找不到 cron 配置文件

我有 CentOS 7 並試圖訪問一個看起來有點像這樣的配置文件：

# Cron configuration options

# For quick reference, the currently available log levels are:
#   0   no logging (errors are logged regardless)
#   1   log start of jobs
#   2   log end of jobs
#   4   log jobs with exit status != 0
#   8   log the process identifier of child process (in all logs)
#

我的目標是禁用 cron 日誌記錄。

我試過用Google搜尋，顯然有些人有類似的文件/etc/default/cron，/etc/rsyslog.d/50-Default.conf但是當我搜尋它們時，這些文件都不存在。我確實有/etc/rsyslog.conf並嘗試使用cron.none.* /var/log/messages（我沒有/var/log/syslog）禁用 cron 日誌記錄，但我仍然在我的遠端伺服器上獲取 cron 日誌。

**如何停止 cron 日誌（但不是 cron 本身）？**我所做的一切似乎都無法阻止他們。

CentOS/RHEL 7 使用 cron 的cronie實現。您在那裡顯示的文件與vixie cron相關，用於 Debian 等發行版。

Vixie Cron V3.0
December 27, 1993
[V2.2 was some time in 1992]
root@debian:/#

預設情況下，cronie將/var/log/cron使用以下/etc/rsyslog.conf條目發送所有 cron 消息

[root@centos7 ~]# grep ^cron /etc/rsyslog.conf
cron.*                                                  /var/log/cron
[root@centos7 ~]#

要更改它們的寫入位置，請修改文件並重新啟動 rsyslog。無需重新啟動 cron。

[root@centos7 ~]# sed -i 's!/var/log/cron!/var/log/bob!' /etc/rsyslog.conf
[root@centos7 ~]# grep ^cron /etc/rsyslog.conf
cron.*                                                  /var/log/bob
[root@centos7 ~]# systemctl restart rsyslog
[root@centos7 ~]# tail /var/log/bob
Jul  7 19:16:41 centos7 crontab[8581]: (root) LIST (root)
Jul  7 19:17:01 centos7 CROND[8587]: (root) CMD (/bin/touch /tmp/foo)
[root@centos7 ~]#

並由@doneal24 指出要完全丟棄條目，根據您的原始問題，您將使用/etc/rsyslog.conf如下行

cron.* ~
