redis-dump遇到的错误问题：/opt/rh/rh-ruby23/root/usr/bin/ruby: error while loading shared libraries: libruby.so.2.3: cannot open shared object file: No such file or directory

1、现象：

[root@localhost ~]# redis-dump -u 172.18.1.239:4501 -a 123456 -d 9 >db9.json
/opt/rh/rh-ruby23/root/usr/bin/ruby: error while loading shared libraries: libruby.so.2.3: cannot open shared object file: No such file or directory

2、原因：

加载lisbruby.s0.2.3无法加载

3、解决：

（1）找到库的位置

[root@localhost ~]# find / -name libruby.so.2.3
/opt/rh/rh-ruby23/root/usr/lib64/libruby.so.2.3

（2）将库连接加入到ld.so.conf中

[root@localhost ~]# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/opt/rh/rh-ruby23/root/usr/lib64/

（3）生效

[root@localhost ~]# /sbin/ldconfig -v

4、再尝试就可以了

[root@localhost ~]# redis-dump -u 172.18.1.239:4501 -a 123456 -d 9 >db9.json
