错误信息

Linux CenterOs 64位中安装 MySQL-server-5.5.25a-1.rhel5.x86_64.rpm 出现以下错误
[root@localhost upload]# rpm -ivh MySQL-server-5.5.25a-1.rhel5.x86_64.rpm
error: Failed dependencies:
libaio.so.1()(64bit) is needed by MySQL-server-5.5.25a-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.5.25a-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.5.25a-1.rhel5.x86_64
从以上错误信息可以看出是因为缺少库libaio，所以需要安装libaio

安装libaio-0.3.107-10.el6.x86_64.rpm
