LNMP represents the web server architecture of Nginx+MySQL+PHP under Linux system.
Linux is a kind of Unix computer operating system, which is the most popular free operating system. Representative versions include debian, centos, ubuntu, fedora, gentoo, etc.
Nginx is a high-performance HTTP and reverse proxy server, and also an IMAP/POP3/SMTP proxy server.
Mysql is a small relational database management system.
PHP is a script language that embeds HTML documents on the server side.
These four kinds of software are free and open-source software, which are combined to become a free, efficient and extensible website service system
In this chapter, I will take you to compile LNMP manually.
There are four steps in the experiment
Install nginx service
Install mysql service
Install and configure PHP parsing environment

Experimental environment: centos7.5 ﹣ nginx-1.12 ﹣ mysql-boot-5.7 ﹣ php-7.1
Experiment begins
[install nginx service]
1. Installation environment depends on installation package:
[root@localhost ~]# yum -y install pcre-devel zlib-devel gcc gcc-c++
2. Create running users and groups
[root@localhost ~]# useradd -M -s /sbin/nologin nginx
3. Unzip the installation package
tar zxvf nginx-1.12.2.tar.gz -C /opt/
4. Compilation, installation and configuration optimization
cd nginx-1.12.2/ ./configure \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_stub_status_module make && make install //Compile and install nginx ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ //Creating a soft connection for a command systemctl stop firewalld.service //Turn off firewall setenforce 0 nginx -t //Check the configuration file for problems //Convenient to manage nginx service, edit nginx service script and add it to system CTL 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 ExecReload=/usr/bin/kill -s HUP $MAINPID ExecStop=/usr/bin/ki11 -s QUIT $MATNPID PrivateTmp=true [Install] WantedBy=multi-user.target chmod 754 nginx.service //Give execution permission
[install mysql service]
1. Install compilation tools
yum -y install \ ncurses \ ncurses-devel \ bison \ cmake\ make
2. Decompress the package
tar zxvf mysql-boost-5.7.20.tar.gz -C /opt
3. Customized configuration
cd /opt/my cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ -DSYSCONFDIR=/etc \ -DSYSTEMD_PID_DIR=/usr/local/mysql \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DWITH_BOOST=boost \ -DWITH_SYSTEMD=1 //This parameter must be added in version 5.7
4. Compile and install
make && make install
5. Add program user and relevant permission settings
useradd -s /sbin/nologin mysql chown -R mysql:mysql /usr/local/mysql/ //Set the main genus group
6. Modify the configuration file (delete the original content and copy the following content)
vi /etc/my.cnf
[client] port = 3306 default-character-set=utf8 socket = /usr/local/mysql/mysql.sock [mysql] port = 3306 default-character-set=utf8 socket = /usr/local/mysql/mysql.sock [mysqld] user = mysql basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 character_set_server=utf8 pid-file = /usr/local/mysql/mysqld.pid socket = /usr/local/mysql/mysql.sock server-id = 1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
7. Setting environment variables
echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile echo 'export PATH' >> /etc/profile source /etc/profile
8. Initialize database
cd /usr/local/mysql/ bin/mysqld \ --initialize-insecure \ --user=mysql \ --basedir=/usr/local/mysql \ --datadir=/usr/local/mysql/data cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
9. Start, close and status of database
systemctl enable mysqld systemctl start mysqld systemctl stop mysqld netstat -natp | grep 3306
10. Set password
mysqladmin -uroot -p password mysql -u root -p //Enter database
[install PHP service]
1. Installation environment dependency package
yum install -y \ libjpeg \ libjpeg-devel \ libpng libpng-devel \ freetype freetype-devel \ libxml2 \ libxml2-devel \ zlib zlib-devel \ curl curl-devel \ openssl openssl-devel
2. Unzip the installation package
tar jxvf php-7.1.10.tar.bz -C /opt
3. Customized configuration
cd /opt/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
4. Modify the configuration file
//php has three configuration files:
php.ini / / core profile
php-fpm.conf / / process service configuration file
www.conf / / extended profile
cp php.ini-development /usr/local/php/lib/php.ini //Configure core modules vim /usr/local/php/lib/php.ini mysqli.default_socket = /usr/local/mysql/mysql.sock date.timezone = Asia/Shanghai //Set path, timely area /usr/local/php/bin/php -m //Verify installation module
Configure and optimize fpm module
cd /usr/local/php/etc/ cp php-fpm.conf.default php-fpm.conf vim php-fpm.conf pid = run/php-fpm.pid //Remove; note pid on cd /usr/local/php/etc/php-fpm.d/ cp www.conf.default www.conf /usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini //Open PHP FPM module netstat -natp | grep 9000 ln -s /usr/local/php/bin/* /usr/local/bin/ //Create a soft connection. System identification command ln -s /usr/local/php/bin/* /usr/local/bin/ //Create a soft connection. System identification command
Make nginx support php function
vim /usr/local/nginx/conf/nginx.conf //There is in the configuration file, just remove the comment and modify the path
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;
include fastcgi_params;
}5. Configure service home page information
killall -1 nginx //Restart nginx service cd /usr/local/nginx/html/ mv index.html index.php vim index.php <?php phpinfo(); ?> //Original content change 192.168.109.137/index.php //Access home page
6. Test whether the database works normally
mysql -uroot -p CREATE DATABASE bbs; GRANT all ON bbs.* TO 'bbsuser' @'%' IDENTIFIED BY 'admin123'; GRANT all ON bbs.* TO 'bbsuser' @'localhost' IDENTIFIED BY 'admin123'; flush privileges; #Enter / / configure account file show databases; /view the database
7. Test connectivity
vi /usr/local/nginx/html/index. php
##The content of the original test page is changed as follows
<?php
$link=mysqli_connect('192.168.109.137',' bbsadm' ,'admin123') ;
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!" ;
?>
systemctl restart nginx
//Test "http://192.168.109.137/index.php" on the web page“
