其他¶

64位ubuntu14.04运行32位程序:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo apt-get install libz1:i386


[问]如何查询linux服务器是64位还是32位:

32位的系统中int类型和long类型一般都是4字节, 64位的系统中int类型还是4字节的, 但是long已变成了8字节inux系统中可用"getconf WORD_BIT"和"getconf LONG_BIT"获得word和long的位数. 64位系统中应该分别得到32和64(getconf命令还可以获取系统的基本配置信息，比如操作系统位数，内存大小，磁盘大小等. ``$getconf -a`` 可以看到详细的系统信息):

  #getconf LONG_BIT
  #getconf WORD_BIT

//X686或X86_64则内核是64位的，i686或i386则内核是32位的:
  #uname -a

直接看看有没有/lib64目目录的方法。64位的系统会有/lib64和/lib两个目录，32位只有/lib一个
以下命令:

  #file /sbin/init
  #file /bin/cat
  #uname -m
  #arch
  # echo $HOSTTYPE

查看cpu是多少位的:
  #more /proc/cpuinfo

error: error creating symbolic link ‘/usr/share/man/man1/xxx’ [1]

在debian中安装软件时报上面错误，解决方法:
$ mkdir -p /usr/share/man/man1
