似乎这个话题很受欢迎...所以我想我的 logrotate 无法轮换 tomcat 日志,这有问题。Logrotate 配置设置/etc/logrotate.d/tomcat
为
/opt/tomcat/apache-tomcat-8.5.37/logs/catalina.out
{
daily
missingok
copytruncate
rotate 15
}
logrotate.conf 是:
> cat /etc/logrotate.conf
# see "man logrotate" for details
# rotate log files weekly
weekly
# keep 4 weeks worth of backlogs
rotate 12
# create new (empty) log files after rotating old ones
create
# use date as a suffix of the rotated file
dateext
# uncomment this if you want your log files compressed
compress
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp and btmp -- we'll rotate them here
/var/log/wtmp {
... skipped ...
}
/var/log/btmp {
... skipped ...
}
报告的问题audit.log
是

usr_t
因此,让我感到神秘的是,如果目录和其中的文件var_log_t
根据策略被标记为正确,为什么 logrotate 会尝试创建具有上下文的文件:
> semanage fcontext -l | grep logs
... skipped ...
/opt/tomcat/apache-tomcat-8.5.37/logs/ all files system_u:object_r:var_log_t:s0
/opt/tomcat/apache-tomcat-8.5.37/logs all files system_u:object_r:var_log_t:s0
/opt/tomcat/apache-tomcat-8.5.37/logs/catalina.out all files system_u:object_r:var_log_t:s0
可以采取哪些步骤来进一步排除故障?
(这是我在 Unix 和 Linux 部分发布的一个问题的副本)
答案1
所以问题就出来了。问题出在上下文定义上。相反,这 3 个定义
> semanage fcontext -l | grep logs
... skipped ...
/opt/tomcat/apache-tomcat-8.5.37/logs/ all files system_u:object_r:var_log_t:s0
/opt/tomcat/apache-tomcat-8.5.37/logs all files system_u:object_r:var_log_t:s0
/opt/tomcat/apache-tomcat-8.5.37/logs/catalina.out all files system_u:object_r:var_log_t:s0
已经引入了适当的替代方法
/opt/tomcat/apache-tomcat-8.5.37/logs(/.*)?
