To configure syslog-ng on a relay host, complete the following steps:

# 注释 ：要配置 syslog-ng 中继主机，按以下的步骤 ：

#     -）1、安装 syslog-ng 应用到中继主机

#     -）2、根据客户机配置网络 sources

#     -）3、创建一个网络 destination ，指向 syslog-ng 服务器

#     -）4、使用 log 语句连接网络 source 和网络 destination

#     -）5、为中继主机本身创建一个本地 source

#     -）6、使用 log 把本地 source 和 syslog-ng 服务器连接起来

#     -）7、设置过滤器和选项

Procedure 3.6. Configuring syslog-ng on relay hosts

1. Install the syslog-ng application on the host. See for details installing syslog-ng on specific operating systems.

2. Configure the network sources that collect the log messages sent by the clients.

3. Create a network destination that points to the syslog-ng server.

4. Create a log statement connecting the network sources to the syslog-ng server.

5. Configure the local sources that collect the log messages of the relay host.

6. Create a log statement connecting the local sources to the syslog-ng server.

7. Set filters and options (e.g., TLS encryption) as necessary.

In relay mode, syslog-ng cannot write messages received from network sources into files; the file() destination is disabled. The following sources are network sources: tcp(), tcp6(), udp(), udp6().
