Question

我正在尝试在RHEL 5.7 VM上的Apache Web服务器上安装PHP和MySql。我试着用下面的yum Remi和EPEL回购来做这件事：

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，看起来都有“缺失依赖”：

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.

我已经有了httpd（我可以运行服务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

Answer 1

正如您在this网页上看到的那样，您尝试使用的仓库中没有 libaio rpm包。我建议你将this CentOS repo包含到你的/etc/yum.repos.d/目录中或下载所有manually。

那么，使用这种过时的RHEL分配的原因是什么？

Answer 2

好吧，当人们回答＆＃34;时，这会变得非常老旧。问题是要求为什么你想这样做（即使用＆＃34;旧的＆＃34;软件和存储库）。

底线：有许多有效原因 - 同样，通过Yum自动更新和/或RHEL自动更新等原因也是相同的原因。我的情况，例如，Web主机公司让我们保持OLD版本的mysql（5.0.96-community和5.1），PHP（5.2.13）和Apache（2.2.15和2.2.22？） - 他们拒绝改变一些东西（即修改＆＃ 39;弃用mysql_connect命令＆＃39;以及其他命令）到最新的mysqli和/或PDO格式，所以，当我们接管网站时，代码只能使用 OLD 软件运行。所以，你知道，这样做有充分的理由。

所以，让我们有时间弄清楚什么是mysqli，什么是PDO和＆＃34;如何＆＃34;我们是否更改了那些更新（非弃用）产品的软件和代码，我们必须保留旧代码！

但是，要回答原始海报：你可以做到

yum --nogpgcheck localinstall some.rpm --nodeps

然后，通过--nodeps，您将能够绕过＆＃34;依赖性检查。＆＃34;

无法在RHEL5上安装PHP，MySQL
