这次没有报错

总结：我认为是因为自己的mysql是在最小化安装的时候选择安装的，而不是自己编译安装的， 如果是自己编译安装，那么按照最开始的去做就可以。简单说就是两种安装方式，文件的路径是有差异的。

make install

[root@BENET3 postfix]# make install

继续排错

[root@BENET3 postfix]# hostname
BENET3.0

估计是和这个有关系

将hostname改成benet之后重启

[root@BENET ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=BENET
[root@BENET ~]#

再次执行make install
