LNMP architecture and forum construction and one-click deployment

data flow

1. Nginx service installation

1. Turn off the firewall

[root@king ~]# systemctl stop firewalld
[root@king ~]# systemctl disable firewalld
[root@king ~]# setenforce 0

2. Drag the required software package into the /opt directory

3. Install dependent packages

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

4. Create a running user and group

useradd -M -s /sbin/nologin nginx

5. Configure software modules

cd /opt
tar zxvf nginx-1.20.2.tar.gz
 
cd nginx-1.20.2/
./configure \    
--prefix=/usr/local/nginx \               #指定nginx的安装路径
--user=nginx \                            #指定用户名
--group=nginx \                           #指定组名
--with-http_stub_status_module            #启用 http_stub_status_module 模块以支持状态统计

6. Compile and install Nginx

make -j2 && make install

7. Optimize the configuration file path to facilitate the system to identify Nginx operation commands

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/    #让系统识别nginx的操作命令

8. Add 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

9. Empower, restart the service and set the boot to start automatically

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

10. Verification service

2. Compile and install MySQL service

1. Drag the required software package into the /opt directory

2. Install environment dependent packages

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

3. Configure software modules

tar zxf boost_1_59_0.tar.gz
tar zxf mysql-5.7.17.tar.gz
mv boost_1_59_0 /usr/local/boost

[root@king mysql-5.7.17]# vim /etc/my.cnf

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysqld]
user = mysql

7. Modify the owner and group of the mysql installation directory and configuration files

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

8. Set the path environment variable

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

9. Initialize the database

cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \				#生成初始化密码为空
--user=mysql \                      #指定管理用户
--basedir=/usr/local/mysql \        #指定数据库的安装目录
--datadir=/usr/local/mysql/data		#指定数据库文件的存储路径

10. Add mysqld system service

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/		#用于systemctl服务管理
systemctl daemon-reload         #刷新识别     
systemctl start mysqld.service  #开启服务
systemctl enable mysqld         #开机自启动
netstat -anpt | grep 3306       #查看端口

11. Modify the login password of mysql

mysqladmin -u root -p password "123456"

12. Authorize remote login, then quit to exit

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by '123456';
#授予root用户可以在所有终端远程登录，使用的密码是123456，并对所有数据库和所有表有操作权限
 
show databases;			#查看当前已有的数据库

3. Compile and install php service

--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \

cp /opt/php-7.1.24/php.ini-development /usr/local/php/lib/php.ini
vim /usr/local/php/lib/php.ini

--939行--取消注释，修改时区
date.timezone = Asia/Shanghai

--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock

6. Optimize the PHP executable program file into the path environment variable directory for system identification

ln -s /usr/local/php/bin/* /usr/local/bin/
php -m 			#查看PHP 加载了哪些模块

7. Process service configuration file php-fpm.conf

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

vim /usr/local/php/etc/php-fpm.conf

17行取消注释 pid = run/php-fpm.pid

8. Extended configuration file www.conf

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

9. Start php-fpm

ln -s /usr/local/php/sbin/* /usr/local/sbin
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000

10. Modify the configuration file of the nginx service to allow nginx to support PHP

vim /usr/local/nginx/conf/nginx.conf
--45行，添加index.php
location / {
              root   html;
              index  index.html index.htm index.php;
          }
--65行到71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
   #fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;  #$document_root 代表当前请求在root指令中指定的值
	include        fastcgi_params;
}

systemctl restart nginx.service

11. Verify PHP test page

[root@king php-fpm.d]# vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>

4. Deploy the Discuz community forum

1. Create a database

mysql -u root -p
mysql> CREATE DATABASE bbs;
#把bbs数据库里面所有表的权限授予给bbsuser，并设置密码
mysql> GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY '123456'；
#刷新数据库
mysql>flush privileges;

2. Drag the software package required by the forum into the /opt directory and decompress it

unzip Discuz_X3.4_SC_UTF8.zip -d /opt/dis

3. Upload the site update package

cd dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs

4. Change the owner of the wheeled directory

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

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

5. Visit the forum page and install the Discuz forum

论坛页面访问
http://192.168.109.12/bbs/install/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：123456
管理员账号:admin
管理员密码:123456

6. Test whether new users can be registered

访问论坛页面：
http://192.168.109.12/bbs/index.php
http://192.168.109.12/bbs/admin.php

5. One-click deployment of LNMP scripts

#!/bin/bash
#关闭系统防火墙和安全机制
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
