无法在 RHEL5 上安装 PHP、MySQL答案

【问题标题】：Unable to install PHP, MySQL on RHEL5无法在 RHEL5 上安装 PHP、MySQL

【问题描述】：

我正在尝试在 RHEL 5.7 VM 上的 Apache Web 服务器上安装 PHP 和 MySql。我尝试使用以下 yum Remi 和 EPEL 存储库来做到这一点：

rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

每当我尝试这样做时，似乎都会出现“缺少依赖项”：

yum --enablerepo=remi,remi-test install mysql mysql-server php php-common

然后，我收到以下错误：

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

我已经有 httpd（我可以运行 service httpd start），每当我尝试安装 libaio 时，我都会得到这个：

[root@mod2014 rpm-gpg]# yum install --enablerepo=remi,remi-test libaio libaio-devel
Setting up Install Process
No package libaio available.
No package libaio-devel available.
Nothing to do

标签： rpm yum rhel

【解决方案1】：

正如您在this 网页上看到的那样，您尝试使用的存储库中没有 libaio rpm 包。我建议你将this CentOS repo 包含在你的 /etc/yum.repos.d/ 目录中，或者下载所有manually。

顺便问一下，使用这种过时的 RHEL 分发包的原因是什么？

【讨论】：

我手动安装了（几乎）所有东西，这对那个错误有效，但它仍然说需要 httpd，我已经安装了它。此外，CentOS 存储库说我需要 htmlview。我正在开发一个免费的 RHEL 虚拟机，他们为我提供了用于我自己的测试，所以我不是选择过时虚拟机的人。
@Kristin，那么当你yum install httpd 时，yum 会回答你什么？
@Kristin，您当前的 httpd 拥有哪个软件包？ rpm -q --whatprovides /usr/sbin/httpd
yum install httpd：设置安装过程没有可用的包 httpd。无事可做 rpm -q --whatprovides /usr/sbin/httpd error: file /usr/sbin/httpd: No such file or directory
@Kristin，在我看来，你的机器上没有安装 httpd 包，因为 /usr/sbin/httpd 丢失了。您可以使用rpm -qa | grep httpd 进行检查。我建议你什么也看不见。如果是这样，只需从 CentOS repo 下载 httpd 包并使用yum install 安装它（不要在没有紧急需要的情况下使用rpm -Uvh）。

【解决方案2】：

好吧，当“回答”问题的人问为什么你想这样做时（即，使用“旧”软件和存储库），这变得非常陈旧和累了。

底线：有许多正当理由 - 也有同样的理由不通过 Yum 自动更新和/或 RHEL 自动更新等进行更新。我的情况，例如，Web 主机公司让我们使用旧版本的 mysql（5.0.96-community 和 5.1）、PHP（5.2.13）和 Apache（2.2.15 和 2.2.22？） - 他们拒绝更改某些内容（即修改“已弃用” mysql_connect 命令和其他命令）到最新的 mysqli 和/或 PDO 格式，因此，当我们接管该站点时，代码只能使用 OLD 软件运行。所以，你看，这样做是有正当理由的。

所以，为了让我们有时间弄清楚什么是 mysqli，什么是 PDO，以及“如何”为那些更新（未弃用）的产品更改我们的软件和代码，我们必须保留旧代码！

但是，回答原帖：你可以做

yum --nogpgcheck localinstall some.rpm --nodeps

然后，通过--nodeps，您将能够绕过“依赖检查”。
