nginx日志切割脚本和webbench网站压力测试工具的部署及使用

每天定时切割 Nginx 日志的脚本
1) vi /usr/local/nginx/sbin/cut_nginx_log.sh

#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access_blog.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d
"yesterday" +"%m")/access_blog_$(date -d "yesterday" +"%Y%m%d").log
mv ${logs_path}access_ ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d
"yesterday" +"%m")/access_www_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`
crontab -e
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh

2) vi /usr/local/nginx/sbin/cut_nginx_log.sh

#!/bin/bash
nginx_app=/usr/local/nginx/sbin/nginx #设置 nginx 的目录
logs_dir=/usr/local/nginx/logs/ #log 目录
bak_dir=/usr/local/nginx/logs/bak/ #log 备份目录
#先把现有的 log 文件挪到备份目录临时存放
cd $logs_dir
echo “moving logs”
/bin/mv *.log $bak_dir
sleep 3
#重建 nginx log
echo “rebuild logs”
echo “$nginx_app -s reopen”
$nginx_app -s reopen
#按天打包 log 文件
echo “begining of tar”
cd $bak_dir
/bin/tar zcf `date +%Y%m%d`.tgz *.log
#删除备份目录的临时文件
echo “rm logs”
rm -f *.log
echo “done”
crontab -e
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh >/dev/null 2>&1

3) vi /etc/logrotate.conf

/usr/local/nginx/logs/*.log {
daily
missingok
rotate 7
compress
delaycompress
notifempty
create 640 root adm
sharedscripts
postrotate
[ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`
endscript
}

logrotate -vf /etc/logrotate.conf
