linux常用命令

9. nginx日志切割

#!/bin/bash
## 零点执行该脚本
## Nginx 日志文件所在的目录
LOGS_PATH1=/export/servers/nginx/logs/x.ppad5.paipai.com
LOGS_PATH2=/export/servers/nginx/logs/c.ppad5.paipai.com
## 获取昨天的 yyyy-MM-dd
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
## 移动文件
logs_name1=(x.ppad5.paipai.com_np x.ppad5.paipai.com_pv x.ppad5.paipai.com_access x.ppad5.paipai.com_error)
logs_name2=(c.ppad5.paipai.com_nc c.ppad5.paipai.com_access c.ppad5.paipai.com_error)
for((i=0;i<${#logs_name1[@]};i++));do mv ${LOGS_PATH1}/${logs_name1[i]}.log ${LOGS_PATH1}/${logs_name1[i]}_${YESTERDAY}.log;done
for((i=0;i<${#logs_name2[@]};i++));do mv ${LOGS_PATH2}/${logs_name2[i]}.log ${LOGS_PATH2}/${logs_name2[i]}_${YESTERDAY}.log;done
## 向 Nginx 主进程发送 USR1 信号。USR1 信号是重新打开日志文件

kill -USR1 $(cat /export/servers/nginx/run/nginx.pid)
