一、检查并卸载原有的 apache 软件包列表

1. 查看 httpd 软件包列表

 rpm -qa |grep httpd

2. 卸载 apache

yum install -y epel-release
yum install -y dnf
dnf remove httpd\*

3. 检测是否卸载

rpm -qa |grep httpd

二、使用 yum 安装

1. 安装

yum install -y httpd

2. 查看 80 端口是否被占用，被占用将无法启动

netstat -antlp | grep 80

3. 启动 apache 服务

systemctl start httpd

4. 客户端浏览器测试

http://182.92.150.105

三、apache rpm包安装的常用命令

systemctl start httpd                                启动
systemctl stop httpd                                 停止
systemctl restart httpd                              重启

systemctl enable httpd                               开机启动
systemctl disable httpd                              开机不启动
systemctl list-unit-files | grep httpd               检查Apache是否已经安装了开机自动启动

systemctl status httpd                               检查状态

yum remove -y httpd                                  yum 卸载httpd软件包
dnf remove httpd\*                                   卸载httpd所有软件包，包括工具包

四、rpm 包 apache 常见配置文件位置

配置文件位置: /etc/httpd/conf/httpd.conf
网页文件位置：/var/www/html/
日志文件位置：/var/log/httpd/

五、开机自启

systemctl enable httpd                               开机启动
systemctl disable httpd                              开机不启动
systemctl list-unit-files | grep httpd               检查Apache是否已经安装了开机自动启动
