在Red Hat Enterprise Linux Server release 6.6 (Santiago)上安装了Symantec Backup Exec Remote Agent 2010后，启动Backup Exec Remote Agent 2010启动服务时报错。
[root@getlnx15 be]# /etc/init.d/VRTSralus.init start
Starting Symantec Backup Exec Remote Agent ..............................
Starting Symantec Backup Exec Remote Agent: [FAILED]
检查日志时发现如下错误信息：: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
[root@getlnx15 ~]# cd /var/VRTSralus/
[root@getlnx15 VRTSralus]# ls

在搜索一些资料后，从网上下载了libstdc++.so.5文件，并将其放置在/usr/lib,但是发现这样 处理其实无法解决问题。在搜索一番资料后，发现只需要安装compat-libstdc++-33-3.2.3-69.el6.x86_64.rpm即 可。如下所示，安装了对应包以后，Symantec Backup Exec Remote Agent 2010成功启动！

那么compat-libstdc++- 33-3.2.3-69.el6.x86_64.rpm与libstdc++.so.5是什么关系，其实使用rpm -ql命令就可以查找一个rpm包里面包含哪些文件，如下所示，compat-libstdc++- 33-3.2.3-69.el6.x86_64.rpm里面包含文件libstdc++.so.5，这也是为何安装compat-libstdc++- 33-3.2.3-69.el6.x86_64.rpm即可解决问题的原因。
[root@getlnx15 cdrom]# rpm -ql compat-libstdc++-33-3.2.3-69.el6.x86_64
/usr/lib64/libstdc++.so.5
/usr/lib64/libstdc++.so.5.0.7

小知识点：
查看一个rpm包包含哪些文件，可以有两种方式：
1：一个没有安装过的软件包，使用rpm -qlp rpm-filename.rpm
2：一个已经安装过的软件包，使用rpm -ql packet-name
查看一个文件属于哪个rpm包， rpm -qf /path/filename
