圖解lamp架構

關於linux防火牆

cat /etc/selinux/config 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted


執行中
#     enforcing - SELinux security policy is enforced.
臨時關閉中，下次開機還會啟動
#     permissive - SELinux prints warnings instead of enforcing.
永久關閉了
#     disabled - No SELinux policy is loaded.

修改selinux狀態，enforcing > permissive
setenforce 0

想永久關閉，還得修改配置檔案，然後reboot
reboot



關閉firewalld防火牆
iptables -F     清空iptables規則

systemctl stop firewalld     停止防火牆執行
systemctl disable firewalld   禁止防火牆開機自啟
以上兩條命令敲完就相當於永久禁用firewalld
 

通過yum命令點點點搭建lamp架構

安裝準備其執行環境
[root@xinxin ~]# yum install httpd  -y            安裝apache

[root@xinxin ~]#yum install  php  -y              安裝php後端語言

[root@xinxin ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm 

[root@xinxin ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm           下載資料庫yum源配置檔案

[root@xinxin yum，repos.d]# rpm -ivh mysql-community-release-el7-5.noarch.rpm   獲取該repo檔案

[root@xinxin yum，repos.d]# yum -y install mysql-community-server              安裝資料庫

[root@xinxin yum，repos.d]# systemctl restart mysqld              啟動資料庫

[root@xinxin yum，repos.d]# mysql_secure_installation                初始化資料庫密碼

[root@xinxin yum，repos.d]# mysql -uroot -p                  用新密碼登入資料庫

[root@xinxin ~]# wget https://www.dismall.com/forum.php?mod=attachment&aid=MTA0fGZlYmVhN2ZlfDE2NDg3ODQ3ODV8MHw3Mw%3D%3D    下載該
論壇原始碼

[root@xinxin ~]# unzip -d   /var/www/html/   Discuz_X3.4_SC_UTF8_20220131.zip          通過該命令將其解壓到指定目錄下

[root@xinxin ~]# cd /var/www/html/                   進入到該目錄下

[root@xinxin html]# mv upload/*   ./                將該檔案內的所有內容全部移到當前目錄下才能訪問到該網頁

[root@xinxin html]# chmod -R 777 ./*                 需要對這些檔案提權才能讀取到這些檔案內容

[root@xinxin html]# systemctl restart httpd          重啟Apache服務即可通過自己的ip進入到網頁中操作

[root@xinxin html]# yum install php-mysqli -y        安裝過程中發現少一個驅動，通過此命令安裝該驅動

最終安裝完成介面
