php安装

配置PHP源

安装完成后默认都是禁用的源

yum install -y yum-utils
yum install -y epel-release -y
yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
#yum install -y https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm

启用某个版本的源

yum-config-manager --enable remi-php74

禁用某个版本的源

[root@localhost ~]# yum-config-manager --disable remi-php81

查看已启用的源

[root@localhost ~]# yum repolist enabled | grep php
 * remi-php74: ftp.riken.jp
remi-php74       Remi's PHP 7.4 RPM repository for Enterprise Linux 7 - x    463

开始默认安装

#在线默认安装
yum install -y php

wordpress使用这个步骤安装

一步到位，只下载不安装

mkdir -p /root/php7.4-wordpress
yum -y install php php-mysqlnd php-fpm php-opcache php-pecl-memcached redis php-redis --downloadonly --downloaddir=/root/php7.4-wordpress

这个是分开按照的

#直接在线安装
yum -y install php php-mysqlnd php-fpm

#php-fpm启停
systemctl stop php-fpm.service
systemctl enable php-fpm.service
systemctl start php-fpm.service
systemctl restart  php-fpm.service 
systemctl status php-fpm.service

#wordpress加速必备扩展
yum -y install php-opcache
yum -y install php-pecl-memcached

#安装redids服务wordpress扩展
yum -y install redis
systemctl stop redis
systemctl enable redis
systemctl start redis
systemctl status redis

#安装php redis扩展
