    安裝步驟

    CentOS 6.5

    wget http://dl./pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

    wget http://rpms./enterprise/remi-release-5.rpm

    rpm -ivh epel-release-5-4.noarch.rpm

    rpm -ivh remi-release-5.rpm

    CentOS 6.5

    wget http://dl./pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

    wget http://rpms./enterprise/remi-release-6.rpm

    rpm -ivh epel-release-6-8.noarch.rpm

    rpm -ivh remi-release-6.rpm

    完成后的設(shè)置

    ls -1 /etc/yum.repos.d/epel* /etc/yum.repos.d/remi.repo

    返回

    /etc/yum.repos.d/epel.repo

    /etc/yum.repos.d/epel-testing.repo

    /etc/yum.repos.d/remi.repo

    允許remi repository

    vi /etc/yum.repos.d/remi.repo

    編輯[remi]下的enabled選項從0設(shè)為1

    [remi]

    name=Les RPM de remi pour Enterprise Linux 6 – $basearch

    #baseurl=http://rpms./enterprise/6/remi/$basearch/

    mirrorlist=http://rpms./enterprise/6/remi/mirror

    enabled=1

    gpgcheck=1

    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

    至此，安裝完成。

    安裝完運行yum報錯：

    Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

    解決辦法：

    vi /etc/yum.repos.d/epel.repo

    編輯[epel]下的baseurl前的#號去掉，mirrorlist前添加#號。正確配置如下：

    [epel]

    name=Extra Packages for Enterprise Linux 6 – $basearch

    baseurl=http://download./pub/epel/6/$basearch

    #mirrorlist=https://mirrors./metalink?repo=epel-6&arch=$basearch

    failovermethod=priority

    enabled=1

    gpgcheck=1

    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

    再運行

    yum makecache
