yum 安装 LNMP

本文主要是介绍yum 安装 LNMP，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、安装 nginx

vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1


yum install nginx -y 
nginx -v

systemctl start nginx
systemctl enable nginx

二、安装 mysql 5.7 (mariadb)

yum remove mariadb*

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server

systemctl start mysqld.service
systemctl enable mysqld.service

grep "password" /var/log/mysqld.log			#在日志文件中找出root用户的初始密码
2021-07-31T07:55:00.366359Z 1 [Note] A temporary password is generated for root@localhost: ga7%<d<0*jD&

//登录 mysql
mysql -u root -p
Enter password: 		#输入初始密码 ga7%<d<0*jD&

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Admin@123';     #密码设置要求有 大小写字母、数字和符号 组合

grant all privileges on *.* to root@"%" identified by "Admin@123" with grant option;
flush privileges;

yum -y remove mysql57-community-release-el7-10.noarch     #为了防止每次yum操作都会自动更新，卸载这个软件

三、安装 php7.2

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm 
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache php72w-redis


systemctl start php-fpm
systemctl enable php-fpm
php -v


//配置 nginx 支持 PHP 解析
cd /etc/nginx/conf.d
vim default.conf
......
    location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;  #将 /scripts 修改为nginx的工作目录
        include        fastcgi_params;
    }


cd /usr/share/nginx/html
vim index.php
<?php
phpinfo();
?>

浏览器访问：http://192.168.229.90/index.php


//测试mysql是否能连接成功
vim /usr/share/nginx/html/index.php
<?php
$link=mysqli_connect('192.168.229.90','root','Admin@123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

浏览器访问：http://192.168.229.90/index.php
