Linux 环境下安装rlwrap工具

rlwrap项目是一个“readline包装器”，它使用GNU readline库来编辑任何其他命令的键

盘输入。通过rlwrap可以进行命令的上下切换，类似历史命令。

1、下载rlwrap rpm

rlwrap rpm包可以通过：https://centos.pkgs.org/  获取

 

安装这个包可以解决下面截图问题

rlwrap能解决方向键上下切换历史执行的sql，左右方向键乱码的问题可以通过shell终端解决，比如xshell方法如下：

2、安装rlwrap

[root@oracle ~]# rpm -ivh rlwrap-0.43-2.el7.x86_64.rpm 
warning: rlwrap-0.43-2.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 352c64e5: NOKEY
error: Failed dependencies:
    /usr/bin/python3.6 is needed by rlwrap-0.43-2.el7.x86_64
    perl(Data::Dumper) is needed by rlwrap-0.43-2.el7.x86_64

Package 4:perl-5.16.3-291.el7.x86_64 already installed and latest version
Nothing to do

centos7对应的是0.43版本，但是安装时提示需要py3.6和perl两个依赖包，perl已经安装，py版本是2.7

先解决perl问题：

[root@oracle ~]# yum -y install autoconf

在网上查资料，发现centos6用的0.42版本也能安装，测试下：

[root@oracle ~]# rpm -ivh rlwrap-0.42-.el6.x86_64.rpm
warning: rlwrap-0.42-.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY

[root@oracle ~]# 

OK了！

3、配置环境变量

切换到oracle用户，编辑.bash_profile增加

alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
alias lsnrctl='rlwrap lsnrctl'

[oracle@oracle ~]$ . .bash_profile

4、测试下
