• 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服務

systemctl start httpd  啟動Apache服務

systemctl restart httpd  重啟Apache服務

systemctl disable httpd  禁用Apache開機自啟動

systemctl enable httpd  Apache開機自啟動

systemctl reload httpd  更改配置后重新加載Apache服務

ubuntu版本安裝apache2

• 安裝apache2

sudo apt-get install apache2

• 手動啟動使用(默認安裝完成后是啟動的)

sudo /etc/init.d/apache2 start

• 測試安裝成功

ps -ef | grep httpd 

• 重啟服務器

sudo /etc/init.d/apache2 restart

下載完成后需要打開安全組設置開放80端口

apache2的部署目錄 /var/www/html
如果當前用戶沒有權限操作/var/www/html
使用sudo臨時提升權限，將 /var/www/html的權限設置成777，原先是755。設置了之后，ubuntu用戶就可以往html目錄中放置文件或文件夾了
sudo chmod -R 777 /var/www/html
編寫一個網頁使用fileZilla部署到apache上，遠程訪問
