测试nginx是否正常
systemctl restart nginx.service 
安装以下软件包
解压mysql软件包
tar -xf mysql-8.0.30-el7-x86_64.tar.gz 重命名文件
mv mysql-8.0.30-el7-x86_64.tar.gz mysql
将mysql移动到/usr/local
mv mysql /usr/local创建mysql程序用户
useradd -s /sbin/nologin mysql修改所有者和所在组
chown mysql.mysql -R /usr/local/mysql/
在etc目录下添加mysql的主配置文件
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 = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION修改配置文件所有者和所在组
chown mysql.mysql /etc/my.cnf 让系统能够识别mysql命令
echo "PATH+$PATH:/usr/local/mysql/bin" >> /etc/profile
source /etc/profile建立数据库
cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
cd /usr/local/mysql/support-files/
cp mysql.server /etc/init.d/mysqld 赋权并重启
chmod +x /etc/init.d/mysqld
systemctl daemon-reload
systemctl restart mysqld检查端口是否开启
创建数据库密码
配置数据库
create user 'root'@'%' identified by '123456';
CREATE DATABASE bbs;
CREATE USER 'bbsuser'@'%' IDENTIFIED BY 'admin123';
GRANT ALL PRIVILEGES ON bbs.* TO 'bbsuser'@'%';
FLUSH PRIVILEGES;
CREATE USER 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
GRANT ALL PRIVILEGES ON bbs.* TO 'bbsuser'@'localhost';
FLUSH PRIVILEGES;安装php
tar -xf php-8.1.27
apt-get install -y libgd-dev libjpeg8-dev libpng-dev libfreetype6-dev libxml2-dev zlib1g-dev libcurl4-openssl-dev libssl-dev libonig-dev libsqlite3-dev
groupadd nobody
make -j 4 && make install
cd /opt/php-8.1.27/

ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/
cp php.ini-development /usr/local/php/lib/php.ini修改配置
cd /usr/local/php/lib
vim php.ini 
修改进程服务端的配置文件
cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
扩展配置文件
cd /usr/local/php/etc/php-fpm.d
cp www.conf.default www.conf启动php端口服务
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini 检查端口是否启用
cd /opt/php-8.1.27/sapi/fpm/
复制系统管理文件到/usr/lib/systemd/system/目录下，让系统识别
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service 启动服务
systemctl restart php-fpm.service 查看日志检查是否成功启动
显示"只读"报错，则更换主配置文件路径
配置nginx
cd /usr/local/nginx/conf在修改重要配置文件前建议先备份
解压Discuz
unzip Discuz_X3.5_SC_UTF8.zip -d /opt/dis同样复制并赋权
如显示不可写更改文件目录即可
