centos7安装lamp

配置前的准备：

禁掉selinux，修改/etc/sysconfig/selinux中的SELINUX为SELINUX=disabled

一. 安装Apache

[root@localhost ~]# yum -y install httpd
[root@localhost ~]# systemctl start httpd.service #开启Apache服务
[root@localhost ~]# systemctl status httpd.service  #查看Apache状态
[root@localhost ~]# systemctl enable httpd.service   #开机自启动
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@localhost ~]#  

#测试语法

[root@localhost ~]# apachectl configtest 
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK

#放行80端口

[root@localhost ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success

#重启防火墙以让更改立刻生效

[root@localhost ~]# firewall-cmd --reload
success

#检查配置是否成功

[root@localhost ~]# firewall-cmd --list-all 
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  sources: 
  services: dhcpv6-client ssh
  ports: 80/tcp
  protocols: 
  masquerade: no
  forward-ports: 
  sourceports: 
  icmp-blocks: 
  rich rules: 

二、安装MariaDB

[root@localhost ~]# yum install mariadb mariadb-server #询问是否要安装，输入Y即可自动安装,直到安装完成
[root@localhost ~]# systemctl start mariadb.service #启动MariaDB
[root@localhost ~]# systemctl enable mariadb.service ##设置开机自启动
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

其他操作：

systemctl stop mariadb.service #停止MariaDB

systemctl restart mariadb.service #重启MariaDB

备份配置文件：

[root@localhost ~]# mv /etc/my.cnf{,.bak}

[root@localhost ~]# cp /usr/share/mysql/my-huge.cnf /etc/my.cnf #拷贝配置文件

为root账户设置密码

[root@localhost ~]# mysql_secure_installation

#重启MariaDB

[root@localhost ~]# systemctl restart mariadb.service

三、安装PHP

[root@localhost ~]# yum install php -y

安装PHP组件，使PHP支持 MariaDB

[root@localhost ~]# yum install php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash -y

#重启MariaDB

[root@localhost ~]# systemctl restart mariadb.service

 #重启apache

[root@localhost ~]# systemctl restart httpd.service

测试

[root@localhost ~]# cd /var/www/html
[root@localhost html]# vim index.php
<?php
phpinfo();
?>

 在客户端浏览器输入服务器IP地址，可以看到如下图所示相关的配置信息！
