shell脚本-Nginx访问日志自动按天切割

shell脚本-Nginx访问日志自动按天切割

前言

日志如果一直不归档分类，access.log文件会逐渐增大，后续难以获取相应信息。

1.通过kill USR1 nginx.pid 可以创建新的access.log文件，所以我们每天整点把前一天的log日志文件移动指定文件夹下，再创建一个新的access.log文件记录当日的日志即可

kill USR1 `/usr/local/nginx/logs/nginx.pid`

2.而nginx.pid也记录在/usr/local/nginx/logs/nginx.pid，或者/var/run/nginx.pid下面

shell脚本

#!/bin/bash
# 将每天给的log日志文件按月份归档
# 例如 /usr/local/nginx/logs/2023-7/access.log_2023-7-16

LOG_DIR=/usr/local/nginx/logs
YESTERDAY_TIME=`date -d "yesterday" +%F`
LOG_MONTH_DIR=$LOG_DIR/`date +"%Y-%m"`
LOG_FILE_LIST="access.log"

for LOG_FILE in $LOG_FILE_LIST;do
        [ ! -d $LOG_MONTH_DIR ] && mkdir -p $LOG_MONTH_DIR
        mv $LOG_DIR/$LOG_FILE $LOG_MONTH_DIR/${LOG_FILE}_${YESTERDAY_TIME}
done

kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`

[root@localhost logs]# ls
access.log  error.log  nginx.pid

[root@localhost logs]# bash /opt/scripts/14.sh 

[root@localhost logs]# ls
2023-07  access.log  error.log  nginx.pid

[root@localhost logs]# cd 2023-07/
[root@localhost 2023-07]# ls
access.log_2023-07-16

[root@localhost 2023-07]# cat access.log_2023-07-16
