Spamassassin:无法打开文件 /usr/local/spamassassin/spamfilter.log:权限被拒绝

Spamassassin:无法打开文件 /usr/local/spamassassin/spamfilter.log:权限被拒绝

我正在尝试按照本教程操作

https://www.rosehosting.com/blog/how-to-install-and-integrate-spamassassin-with-postfix-on-a-centos-6-vps/

但 Spamassassin 给出了错误

[root@ip-172-99-99-99 ~]# service spamassassin restart
Stopping spamd:                                            [  OK  ]
Starting spamd: Jan  4 21:17:10.569 [22463] warn: logger: failed to open file /usr/local/spamassassin/spamfilter.log: Permission denied

                                                           [  OK  ]

即使它有权限!

[root@ip-172-99-99-99 ~]# ls -ld /usr/local/spamassassin /usr/local/spamassassin/*
drwx------. 2 spam spam 4096 Jan  3 20:02 /usr/local/spamassassin
-rw-r--r--. 1 spam spam    0 Jan  3 20:02 /usr/local/spamassassin/spamfilter.log


# sudo -u spam ls /usr/local/spamassassin/spamfilter.log
/usr/local/spamassassin/spamfilter.log
# sudo -u spam touch /usr/local/spamassassin/spamfilter.log

这是 sysconfig 文件

[root@ip-172-99-99-99 ~]# cat /etc/sysconfig/spamassassin
# Options to spamd
SAHOME=/usr/local/spamassassin
SPID_DIR=/var/run/spamassassin
SUSER=spam
SPAMDOPTIONS="-d -c -m5 --username ${SUSER} -H ${SAHOME} -s ${SAHOME}/spamfilter.log"

我已启用 SELinux。

# sestatus
SELinux status:                 enabled

# ls -Z /usr/local/spamassassin/
-rw-r--r--. spam spam unconfined_u:object_r:usr_t:s0   spamfilter.log

我尝试改变目录的上下文,但是失败了,尽管我是 root 身份。

chcon -Rv --type=spamc_home_t /usr/local/spamassassin
semanage fcontext -a -t spamc_home_t "/usr/local/spamassassin(/.*)?"

答案2

检查:
1)整个目录树的权限
2)记不清了,但守护进程可能想要重新创建文件,因此需要对该文件有执行权限
