執行某些命令時，有缺少共用庫的報錯：

error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

解決辦法：

1、執行命令： yum whatprovides libstdc++.so.6

admin@rocketmq-master1 ~]# yum whatprovides libstdc++.so.6

2.yum install -y libstdc++-4.4.6-4.tl1.i686

如果系統中存在低版本的64位庫，則會因為版本不一致而報錯

報錯：

--> Finished Dependency Resolution

Error: Protected multilib versions: libstdc++-4.4.6-4.el6.i686 != libstdc++-4.4.6-3.el6.x86_64

You could try using --skip-broken to work around the problem

You could try running: rpm -Va --nofiles --nodigest

可先升級相應64位庫再安安裝32位庫

yum update libstdc++-4.4.6-3.el6.x86_64
