腾迅云centos7上crontab不执行

全不成功的 
]# crontab  -l

通过查看maillog,发现了下面的报错

cat  /var/log/maillog

stfix/sendmail[8087]: fatal: parameter inet_interfaces: no local interface found for ::1这是什么错误了(参数inet_interfaces:未找到::1的本地接口),又经过一番查找,终于找到了解决办法



#解决办法 
vim  /etc/postfix/main.cf

inet_interfaces = localhost

# Enable IPv4, and IPv6 if supported
inet_protocols = all


删掉或者注释  添加 

inet_interfaces = all

或者  只是 
将/etc/postfix/main.cf文件中inet_interfaces值改为all

还有写命令要 全部绝对路径
