centos 7 安装 bluefish

1、首先配置epel源：

            （1）下载epel源epel-release-5-4.noarch.rpm并安装，然后yum install bluefish即可。

2、系统默认带的YUM源有时候不能满足需求，故使用fedora epelyum源是个不错的选择，epel所对应的RHEL7和Centos7已经出来了，替换方法如下：

如何检查epel是否安装成功？

使用一下命令：

# yum repolist

输出如下

[root@Lixiaolong ~]# yum repolist

如何使用epel源安装软件？

例如想查看cacti信息

# yum --enablerepo=epel info cacti

安装则执行以下命令：

# yum --enablerepo=epel install cacti

Note: Epel的配置文件在/etc/yum.repos.d/epel.repo.
