• 查看Apache的版本

##  httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Aug  8 2019 11:41:18

• Apache命令

systemctl stop httpd   停止Apache服务

systemctl start httpd  启动Apache服务

systemctl restart httpd  重启Apache服务

systemctl disable httpd  禁用Apache开机自启动

systemctl enable httpd  Apache开机自启动

systemctl reload httpd  更改配置后重新加载Apache服务

ubuntu版本安装apache2

• 安装apache2

sudo apt-get install apache2

• 手动启动使用(默认安装完成后是启动的)

sudo /etc/init.d/apache2 start

• 测试安装成功

ps -ef | grep httpd 

• 重启服务器

sudo /etc/init.d/apache2 restart

下载完成后需要打开安全组设置开放80端口

apache2的部署目录 /var/www/html
如果当前用户没有权限操作/var/www/html
使用sudo临时提升权限，将 /var/www/html的权限设置成777，原先是755。设置了之后，ubuntu用户就可以往html目录中放置文件或文件夹了
sudo chmod -R 777 /var/www/html
编写一个网页使用fileZilla部署到apache上，远程访问
