[root@cacti bin]# ./pediags --show all
./pediags: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

问题原因和解决办法：
其实这个问题就是你64位的操作系统没有32位的类库
Linux的有些软件需要32位运行库才能运行，如Dr.com客户端等
yum在线安装： sudo
或者： sudo yum install ia32-libs.i686
ubuntu下： sudo apt-get install ia32-libs

采用yum安装解决：
yum install xulrunner.i686 -y
