配置文件格式

HAProxy's configuration process involves 3 major sources of parameters :

• the arguments from the command-line, which always take precedence
• the "global" section, which sets process-wide parameters
• the proxies sections which can take form of "defaults", "listen", "frontend" and "backend".

The configuration file syntax consists in lines beginning with a keyword referenced in this manual, optionally followed by one or several parameters delimited by spaces.
