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:
for CentOS 6.x x86:
4 ?( m; ]% V- K3 A5 X

1. # wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
   
2. # rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm
   * H' S; o) @1 w/ @" q  e; P! ?" O6 ^
3. # wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
   
4. # rpm -ivh epel-release-6-8.noarch.rpm

複製代碼

for CentOS 6.x x64

1. # wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
   % }* @! K7 f; q3 e& Y6 T& A
2. # rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
   $ k6 y1 J8 I1 @0 e7 X
3. # wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
   5 D& J2 i! ], O  H
4. # rpm -ivh epel-release-6-8.noarch.rpm

複製代碼

再執行一遍 #yum install php-mcrypt，但這次出現的問題是
7 j% t" z  @- @/ v: h8 n' ?: k

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

於是

1. #vi  etc/yum.repos.d/epel.repo

複製代碼

8 l) e. @( P, G1 q; T將[epel]段下的 baseurl註解掉，並將mirrorlist恢復，如下:
$ K3 O, w# v5 P- @) [baseurl
3 W( v( N9 Z- X2 Y! m: |#mirrorlist
% d% F5 Z: c; O/ Z) P4 g; t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

1. #service httpd restart
