Centos8安装LAMP

yum -y install httpd mariadb-server mariadb php php-mysql php-gd php-mbstring

iptables -F #关闭防火墙
systemctl start httpd #开机apache
systemctl enable httpd #启动apache

vim /etc/httpd/conf/httpd.conf

更改ServerName：80为localhost：80 去掉#注释

跳转行在非插入状态下输入键盘摁下跳转行数收双击gg即可完成跳转

在index.html 后输入index.php

重启apache

systemctl restart httpd

启动mysql设置密码

systemctl start mariadb

mysql -u root  发现没有密码

默认没有密码 有隐患

mysql_secure_installation

如不走安全配置设置密码

mysqladmin -u root -password ‘123456’

新建php文件测试是否正常联系

 cd var/www/html/
  vim index.php

systemctl status firewalld.service（查看防火墙状态）

然后你会发现ok了

权限优化

ps -aux | grep httpd


id apache

chown -R apache:apache /var/www/html/

yum源安装时候，出现下面错误“错误：Failed to download metadata for repo ‘AppStream’: Cannot prepare internal mirrorlist: No URLs in mirrorlist”

1、进入yum的repos目录

cd /etc/yum.repos.d/

2、修改所有的CentOS文件内容

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*

sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*3、更新yum源为阿里镜像

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

yum clean all

yum makecache4、yum安装测试是否可以yum安装

yum install wget –y

安装LAMP所需要的依赖包

yum install -y epel-release yum-utils unzip curl wget bash-completion policycoreutils-python mlocate bzip2
