2.开始安装rlwrap软件：

[root@localhost vagrant]# cd rlwrap-0.37/

##若出现报错终止：

1)
[root@s10 cacti]# ./configure

checking build system type... Invalid configuration `x86_64-unknown-linux-': machine `x86_64-unknown-linux' not recognized

configure: error: /bin/sh config/config.sub x86_64-unknown-linux- failed

解决：安装yum
 yum install -y libtool*
 然后将

/usr/share/libtool/config.sub

/usr/share/libtool/config.gues

复制到你当前要configure目录下

（比如你要装 mysql，进入解压后的文件夹进行如下操作：

cp /usr/share/libtool/config.sub .

cp /usr/share/libtool/config.guess . ）

然后./configure --enable-shared --enable-static
 2)

configure: error:

You need the GNU readline library(ftp://ftp.gnu.org/gnu/readline/ ) to build

解决：：：
 yum install readline-devel readline

再次进行安装：
  [root@localhost rlwrap-0.37]# ./configure && make && make install

3.安装完成验证：

环境变量添加：
vi ~/.bash_profile
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
alias dgmgrl='rlwrap dgmgrl'
alias asmcmd='rlwrap asmcmd'

source ~/.bash_profile
