带有 MSSQL 的 PHP 未安装在 centos 7 中

For that, i refered some site and found solutions. But that also not working. Here i am trying to installing php5-sybase, but getting some error,

yum install php5-sybase
Loaded plugins: fastestmirror, langpacks
apt.sw.be_redhat_el2.1_en_mirrors-rpmforge| 1.9 kB  00:00:00
remi-safe                                 | 2.9 kB  00:00:00


 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: rpmforge

如何解决这个问题.

推荐答案

要在 CentOS 上安装适用于 SQL Server 的 PHP 驱动程序，以下是我的建议:

sudo su
curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/mssql-release.repo
exit
sudo ACCEPT_EULA=Y yum install msodbcsql
sudo yum install unixODBC-devel
yum groupinstall "Development Tools"
sudo pecl install sqlsrv pdo_sqlsrv
sudo echo "extension= pdo_sqlsrv.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:s*||"`
sudo echo "extension= sqlsrv.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:s*||"`

<?php
$serverName = "localhost";
$connectionOptions = array(
    "Database" => "SampleDB",
    "Uid" => "sa",
    "PWD" => "your_password"
);
//Establishes the connection
$conn = sqlsrv_connect($serverName, $connectionOptions);
if($conn)
    echo "Connected!"
?>
