  • 查看Apache的版本

[root@iZ1i4qd6oynml0Z ~]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Aug  8 2019 11:41:18

  • 验证安装

用浏览器打开服务器的IP地址，将看到默认的Apache欢迎页面表示成功

  • Apache命令

停止Apache服务

systemctl stop httpd

启动Apache服务

systemctl start httpd

重启Apache服务

systemctl restart httpd

禁用Apache开机自启动

systemctl disable httpd

Apache开机自启动

systemctl enable httpd

更改配置后重新加载Apache服务

systemctl reload httpd

Apache的主配置文件：/etc/httpd/conf/httpd.conf

安装完后就可以到Apache的默认目录/var/www/html 添加一个简单的index.html

<!DOCTYPE html>
<head>
        <title>test</title>
</head>
<body>
        <p>Hello World!</p>
</body>
</html>

再次在浏览器输入ip地址就会显示以下界面
