LNMP architecture deployment (attached: deployment of Discuz community forum web application)

---

Preface

• The "A" in LAMP corresponds to the Web server software Apache HTTP server
• With the increasing use of Nginx in enterprises, the LNMP architecture is also favored by more and more Linux system engineers. The "N" corresponds to the Nginx service
• Just like building the LAMP platform, building the LNMP platform also requires a Linux server, MySQL database and PHP parsing environment. The difference is mainly in the cooperative configuration of Nginx and PHP
• The environment of this article is based on CentOS 7, and the local YUM source warehouse has been installed

One, install Nginx service

Here I have mentioned in my previous article, I only post the code of the relevant configuration steps here, without repeating it.
Portal ( there is a software package download link in the article ):
LAMP
Nginx

systemctl stop firewalld.service
systemctl disable firewalld.service 
setenforce 0

yum remove -y httpd
#之前若安装过，这里必须先卸载，会有冲突，本文使用源码编译安装

1. Install dependencies

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

2. Create a running user

useradd -M -s /sbin/nologin nginx

3. Compile and install

cd /opt
tar zxvf nginx-1.12.0.tar.gz

cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module

make -j 2
make install

4. Optimization path

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

5. Add Nginx system service

vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target
[Service]
Type=£orking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecrReload=/bin/kill -s HUP $MAINPID
ExecrStop=/bin/ki11 -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

---

Two, install MySQL service

1. Install MySQL environment dependency package

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

2. Create a running user

useradd -M -s /sbin/nologin mysql

3. Compile and install

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

cd 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

4. Modify the mysql configuration file

vim /etc/my.cnf
#删除原配置项，再重新添加下面内容

[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 the owner group of the mysql installation directory and configuration file

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

6. Set path environment variable

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

7. Initialize the database

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

8. Add mysql 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

netstat -anpt | grep 3306

9. Modify mysql login password

mysqladmin -u root -p password "123123" 	

10. Authorize remote login

mysql -u root -p

grant all privileges on *.* to 'root'@'%' identified by '123123';

show databases;

quit

---

Three, install and configure PHP parsing environment

1. Installation environment dependent packages

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. Compile and install

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 -j 4 && make install

3. Path optimization

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

4. Adjust the PHP configuration file

php has three configuration files:
php.ini-main configuration file
php-fpm.conf-process service configuration file
www.conf-extended configuration file

#调整主配置文件：
cp /opt/php-7.1.10/php.ini-development /usr/local/php/php.ini	
vim /usr/local/php/php.ini
--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释，修改
date.timezone = Asia/Shanghai

php -m
#验证安装的模块

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

vim php-fpm.conf
--17行--去掉";"注释
pid = run/php-fpm.pid

调整扩展配置文件：
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

#优化
vim www.conf

user = nginx
#更改用户名
group = nginx

pm.max_children = 50
#fpm支持的最大进程数
pm.start_servers = 20
#启动时开启的进程数
pm.min_spare_servers = 5
#空闲时最小保留的进程数
pm.max_spare_servers = 20
#最大空闲进程数

5. Start php-fpm

/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini

netstat -anpt | grep 9000
#PHP-FPM(FastCGI Process Manager：FastCGI 进程管理器)是一个 PHPFastCGI 管理器， 由于 Nginx 服务器不能处理动态页面，需要由 Nginx 把动态请求交给 php-fpm 进程进行解析

6. Configure Nginx to support PHP parsing

vim /usr/local/nginx/conf/nginx.conf

--65行--取消注释，修改
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;	#将/scripts修改为nginx的工作目录
	include        fastcgi_params;
}

systemctl restart nginx.service

7. Verify PHP test page

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

<?php
phpinfo();
?>


nginx
#检测一下
killall -3 nginx
nginx
#若有问题，终止进程后重新启动

浏览器访问
http://192.168.126.15/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;

quit


vim /usr/local/nginx/html/index.php
#替换原来的测试页内容

<?php
$link=mysqli_connect('192.168.126.15','bbsuser','admin123');
if($link) echo "<h1>Success~</h1>";
else echo "Fail~";
?>

浏览器访问
http://192.168.126.15/index.php

Fourth, deploy Discuz community forum web application

cd /opt
unzip Discuz_X3.4_SC_UTF8.zip -d /opt/dis
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/

调整论坛目录的权限:
cd /usr/local/nginx/html/bbs/
chown -R root:nginx ./config/
chown -R root:nginx ./data/
chown -R root:nginx ./uc_client/
chown -R root:nginx ./uc_server/

chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/


论坛页面访问：
http://192.168.126.15/bbs/install/index.php

http://192.168.126.15/bbs/index.php


数据库服务器: localhost
###本地架设就用localhost,如何不是在在本机上就要填写IP地址和端口号
数据库名字: bbs
数据库用户名: bbsuser
数据库密码: admin123
管理员账号:admin
管理员密码:admin123
