一、实验任务及目的

了解下载Typecho源码，通过Web界面完成博客安装

二、实验内容

[root@localhost ~]# chmod 644 /etc/httpd/conf.modules.d/00-mpm.conf
[root@localhost ~]# chown root:root /etc/httpd/conf.modules.d/00-mpm.conf
[root@localhost ~]# httpd -t
Syntax OK
[root@localhost ~]# systemctl restart httpd
[root@localhost ~]# httpd -V | grep -i mpm
Server MPM:     prefork

主配置⽂件 httpd.conf

[root@localhost ~]# httpd -M |grep dir
 dir_module (shared)
 userdir_module (shared)
[root@localhost ~]# vim /etc/httpd/conf/httpd.conf
[root@localhost ~]#  mkdir -p /data/html

LAMP架构部署

安装Apache

yum install -y httpd 
systemctl enable --now httpd
systemctl stop firewalld
setenforce 0

安装php

yum install -y php* 
systemctl enable --now php-fpm 
systemctl status php-fpm 
systemctl restart httpd

安装MySQL

yum install -y mariadb-server mariadb
 systemctl enable --now mariadb 
 mysqladmin password '123456' 
 mysql -uroot -p123456 -e "show databases;"

PHP探针测试

<?php 
    phpinfo(); 
?>

数据库连接测试

<?php 
$servername = "localhost"; 
$username = "root"; 
$password = "123456"; 

$conn = mysqli_connect($servername, $username, $password); 
 
if (!$conn) { 
         die("Connection failed: " . mysqli_connect_error()); 
    }
    
    echo "连接MySQL...成功！"; 
?> 

安装phpmyadmin

cd /var/www/html 
wget https://files.phpmyadmin.net/phpMyAdmin/5.1.1/phpMyAdmin-5.1.1-all-languages.zip
unzip phpMyAdmin-5.1.1-all-languages.zip 
mv phpMyAdmin-5.1.1-all-languages phpmyadmin

部署typecho个⼈博客

cd /var/www/html
mkdir typecho 
cd typecho 
wget https://github.com/typecho/typecho/releases/latest/download/typecho.zip 
unzip typecho.zip

三、实验总结

重新用本地数据库部署一遍个人博客，感觉还是怪有意思的，之前用centos和阿里云的服务器部署过一遍，网址贴在这里 zidayo.cn，这个typecho的主题也同样炫酷，哈哈哈。不错不错。至于问题倒是没有遇到，教程还是很详细的！!
