在openstack里面有时候删除instance时,volume无法跟着删除,可以自己编写脚本来实现, 脚本代码如下: #!/bin/bash for i in $(cat /root/host-del); do host_id=`nova list --all --ip $i |grep -w "$i" |awk '{print $2}'` volume_id=`cinder list --all |grep -w $host_id |a
#!/bin/bash #delete vm for vim in `nova list |awk '{if( NR > 2 ) {print $2}}'`;do nova delete $vim & done #Unbundling router for port in `neutron port-list --all |awk '{if( NR > 2 ) {print $2}}'`;do for router in `neutron router-list --all | awk
File Read 程序举例: public class FileRead { public static void main(Sting[] args) throws Exception { Configuration conf = new Configuration(); FileSystem fs = FileSystem.get(conf); InputStream in = new InputStream(); in = fs.open(new Path(args[0])); IOUt
