这个可以执行，结果如下。
[gou@localhost onweb]$ ./msg_block_write
key=[610001be]
[gou@localhost onweb]$ ./msg_block_read
key=[610001be]
recv msg=[test haha,aaaaaaaaaaaaaaa],len=25[gou@localhost onweb]$ ./msg_block_write

没有/tmp/2这个文件执行结果。
[gou@localhost onweb]$ ./msg_block_write
key=[ffffffff]
[gou@localhost onweb]$ ./msg_block_read
key=[ffffffff]
recv msg=[test haha,aaaaaaaaaaaaaaa],len=25
