1.将所有容器的输出路由到远程 rsyslog 服务器
1.修改 rsyslog 配置文件/etc/rsyslog.conf, 从中找到 “# Provides UDP sysilog recepion"语句。并将该处的以下两行配置代码行首的“#”字符删除（取消注释）
[root@host1 ~]# vi /etc/rsyslog.conf
[root@host1 ~]# cat /etc/rsyslog.conf
# rsyslog configuration file# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# or latest version online at http://www.rsyslog.com/doc/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html#### GLOBAL DIRECTIVES ##### Where to place auxiliary files

# # Remote Logging (we use TCP for reliable delivery)
# # remote_host is: name/ip, e.g. 192.168.0.1, port optional e.g. 10514
#Target="remote_host" Port="XXX" Protocol="tcp") 2.保存该配置文件，执行 systemctl restart rsyslog 命令重启 rsyslog, 然后检查514端口是否
已开启
[root@host1 ~]# systemctl restart rsyslog
[root@host1 ~]# netstat -antup | grep 514
udp 0 0 0.0.0.0:514 0.0.0.0:* 418069/rsyslogd
udp6 0 0 :::514 :::* 418069/rsyslogd 3.启动Logspout 容器，将日志转发到 Docker 主机上的syslog日志系统中
[root@host1 ~]# docker run --rm --name="logspout" --volume=/var/run/docker.sock:/var/run/docker.sock

4.打开另一个终端窗口（或者标签页，下同)，执行tail-f/var/log/messages 命令使用 tail 工具实时监控系统日志文件/var/og/messages
[root@host1 ~]# tail -f /var/log/messages

[root@host1 ~]# docker run --rm -d --name redis redis

[root@host1 ~]# 2.通过 HTTP 查看 Logspout 收集的日志
1.只需读取 HTTP数据流，即可实时查看生成的聚合日志。可以使用 Logspout 的 HTTP流模块，实时查看由它聚合的本地日志，而不用提供日志路由的URI，如执行以下操作：
[root@host1 ~]# docker run --rm -d --name="logspout" \--volume /var/run/docker.sock:/var/run/docker.sock \--publish=127.0.0.1:8000:80 \gliderlabs/logspout
cfd9130ed802c6d28dd2e67f85899510016d9f423586802bc6a6d447bd727e4a2.使用 curl 观察容器的日志流
[root@host1 ~]# curl http://127.0.0.1:8000/logs
3.打开另一个终端窗口，执行容器操作。这里启动 Redis 容器，切回前面的终端窗口，会发现关于 Redis 容器启动的日志流，如下所示
