rsyslog 直接kill进程,在重新启动会全部发送日志

<pre name="code" class="html">jrhapt11:/root# ps -ef | grep rsyslog
root      8233     1  0 17:42 ?        00:00:00 /sbin/rsyslogd -i /var/run/syslogd.pid
root      8342  8147  0 17:43 pts/1    00:00:00 grep rsyslog
jrhapt11:/root# kill -9 8233
You have mail in /var/spool/mail/root
jrhapt11:/root# service rsyslog start
Starting system logger:                                    [  OK  ]
jrhapt11:/root# 

这种方式 日志会全部重发

/***

jrhapt11:/root# service rsyslog stop
Shutting down system logger:                               [  OK  ]
jrhapt11:/root# service rsyslog start
Starting system logger:                                    [  OK  ]


这种情况日志不会重发
