhost ~]# tar xf zend-loader-php5.6-linux-x86_64_update1.tar.gz

cd to its path

cd zend-loader-php5.6-linux-x86_64/

copy

[root@localhost zend-loader-php5.6-linux-x86_64]#

cp ZendGuardLoader.so /usr/local/php5/lib/php

Enter the php configuration file

[root@localhost zend-loader-php5.6-linux-x86_64]# vim /usr/local/php5/php.ini

On the last line write the adder's

zend_extension=/usr/local/php5/lib/php/ZendGuardLoader.so

zend_loader.enable=1

Go to etc

[root@localhost zend-loader-php5.6-linux-x86_64]# cd /usr/local/php5/etc/

[root@localhost etc]# ls

Adjust and rename

[root@localhost etc]# mv php-fpm.conf.default php-fpm.conf

Enter the php configuration file

[root@localhost etc]# vim php-fpm.conf

Modify the content of the following lines

149 user = php

150 group = php

241 pm.max_children = 50

246 pm.start_servers = 20

251 pm.min_spare_servers = 5

256 pm.max_spare_servers = 35

Create php user

[root@localhost etc]# useradd -M -s /sbin/nologin php

start up

[root@localhost etc]# /usr/local/sbin/php-fpm

Modify nginx configuration file

[root@localhost html]# vim /usr/local/nginx/conf/nginx.conf

Now change the username in the first line to nginx

user nginx;
worker_processes 1;

add a location

location ~ \.php$ {

            root html;

            fastcgi_pass 127.0.0.1:9000;
