在CentOS 8上安装PHP 8.0

我们将使用REMI存储库在CentOS 8 / CentOS 7 Linux系统上安装PHP 8。安装有两种选择

  • 安装PHP 8.0作为主要的PHP版本
  • 与其他PHP版本一起安装PHP 8.0

将PHP 8.0安装为默认版本

如果您希望安装并将PHP 8.0作为默认版本，请使用以下命令。这意味着用PHP 8.0提供的软件包替换发行版中的基本软件包。

CentOS 8：

sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf -y install yum-utils
sudo dnf module reset php
sudo dnf module install php:remi-8.0 -y
sudo dnf install php -y
yum install php-fpm
systemctl enable php-fpm
yum install php-mysqlnd
yum install php-mbstring

安装compose:
php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"

上述 3 条命令的作用依次是：

  1. 下载安装脚本 －composer-setup.php－ 到当前目录。
  2. 执行安装过程。
  3. 删除安装脚本
全局安装：sudo mv composer.phar /usr/local/bin/composer
https://www.phpcomposer.com/

CentOS 7：

sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum -y install yum-utils
sudo yum-config-manager --disable 'remi-php*'
sudo yum-config-manager --enable remi-php80
sudo yum -y install php php-{cli,fpm,mysqlnd,zip,devel,gd,mbstring,curl,xml,pear,bcmath,json}

要安装任何其他PHP软件包，请使用命令语法：

sudo yum install php-xxx

检查PHP版本：

$ php --version
PHP 8.0.0RC4 (cli) (built: Nov 10 2020 10:57:27) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies

与其他PHP版本一起安装PHP 8.0

在CentOS 8上安装PHP 8.0：

sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf -y install yum-utils
sudo dnf module reset php
sudo dnf install php80

通过按键盘上的y键接受安装：

配置nginx访问php-fpm

1,准备测试用的目录和代码:
复制代码
[root@kubemaster web]# mkdir /data/web/phpweb
[root@kubemaster web]# mkdir /data/web/phpweb/html
[root@kubemaster web]# cd /data/web/phpweb/html
[root@kubemaster html]# vi info.php
[root@kubemaster html]# more info.php
<?php
phpinfo();
?>
复制代码
2,配置nginx
在nginx的配置文件中增加一个虚拟主机,使可以访问php
demo如下：
复制代码
      server {
        listen       8003;
        root   /data/web/phpweb/html;
 
        location ~ .php {
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;
        }
    }
复制代码
然后重启nginx
3，从浏览器访问php
访问:
http://127.0.0.1:8003/info.php

[root@vmcentos7 nginx]# yum install php80-unit-php

php实现SESSION跨域

稍微大一点的网站，通常都会有不只一个服务器，每个服务器运行着不同的功能模块或者不同的子系统，他们使用不同的二级域名，比如www.a.com、i.a.com、bbs.a.com。而一个整体性强的网站，用户系统是统一的，即一套用户名、密码在整个网站的各个子系统中都是可以登录使用的。各个服务器共享用户数据是比较容易实现的，只需要在后端放个数据库服务器，各个服务器...

关于php性能优化

php性能优化 1.尽量静态化： 如果一个方法能被静态，那就声明它为静态的，速度可提高1/4，甚至我测试的时候，这个提高了近三倍。 当然了，这个测试方法需要在十万级以上次执行，效果才明显。 其实静态方法和非静态方法的效率主要区别在内存：静态方法在程序开始时生成内存,实例方法在程序运行中生成内存，所以静态方法可以直接调用,实例方法要先成生实例,通过实例调用...

CentOS PostgreSQL 12 主从复制(主从切换)

主从复制1.基于文件的日志传送 创建一个高可用性（HA）集群配置可采用连续归档，集群中主服务器工作在连续归档模式下，备服务器工作在连续恢复模式下（1台或多台可随时接管主服务器），备持续从主服务器读取WAL文件。 连续归档不需要对数据库表做任何改动，可有效降低管理开销，对主服务器的性能影响也相对较低。 直接从一个数据库服务器移动WAL记录到另一台服务器被称为...
