【问题描述】：

无论我遵循什么教程，我都会遇到这个错误。这是example tutorial.

[jalal@goku ~]$ sudo yum install epel-release yum-utils
Package epel-release-7-11.noarch already installed and latest version
Package yum-utils-1.1.31-50.el7.noarch already installed and latest version
[jalal@goku ~]$ sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
Error: Nothing to do

系统规格为：

$ uname -a
Linux goku.bu.edu 3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

我应该如何在 CentOS 7 上安装 php 7.x？

另外，如果我忽略它并按照下面的命令，（即使我已经删除了 php5.x）它会继续安装 php 5.x：

【问题讨论】：

  • 你能做一个yum update吗？
  • 1/ 您有 4 个 PHP、base、IUS、webtatic 和 remi 提供程序。这只会引发问题。禁用 IUS 和 webtatic。还要检查“优先”插件。
  • 是的，yum 更新没有帮助
  • 这能回答你的问题吗？ How do I change the default PHP base-version on shell?

标签： php installation centos


【解决方案1】：

首先，您不需要 Centos 上的 Remi 存储库来获取 PHP 7，但目前（就像今天一样）您确实需要它用于 PHP 7.3。

但是，如果您想安装 PHP 7 在 Centos 上编辑 7.2（我现在推荐用于生产），您可以使用 epel repository：

首先检查您是否安装了正确的存储库：

$ yum repolist | grep -e ius -e remi

如果您还没有这些存储库之一，则需要安装它。

之后，只需删除旧的 PHP 并安装 PHP 7（IUS 的 7.2 或 remi 的 7.3）即可：

$ yum remove php* -y
$ yum install php72u

编辑

根据 Remi 的评论，php72u 实际上来自我没有注意到的 IUS！ 要从 remi 存储库获取 PHP 7.3，您可以运行 yum update 或：

$ yum install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json

【讨论】：

  • php72u 不是来自 EPEL ！ （它来自 IUS，另一个 3rd 方 repo，它提供“一些”php 版本）
  • 天哪，你是对的。我什至从未注意到这一点。 EPEL 仍为 5.4（虚幻）。立即编辑答案
【解决方案2】：

在 RHEL 7 服务器上安装 PHP 7.x 的步骤

1) 启用 EPEL、RHEL 7 服务器可选存储库并安装 remirepo rpm

Login to your RHEL 7 Server and run the beneath commands one after the another to enable EPEL repository, install remirepo and enable RHEL 7 Server optional repository

[root@user~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@user ~]# wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
[root@user ~]# rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
[root@user ~]# subscription-manager repos --enable=rhel-7-server-optional-rpms

2) 配置 PHP 7.x 仓库

[root@user ~]# yum install yum-utils
[root@user ~]# yum-config-manager --enable remi-php72

3) 安装 PHP 7.2 及其依赖项

[root@user ~]# yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysql -y

4) 验证 PHP 版本

[root@user ~]# php -v
