02 WWW架設

(2020/11/09)

一、架設WWW伺服器

• [centos@shsps ~]$ rpm -qa |grep httpd (檢查有無httpd服務的相關程式，發現沒有安裝)

• [centos@shsps ~]$ yum -y install httpd httpd-tools (利用yum來安裝httpd及httpd-tools的套件)

  • Error: This command has to be run under the root user. (無法執行)

• [centos@shsps ~]$ sudo -s (取得root權限)

• [root@shsps centos]# yum -y install httpd httpd-tools (重新安裝就可以了)

• [root@shsps centos]# rpm -qa |grep httpd (再查一次，就有相關套件了)

  • httpd-filesystem-2.4.37-21.module_el8.2.0+494+1df74eae.noarch

  • httpd-tools-2.4.37-21.module_el8.2.0+494+1df74eae.x86_64

  • centos-logos-httpd-80.5-2.el8.noarch

  • httpd-2.4.37-21.module_el8.2.0+494+1df74eae.x86_64

  • [root@shsps centos]# systemctl start httpd.service (啟動httpd的服務，也可以寫systemctl start httpd)

• • • [root@shsps centos]# service httpd stop (以前的寫法，也會導到如上的指令)

    • Redirecting to /bin/systemctl stop httpd.service

    • [root@shsps centos]# service httpd start (以前的寫法)

    • Redirecting to /bin/systemctl start httpd.service

• [root@shsps centos]# systemctl enable httpd.service (開機就啟動httpd的服務)

• 發現仍無法瀏覽網頁

二、關閉SELinux

• • [root@shsps centos]# vi /etc/sysconfig/selinux

  • # enforcing - SELinux security policy is enforced.

  • # permissive - SELinux prints warnings instead of enforcing.

  • # disabled - No SELinux policy is loaded.

  • #SELINUX=enforcing

  • SELINUX=disabled

  • # SELINUXTYPE= can take one of these three value

  • # targeted - Targeted processes are protected,

  • # minimum - Modification of targeted policy. Only selected processes are protected.

  • # mls - Multi Level Security protection.

  • SELINUXTYPE=targeted

• 先把上面的內容，改成disabled，並且要重新啟動機器，這樣就可以關閉SELinux

• 關閉防火牆，本虛擬機好像沒有安裝firwall，所以執行如下指令時並無作用

  • [root@shsps centos]# systemctl stop firewalld.service

    • Failed to stop firewalld.service: Unit firewalld.service not loaded.

  • [root@shsps centos]# systemctl disable firewalld.service

    • Failed to disable unit: Unit file firewalld.service does not exist.

三、開啟80埠

• 到虛擬機的安全群組的規則增加一條可利用80埠進入的規則，不用重新開機

四、輸入網址

• 輸入網址，會顯示一預設網頁，代表WWW架設成功

五、WWW相關設定檔

• 待補上
