linux关闭sendmail服务
方法一:
a.
[root@sample ~]# /etc/rc.d/init.d/sendmail stop --关闭sendmail服务
或者
[root@sample ~]# service sendmail stop --关闭sendmail服务
Shutting down sendmail: [ OK ]
Shutting down sm-client: [ OK ]
b.
[root@sample ~]# chkconfig sendmail off --关闭sendmail自启动
c.
[root@sample ~]# chkconfig --list sendmail --确认sendmail自启动已被关闭(都为off就OK)
sendmail 0:off 1:off 2:off 3:off 4:off 5:off 6:off
如果chkconfig --list sendmail显示如下:
sendmail 0:off 1:off 2:on 3:on 4:on 5:on 6:off
可以看到在启动模式2/3/4/5都是默认启动的,通常生产系统一般是3,可以按层级关闭服务
[root@sample ~]# chkconfig --level 2 sendmail off
[root@sample ~]# chkconfig --level 3 sendmail off
[root@sample ~]# chkconfig --level 4 sendmail off
[root@sample ~]# chkconfig --level 5 sendmail off
[root@sample ~]# chkconfig --list sendmail
sendmail 0:off 1:off 2:off 3:off 4:off 5:off 6:off
方法二:
[root@sample ~]# ntsysv
将sendmail前面[ ]中的*去掉即可。
