postfix报错postfix: fatal: parameter inet_interfaces: no local interface found for ::1
CentOS 7 crontab 不执行
报错 /bin/sh: root: command not found
解决: 检查文件( /var/spool/cron/root )及脚本(xxx.sh)是否正确
文件 /etc/crontab 全部内容
SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root # For details see man 4 crontabs # Example of job definition: # .---------------- minute (0 - 59) # | .------------- hour (0 - 23) # | | .---------- day of month (1 - 31) # | | | .------- month (1 - 12) OR jan,feb,mar,apr ... # | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat # | | | | | # * * * * * user-name command to be executed 12 * * * * rm -rf /tmp/tmp* & #12 * * * * sh /root/script/kill_firefox.sh #05 */2 * * * cd /root/script/ && ./proxy_server.sh 06 22 * * * cd /root/script/ && ./proxy_server.sh
查看crontab 状态

postfix 报错
出错信息:postfix: fatal: parameter inet_interfaces: no local interface found for ::1
解决1:断定IPv6在作怪,想起/etc/hosts文件里的IPV6的设定,决定注释掉。
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
再次启动Postfix(或重启服务器 reboot),正常启动。
systemctl start postfix.service
systemctl status postfix.service

解决2:
service postfix start总是FAILED. 最后没办法
vim /etc/postfix/main.cf
发现配置为:
inet_interfaces = localhost
inet_protocols = all
改成:
inet_interfaces = 127.0.0.1 #只能接受内部邮件,其它邮件不接受
inet_protocols = all
然后重启服务就好了,特此记录!
测试发送邮件:
mail -s "hello mimvp" yanggang@mimvp.com
