在 SQLplus 命令提示符下 让按上下键就可以跳回前面执行过的命令
下载 rlwrap :
我下载的是 rlwrap-0.37.tar.gz
# tar xzvf rlwrap-0.37.tar.gz
进入解压目录 rlwrap-0.37
#./configure
#make
#make install
如果在执行configure时失败（ make 不通过），就看一下失败提示。一般是需要安装一些依赖包，到 centos6.3 的第一张光盘里的Packages目录下找需要的包并安装。下面是我安装需要的包：
[root@localhost Packages]# rpm -ivh readline-6.0-4.el6.x86_64.rpm
warning: readline-6.0-4.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

[root@localhost Packages]#
然后再到目录 rlwrap-0.37 下：
#./configure
#make
#make install
安装 rlwrap 成功！ 赶快试试吧！
# rlwrap sqlplus "/as sysdba"
