centos 7.0系统安装配置图解教程</p>
<p>
</p>
<p>
<strong>一、配置防火墙，开启80端口、3306端口</strong></p>
<p>
centos 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。</p>
<p>
<strong>1、关闭firewall：</strong></p>
<p>
systemctl stop firewalld.service #停止firewall<br>
systemctl disable firewalld.service #禁止firewall开机启动</p>
<p>
<strong>2、安装iptables防火墙</strong></p>

<p>
mysql_secure_installation<br>
回车，根据提示输入y<br>
输入2次密码，回车<br>
根据提示一路输入y<br>
最后出现：thanks for using mysql!<br>
mariadb密码设置完成，重新启动 mariadb：<br>
systemctl restart mariadb.service #重启mariadb</p>
<p>
<strong>三、安装php</strong></p>
<p>
1、安装php</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS 7.0服务器安装配置LAMP服务器(Apache+PHP+MariaDB)" alt="CentOS 7.0服务器安装配置LAMP服务器(Apache+PHP+MariaDB)" height="386" src="https://zhuji.jb51.net/uploads/img/202305/5c01ca21a3f60fa435ca899a2594f87e.jpg" width="640"></p>
<p>
yum install php #根据提示输入y直到安装完成</p>
<p>
2、安装php组件，使php支持 mariadb</p>
<p>
yum install php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash</p>
<p>
#这里选择以上安装包进行安装，根据提示输入y回车</p>
<p>
systemctl restart mariadb.service #重启mariadb</p>
