一.nginx配置文件的基本结构

.... events { .... } http { .... server { ..... } server { .... } }

虚拟主机的配置

http { server { listen 80; server_name _*; access_log /logs/default.access.log; location /{ index index.html root /data0/docs/docs } } }

二.日志

1.关于日志的指令

关于日志的两条指令，log_format(指定日志的格式)和access_log(日志存放的路径)

log_format main \'$remote_addr - $remote_user [$time_local] "$request" \'
\'$status $body_bytes_sent "$http_referer" \'
\'"$http_user_agent" "$http_x_forwarded_for"\';

access_log logs/access.log main;

host.access.log中按照log_format格式记录的日志

192.168.41.100 - - [24/May/2017:22:06:55 +0800] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36" "-"

2.日志文件的切割

通过信号量USER1重新生成新的日志

mv ../logs/access_log 20170524.log //先将原来的日志备份

kill -USR1 \'cat /logs/nginx.pid\' //让nginx重新生成一个新的文件

3.定时切割日志的脚本

kill -HUP nginx master pid == kill -HUP `cat nginx.pid`

这里的引号为单反引号
