一、LNMP是什么
Linux+Nginx+MySQL+PHP
二、实际步骤
1.启用虚拟机
1.1 启动三台虚拟机分别命名为nginx，mysql，php
1.2 分别配置基础环境
关掉防火墙
关掉selinux
关掉网络图形化工具
1.3 测试外网连通性
2.更新源
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
3.安装nginx并配置
3.1 下载nginx源码包并安装
curl -O https://nginx.org/download/nginx-1.21.6.tar.gz
tar zxf nginx-1.21.6.tar.gz
cd nginx-1.21.6/
./configure --prefix=/usr/local/nginx && make && make install
注：若有依赖缺失，按照提示安装即可
3.2 配置nginx
vim /usr/local/nginx/conf/nginx.conf
cd /usr/local/nginx/
sbin/nginx
4.安装mysql并配置
4.1 安装mysql
yum install -y mysql
wget https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
rpm -ivh mysql57-community-release-el7-8.noarch.rpm
yum -y install mysql-server
4.2 更改root用户密码并启用远程登录
systemctl restart mysqld
grep 'temporary password' /var/log/mysqld.log
mysql -uroot -poSXoXa+4,/p,
alter user user() identified by "1234.Com";
drop user 'root'@'localhost';
create user 'root'@'%' identified by '1234.Com'
5.安装php并配置
5.1 安装新版本 PHP
yum install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml php72w-ldap php72w-mcrypt
查看版本php -v
5.2 配置php
vim /etc/php-fpm.d/www.conf
mkdir /usr/local/nginx/html -p
vim /usr/local/nginx/html/index.php
systemctl start php-fpm
6.连通测试
三、结果验证
1.解压并放置应用discuz
1.1 于php主机上解压应用源码包
mv Discuz_X3.5_SC_UTF8_20230726.zip /opt
cd /opt
unzip Discuz_X3.5_SC_UTF8_20230726.zip
rm -f /usr/local/nginx/html/index.php
mv upload/* /usr/local/nginx/html/
chown -R apache /usr/local/nginx/html/*
1.2 nginx主机上解压应用源码包
mv Discuz_X3.5_SC_UTF8_20230726.zip /opt
cd /opt
unzip Discuz_X3.5_SC_UTF8_20230726.zip
rm -f /usr/local/nginx/html/index.php
mv upload/* /usr/local/nginx/html/
useradd -s /sbin/nologin nginx -M
chown -R nginx /usr/local/nginx/html/*
2.登录discuz页面完成安装
