阿里云centos7.6原生根目錄
兩項工作
- 打開80端口（iptables/firewalld/ali云安全組）
- 安裝apache
Part ONE 打開80端口
一、用iptables打開80端口
1、安裝iptables：
//（阿里云centos7 默認 是使用的firewall，所以要使用iptables需先安裝）
yum install iptables-services
2、把端口加入到iptables中（加入之前梢灭，可使用iptables -L -n查看端口情況）
vim /etc/sysconfig/iptables
添加：
---vim iptables---
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
:wq
3、重啟iptables：
systemctl restart iptables.service
（重啟后蒸其，使用 iptables -L -n查看）
二敏释、centos7.x用firewall打開80端口
- filrwall開啟相關命令：
// filrwall是否開啟：
# systemctl status firewalld
// 啟動：
#systemctl start firewalld
//關閉：
# systemctl stop firewalld
//開機禁用 ：
#systemctl disable firewalld
//開機啟用 ：
#systemctl enable firewalld
2.查看防火墻是否開啟的狀態(tài)，以及開放端口的情況
#systemctl status firewalld.service
//如果沒有開啟firewalld
#systemctl enable firewalld
#firewall-cmd --list-all
- 通過以下命令開放http 80 端口
//添加80端口
# firewall-cmd --zone=public --add-port=80/tcp --permanent
命令末尾的--permanent表示用久有效摸袁，不加這句的話重啟后剛才開放的端口就又失效了
4 .然后重啟防火墻
//重載
# firewall-cmd --reload
- 再次查看端口的開放情況：
//
# firewall-cmd --list-all
ports：里出現(xiàn)了 80 端口
public
target: default
icmp-block-inversion: no
interfaces:
sources:
services: dhcpv6-client ssh
ports: 80/tcp
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
三 钥顽、在阿里云控制臺上， 添加安全組規(guī)則
- path:
云服務器ECS -> 安全組 -> 安全組規(guī)則 -> 入方向 -> 添加安全組規(guī)則
- 填寫必須的選項
*端口范圍：80/80
*授權對象：0.0.0.0/0
確定靠汁。OK～
Part Two Apache安裝
一蜂大、Apache安裝
1.確保服務器系統(tǒng)處于最新狀態(tài)
yum -y update
2.重啟服務器
reboot
3.首先檢查80端口是否已經(jīng)開啟
netstat -an | grep 80
詳見 Part One
如果顯示以下內容說明已經(jīng)開啟80端口
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
tcp 0 0 172.16.134.203:56088 100.100.30.25:80 ESTABLISHED
unix 3 [ ] STREAM CONNECTED 11809
unix 2 [ ] DGRAM 11800
4.安裝Apache，并且安裝擴展模塊
yum -y install httpd httpd-manual httpd-devel mod_ssl mod_perl mod_auth_mysql
5.設置CentOS開機自動啟動Apache服務
systemctl enable httpd.service
6.檢查Apache是否已經(jīng)安裝了開機自動啟動
systemctl list-unit-files | grep httpd
如果顯示以下內容說明已經(jīng)完成自動啟動安裝
httpd.service enabled
7.啟動Apache服務
systemctl start httpd.service
8.判斷是否安裝成功Apache服務
curl http://127.0.0.1
命令行界面正常顯示一堆html蝶怔、css代碼奶浦，沒有亂碼，一般是成功了
