rhel6.1 server 安装amule
- 博客分类：

在rhel6.1下安装amule2.2.6
1、安装wxWidgets-2.9.0
2、源码编译安装amule
3、设置/etc/profile
加入：export LD_LIBRARY_PATH=/usr/local/lib
不知道什么原因，在rhel server6.1上安装transmission总是有这样那样的错误，没办法不停降低transmission的版，在安装transmission1.8时顺利安装成功，没有高版本的各种部题，不知道什么原因。
下载transmission1.8的tar.bz的源码
解压，进入transimission目录，
1、./configure
2、make
3、make install
1、在／etc／yum.repos.d/里建一个以.repo结尾的文件，写入相应的yum信息。
vi /etc/yum.repos.d/local.repo
2、写入信息
［local］
name = yum
baseurl=file:///back/rhel
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
3、将镜像解压后根目录下的
