[Centos7] 安裝apache+php7+mariadb10+selinux @新精讚

OS

CentOS Linux release 7.3.1611 (Core)

安裝apache

# yum install httpd

開啟防火牆 Selinux

# firewall-cmd --zone=public --add-port=80/tcp --permanent

# firewall-cmd --reload

開啟SELINUX

# setsebool httpd_can_network_connect on

# setsebool httpd_can_network_connect_db on

# setsebool httpd_can_sendmail on

要讓httpd寫入的目錄，例如上傳目錄
# chcon -t httpd_sys_rw_content_t /path/to/upload

要讓httpd讀取的目錄，例如網頁目錄 (預設的/var/www/html已設定)
# chcon -R -t httpd_sys_content_t /path/to/html

安裝PHP7^[1]

如果你已有安裝其他版本的PHP，請先移除它們

# yum remove php*

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum install php70w php70w-opcache

# yum install php70w-mysqlnd php70w-mbstring php70w-gd

# yum install php70w-pecl-imagick

=== 111.10.6 更新，因為此時的php版本已經到7.4.x[2] =====

# yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

# yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

# yum -y install yum-utils

# yum-config-manager --enable remi-php74

主要使用 remi來更新

# yum update

# yum install php php-cli

# php -v
PHP 7.4.32 (cli) (built: Sep 28 2022 09:09:55) ( NTS )
Copyright (c) The PHP Group

設定 vi /etc/php.ini

; 時區
date.timezone =  "Asia/Taipei"
; Session 時間改一天
session.gc_maxlifetime = 86400
; 記憶體，預設128M
memory_limit = 1024M
; 上傳大小限制和時間
post_max_size = 20M
upload_max_filesize = 20M
max_input_time = 120
default_socket_timeout = 600

安裝mariadb10.9

建立 yum repository

# vim /etc/yum.repos.d/MariaDB.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.9/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

# yum install MariaDB-server MariaDB-client

安裝 phpmyadmin

到官網 https://www.phpmyadmin.net/ 找尋下載連結

# cd /var/www/html
# wget https://files.phpmyadmin.net/phpMyAdmin/5.2.0/phpMyAdmin-5.2.0-all-languages.zip
# unzip phpMyAdmin-5.2.0-all-languages.zip

修改設定檔

# cd phpMyAdmin-5.2.0-all-languages/ 請視版本修改目錄
# mv config.sample.inc.php config.inc.php
# vi config.inc.php

去 [3] phpMyAdmin blowfish secret generator 取得secret，這個頁面只要點開就會隨機產生一組，只要貼上即可

$cfg['blowfish_secret'] = 'l54xE78nRD;7Fiz{K85X5e{U9iwm7k;X';

建立暫存目錄以提升速度

# mkdir tmp
# chmod 777 tmp
# chcon -t httpd_sys_rw_content_t tmp

開啟頁面，警告消失。

啟動

# systemctl enable httpd

# systemctl enable mariadb

# systemctl start mariadb

# systemctl start httpd

你的檔案放在 /var/www/html中

開你的網頁 http://x.x.x.x/ 來測試能不能看到歡迎畫面，我發現這頁還是responsive web design。

如果出現forbidden代表selinux或檔案權限問題，如果等很久沒頁面是防火牆問題。

其他的問題原因太複雜得CASE by CASE
