Linux下Oracle中SqlPlus时上下左右键乱码问题的解决办法
window下的sqlplus可以通过箭头键,来回看历史命令,用起来非常的方便。
但是在Linux下,会出现各种乱码,非常不方便,如下图所示,每次打错一个字符就需要重新打一遍。
解决办法:rlwrap 可以用来支持Oracle下sqlplus历史命令的回调功能,提高效率。
解决过程:
1、首先下载rlwrap和readline;
readline-6.3.tar.gz rlwrap-0.30.tar.gz
2、安装readline包
tar -zxvf readline-6.3.tar.gz cd readline-6.3 ./configure make make install
3、安装rlwrap
tar -zxvf rlwrap-0.30.tar.gz cd rlwrap-0.30 ./configure
出现问题:You need the GNU readline library(ftp://ftp.gnu.org/gnu/readline/ ) to build this program!
解决办法:yum install readline*,执行后出现如下问题

如果这些包安装失败,可以到官网上找这些包下载独立安装,安装无误后,在一次尝试:
可以从这个网址进行下载 ,包很全: http://ftp.riken.jp/Linux/centos/6/os/x86_64/Packages/ (需要翻墙)
安装下载的依赖包:
rpm -ivh --force readline-static-6.0-4.el6.x86_64.rpm ncurses-libs-5.7-4.20090207.el6.x86_64.rpm readline-devel-6.0-4.el6.x86_64.rpm ncurses-devel-5.7-4.20090207.el6.x86_64.rpm ncurses-base-5.7-4.20090207.el6.x86_64.rpm
然后再尝试安装rlwrap:
./configure make make install
使用方法:
1、首先配置一些信息,在oracle用户下的.bash_profile中添加以下信息:
alias sqlplus='/usr/local/rlwrap/bin/rlwrap sqlplus' (添加命令) alias sqlplus='rlwrap sqlplus' (去除每次都需要输入rlwrap的麻烦) alias rman='rlwrap rman'
2、source .bash_profile 后就可以使用了
