syslog-ng替换syslog备忘录

由于经常要装，所以在这里备忘一下：
syslog-ng is now installed!  To replace FreeBSD's standard syslogd
(/usr/sbin/syslogd), complete these steps:

1. Create a configuration file named /usr/local/etc/syslog-ng.conf
   (a sample named syslog-ng.conf.sample has been included in
   /usr/local/etc/syslog-ng). Note that this is a change in 2.0.2
   version, previous ones put the config file in
   /usr/local/etc/syslog-ng/syslog-ng.conf, so if this is an update
   move that file in the right place

2. Configure syslog-ng to start automatically by adding the following
   to /etc/rc.conf:

        syslog_ng_enable="YES"

3. Prevent the standard FreeBSD syslogd from starting automatically by
   adding a line to the end of your /etc/rc.conf file that reads:

        syslogd_enable="NO"

4. Shut down the standard FreeBSD syslogd:

     kill `cat /var/run/syslog.pid`

5. Start syslog-ng:

     /usr/local/etc/rc.d/syslog-ng start

===> SECURITY REPORT:
      This port has installed the following files which may act as network
      servers and may therefore pose a remote security risk to the system.
/usr/local/sbin/syslog-ng

      This port has installed the following startup scripts which may cause
      these network services to be started at boot time.
/usr/local/etc/rc.d/syslog-ng

      If there are vulnerabilities in these programs there may be a security
      risk to the system. FreeBSD makes no guarantee about the security of
      ports included in the Ports Collection. Please type 'make deinstall'
      to deinstall the port if this is a concern.
