sudo yum install erlang emacs
首先要安装erlang，其次要安装emacs。
我们以emacs作为erlang代码的编辑器。其可以提供很好的语法高亮，智能缩进，智能填充等功能。
首先在home目录下配置.emacs文件（如果没有需要创建），使其支持erlang mode
假设您的erlang的安装目录为/usr/lib/erlang，注意配置中涉及的目录，需要与您的安装环境相匹配。
;; setup erlang mode ;; add the location of the elisp files to the load-path (setq load-path (cons "/usr/lib/erlang/lib/tools-2.6.6.5/emacs" load-path)) ;; set the location of the man page hierarchy (setq erlang-root-dir "/usr/lib/erlang") ;; add the home of the erlang binaries to the exec-path (setq exec-path (cons "/usr/lib/erlang/bin" exec-path)) ;; load and eval the erlang-start package to set up ;; everything else (require 'erlang-start)
这样您的emacs已经支持erlang mode了。
随后您启动emacs，输入M-x erlang-mode 切换到erlang模式。

使用emacs 需要根据自己的需求加载相应的el文件，例如加载行号的话需要网上下载 linum.el 放到"usr/share/emacs/site-lisp/"下面,然后在/root目录下创建一个 .emacs 的文件 在文件里面写下相应的代码进行设置.
文件里面的代码如下：（例子）

加载usr/share/emacs/site-lisp/下的文件的时候要require 然后再进行相应的设置。
