在 CentOS 6.3 上安裝 PHP 5.4.11

我PHP 5.3.3在我的CentOs 6.3伺服器上有，由於這個版本PHP是易受攻擊的，現在嘗試升級到PHP 5.4.11但預設儲存庫CentOs沒有，PHP > 5.3.3所以yum無法檢測到較新的版本。

remi然後我在我的伺服器上安裝了儲存庫

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

這些命令成功安裝了儲存庫

現在升級PHP的命令

yum --enablerepo=remi,remi-test update httpd mysql mysql-server php php-common 

但它失敗並顯示以下錯誤消息

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

如果我嘗試yum info php相同的錯誤消息

基本上在安裝這些儲存庫後yum無法正常工作，但 yum 更早工作。

如果我刪除這些儲存庫並嘗試yum它沒有任何錯誤。

我怎樣才能PHP升級到PHP 5.4.11版本？

編輯 @Michael建議我跑了

yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base epel extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors
`[root@www ~]# yum --obsoletes update
Loaded plugins: fastestmirror
Determining fastest mirrors
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

還是一樣的錯誤

網際網路連接執行良好，我檢查過

wget http://google.com

正如@Michael 建議的那樣，我跑了

URLGRABBER_DEBUG=1 yum check-update 最後出現以下錯誤

Problem with the SSL CA cert (path? access rights?)
2013-02-24 20:31:45,730 exception: [Errno 14] PYCURL ERROR 77 - "Problem with the SSL CA cert (path? access rights?)"
INFO:urlgrabber:exception: [Errno 14] PYCURL ERROR 77 - "Problem with the SSL CA cert (path? access rights?)"
2013-02-24 20:31:46,051 retrycode (14) not in list [-1, 2, 4, 5, 6, 7], re-raising
INFO:urlgrabber:retrycode (14) not in list [-1, 2, 4, 5, 6, 7], re-raising
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

因此，實際問題在於 SSL 證書，但為什麼它抱怨 SSL 證書，但它是有效的

添加新儲存庫後，請清除 yum 記憶體並更新系統，然後再嘗試安裝更多軟體包。

yum clean all
yum --obsoletes update

---

根據您更新的資訊，您的本地 CA 證書似乎已損壞或刪除。嘗試重新安裝它們：

yum reinstall ca-certificates

vi epel.repo

更改 https 中

mirrorlist= https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch= $basearch 到 mirrorlist= http://mirrors.fedoraproject.org/metalink?repo=epel-6&arch= $basearch

工作！
