在linux下以yum安裝mcrypt(php-mcrypt)[含1張圖]

IT_man

首先check linux是否安裝php-mcrypt module

1. #rpm -qa | grep php-mcrypt

複製代碼

若無則以yum安裝

1. #yum install php-mcrypt

複製代碼

但它會提示說無php-mcrypt可供安裝，於是執行下列動作:
* a. b# k6 O/ m2 U+ O" Kfor CentOS 6.x x86:

再執行一遍 #yum install php-mcrypt，但這次出現的問題是

1. # yum install php-mcrypt
   
2. Loaded plugins: fastestmirror, refresh-packagekit

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

複製代碼

1. #vi  etc/yum.repos.d/epel.repo

複製代碼

將[epel]段下的 baseurl註解掉，並將mirrorlist恢復，如下:
. U$ @9 U" \. w* dbaseurl
1 y6 z8 K; F& ~1 s' M! K#mirrorlist
最後再執行一遍 #yum install php-mcrypt，這次終於順利安裝完成，會看到安裝如下的模組
