关于rpm包卸载出现重复包的问题
1 rpm -qa rpm_name 有时候会出现重复的包
amp1:~/dir # rpm -qa zlib zlib-1.2.3-141.1 zlib-1.2.3-106.34 ##zlib包很危险，不卸载
2 rpm -e rpm_name 无法全部卸载，有时候只会卸载一个
amp1:~/dir # rpm -e zlib error: "zlib" specifies multiple packages
3 rpm -e --allmatches --nodeps rpm_name 会自动匹配rpm_name已安装的所有版本，并卸载
amp1:~/dir # rpm -e --allmatches --nodeps zlib You have new mail in /var/mail/root amp1:~/dir # ##现在不报错了，但是问题来了
4 把zlib全部卸载了之后，哈哈，逗B了^_^
amp1:/home/soft/software/myshell # ./run_install_1.sh rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory rpm -ivh zlib-1.2.3-141.1.x86_64.rpm --force is error
5 这只是个例子，所以记得不要卸载了zlib，很危险
6 对于其他的安装包，如果出现specifies multiple packages导致不能卸载的话，就可以用
rpm --help | grep allmatches rpm --allmatches rpm_name #选项进行处理。
7 有的时候64位系统也需要兼容32位的库，所以就会有装两个包的问题。这是正常的。
