如何在logrotate.conf中重新启动服务

Question

我有一个脚本，它正在/var/log/vinaqua中生成日志。我想使用logrotate来管理这些日志。为此，我在/etc/logrotate.d/vinaqua文件中添加了以下代码

/var/log/venaqua{
daily
prerotate
/bin/echo "`date` Starting Logrotate" >> /log/var/venaqua
endscript
rotate 5
compress
minsize 1M
create 0644 root root
postrotate
/bin/systemctl restart venaqua.service
/bin/echo "`date` Logrotate Completed" >> /log/var/venaqua
endscript
}

我正在通过进行测试

sudo logrotate -v -f /etc/logrotate.conf

我在上出错了

rotating pattern: /var/log/venaqua forced from command line (5 rotations)
empty log files are rotated, only log files >= 1048576 bytes are rotated, old logs are removed
considering log /var/log/venaqua
Now: 2019-10-25 13:05
Last rotated at 2019-10-25 12:49
log needs rotating
rotating log /var/log/venaqua, log->rotateCount is 5
dateext suffix '-20191025'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'

Answer 1

cannot create /log/var/venaqua: Directory nonexistent告诉一切。您已经在初始日志定义/var/log/venaqua{和预转脚本中的后续路径>> /log/var/venaqua之间切换了/var/log/和/log/var。这个错误也出现在您的postrotate脚本中。
