1. 安装PHP8

  更新系统：

yum update

  安装EPEL存储库：

yum install epel-release

  安装Remi存储库（提供了最新的 PHP 版本）：

yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

  启用Remi存储库中的PHP8：

yum install yum-utils
yum-config-manager --enable remi-php80

  安装PHP 8和相关扩展：

yum install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mbstring php-curl php-xml php-pear php-bcmath php-json

  验证PHP安装：

php -v
PHP 8.0.29 (cli) (built: Jun  7 2023 17:25:45) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.29, Copyright (c) Zend Technologies

  配置和启动PHP-FPM：

systemctl enable php-fpm
systemctl start php-fpm

ss -tnlp | grep 9000
LISTEN     0      128    127.0.0.1:9000                     *:*                   users:(("php-fpm",pid=913,fd=9),("php-fpm",pid=912,fd=9),("php-fpm",pid=911,fd=9),("php-fpm",pid=910,fd=9),("php-fpm",pid=909,fd=9),("php-fpm",pid=908,fd=7))

2. 安装MySQL8

  安装编译所需的依赖项：

yum install -y gcc-c++ openssl  openssl-devel make bison ncurses-devel
yum install centos-release-scl
yum install devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils

  编译安装cmake3.25.3

tar xvf cmake-3.25.3.tar.gz 
cd cmake-3.25.3
./bootstrap 
make && make install 

/usr/local/bin/cmake --version
cmake version 3.25.3

ln -s /usr/local/bin/cmake /usr/bin/
cmake --version
cmake version 3.25.3

  解压并编译源代码包：

wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.33.tar.gz

tar xvf mysql-8.0.33.tar.gz
cd mysql-8.0.33

mkdir build
cd build/

  运行CMake生成Makefile：

cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/var/lib/mysql \
-DWITH_INNODB_MEMCACHED=ON \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/usr/local/boost

make && make install

  将MySQL安装到 /usr/local/mysql目录，数据目录为 /var/lib/mysql，启用InnoDB Memcached插件，启用 MyISAM 存储引擎，并指定Boost库的路径

  配置MySQL：

groupadd mysql
useradd -r -g mysql -s /bin/false mysql
cd /usr/local/mysql
chown -R mysql:mysql .
bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/var/lib/mysql

  设置MySQL开机自启动：

cp support-files/mysql.server /etc/init.d/mysql
chkconfig --add mysql
chkconfig mysql on

cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
log-error=/var/lib/mysql/mysql.log
pid-file=/var/lib/mysql/mysql.pid
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/lib/mysql/mysql.log
pid-file=/var/lib/mysql/mysql.pid
socket=/tmp/mysql.sock
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

  启动MySQL服务：

systemctl restart mysql
systemctl status mysql

  进行安全性配置：

/usr/local/mysql/bin/mysql_secure_installation

ln -s /usr/local/mysql/bin/mysql /usr/bin/

mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql> 
mysql> update user set host = '%' where user = 'root';
mysql> flush privileges;

3. 配置Nginx1.22

  Nginx1.22的安装与配置可参考我的其他博客文章

/usr/local/nginx/sbin/nginx -v
nginx version: nginx/1.22.0

   location / {
        root   html;
        index  index.php index.html index.htm;
    }
   
           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;
        }

  /usr/local/nginx/html为网站发布目录，我的为/usr/local/nginx/html

cat /usr/local/nginx/html/index.php 
<?php  
  echo phpinfo();  
?>

4. 安装Discuz! X3.5

  Discuz! X3.5官网站点

unzip Discuz_X3.5_SC_UTF8_20230520.zip

  解压缩得到如下三个文件：
  upload这个目录下面的所有文件是我们需要上传到服务器上的可用程序文件
  readme目录为产品介绍、授权、安装、升级、转换以及版本更新日志说明
  utility目录为论坛附带工具，包括升级程序

  将upload这个目录下的所有文件上传到/usr/local/nginx/html目录

cp -r ./upload/* /usr/local/nginx/html/

cd /usr/local/nginx/html/
chmod 757  -R  data/  uc_server/  config/  uc_client/
