Swap file ".." already exists!

 例：使用vi jetty_stdout.log时 会生成一个 jetty_stdout.log.swp 文件, 然后再开个终端 vi jetty_stdout.log 时会提示：
      【“Swap file "jetty_stdout.log" already exists![O]pen Read-Only, (E)dit anyway, (R)ecover, (Q)uit:】  

原因：This is the result of not properly closing an open buffer, usually because of a lost ssh connection. If there were unsaved changes, they can be recovered from this swap file.

处理方法： 打开 /etc/vimrc 并添加 set noswapfile 后 OK

=================================================

1、vi是vim的别称，所以直接编译/etc/vimrc即可

[admin@inc logs]$ which vi
alias vi='vim'
        /usr/bin/vim
