Detailed explanation of LNMP construction process

LNMP Detailed explanation of the construction process , Verification and establishment Forum

One 、 install Nginx service

preparation ： Turn off firewalls and security

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

1、 Install dependency packages

yum -y install pcre-devel zlib-devel gcc gcc-c++ make

2、 Create a running user

(Nginx The service program defaults to nobody Identity running , It is recommended to create a special user account for it , In order to more accurately control its access rights ）
useradd -M -s /sbin/nologin nginx

3、 Compilation and installation

cd /opt
# Drag in the package
tar zxvf nginx-1.12.0.tar.gz -C /opt/ # decompression

cd nginx-1.12.0/ # Switch to path
./configure
–prefix=/usr/local/nginx \ # Appoint nginx Installation path for
–user=nginx \ # Specify user name
–group=nginx \ # Specify the group name
–with-http_stub_status_module # Enable http_stub_status_module Module to support State Statistics

make -j4 && make install

./configure
–prefix=/usr/local/nginx
–user=nginx
–group=nginx
–with-http_stub_status_module

4、 Optimize the path

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ # Let the system recognize nginx Operation command of

5、 add to Nginx system service

vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecrReload=/bin/kill -s HUP $MAINPID
ExecrStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

6、 Test page : Firefox

Enter this machine IP：192.168.80.77

Add ： start-up 、 stop it nginx service
nginx -t # Check that the configuration file is configured correctly
nginx # start-up
cat /usr/local/nginx/logs/nginx.pid # To look at first nginx Of PID Number
kill -3 <PID Number >
kill -s QUIT <PID Number > # stop it
killall -3 nginx
killall -s QUIT nginx

Two 、 install MySQL service

1、 install Mysql Environment dependent packages

yum -y install
gcc
gcc-c++
ncurses \ # Dynamic library of graphic interaction function under character terminal
ncurses-devel \ #ncurses Development kit
bison \ # parsers
cmake #mysql Need to use cmake Compilation and installation

yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake

2、 Create a running user

useradd -M -s /sbin/nologin mysql

3、 Compilation and installation

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz

cd /opt/mysql-5.7.20/

cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock
-DSYSCONFDIR=/etc
-DSYSTEMD_PID_DIR=/usr/local/mysql
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DWITH_EXTRA_CHARSETS=all
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
-DMYSQL_DATADIR=/usr/local/mysql/data
-DWITH_BOOST=boost
-DWITH_SYSTEMD=1

make -j 4 && make install # Compilation and installation

4、 modify mysql The configuration file

vim /etc/my.cnf

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock
[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

5、 change mysql The primary group of the installation directory and configuration files

chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

6、 Set the path environment variable

echo ‘export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH’ >> /etc/profile
source /etc/profile

7、 Initialize datalization

cd /usr/local/mysql/bin/
./mysqld
–initialize-insecure
–user=mysql
–basedir=/usr/local/mysql
–datadir=/usr/local/mysql/data

8、 add to mysqld system service

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/

systemctl daemon-reload

systemctl start mysqld.service
systemctl enable mysqld

9、 add to mysql Login password for

mysqladmin -u root -p password “abc123” ## to root Set the password to abc123, The prompt is the original password （ It's empty ）

10、 Authorize remote login

mysql -u root -p
grant all privileges on . to ‘root’@‘%’ identified by ‘abc123’;
# grant root Users can log in remotely at all terminals , The password used is abc123, And all databases and all tables have operation permissions

show databases; # View the existing database

quit sign out

3、 ... and 、 Installation configuration PHP Analyze the environment

1、 Install environment dependency package

yum -y install gd
libjpeg libjpeg-devel
libpng libpng-devel
freetype freetype-devel
libxml2 libxml2-devel
zlib zlib-devel
curl curl-devel
openssl openssl-devel

2、 Compilation and installation

cd /opt
tar jxvf php-7.1.10.tar.bz2

cd ./php-7.1.10/
./configure
–prefix=/usr/local/php
–with-mysql-sock=/usr/local/mysql/mysql.sock
–with-mysqli
–with-zlib
–with-curl
–with-gd
–with-jpeg-dir
–with-png-dir
–with-freetype-dir
–with-openssl
–enable-fpm
–enable-mbstring
–enable-xml
–enable-session
–enable-ftp
–enable-pdo
–enable-tokenizer
–enable-zip

make -j4 && make install

3、 Path optimization

ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/

4、 adjustment PHP The configuration file

PHP There are three profiles
php.ini（ Master profile ）
php-fpm.conf（ Process service profile ）
www.conf（ Extended profile ）
Adjust the main profile php.ini ：

Adjust the process service profile php-fpm.conf ：

cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
#17 Line uncomment “;”
pid = run/php-fpm.pid

Adjust the extended profile www.conf :

cd /usr/local/php/etc/php-fpm.d
cp www.conf.default www.conf

5、 start-up php-fpm

PHP-FPM(FastCGI Process Manager:FastCGI Process Manager ) It's a PHPFastCGI Manager , because Nginx The server can't handle dynamic pages , Need by Nginx Give the dynamic request to php-fpm Process

cd /usr/local/php/sbin/
php-fpm -c /usr/local/php/lib/php.ini
netstat -natp | grep 9000

6、 To configure Nginx Support PHP analysis

vim /usr/local/nginx/conf/nginx.conf
##65 Line uncomment modify
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
# take /scripts It is amended as follows nginx The working directory of is changed to /usr/local/nginx/html
include fastcgi_params;
}

systemctl restart nginx.service

7、 verification PHP Test page

vim /usr/local/nginx/html/index.php

<?php phpinfo(); ?>

Browser access ：http://192.168.80.77/index.php

8、 Verify that the database is working properly

mysql -u root -p
CREATE DATABASE bbs;
GRANT all ON bbs.* TO ‘bbsuser’@‘%’ IDENTIFIED BY ‘admin123’;
flush privileges;
show databases; # See what databases are

vim /usr/local/nginx/html/index.php

<?php $link=mysqli_connect('192.168.80.77','bbsuser','admin123'); if($link) echo "wangdachu!"; else echo "fail!!" ?>

[ Failed to transfer the external chain picture , The origin station may have anti-theft chain mechanism , It is suggested to save the pictures and upload them directly (img-7VForyXS-1658731635280)(C:\Users\YU\AppData\Roaming\Typora\typora-user-images\image-20220725142748517.png)]

Y ‘admin123’;
flush privileges;
show databases; # See what databases are

vim /usr/local/nginx/html/index.php

<?php $link=mysqli_connect('192.168.80.77','bbsuser','admin123'); if($link) echo "wangdachu!"; else echo "fail!!" ?>
