Nginx:日志配置与日志定时分割备份

Posted 2023-02-14 陌生谁家年少

1.日志格式设置

• log_format

log_format main '$server_name $remote_addr - $remote_user [$time_local] "$request" '
                '$status $upstream_status $body_bytes_sent "$http_referer" '
                '"$http_user_agent" "$http_x_forwarded_for" '
                '$ssl_protocol $ssl_cipher $upstream_addr $request_time $upstream_response_time';

• 配置

http 
        ##
        # Logging Settings
        ##
        log_format main '$server_name $remote_addr - $remote_user [$time_local] "$request" '
                        '$status $upstream_status $body_bytes_sent "$http_referer" '
                        '"$http_user_agent" "$http_x_forwarded_for" '
                        '$ssl_protocol $ssl_cipher $upstream_addr $request_time $upstream_response_time';
        # access_log off;
        access_log /var/log/nginx/access.log main;
        error_log /var/log/nginx/error.log;

• 输出

localhost 171.168.1.3 - - [29/Jul/2020:14:16:12 +0800] "GET /nginx/xxx/xx/x?sign=xxxxx HTTP/1.1" 200 200 103 "https://xxx.example.com.cn/nginx/xx/xx/web?type=register&code=043tmemb1loe2A0h7lmb1HQemb1tmemF&state=123" "Mozilla/5.0 (Linux; android 9; CLT-AL00 Build/HUAWEICLT-AL00; wv) AppleWebKit/537.36 (Khtml, like Gecko) Version/4.0 Chrome/77.0.3865.120 MQQBrowser/6.2 TBS/045227 Mobile Safari/537.36 MMWEBID/1269 MicroMessenger/7.0.17.1720(0x27001135) Process/tools WeChat/arm64 NetType/WIFI Language/zh_CN ABI/arm64" "171.168.1.251:59808" - - 171.168.1.5:8070 0.021 0.020

2.日志定时分割脚本

• backup_log_nginx.sh

创建脚本，脚本为分割昨天的日志

#!/bin/bash
PATH_LOG=/var/log/nginx
YESTERDAY=$(date -d "yesterday" +%Y%m%d)

mv $PATH_LOG/access.log $PATH_LOG/access_$YESTERDAY.log

#USR1
kill -USR1 `ps axu | grep "nginx: master process" | grep -v grep | awk 'print $2'`
exit 0

• crontab

配置定时任务，每天0点执行日志分割脚本

#每天0点0分执行/root/devtools/backup_log_nginx.sh
0 0 * * * /root/devtools/backup_log_nginx.sh

3.效果

[root@MQ-SERVER nginx]# ls -l
